Mechanical Designer vs Mechanical Engineer
Both mechanical designers and mechanical engineers play crucial roles in the development of new products and systems. Although there are similarities between them, there are stark differences between the duties of a mechanical engineer and the duties of a mechanical designer.To get more news about mechanical cad, you can visit shine news official website.
Mechanical engineers work with other design professionals to take a project from the initial design stages to the final manufacturing or construction stages.
Often referred to as drafters, mechanical designers specialize in using 2D and 3D CAD design software to create highly precise technical designs and digital models.
The illustrations and models that a mechanical designer creates are based on the initial sketches made by the mechanical design engineer. A mechanical designer must follow the specifications and instructions the mechanical engineer provides. The aim of the process is to transform an initial sketch of an object or product into a complex and precise technical design ready for manufacturing.
What is a mechanical engineer?
Engineering broadly describes the use of science and technology to design, build, and use machines, structures, and engines. Engineering covers a wide array of careers in the STEM (Science, Technology, Engineering, and Math) fields, from pharmaceutical development to civil engineering to product development.
A mechanical engineer specializes in designing, building, and repairing complete mechanical systems and machines and their components. These systems and machines are usually intended to fulfill a particular function or purpose, such as a piece of medical equipment, an automotive engine, or an aeronautical component.
What do mechanical engineers do?
A mechanical engineer is involved in every phase of developing a product, component, machine, or structure. This includes material selection and part design, product and part testing, manufacturing, and vendor development.
Mechanical engineers use sophisticated 3D CAD modeling software to create the initial designs. The mechanical engineer then tests the designs using structural and thermal simulations generated by CAD software.
What are the qualities of a good mechanical engineer?
Good mechanical design engineers take a precise and thorough approach to every aspect of the design process. They are equipped with good analytical and technical skills focusing on exceptional knowledge of mechanics, CAD design software, and engineering drawing.
To succeed in their careers, mechanical engineers must have excellent knowledge of mathematics and physics and a high level of computer skills. They should understand every aspect of the machine or system they are creating.
As well as the practical functional aspects of their designs, mechanical engineers must also consider the ease of assembly, the cost of manufacturing, how the object will be disposed of, and other such macro-level factors.

How to choose the right extruder for PVC production
In the plastic industry, PVC is one of the plastic products with the largest output in the world. Plastic product manufacturers need to consider many aspects when choosing the core equipment such as extruder. In order to better produce high-quality plastic products, Jiangsu Xinrongplas Machinery Co., Ltd. simply provides you with some suggestions for selection. The extruders required for PVC production belong to plastic extruders, and PVC plastic extruders can be divided into single-screw plastic extruders, twin-screw plastic extruders and multi-screw extruders according to the number of screws. Both single-screw and twin-screw extruders are used in practice.Get more news about used pvc extruder,you can vist our website!
More than 20 years ago, the PVC production industry mostly used gradient single-screw plastic extruders. However, PVC is a heat-sensitive plastic. In order to prevent the pyrolysis of the material, the screw speed of the extruder should not be too high (the output is low) during the production process. Now with the emergence of a special extruder for PVC powder, no granulation is required, and the powder can be directly extruded to produce molded products. Now it is mainly used in the production of PVC soft materials.
In the production of PVC rigid products, the advanced conical counter-rotating twin-screw extruder is mainly used, and the price of this extruder is relatively appropriate. When using the conical double extruder, due to the special structure, the PVC powder will not generate excessive friction heat during extrusion, which can avoid the decomposition of the material to a limited extent, the extrusion volume of the equipment can be stabilized, the output of finished products is higher and Performance can be better guaranteed. In recent years, when producing rigid PVC products, we suggest that the conical twin-screw plastic extruder should be given priority.
Now a small number of plastic products factories are also using parallel twin-screw extruders for the production of PVC extruded pipes and profiles. However, for the two extruders mentioned above, the one-time investment cost of the equipment is high and the equipment maintenance is complicated. Especially when producing rigid PVC products, the damage to the equipment is greater than that of the cone double, which may The service life of the equipment in the later stage will be affected, so there are still relatively few applications at present.
After determining the form of the extruder, we also need to understand the specifications of plastic products at this time. By analyzing the amount of material according to the different specifications of the product, and then referring to "screw diameter and product specification size, output", a reasonable selection is made.
ushi chain limits conveyor belt use to orders after licking scandal
The operator of the major sushi restaurant chain Sushiro has said it will temporarily limit the use of conveyor belts to specifically ordered food after a customer was found to have misused and licked unused cups and sushi.Get more news about sushi tray,you can vist our website!
Akindo Sushiro Co. said in a press release Friday that customers will be asked to order food on a touch screen panel instead of taking ready-made food served on plates that travel on conveyor belts past numerous diners.
The move comes after videos of unhygienic behavior by customers at various restaurants racked up millions of views online, leading Akindo Sushiro to file a complaint against a customer earlier this week.
Sushi train restaurants have long been an iconic part of Japan’s food culture. Now, videos of people licking shared soy sauce bottles and messing with plates of food on conveyor belts are prompting critics to question their prospects in a Covid-conscious world.
Last week, a video taken at Sushiro, a popular sushi chain, went viral, showing a male customer licking his fingers and touching food as it came down the rotating belt. The man is also seen licking a condiment bottle and a cup that he places back onto a communal pile.
The prank has set off a deluge of criticism in Japan, where such acts are becoming more common and being called “#sushitero,” or “#sushiterrorism,” online.
The trend has rattled investors. Shares in Sushiro’s owner, Food & Life Companies Co Ltd, fell 4.8% last Tuesday, as the video circulated.
The company is taking the incident seriously. In a statement last Wednesday, Food & Life Companies said it had filed a police report against the customer, alleging damages. The firm also said it had received an apology from him, and that it had instructed restaurant staff to provide specially disinfected utensils or condiment containers to any customers who felt uneasy.
Sushiro is not the only company dealing with the problem. Two other leading conveyor belt sushi chains, Kura Sushi and Hamazushi, told CNN that they had experienced similar disruptions.
Preparation of cis-pinane via α-pinene hydrogenation in water
Amphiphilic mesoporous silica modified with trimethoxy (3,3,3-trifluoropropyl) silane (TFPS) and (3-aminopropyl) trimethoxysilane (APTS) was prepared by one-step synthesis. The structure and morphology of the mesoporous silica were characterized and confirmed by solid-state nuclear magnetic resonance, X-ray diffraction (XRD), N2 adsorption–desorption, Fourier transfer infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Meanwhile, the thermostability of the amphiphilic mesoporous silica was detected by thermogravimetric (TG) technique. Get more news about cis pinane,you can vist our website!
Highly dispersed Ru nanoparticles supported on such amphiphilic mesoporous silica (marked as Ru/MF@MN) were synthesized by wet impregnation method with the assistance of ultrasonic. The catalyst was characterized by X-ray photoelectron spectroscopy (XPS) and inductively coupled plasma-atomic emission spectrometry (ICP-AES). In water medium, Ru/MF@MN was used in α-pinene hydrogenation to prepare cis-pinane. Under the optimum reaction conditions (35 °C, 2 MPa H2, 1 h, m (H2O) : m (α-pinene) : m (Ru/MF@MN) = 200 : 60 : 1), 99.9% α-pinene conversion and 98.9% cis-pinane selectivity were obtained. When Ru/MF@MN was recycled six times, the conversion slightly decreased and the selectivity was nearly unchanged.
1. Introduction
cis-Pinane is a kind of significant industrial intermediate that is usually applied in medicine, materials and perfume owing to the high activity of its C2–H bond.1–4cis-Pinane is prepared by selective hydrogenation of α-pinene. Traditionally, α-pinene hydrogenation is commonly catalyzed by Pd/C5 or Pt/C,6 but the content of cis-pinane in products is very low. Moreover, carbon deposition or coking tended to occur due to the poor stability of carbon materials when the catalyst was recycled.7 Raney-Ni was also commonly used in the hydrogenation of α-pinene, but the reaction conditions were too harsh.8 When the hydrogenation of α-pinene was catalyzed by RuCl3·3H2O in water (160 °C, 5 MPa, 5 h), the α-pinene conversion could reach 99.7% and the cis-pinane selectivity was 98.3%.9 However, the stability of the catalyst was very poor.
3. Results and discussion
3.1 Synthesis and characterization of mesoporous silica
The water contact angles of four kinds of mesoporous silica were shown in Fig. 1. Interestingly, water contact angles continually increased with an increase in loading of fluorine. The results indicated that the hydrophobicity of mesoporous silica was enhanced. When the content of fluorine increased to 12.5%, the biggest water contact angle was obtained, which meant 12.5%MF@MN had the strongest hydrophobicity. It resulted in poor dispersity of such mesoporous silica in water. While the content of fluorine was 7.5%, the mesoporous silica with better wettability could disperse well in organic-aqueous biphase system. When Ru nanoparticles were supported on 7.5%MF@MN, 98.9% α-pinene was converted to cis-pinane and 99.9% conversion was achieved in water. So 7.5%MF@MN was selected as the optimum amphiphilic mesoporous silica for the following experiments.
2023 and the packaging industry
2022 was another strong year for the corrugated packaging industry in the UK. Not without its challenges, the corrugated industry continues to thrive as the switch from non-recyclable packaging materials remains a priority for many businesses as they endeavour to fulfil robust Environmental, Social and Governance (ESG) policies.Get more news about Custom Paper Box Packaging,you can vist our website!
Gareth Stell, Logson Group Sales Director offers comment on what he thinks 2023 will bring.
During 2022 paper prices stabilised after a turbulent couple of years attributed to the global challenges of the pandemic. And, the recycling market also buoyed, with recycling rates becoming healthier once more. The political landscape in the UK has not been helpful to business generally, so we hope that a period of stability in that arena can be enjoyed in 2023 and that this will impact positively on the manufacturing sector.
Despite the challenges of the year, our teams responded to higher production volumes with their usual professionalism, to support businesses making the switch to corrugated. Perhaps one thing that is very evident, is the experience that our teams have in developing packaging solutions that are innovative, material efficient and fit for purpose. Indeed, this resulted in us being named as UK Packaging company of the year for 2022 at the UK Packaging Awards, an accolade that truly reflects the status of the business and its ambition and drive for the future. We’re in a strong position as we begin 2023 and we look forward to ongoing investment for our teams reinforcing our position as a market leader in the UK.
The UK paper industry is a significant one to be part of. Statistics from the Confederation of Paper Industries (CPI) reports an annual turnover of £12bn giving employment to 62,000 employees.
This shows the size and stature of the industry and with volumes expected to be lower than the highs seen in the latter part of 2020 and through 2021, the demand for corrugated undoubtedly remains high. However, we believe that the main focus for our customers, both existing and prospective will be to find ways to maximise material efficiencies and maximise product protection through the supply chain.
Supporting external goals
We expect that our expertise will continue to be called upon to find solutions that replace non-recyclable solutions. Coupled with the Plastic Packaging Tax, which was introduced in April of 2022, it has only served to drive demand for fully recyclable packaging such as corrugated.
It’s not just about the outer box too. Fittings, dividers, and our bespoke packaging solutions all help to protect product, use material efficiency, and support sustainability goals.
high quality, low risk: Gelatin as preferred excipient for soft capsules
A softgel capsule is an edible package that is filled and formed simultaneously. It is meant to protect ingredients that are sensitive to light and oxygen-induced degradation, facilitate oral administration, and mask unpleasant tastes or smells[1]. Softgel capsules are increasingly preferred in the pharmaceutical field for their proprieties, but also by consumers, who perceive them as easier to swallow[2]. Indeed, demand for softgel capsules is continually growing: the global softgel capsule market is expected to grow at a compound annual growth rate (CAGR) of 7.72 percent by 2026[3].Get more news about Immune Soft Capsules,you can vist our website!
To meet growing demand and consumers’ formulation requirements, softgel capsule formulators must select the right shell excipient, compatible with fill material characteristics, to ensure a high-quality, low-risk, and robust product. Today’s softgel capsule formulators have several shell excipient options for new product development: gelatin or alternative capsule excipients, such as carrageenan and/or modified starch. When selecting a shell excipient, many product variables need to be considered, such as release profile and intended use, fill characteristics, shell/fill interactions, existing process capabilities, container/closure configuration, distribution channels, and the product’s target shelf life. Formulators need to have a complete process vision when developing a new soft-capsule product.
With a market share of more than 90 percent, gelatin is the preferred excipient for softgel capsules[4].Gelatin combines several advantages to be the excipient of choice for producing high-quality softgel capsules. This preference comes down to three of its features: its quality, versatility, and processability.
High-quality edible gelatin is available globally from multiple suppliers, so small and large users have good access to quality raw material. Gelatin is described in major pharmacopoeia monographs, is internationally regulated, and is processed under highly controlled conditions. It is produced only from edible parts of animal stock. The animal selection or source is controlled. The animal parts are handled under highly sanitary conditions and are by-products of food production, helping to reduce food waste. Gelatin is highly refined and far removed from the original animal source. For softgel, a subset of edible gelatin is needed. Gelatin suppliers are able to provide gelatin that is specific for soft gelatin capsule needs based on a well-defined raw-material specification.
Gelatin offers greater versatility when it comes to formulating a softgel capsule. Finished goods with a strong point of difference can be imagined and executed. The formulator can select a variety of gelatin types to further customize the capsule’s shell performance. Further tailoring of the capsule’s shell performance can be accomplished with additives. Gelatin’s amphoteric nature allows the gelatin to tolerate the addition of essential oils, flavors, oil-based colorants, water-soluble dyes, pigments, pearlescent, and fibers. It is even possible to add other hydrocolloids and polysaccharides to gelatin as functional fillers to provide unique release properties. Alternate capsule excipients have limitations in both the types and levels of additives that can be added. With gelatin, the expanded “tool chest” gives the formulator freedom to create a robust product with a true point of difference and unique functionality.

As we all know, clothing labels are an important part of clothing trimmings. They are more than just a piece of cloth or tags. They can clearly record the brand logo, clothing size, and ingredient list, place of origin, manufacturer, care information, etc. Many customers will decide whether to buy clothing based on the label. Therefore, labels are very important for product sales. This article also introduces various types of clothing labels from four perspectives.
What are the metal labels? Metal labels are metal tags & accessories for clothing, hats, or bags, which can be engraved with brand logos.
Metal labels have many types like aluminum labels, stainless steel labels, silver labels, copper labels, brass labels, zinc alloy labels, etc. Then, metal labels have wide usage and processes involve stamping, printing, laser cutting, etc.
What are the leather labels? Leather labels are one of the types of labels with leather material. we can also call them leather tags or leather patches. They have the types of artificial(PU), genuine(real), or suede(microfiber) leather labels.
It is ideal for clothing jackets, denim, caps, bags, etc. And all the leather labels can use printing, embossing, or gold/silver hot stamping way to add personalized logos and metal tags. And the adding ways include stitched on, ironed on, stuck on, or using Velcro.
This Cervical Traction 'Relaxer' Might Be the Answer to Your Neck
Neck and shoulder pain nags most of us from time to time, and unfortunately, studies show that it only gets worse as we age. While women tend to suffer from it more often than men, the truth is, chronic aches and pains can affect anyone at any time, whether they’re hunched over a computer all day or sleeping on a bad mattress at night.Get more news about traction pillow in china,you can vist our website!
The good news is, you don’t always have to shell out the big bucks to get some relief. Sure, fancy massages and weekly visits to the chiropractor can feel amazing, but there are quicker (and more affordable) solutions you may want to try first.
Right now, Amazon shoppers are swearing by the Neck and Shoulder Relaxer — a cervical traction device that promises to ease neck pain, promote cervical spine alignment, and even help treat symptoms of TMJ. In fact, the Relaxer has more than 55,000 reviews from happy customers who all say that it’s helped them with a variety of health problems. And best of all, it’s 44% off for a limited time!
“I’ve suffered with migraines for 35 years,” shared one reviewer, who said they often wake up with debilitating headaches that stem from neck and shoulder pain. “I figured I’d give this a shot to see if stretching before bed and first thing in the morning might help relieve the headache.”
“Unexpectedly, I have found [that spending just] about five minutes on this device puts me straight to sleep and surprisingly has led to the best night’s unmedicated sleep in years,” they continued.
Another reviewer said they were “astounded” by the immediate relief it offered.
“I suffer from degenerative disc disease in my neck and also have fibromyalgia,” the customer shared. “This one item has done more for me in 10 minutes than any amount of yoga, exercise, weight loss, physiotherapy, massage, medication ... you name it, ever could.”
While the Relaxer may not look too comfy at first-glance, it’s not meant to be used for long periods of time—just 10 minutes a day. Its V-shaped design is made of soft and flexible foam, which helps support proper curvature of the spine. Gentle massage nodes help ease muscle tension, and a strong, stable base keeps the Relaxer in place while you close your eyes and wait for it to work its magic.One of the things my physical therapist does for me is put my neck in traction for about 10 minutes at the end of my sessions [and it] makes a huge difference,” one reviewer said. “I wanted to find a way to do something similar for myself at home safely … Then I found this product. I use it about once a day—after work or before bed—and it helps stretch my neck in addition to the other exercises my PT has me do.”
Though it may take a few days to notice any changes, many customers say the Relaxer has quickly become an important part of their nightly routine. (And with good reason.)
What Makes Stainless Steel Fasteners Stand Out
Today, stainless steel fasteners such as bolts, nut rods, and washers help keep the important industries running. Without them, nothing would go on because they are a crucial aspect of successful projects.Get more news about stainless steel screws fasteners,you can vist our website!
Stainless Steel Bolts
Hex head bolts, carriage bolts, machine screws, shoulder bolts, and socket cap screws are among the most popular types of bolts.
Machine screws have a flat head at the tip and a threaded shaft that runs through the head. Because these screws are suitable for a wide range of applications, they come in various drive types and heads.
Carriage bolts have a countersunk head design. The bolt has a square portion underneath the head that prevents the bolt from being tightened further after the nut is in place.
Stainless Steel Screws
Wood screws comprise a smooth shank head with coarse spiraling threads that follow the straight shaft to a sharp tapering finish. They are often inserted in drilled holes to let them slip through and attach pieces of wood without splitting the wood.
Sheet metal screws have spiral threads running the length of a straight shaft with a tapering end. SMS may perforate sheet metal without drilling a hole because of the tapered end.
Stainless Steel Nuts
They're a type of fastener that's often used in combination with bolts. The most common types of nuts are castle nuts, cap nuts, square nuts, and T-nuts.
Stainless Steel Washers
Dock washers, backup rivet washers, fender washers, flat washers, structural washers, lock washers, and square washers are some of the typical washers used with threaded fasteners.
Stainless Steel Rivets
They have a permanent fastener that is extensively employed. Rivets, unlike screws and bolts, cannot be removed. They primarily keep plates or sheet metal in place.
Rivets are used in various applications, including steel civil construction, aviation components, automobiles, clothes, and ships. Rivets are used for a variety of purposes, depending on the application. As a result, there are many different rivets, but the two most prevalent are solid rivets and pop rivets.
