What are Urethane Wheels? Urethane wheels are wheels made of molded urethane, also known as polyurethane. Urethane is an elastomer that comprises urethane carbamate linkages and is a portmanteau phrase for "elastic polymer." All of the advantages of metal, plastic, and rubber wheels are integrated in urethane wheels. They are more cost effective, more flexible, have better noise reduction, higher resilience, and are more resistant to impact, abrasion, and corrosion than metal. In terms of low temperatures, impact, cold flow, abrasion, and radiation resistance, urethane outperforms plastic. They can also reduce noise, are more resilient, have superior elastic memory, and...

Differences Between Polyurethane and Rubber Both rubber and polyurethane are regarded for their elastic, flexible properties. Each material is commonly used in the manufacturing of parts and components in the automotive industry. The largest user of polyurethane reaction injection-molded (RIM) parts is the automotive industry. Because it is typically more durable than rubber, polyurethane is used in applications that require continual exposure to stress or constant stretching and offer a degree of flex, with plenty of strength. Such body parts as fenders, bumpers, and spoilers are made of polyurethane. Rubber’s place in the automotive industry comes down to a single... Read More
Today, there are around 131 million wheelchair users around the world. Most are relying on the same decades-old technology to get around. That’s because the wheelchair, for all that it has done to improve the quality of people’s lives, has changed little over the course of the past generation. Until now. The digital technologies shaping the Fourth Industrial Revolution also have the potential to make substantial improvements to people’s quality of life. Here are three tech-driven start-ups and entrepreneurs working to bring the power of digital transformation to bear on the wheelchair. Read more: These 3 tech visionaries are reinventing... Read More
Rubbers are a family of polymeric materials based on the chemistry of natural rubber latex. While there are many synthetic rubbers in the market, they share a basic chemical composition with natural rubbers. Rubber is a cost-effective solution for many applications, but its physical properties often prevent superior performance. Unlike rubber, polyurethane offers higher load-bearing capacity, better compression set, and superior tolerance to greases, oils, oxygen, and ozone. Because rubber is biodegradable, it tends to rot and degrade over time with exposure to the elements. But, man-made polyurethane can be easily formulated to outlast rubber and stand up to sunlight...

The role of the rear wheel is to offer stability to the wheelchair, and also the ability for the user to self propel. In order to be able to manually self propel, the user must choose the large rear wheels. This offers the user independence as they don’t need to rely on another person to get around. Typically, more active wheelchair users will opt for the larger rear wheels. If the user has someone, for example a caregiver or family, who is going to push the wheelchair from behind all the time, then a smaller rear wheel is more suitable.... Read More
What Is a Hot Runner? During the plastic injection process a “Hot Runner” ensures that the plastic passing through the runner stays molten by heating the runner. Temperatures along the entire runner, from the barrel outlet of the injection molding machine to the gate at the mold, are in a constant state of flux. By using heating rods and heating rings near the runner, a high-temperature state is maintained and the plastic in the runner is kept molten. Generally, between operation runs, it is not necessary to open the runner to take out the plastic after the machine is shut... Read More
Installed on a 110-ton MD-S8000 all-electric injection molding machine, the Shot Maker will allow Niigata to change the shot sizes its running at the show from 2.75 to 4.37 to 6.53 oz. Niigata will be demonstrating the Shot Maker by molding a foldable phone holder from a family tool. The 6-cavity tool makes three different sizes of the phone holders, with two cavities forming one holder. The smallest shot size can make one holder, with the medium making four and the largest able to fill all six cavities. The tool was built to show off the both the Shot Maker... Read More
Thermoforming or vacuum forming is a common method of processing plastic materials, and vacuum formed products are ubiquitous in daily life. The process involves heating a plastic sheet until soft and then placing it over a mold. A vacuum then draws the soft sheet into the mold. The sheet is allowed to cool and is then removed from the mold. What is Vacuum Forming? Vacuum forming is a thermoforming process. The processing principle of vacuum forming is to heat and soften the thermoplastic plastic sheet, then stick the sheet on the mold, and vacuum the side of the coating, so... Read More
Many people do not understand what a mold is. A mold (sometimes called a mould) is a block of material with a hollowed-out cavity that has a shape cut into sides of the cavity. Liquid or pliable material is pushed into the cavity where it adopts the shape of the hollowed out section. After the liquid hardens or sets inside the mold, or the pliable material has been pressed into the shape of the mold, the item is removed from the mold. Molds are made from a variety of materials, such as metal, clay, or wood, and can be used... Read More
Do you know how the plastic products are made in our daily living? Bottle caps, bowls, auto parts, etc. Many of the plastic products that are common in life are injected by injection molding machines. When it comes to injection molding machines, many people should have no idea in their minds. Injection molding machines can manufacture limited to plastic products. In this article, we sort out the common injection molding machines with the different characteristics of different models? Let's take a look at the following. What is An Injection Molding Machine? Injection molding machine is a special machine for manufacturing... Read More
