Thermoplastics

January 30, 2019
Plastic

Thermoplastics are polymers, which soften (becomes pliable and plastic) and melt when heated. In the melted conditions thermoplastics may be formed by various methods (injection molding, extrusion, Thermoforming). No new cross-links form (no chemical curing) when a thermoplastic cools and harden. Thermoplastics may be reprocessed (re-melt) many times. Molecules of most of thermoplastics combine long polymer chains alternating with monomer units. Thermoplastic materials may contain filler materials in form of powder or fibers, providing improvement of specific material properties...

Three Essential Items You Need Before You Can Injection Mold Manufacture Anything

Many of the prospective clients we speak with have an incomplete understanding of what exactly is required to produce a product at scale. There’s a lot that goes into an injection molded prototype or final product but the big three are absolutely essential. Here’s the big picture: What is Required For Injection Molding A computer design (CAD software file) of your part. Creative Mechanisms specializes in creating novel designs from “napkin-sketch” concepts and...

Once we have designed your initial prototype you need to think about the next step in the production process: creating a pre-production prototype. If you’re unsure as to the difference between “initial” and “pre-production” prototypes, it’s relatively simple: Initial prototypes are typically created using CNC machines and/or 3D printers. They are simpler, cheaper, and faster to produce. The most difficult part of initial prototype production is getting the design (CAD) correct. Generally...

Thermoplastic Polyurethane

December 3, 2018
Plastic

Thermoplastic polyurethane (TPU) is an elastomer that is fully thermoplastic. Like all thermoplastic elastomers, TPU is elastic and melt-processable. Further, it can be processed on extrusion as well as injection, blow and compression molding equipment. It can be vacuum-formed or solution-coated and is well suited for a wide variety of fabrication methodologies. TPU can even be colored through a number of processes. But more so than any other thermoplastic elastomer,...

Design teams are always trying to come up with something better—better shapes and designs, better performance, better materials, and most importantly, a better cost. If there's a way to give their product an edge over the competition, the design team will do everything they can to incorporate it into their process and product. Cost, of course, is a huge factor. After all, there is only so much you can do...

3 Tips for Choosing Better Wheelchair Wheels

November 7, 2018
Businessman in wheelchair

When configuring your wheelchair, it’s important to consider,  what wheels you need.  The choice you make will depend on your primary use, be it indoor or outdoor, plus the terrain and the activity involved. And making the right choice can be crucial. Someone with a pain condition really doesn’t need a lot of vibration, and other users may value speed as part of their sense of independence. Here’s the information you...

Rubber Versus Pneumatic Wheels

October 30, 2018
Rubber Versus Pneumatic Wheels

Most tires are constructed from some form of rubber. But, "rubber tires" usually refers to tires made entirely from solid rubber. Pneumatic tires are the typical tires we are use to having on our cars and bicycles. They have a solid rubber surface, but the inside is inflated with air. Advantages Solid rubber tires cannot go flat. They can get damaged, but it is unlikely that one incident will render...

What is Polyethylene terephthalate (PETE or PET), and What is it Used For

What is Polyethylene terephthalate (PETE or PET), and What is it Used For? Polyethylene terephthalate (PETE or PET) is the most commonly used thermoplastic polymer in the world and is better known in the textile industry by the trade name “polyester.” It is a naturally transparent and semi-crystalline plastic widely used as a fiber for clothing, as an effective moisture barrier with wide applicability in bottling and packaging (known in these cases as...

Thermoset Plastics – Polyurethane

October 19, 2018
Plastics

Polyurethane -- Polyurethanes are widely used in flexible and rigid foams, durable elastomers and high performance adhesives and sealants, fibers, seals, gaskets, condoms, carpet underlayment, and hard plastic parts. Polyurethane products are often called "urethanes". Uses - Over three quarters of the consumption of polyurethane products is in the form of foams, with flexible and rigid types being roughly equal in market size. Polyurethane materials are also used in coatings and...

Materials: Plastics

October 12, 2018
polymer

Introduction Humans have taken advantage of the versatility of polymers for centuries in the form of oils, tars, resins, and gums. However, it was not until the industrial revolution that the modern polymer industry began to develop. In the late 1830s, Charles Goodyear succeeded in producing a useful form of natural rubber through a process known as "vulcanization." Some 40 years later, Celluloid (a hard plastic formed from nitrocellulose) was...
