In this process, the material is heated until it reaches a molten state, then injected into a mold under high pressure. The mold defines the shape of the final product, and once the material cools and solidifies, the part is ejected from the mold.

Injection molding is used to create highly detailed and complex components, making it ideal for producing medical device parts, automotive components, and consumer goods. The ability to create complex shapes with precise tolerances and a variety of hardness levels makes injection molding a popular choice for many industries.

Other Processing Techniques

In addition to extrusion and injection molding, polyether TPU can also be processed using other advanced manufacturing techniques such as blow molding, thermoforming, and 3D printing. Each of these methods offers unique advantages for creating products in specific shapes, sizes, and forms.

Blow molding is used to create hollow products, such as protective cases and tanks, from polyether TPU. This process allows manufacturers to produce lightweight, durable parts that are resistant to impact and wear.
Thermoforming is a technique used to create products from thin sheets of polyether TPU, often used in packaging and protective covers.
3D printing or additive manufacturing enables the creation of highly customized parts, which is particularly useful in the medical and prototype industries.
