The process for injection molding thermoplastic elastomers (TPEs) requires precise control of the molding conditions, including temperature, pressure, and cooling time, to ensure consistent and high-quality parts. The process involves the following steps:

Injection molding with thermoplastic elastomers (TPEs) is a manufacturing process where TPE material is melted and injected into a mold cavity to form a specific shape. TPEs are a type of polymer that has both plastic and rubber-like properties, making them suitable for applications that require both flexibility and strength. The resulting molded part can have a wide range of physical and mechanical properties, depending on the specific TPE material used and the molding conditions. Injection molding with TPEs is commonly used by a variety of industries, including automotive, consumer goods, and medical devices.

Thermoset plastics are generally stronger than thermoplastic materials due to the three-dimensional network of bonds (crosslinking), and are also better suited to high-temperature applications. They have high mechanical strength and rigidity and are frequently used to replace metals, reducing the weight by as much as 75%. Thermoset materials are often used in vehicle engine compartments, oil pump and thermostat housings, water inlets & outlets and impellers. Brake linings and disk brake pads can also be manufactured in thermoset plastic.
