What is Polyimide (PI)?

Polyimide (PI) – Polyimide (PI) exists as both thermoplastic and thermosetting resins and is a class of polymers known for their excellent heat resistance and flame retardancy. Thermoplastic polyimide is a special engineering plastic developed from PI, possessing excellent thermoplastic processing properties. It can be processed using all PI processing methods and is suitable for extrusion and injection molding.
The rigid structure of polyimide gives it a high glass transition temperature (Tg > 300°C), endowing it with good mechanical strength and high modulus. Therefore, even at temperatures above 260°C, this material maintains high levels of strength, dimensional stability, and creep resistance. Its low wear rate, ability to operate under unlubricated conditions, and high pV value make it ideal for applications involving harsh friction and wear, extending service life and reducing maintenance costs.

Polyimide Injection Molding Process

Polyimide injection molding involves injecting molten polyimide into a specific mold on an injection molding machine. The basic process includes injection, stamping, compaction, and cooling. This technology can produce complex and intricate shapes. However, polyimide processing requires high temperatures and releases corrosive gases. Therefore, special attention must be paid to mold design, molding equipment, and overall material handling. Thermoplastic polyimide injection molding is particularly suitable for one-time molding of complex polyimide molded parts, eliminating the need for secondary processing and solving the problems of high processing difficulty and limited product forms associated with traditional PI molding processes.

Seamless Transition from Prototype to Full Production

Our prototype molds are designed with scalability in mind. Once your prototype is complete, the same modular steel inserts can be upgraded to accommodate higher production volumes without requiring a complete mold rebuild. With just a durability upgrade to the prototype molds, our process enables up to 250,000 cycles of mass production. This avoids the downtime and costs commonly associated with transitioning from prototyping to mass production. With our streamlined and efficient processes, you can transition from the concept phase to mass production faster and more efficiently, maintaining precision and quality throughout the process.

PI Injection Molding Factory

Our factory is fully equipped to meet your high-volume, high-speed production needs. We have over 130 presses, ranging in tonnage from 40 tons to 2200 tons, ensuring every project meets the required precision specifications. In addition, we have a well-equipped on-site tooling and CNC machine shop for press maintenance, mold repair, and value-added services such as machining and custom or other surface treatments to meet your needs. With our extensive expertise and state-of-the-art injection molding machines, we use a wide variety of high-performance PI plastics for vertical, horizontal, and 45-degree angle injection molding.
