Polyimide Direct Formed Parts
Precision Parts Engineered for Extreme Operating Conditions
The direct forming process is designed for the production of high-precision series components manufactured from high-temperature plastics. During production, high-speed mechanical or hydraulic presses compact polymer powder directly inside precision mould cavities. The formed blanks are then sintered for several hours at elevated temperatures in an oxygen-free environment to achieve their final material performance
Why Choose Direct Forming?
Built for Heat, Load & Demanding Environments
Direct formed components offer exceptional dimensional stability while eliminating weld lines commonly associated with alternative manufacturing methods. These parts are engineered for applications exposed to elevated temperatures, high loads, rapid operating speeds, and demanding pressure conditions – even in dry-running or low-lubrication environments.
With excellent purity levels and reliable temperature resistance ranging from -270°C to 300°C, direct formed components perform exceptionally well in vacuum systems, cryogenic environments, and extreme thermal applications.
Efficiency Beyond Performance
Direct forming technology enables highly efficient material utilization compared with conventional manufacturing approaches. For simpler geometries, secondary machining may be reduced or eliminated entirely. Combined with short production cycles, the process supports economical, repeatable series production, particularly for larger production volumes.
High-Performance Polyimide Grades for Direct Formed Parts
Our range of advanced non-melting polyimide grades has been developed specifically for direct forming applications. These materials deliver outstanding thermal-oxidative stability, high mechanical strength, and dependable performance under demanding operating conditions.
Minimal mass loss at temperatures approaching 400°C makes these materials highly suitable for heavily loaded applications operating above 300°C.
High modulus, excellent wear and friction behaviour, and exceptional creep resistance distinguish these advanced polyimide materials in applications where conventional high-performance materials may reach their limits.
