Precision molding capability
Engineered for extreme conditions
Specialized equipment and high-temperature mold systems support the demanding processing window of PEEK components.
PEEK processing expertise
Control the process behind the performance
PEEK is a semi-crystalline thermoplastic with exceptional mechanical strength and chemical resistance at elevated temperatures. Its performance depends on disciplined control of melt temperature, mold temperature, drying, and crystallinity.
High-temperature equipment
Processing equipment maintains the precise thermal window required for stable PEEK molding.
Crystallinity control
High-temperature mold systems support consistent crystallinity and reliable part performance.
Material discipline
Controlled drying helps maintain material quality, with maximum moisture below 0.02%.
Quality validation
Every production run receives dimensional and cosmetic inspection for high-value components.

Manufacturing workflow
Risk reduction built into every stage
Design support is integrated directly into manufacturing to help prevent defects and verify performance before full-scale production.
-
1
DFM Analysis
We review wall thickness, draft angles, rib structures, and gate locations to reduce warpage and internal voids, which are particularly important for PEEK.
-
2
Tooling and Mold Design
Custom mold layouts are engineered for material flow, high-temperature operation, and cooling efficiency.
-
3
T1 Sampling
Initial trials verify part dimensions and material properties before moving to full-scale production.
-
4
Production and Quality Control
Full-cycle manufacturing includes dimensional and cosmetic inspection, painting, laser marking, and assembly when required.
