Not sure? We recommend based on mechanical, thermal, chemical, and cost needs.
Typical Applications
Our glass-filled plastic parts serve demanding industries worldwide.
- Semiconductor and electronics equipment components
- Medical and laboratory device parts (non-patient-contact)
- Industrial automation and robotics: wear strips, bushings, guides, nests
- Pumps, valves, fluid handling: seats, seals, housings, impellers
- Aerospace and defense-related fixtures, insulation, structural plastics
- Automotive and transportation: brackets, housings, thermal/electrical insulation
- Food processing and packaging machinery parts (material-dependent)
Capabilities & Tolerances
Processes
CNC milling, turning, drilling, threading, counterboring, chamfering, slotting, profiling, engraving/marking.
Tolerance Guidance (GF Plastics)
- General dimensions up to 100 mm: ±0.02–0.05 mm
- 100–300 mm: ±0.05–0.10 mm typical
- Flatness/parallelism per drawing; H7/H8 bore equivalents possible
Surface Finish
As-machined Ra ~1.6–3.2 μm. Fine finishing possible; mirror finishes limited. Edge quality controlled with chamfers.
Design & Machining Guidelines
Optimized design helps us deliver cost-effective, high-quality GF plastic parts.
Fillets & Radii
Add generous internal radii to reduce stress concentration and edge chipping.
Wall Thickness
Avoid knife-edges; maintain robust sections to prevent cracking.
Threads
Prefer coarse threads; consider metal inserts for repeated assembly.
Holes & Slots
Break sharp edges; specify chamfers to reduce micro-chipping.
Burr Control
Design with accessible features for effective deburring; avoid deep narrow slots.
Heat Management
GF polymers are heat-sensitive; balanced feeds/speeds and coolant improve finish.
