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.

1

Fillets & Radii

Add generous internal radii to reduce stress concentration and edge chipping.

2

Wall Thickness

Avoid knife-edges; maintain robust sections to prevent cracking.

3

Threads

Prefer coarse threads; consider metal inserts for repeated assembly.

4

Holes & Slots

Break sharp edges; specify chamfers to reduce micro-chipping.

5

Burr Control

Design with accessible features for effective deburring; avoid deep narrow slots.

6

Heat Management

GF polymers are heat-sensitive; balanced feeds/speeds and coolant improve finish.
