FAQ

Q: Which materials are best for electrical insulation?
A: ABS, PC, and PBT are common for insulation and flame-retardance; selection depends on operating conditions.

Q: Can you produce ultra-lightweight designs?
A: Yes—material choice and wall thickness optimization enable significant weight reduction while maintaining strength.

Q: What file formats do you accept?
A: We accept PDF, CAD, IGES, and STEP formats for mold and part design.

Q: How small can the order be?
A: Production orders start at around 500 pieces, but we also support smaller prototype runs.

Q: Do you meet industry certifications?
A: Yes—ISO 9001, IATF 16949, and RoHS compliance are available on request.

Q: How is the product packaged for shipping?
A: Products are protected in foam or bubble wrap, packed in labeled cartons, and crated for export when needed.
