— Frequently Asked Questions —

Q: What materials can you machine?

We work with a wide range of materials including aluminum alloys (7075, 6061), stainless steel (SUS304), brass, copper, and various engineering plastics such as ABS, PC, PE, PP, PS, and PA.

Q: What are the production processes for CNC machining?

Our CNC machining process includes design review, material selection, programming (CAM), precision milling/turning, deburring, surface finishing, quality inspection, and packaging. We follow strict process flow control to ensure consistency.

Q: What are the guidelines for injection molding materials?

Commonly used materials include ABS (impact-resistant), PC (high transparency), PE/PP (flexible, chemical-resistant), PS (rigid), and PA (nylon, high strength). Material selection depends on application requirements like strength, temperature, and chemical exposure.

Q: How long does it take to receive a prototype?

Most prototypes are completed within 3–5 working days after design approval. Delivery time may vary based on complexity and material availability.
