2. Key Selling Points

1. Dual-Process Expertise
   Combines the fine detail of investment casting with the speed and economy of high-pressure die casting.

2. Ultra-Tight Precision
   Maintains repeatable tolerances down to ± 0.02 mm, reducing or eliminating post-machining.

3. Versatile Alloy Options
   From lightweight aluminum to durable zinc and stainless steel, tailored to strength, weight and corrosion requirements.

4. One-Stop OEM/ODM Service
   End-to-end workflow: pattern & mold design, casting, CNC machining, heat treatment, surface finishing and assembly.

5. Robust Quality Assurance
   100 % inspection via CMM, X-ray/ultrasonic testing, spectrometer analysis and pressure/leak testing ensure compliance with global standards.

3. Future Trends

• Additive-Hybrid Tooling: SLA/DLP 3D-printed patterns for faster prototype iteration and complex core geometry.

• Sustainable Casting: Increased use of recycled alloys and eco-friendly binders to meet circular-economy goals.

• Smart Factory Integration: IIoT sensors on die-casting machines for real-time monitoring, predictive maintenance and digital twins.

5. Frequently Asked Questions

Q1: Can I order a single prototype piece?
A: Yes—MOQ is 1 pc. Rapid prototypes available in 7–10 days.

Q2: What are your standard lead times?
A: Prototypes in 7–10 days; mass production in 15–30 days after sample approval (depending on volume & complexity).

Q3: Which CAD formats do you support?
A: STEP, IGES, DWG, DXF—3D models preferred for fastest tooling development.

Q4: How do you control porosity and surface integrity?
A: Investment casting uses controlled slurry and sintering; die casting employs vacuum-assist and optimized gating to minimize gas entrapment.

Q5: What surface treatments can you apply?
A: Powder coating, anodizing, electrophoretic paint, plating, polishing, blasting, silk-screen and laser marking.

Q6: How are parts packed and shipped?
A: Packed in foam-lined cartons or on wooden pallets; FOB, CIF or DDP shipping terms available to suit your logistics needs.
