Part Size & Weight: From 5 g up to 8 kg; dimensions up to 800 × 800 × 200 mm
Process:
Investment (Lost-Wax) Casting: Silica-sol or water-glass slurry for intricate geometries
High-Pressure Die Casting: Cold-chamber machines (200 – 1 600 ton) for high-volume runs
Tolerances: As tight as ± 0.02 mm (per CT4–CT7 standards)
Surface Quality:
Roughness: Ra 1.6 – 6.3 µm (after shot- or sand-blasting)
Finishes: Powder coating, anodizing, electrophoretic painting, plating (Ni, Cu, Zn, Cr), polishing, silk-screen or laser marking
Certifications: ISO 9001:2015, RoHS, CE; material test reports (MTR), First-Article Inspection (FAI) available
Design Support: Free DFM analysis; accepts STEP, IGES, DWG, DXF files
MOQ & Packaging: Prototype from 1 pc; bulk in foam-lined cartons or wooden crates
Dual-Process Expertise
Combines the fine detail of investment casting with the speed and economy of high-pressure die casting.
Ultra-Tight Precision
Maintains repeatable tolerances down to ± 0.02 mm, reducing or eliminating post-machining.
Versatile Alloy Options
From lightweight aluminum to durable zinc and stainless steel, tailored to strength, weight and corrosion requirements.
One-Stop OEM/ODM Service
End-to-end workflow: pattern & mold design, casting, CNC machining, heat treatment, surface finishing and assembly.
Robust Quality Assurance
100 % inspection via CMM, X-ray/ultrasonic testing, spectrometer analysis and pressure/leak testing ensure compliance with global standards.
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.
| Industry | Typical Applications |
|---|---|
| Electronics & Telecom | Base-station enclosures, heat-sink housings |
| Automotive & EV | Sensor brackets, transmission components |
| Medical Devices | Surgical instrument bodies, implant fixtures |
| Industrial Machinery | Pump impellers, valve bodies, gearbox shells |
| Consumer Products | Power-tool housings, decorative hardware |
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.
