Material Versatility — Ideal for decorative alloys (copper/brass) and structural metals (stainless, iron, aluminum).
Design Flexibility — Works directly from CAD/STEP files for fast prototyping to production.
Certified Quality — ISO9001 & TS16949 compliance plus RoHS helps meet industry and regulatory needs.
Full Inspection — 100% inspection reduces risk of defects and returns.
Scalable Pricing & MOQ — Reasonable pricing across prototype runs and volume production.
Custom sizing, surface treatments and material swaps available (additional small per-piece fees). Minimum order for some customizations can be 1 piece — useful for prototyping. Lead times and unit pricing scale with quantity.
Common post-process finishes: polishing, plating, passivation, painting, sandblasting, and custom surface treatments to meet aesthetic or functional requirements.
Industrial Components: Precision parts for pumps, valves, fittings, and machine assemblies.
Medical Devices & Instruments: Small, high-precision components with biocompatible alloys or specific certifications.
Agricultural & Heavy Equipment: Durable cast parts that require wear resistance.
Decorative Hardware & Architectural Elements: Custom bronze/copper/brass fittings and ornaments.
Prototyping & Low-Volume Production: One-off samples or short runs before full tooling.
Sustainable Casting: Increased demand for recycled alloys and lower-emission foundry processes.
Digital Manufacturing: Closer integration of CAD/CAM and automated inspection for faster iteration.
Advanced Surface Engineering: Long-lasting anti-corrosion and anti-wear coatings for harsh environments.
Micro & Miniature Casting: Growing need for small, high-precision components in medical and electronics industries.
Q: What drawing files do you need to start?
A: Submit 2D PDFs/CAD or 3D formats such as IGES or STEP. These are standard inputs that speed up quotation and tooling.
Q: Do you inspect every part?
A: Yes — the facility performs strict 100% inspection to ensure parts match customer drawings and quality standards.
Q: Can I order a single prototype?
A: Yes — prototype and small orders are supported (example pricing shown for low-volume). Customization options may carry a small per-piece fee.
Q: What are typical production lead times?
A: Small batches (up to 100 pcs) can be completed in about 10 days; larger batches take longer and timelines are negotiable for very large runs.
Q: Are surface finishes and secondary machining supported?
A: Yes — a wide range of post-processing, finishing and machining services are available to meet functional and cosmetic needs.
