Professional precision metal casting services offering die casting, investment (lost-wax) and precision machining for a wide range of alloys — including aluminum, stainless steel, iron, brass and zinc. Services accept customer 2D (PDF/CAD) and 3D (IGES/STEP) drawings and are available for OEM/ODM production from single prototypes to large batches.
Materials available: Aluminum, Stainless Steel, Iron, Aluminum Alloys, Brass (and other common casting alloys).
Drawing formats accepted: 2D (PDF/CAD) and 3D (IGES/STEP).
Quality & certification: ISO9001, TS16949 and RoHS compliance with strict 100% inspection.
Customization: Custom size, surface finishing and material swaps available (custom options may add a small per-piece fee).
Packaging: Bubble wrap + carton + wooden case (example single package 30 × 30 × 30 cm; gross weight ~0.5 kg).
Typical lead times:
1–100 pcs: ~10 days
101–500 pcs: ~15 days
501–1000 pcs: ~20 days
1000 pcs: negotiable.
Sample pricing (indicative):
1–499 pcs: US$2.50 / pc
500–4,999 pcs: US$1.60 / pc
≥5,000 pcs: US$0.50 / pc.
Material versatility: From decorative copper/brass pieces to structural stainless and iron components — suitable for many industries.
Engineering-ready: Directly accept CAD/STEP files so your prototype-to-production transition is fast and accurate.
Certified quality: Production under internationally recognized standards (ISO9001/TS16949) and RoHS compliance for regulated markets.
Reliable inspection: 100% inspection policy reduces defect risk and improves first-pass yield.
Flexible volumes & pricing: Competitive tiered pricing supports single prototypes up through mass production runs.
Industrial & Mechanical Parts: Pump housings, valve bodies, gears and structural castings.
Automotive & Transportation: Brackets, fittings and medium-precision components suited for aftermarket and OEM use.
Medical & Instrumentation: Small, precise castings for non-implant applications and instrument housings (with appropriate material selection).
Architecture & Decorative Hardware: Custom brass and bronze fittings, trims and decorative elements.
Prototyping & Low-Volume Manufacturing: Rapid iteration and short runs before investing in large tooling.
Sustainability: Growing customer demand for recycled alloys and greener foundry processes — suppliers adapting to lower-emission, reclaimed-metal workflows.
Digital integration: Greater use of CAD/CAM, 3D-printed patterns, and automated inspection (CMM) to reduce lead times and improve tolerances.
Advanced finishes: Increased adoption of specialized coatings (anti-corrosion, anti-wear, matte and textured finishes) to meet industry and aesthetic demands.
Micro-precision casting: Rising need for smaller, tighter-tolerance parts in medical devices and electronics — investment casting and precision machining are well placed for this shift.
Q — What file formats do you need to quote and manufacture?
A — We accept 2D PDF/CAD and 3D IGES/STEP files for quoting and production to ensure accurate tooling and machining.
Q — Do you perform quality inspection on each part?
A — Yes. The process includes strict 100% inspection so each delivered part meets the customer drawing and QC standards.
Q — Can I order a single prototype?
A — Yes. Short runs and single prototypes are supported; custom options (size, finish, material) are available from 1 piece with small per-piece fees.
Q — What are typical lead times for production?
A — Typical lead times are ~10 days for up to 100 pcs, ~15 days for up to 500 pcs and ~20 days for up to 1,000 pcs; larger runs are negotiable.
Q — What certifications back your production?
A — Production follows ISO9001 and TS16949 systems and conforms to RoHS where applicable.
