Casting Services Products & Exporter

Selection depends primarily on metal selection, annual production volume, and geometric complexity:

• Investment Casting (Lost Wax): Ideal for ferrous metals (Stainless Steel, Carbon Steel, Alloy Steel) and high-temperature alloys. Preferred for low-to-medium volumes (50 to 50,000 units) or parts with intricate internal undercuts and thick wall sections where die tooling is unfeasible.
• High-Pressure Die Casting (HPDC): Best suited for non-ferrous metals (Aluminum, Zinc, Magnesium) at high annual production volumes (5,000 to 1,000,000+ units). It yields faster cycle times, exceptional thin-wall capability (down to 1.2mm), and lower per-piece cost once tooling investment is amortized.

Standard linear dimensional casting tolerances follow ISO 8062 guidelines:

• Investment Casting: ISO 8062 CT4 to CT6 standard. Tolerances of ±0.1mm per 25mm are routinely achieved as-cast.
• Aluminum Die Casting: ISO 8062 CT4 to CT7 standard.
• Post-Cast CNC Machining: Critical mating surfaces, bearing bores, and threaded holes are precision machined to tight tolerances down to ±0.005mm using multi-axis CNC machining centers.

Internal micro-porosity is controlled using a comprehensive, engineering-led approach:

1. DFM & Simulation: Running Magmasoft or ProCAST mold flow and thermal solidification modeling to optimize runner, riser, and overflow positioning prior to mold machining.
2. Degassing & Melt Control: Utilizing rotary argon degassing for molten aluminum and vacuum refining for stainless steel melts to minimize dissolved hydrogen gas.
3. Vacuum Die Casting: Applying vacuum-assisted evacuation in HPDC tooling to clear air from the die cavity prior to shot injection.
4. Impregnation Treatment: For fluid containment castings (valve bodies, pump housings), secondary resin vacuum impregnation seals microscopic porosity channels, guaranteeing leak-free performance under pressure.

Every export shipment includes comprehensive quality documentation:

• 3.1 Material Certificate (EN 10204 3.1): Optical Emission Spectrometry chemical composition and mechanical batch test report (tensile, yield, elongation, hardness).
• First Article Inspection (FAI) Report: Full 100% layout dimensional audit report matching key balloon drawings.
• CMM Inspection Protocol: Coordinate measuring machine digital data printouts for critical feature geometric tolerances.
• NDT & Pressure Certification: X-ray radiographic inspection reports, dye-penetrant test certificates, and hydrostatic/pneumatic leak test reports where specified.

Typical project lead times follow structured milestones:

• DFM & Quote Response: 24 to 48 hours for engineering evaluation and cost optimization feedback.
• Rapid Prototypes (3D Printed Wax / CNC Billet): 7 to 14 business days.
• Hard Tooling Fabrication (Die Cast Molds / Wax Dies): 25 to 35 calendar days including T1 sample submission and initial FAI report.
• Mass Production Run: 20 to 30 calendar days depending on batch quantity and secondary plating or machining requirements.

Yes. Our reverse-engineering department utilizes high-precision optical 3D blue-light scanners to capture exact physical part geometries with sub-micron resolution. We convert physical components into STEP or IGES CAD models, perform material composition spectrometry, create technical 2D production drawings with recommended tolerances, and present complete DFM proposals for client approval before tooling.
