OEM Customization Service
Material Options: Choice of SS316, SS304, or specialized stainless steel alloys, selected according to operating conditions and corrosion requirements.
Geometries & Internal Design: Customization of complex external shapes (curved, square, or irregular geometries) and internal features, including reinforcing ribs, support frames, slots, partitions, and fluid channels.
Dimensions & Hole/Thread Specifications: Full control over length, width, thickness, and diameter, alongside precision machining for hole spacing, depth, and specific internal or external thread pitches.
Surface Treatments: Options including brushed, mirror polished, sandblasted, electropolished, phosphated, or chemically passivated finishes to enhance corrosion performance or surface aesthetics.
Custom Order Workflow
Input Submission
Customer provides 2D/3D CAD drawings, physical samples, or both.
DFM Analysis
Engineering review of structural feasibility, tolerance matching, and casting/machining process selection.
Blank or Finished Production
Production of initial casting blanks followed by optional CNC machining and surface finishing according to specifications.
Quality Inspection & Delivery
Verification of chemical composition, critical dimensions, and protective packaging prior to dispatch.
Packaging & Export Shipping
We implement rigorous export packaging standards to help protect precision surfaces, seals, and threads through long-distance ocean and air transport.
Individual Unit Protection: Each finished part is sealed in anti-scratch bubble film, protective plastic mesh, or VCI (Vapor Corrosion Inhibitor) bags to block moisture and prevent surface abrasion.
Carton & Structural Cushioning: Heavy-duty, corrugated outer cartons equipped with anti-shock foam inserts or custom cardboard dividers to eliminate internal movement and collision during transit.
Palletizing & Wooden Crates: ISPM 15-compliant, non-fumigation wooden crates or solid pallets secured with edge protectors, industrial strapping, and waterproof stretch film to withstand multi-tier stacking and forklift handling.
Logistics & Warehousing Ready: All outer packages are clearly marked with shipping marks, gross/net weights, and part numbers for streamlined Customs clearance and efficient receiving at your distribution warehouse.

FAQ
Q: Can you perform reverse engineering from a single physical sample without CAD drawings?
A: Yes, we support reverse engineering from customer samples.
Q: Do you sign a Non-Disclosure Agreement (NDA) to protect our proprietary component designs?
A: Yes, we routinely execute formal legal NDAs to safeguard your custom engineered drawings and intellectual property.
Q: How do you verify and report chemical composition accuracy before pouring the metal?
A: We inspect molten metal using in-house optical emission spectrometers and provide material test certificates per batch.
Q: What is your standard policy regarding tooling ownership for custom OEM projects?
A: Tooling remains your exclusive property and is used solely for fulfilling your specific manufacturing orders.
Q: How do you handle dimensional non-conformities if received parts exceed specified tolerances?
A: We review inspection records, accept verified returns, and provide fast-track replacement or corrective account credit.
Q: Do you support third-party factory audits and pre-shipment product inspections?
A: Yes, third-party inspections are supported upon customer request.
Q: Can you accommodate design modifications after mold fabrication has already been completed?
A: Minor tool modifications are often workable; major structural changes require engineering evaluation and potential tool rework.
Q: What secondary pressure or non-destructive testing options do you perform in-house?
A: We perform hydrostatic, pneumatic pressure testing, and dye penetrant inspection in-house, with NDT/X-ray options available via accredited partners..
Q: How do you prevent internal casting defects in complex, thick-walled valve geometries?
A: We use solidification simulation software to optimize gate placement, riser design, and thermal mold parameters.
