Mechanical Products

A: We accept 2D and 3D CAD files including STEP, IGES, DXF, DWG, PDF, and SolidWorks models. Detailed PDF drawings with tolerance callouts, surface finish requirements, and thread specifications are required for accurate quotation.

A: All raw materials (carbon steel, alloy steel, stainless steel) are procured from certified mills. We require and verify Mill Test Certificates (MTC) and can perform third-party chemical and mechanical testing (such as SGS or TÜV) upon request before machining begins.

A: Sample production typically takes 15 to 25 days depending on tooling requirements and complexity. Mass production orders generally range from 30 to 45 days, confirmed upon order placement and drawing finalization.

A: Depending on the application environment, we provide zinc plating (clear, yellow, or black), hot-dip galvanizing, industrial powder coating, black oxide, and multi-layer epoxy priming designed to pass strict salt spray test requirements.

A: Yes. For load-bearing structures and mining equipment components, our in-house inspectors or certified third-party inspectors perform Non-Destructive Testing (NDT), including Magnetic Particle Testing (MT) and Ultrasonic Testing (UT), and supply inspection reports with the shipment.

A: MOQ depends on the manufacturing process. For CNC machined components, smaller batch runs are acceptable. For parts requiring dedicated stamping dies, forging molds, or casting patterns, the MOQ is evaluated based on tooling amortization and material setup costs.

A: We implement First Article Inspection (FAI) with complete CMM dimensional reports for client approval before batch production. During production, operators perform routine self-checks, and our QA team conducts patrol inspections and final pre-shipment inspections (AQL standards).
