ODM Industrial Components Manufacturing Exporters & Exporter

On mission-critical aerospace and semiconductor features, we hold linear tolerances down to ±0.005 mm (0.0002 in) in temperature-controlled machining environments (20°C ±1°C). Geometric dimensioning and tolerancing (GD&T) attributes such as true position can be maintained within 0.008 mm relative to primary datums. We utilize automated Renishaw machine probing systems coupled with offline Zeiss CMM verification to document process capability metrics (Cp and Cpk > 1.33) across continuous batches.

Material authentication is fundamental to our ISO 9001:2015 protocol. Every inbound lot of bar stock, billet, and sheet metal is accompanied by mill test certificates (MTC) conforming to EN 10204 Type 3.1. We perform internal spectrometer chemical composition assays and Rockwell/Brinell hardness verification before raw stocks enter the production floor. All offcuts are labeled with heat numbers to maintain end-to-end traceability from finished part back to original ingot casting.

Precision CNC milling, Swiss turning, high-speed stamping, sub-assembly, and comprehensive CMM metrology are performed in Sunmy-owned Shenzhen facilities. Specialized surface conversion coatings (Type III hard anodizing, electroplating, chemical passivation) and foundry casting are executed by audited partner facilities that operate under our direct quality management oversight. Every single outsourced operation returns to Sunmy's quality laboratories for 100% CMM, coating thickness (X-ray fluorescence), and salt-spray adhesion testing prior to export clearance.

For rapid and comprehensive Design for Manufacturability (DFM) feedback, we prefer 3D CAD files in STEP (.step / .stp), Parasolid (.x_t), or IGES (.igs) format, paired with a complete 2D engineering drawing in PDF or DWG format that explicitly specifies critical dimensions, geometric tolerances (GD&T), surface finish expectations (Ra in µm or µin), material grades, and thermal heat treatment states. Our engineering group evaluates drafts within 24 hours to suggest tool optimization, stress relief, and cost-reduction opportunities.

We operate on a zero-leakage protocol. Prior to the upload or transmission of technical drawings, we execute an internationally binding Non-Disclosure Agreement (NDA). All engineering assets are stored on access-restricted, encrypted local servers with role-based permissions. CAD models are partitioned such that operators only view coordinates relevant to their specific machining setups. Your components are never displayed publicly without formal written authorization.

Leveraging our location in Shenzhen adjacent to major port terminals (Yantian, Shekou, Hong Kong International), we provide flexible incoterms (EXW, FOB, CIF, DDP). We partner with Tier-1 freight forwarders and air courier networks (DHL, FedEx, UPS) to achieve door-to-door transit in 3 to 5 business days for emergency prototype batches. For steady production runs, we manage buffer stock and blanket order releases to insulate overseas customers against ocean freight disruptions.
