Proprietary CAD files, tooling blueprints, and production volumes are isolated behind internal VLAN security perimeters. We execute binding NDAs prior to any file transmission, ensuring design exclusivity directly with factory management.
Every commercial delivery includes traceable quality assurance binders: EN 10204 Type 3.1 chemical and mechanical mill certs, heat treatment oven charts, RoHS/REACH substance declarations, and full FAI dimension reports.
From rapid airfreight prototypes (DAP/DDP) via DHL/FedEx to volume ocean container consignments (FOB Shenzhen, CIF Hamburg, DDP Long Beach), we provide full export customs documentation and bonded crating.
Clear, direct answers to common questions raised by procurement directors and quality assurance managers prior to tooling sign-off.
On critical CNC-milled and turned secondary features, we reliably maintain tolerances down to ±0.005 mm (±0.0002 in). On progressive die stamping and fine-blanked forms, standard production capability ranges from ±0.01 mm to ±0.02 mm depending on material thickness, ductility, and geometry. Final achievable limits are confirmed during our complimentary 24-hour DFM engineering review.
CNC machining, micro-turning, and sheet metal progressive stamping run directly in Sunmy-owned Shenzhen production centers. Specialized high-pressure casting and advanced automated surface conversions (such as MIL-A-8625 anodizing or electro-plating) operate within our audited ISO-compliant partner network. Crucially, all incoming raw materials, in-process CMM metrology, and 100% final First Article Inspection are performed directly by Sunmy engineers in-house.
We execute binding, enforceable bilateral Non-Disclosure Agreements (NDAs) prior to receiving any STEP, IGES, or 2D CAD engineering prints. You interface directly with our engineering personnel—never through third-party trading intermediaries or external commission agents. All digital files are secured within access-controlled server nodes, and dedicated customer dies remain the sole property of the client.
Standard production deliveries include EN 10204 3.1 certified raw material mill test reports, comprehensive CMM dimensional inspection sheets, and FAI documentation. For medical, aerospace, or automotive applications, we also provide heat-treatment microhardness charts, coating thickness verification, RoHS/REACH compliance letters, and full PPAP Level 3 documentation packs.
Yes. We specialize in low-volume prototype bridge manufacturing utilizing 5-axis CNC machining, wire EDM, laser cutting, and single-stage modular forming dies. This enables physical design and functional fit validation before capital commitment to multi-station progressive stamping dies or high-cavity hard tooling, mitigating financial and launch risk.
Comprehensive DFM engineering feedback and official quotations are delivered within 24 hours of CAD package receipt. Rapid prototypes are turned around in 3 to 7 business days. Progressive die design and fabrication typically require 20 to 35 calendar days depending on stage complexity, followed by immediate T1 sample air shipment and volume run scheduling.
