Technical Capabilities & Contract Manufacturing FAQ

Essential engineering specifications, raw material standards, tolerance thresholds, and export logistics details for procurement teams and industrial clients.

What CAD/CAM file formats does Sameta Metal Pro accept for quoting?

We accept native and universal 3D CAD files (.STEP, .STP, .IGES, .SLDPRT, .IPT) as well as 2D engineering drawings (.DXF, .DWG, .PDF) with critical dimension callouts, bend angles, and surface finish requirements. Our engineering team can also assist with Design for Manufacturability (DFM) reviews to optimize sheet metal part yields and lower production costs.

What tolerances do you maintain across cutting, bending, and welding?

Our standard manufacturing tolerance conforms to ISO 2768-m (Medium). We achieve ±0.1 mm repeatability on fiber laser cutting, ±0.2 mm linear and ±0.5° angular tolerances on CNC press brake bending, and structural welding conforming to AWS D1.1. Precision fixtures and automated inspection ensure continuous repeatability across high-volume production runs.

How does your 9-stage pre-treatment and powder coating protect against rust?

Components undergo an automated 9-stage chemical immersion pre-treatment featuring degreasing, derusting, and zinc/iron phosphating passivation before electrostatic powder coating. This produces an impervious 60–80 μm dry film thickness (DFT) with 500+ hours ASTM B117 salt-spray corrosion resistance and ASTM D3359 cross-hatch adhesion compliance for demanding industrial environments.

Can Sameta handle turnkey contract manufacturing and sea container export?

Yes. Situated in Chennai within close proximity to major international maritime sea ports (Chennai Port & Kamarajar Ennore Port), we manage end-to-end turnkey OEM/ODM contracts. We provide complete 100% MTC heat traceability, custom branding, VCI anti-corrosion barrier packaging, ISPM-15 certified fumigated wooden crating, and direct stuffing into 20ft, 40ft, and 40ft High Cube containers for clients across North America, Europe, Singapore, and the Middle East.
