Workpieces receive professional heat treatment for enhanced structural rigidity and superior overall mechanical properties. We additionally provide precision CNC machining and custom anti-corrosion surface treatments to satisfy varied aesthetic and long-term durability requirements. 
All finished components pass rigorous multi-aspect quality audits that verify dimensional precision, weld integrity and coating performance. Outfitted with heavy lifting machinery, we execute accurate, standardized product assembly, fully complying with bespoke industrial project criteria.

Stainless Steel Sandblasting

Our dedicated sandblasting service for stainless steel components strips away rust, contaminants and surface unevenness to thoroughly purify and level workpiece surfaces. The treatment yields a homogeneous, sleek and refined surface texture. Meanwhile, it remarkably strengthens the bonding force of surface coatings, laying a solid foundation to ensure steady and trustworthy results for later painting, electroplating and other surface finishing operations.

Our automatic shot blasting machinery completely removes mill scale, oxide film and residual rust from metal component surfaces. This sophisticated surface finishing solution greatly boosts surface purity and enhances the mechanical characteristics of base metals. It creates ideal preconditions for subsequent procedures including welding, coating and other surface treatment operations.

Powder Coating

We apply high-grade powder coating processes for surface finishing of metal parts. This superior surface treatment boasts outstanding sustained anti-corrosion performance and creates a sleek, even, abrasion-resistant protective film. It can retain steady color tone and delicate surface texture throughout the long service cycle of products.

01. Material Preparation
We are equipped with a full array of laser cutting, sawing and wire EDM equipment. All metal raw stocks are sized with high precision according to production drawings, establishing precise prerequisites for all subsequent fabrication stages.
02. Deburring & Beveling
Sharp edge burrs on workpieces are fully cleared to avoid scratching during assembly. Precision chamfering is implemented strictly following technical specifications on client drawings to guarantee reliable machining accuracy.
03. Sheet Metal Processing
We offer complete sheet metal forming services including rolling, bending and stamping. Metal plates can be shaped into custom structural components to match varied project design requirements.
04. Welding
High-performance welding processes connect metal blanks and prefabricated sheet metal parts. Professional process engineers provide ongoing on-site technical guidance throughout welding procedures to standardize all operational steps.
05. Weld Seam Grinding
Irregular weld joints are finely ground and polished following standardized processing norms, achieving sleek, tidy and defect-free welded surfaces.
06. Heat Treatment
Standard heat treatment techniques optimize the internal metallographic structure of metals. This grants finished products stable mechanical strength and outstanding durability for long-term operation.
07. Surface Treatment
Custom-tailored surface finishing solutions are available to satisfy two key demands: fulfilling clients' personalized aesthetic standards and delivering long-lasting anti-corrosion protection for component surfaces.
08. Quality Inspection
Comprehensive rigorous quality audits are carried out before shipment. The inspection scope covers precision dimension measurement, weld integrity checking and surface finish evaluation, ensuring all goods comply with industry norms and client technical demands.
