Stainless Steel Bracket Silicone Sol Precision Casting Polishing For Hardware Structural Components
This Stainless Steel Bracket acts as a load-bearing and positioning element in hardware structural assemblies, equipment mounting frames, and industrial support systems. Weighing 0.8 kg with overall dimensions of 120 × 80 × 150 mm, it is produced by our in-house Silicone Sol Precision Casting process followed by polishing, then finished with CNC machining for hole positions. SUS 316 stainless steel is chosen here for its corrosion resistance in humid, outdoor, and chemically exposed environments — a bracket in these conditions has to hold its geometry without rusting, maintain hole position accuracy over long service, and keep a clean surface appearance for visible structural applications.
Matech's one-stop approach, covering wax pattern making, silicone sol shell casting, solution heat treatment, CNC machining (hole positions, mounting faces), polishing and shot blasting, dimensional inspection, and engineered packing, ensures this bracket offers excellent hole position accuracy, tight tolerances on mounting interfaces, and a clean polished surface.

Our Advantages
Technical Advantages
Our silicone sol shell process produces brackets with smooth surfaces and accurate detail straight out of the mold, which is why this 0.8 kg part reaches CT5–CT6 tolerance without heavy machining. Fewer machining passes means lower cost and shorter lead time compared to sand casting routes.
Silicone sol casting handles thin walls (2.0 mm minimum here) but is sensitive to sharp internal corners and abrupt section changes. Our review flags these areas and recommends fillet radii and transition tapers that fill cleanly and avoid hot spots during solidification.
For visible stainless brackets, surface appearance matters as much as dimensions. Polishing is performed to a defined finish standard, followed by shot blasting where specified, with surface roughness verified before packing.
Service Advantages-总部接待区 1 拷贝
Material Advantages
Every incoming SUS 316 batch is checked by spectrometer against JIS H 5302 requirements, with particular attention to molybdenum and nickel content — the elements that give 316 its resistance to chlorides and chemical exposure.
Solution heat treatment is applied to relieve casting stress and homogenize the austenitic structure, which improves both machinability and long-term dimensional stability — important for a bracket that must stay aligned over years of service.
Beyond 316, we cast 304, duplex, and other corrosion-resistant grades. If your bracket sees stronger chemical exposure or higher mechanical load, we can recommend a grade and adjust the casting and heat treatment route accordingly.
Service Advantages
Brackets that combine casting, machining, and cosmetic polishing need coordinated planning. Your project manager aligns the foundry, machine shop, and finishing team on one schedule, so surface finish requirements are not lost between process steps.
Before batch production, we provide a first-article report that includes hole position measurement, mounting face flatness, surface roughness readings, and material certification — covering both the functional and cosmetic requirements of a visible stainless bracket.
New bracket programs can start with pilot quantities to validate fit and finish before committing to volume. Batch traceability and 24-hour quality response remain in place through the production life of the part.
