Casting by material, precision CNC machining, plus heat treatment and surface finishing support services. OEM/ODM — equally reliable for small multi-variety batches and standardized high-volume orders.
Silica sol investment casting: 3g – 130kg per piece, surface finish to Ra 6.3, as-cast tolerances ±0.10mm.
Popular grades: 304 / 304L / 316 / 316L / 410 / 416 / 2205 / 17-4PH. Built-in chromium oxide layer gives exceptional anti-corrosive properties — ideal for military, medical, marine, food and petrochemical applications.
High strength with excellent machinability — gear boxes, bearing boxes, valve parts and pump components at competitive cost.
Duplex steel, heat-resistant steel, alloy cast steel and nickel-based alloys for demanding wear, corrosion and high-temperature conditions.
The lightweight option for weight-sensitive machinery and equipment components, with anodizing and other finishes available.
| Grade | Characteristics | Typical Industries |
|---|---|---|
| 304 / 304L | Food-grade steel; standard for cleanliness & corrosion resistance | Food & Dairy · Medical · Mining · Petrochemical |
| 316 / 316L | Superior corrosion resistance incl. marine environments (L = low carbon) | Automotive · Petrochemical · Food & Dairy |
| 410 / 416 | 400 series: high strength, machinable; break rather than bend under pressure | Automotive · Machine Tool · Food & Dairy |
| 17-4PH | Strongest of the stainless family — for parts that cannot bend | Military · Medical · Machine Tool |
| 2205 | Duplex stainless: strength plus corrosion resistance | Petrochemical · Marine Engineering |
Tired of purchasing raw castings, sending them out for secondary machining, bringing them back for inspection, then re-sending for heat treat or coating? QDOS eliminates this tedious exercise — one-stop, turn-key products ready for assembly.
From casting blank to assembly-ready product, one partner is responsible all the way.
