| Triton Global Sources has partnered with
many offshore casting manufacturers or foundries of different disciplines,
mostly in China, to offer a full complement of casting processes. These include: |
- Sand casting
The lowest cost method for making bulk parts which do not require tight tolerances. Applications include bases, housings, and brackets. More precise dimensions can be achieved by a secondary machining operation.
- Permanent mold casting
Similar to sand casting in principle, this method employs a hard mold instead of a porous sand mold. With only a slightly higher mold cost than sand casting, this process achieves superior tolerances and surface finishes.
- Investment casting
This precision casting method can provide a fine surface finish with a tolerance up to +/-0.005". The method uses heat-disposable wax or plastic patterns, which are surrounded by refractory material, to form a monolithic mold. Patterns are removed from the mold in ovens and molten metal is poured into the hot mold. After cooling, the mold material is quite fragile and must be carefully removed from the castings. The castings represent exact duplicates of the patterns. Following a light grinding, buffing, or other secondary finishing operation, the castings are inspected and shipped to the customer.
- Die casting
Die casting is also called pressurized casting. Melted metal is pumped into a cavity using pressure. The pressure gives the finished part a more homogeneous microstructure, a better surface finish and more precise dimensions. Because of the high pressure, highly intricate structures can be achieved with zero or minor secondary machining. For high volume parts, die casting can produce huge cost savings.
- Cast Materials
Gray iron, ductile iron, carbon steel, alloy steel, stainless steel, aluminum, brass,
bronze, zinc and other ferrous and non-ferrous metals.
