AllTech has strong offshore capabilities for manufacturing. This unique outlet opens the door to a range of specialty services typically only enjoyed by larger OEMs. This includes a shareholder foundry located in China that can pour an array of both ferrous and non-ferrous alloys with quality and intricacy.

BENEFITS:

The benefits of casting can be an efficient alternative for complex components which would otherwise require extensive machining, weld time, or material waste. The cast alternative is a stronger, simplified component. The production is more efficient; higher volumes produced in less time with less material waste. Above all, the cost reduction can be the ultimate renovation to the component.

STRENGTH & APPLICATION:

The strength and durability of steel, iron, and other ferrous alloy castings makes them ideal for wear applications when components are exposed to significant abrasion, harsh environments or heavy impact. For example, equipment used in industries such as mining, earth moving, or forestry utilize many cast steel parts for excavation, aggregate crushing, and mineral processing. These examples are only a snapshot of the broad spectrum of where castings can be utilized.

In collaboration with our foundries and clients we analyze every part for the highest quality process and production efficiency. Take a moment to learn more about the casting processes we offer and the parts we have produced utilizing following casting processes.

  • Lost Wax & Investment Casting

    Lost wax casting can produce an as-cast surface finish of near-net-shape that often requires little to no secondary machining. The final component also has a cleaner surface finish than what is achievable through typical processes such as sand casting. Lost wax casting is suitable for components up to roughly 200 lbs.

    Like lost wax casting, yet the investment casting process can achieve even higher quality surface finish. Investment casting utilizes a finer sand and higher quality wax for the mold and pattern development. Typically investment castings is best for components up to 50 lbs.

    Each of these processes is most suitable for steel grade castings.

  • Lost Foam Casting

    More common with ductile, grey and cast iron material grades, lost foam casting is when styrofoam granules are compressed to produce a foam replica pattern. This foam pattern is coated with a molten sand and ceramic coating. When this coating has cooled and formed around the pattern, hot metal is poured in and the styrofoam pattern will be melted away. As with lost wax casting this process is ideal for parts ranging up to roughly 200 lbs.

  • Sand Casting

    Sand casting is a versatile process that can pour steel & iron grade parts in virtually all size and weight ranges from 1lb up to large multi-ton components.

  • Pressure Die Casting

    Pressure Die casting is a molding process in which molten metal is injected under high pressure and velocity into a split mold die. The split mold used under his type of casting is reusable. Die casting is categorized two types namely – hot chamber and cold chamber. Metals like Zinc, tin and lead alloys are cast in hot chamber die casting having melting point below 3900 C. Whereas aluminum alloys are casted in cold chamber die casting machine. Aluminum dissolves ferrous parts in the die chamber and hence preferred to be used in cold chamber die casting.

  • Materials
