Alumess specialises in the casting of high-quality products made of aluminium, stainless steel, steel and iron. The material to be selected depends on the application and the quantities. You can always rely on our professional advice!
High-pressure casting is also called injection moulding. This casting method is the most used method worldwide for light metal alloys such as aluminium, magnesium and Zamak. The majority of our casting products are manufactured using high-pressure injection moulding technology.
With high-pressure injection moulding, the highest tolerances for metal castings combined with high surface quality can be achieved. Our foundry in China has a very high level of automation in high-pressure injection moulding, meaning that we organise this production process very efficiently. We use high-pressure injection moulding machines from 80 to 2,000 tonnes of closing pressure and can create products from a few grammes in weight up to about 10 kilos by injection moulding.
Injection moulding is especially suitable starting from batch sizes of 2,500 up to several million units.
The low-pressure casting method is a semi-automatic process in which molten aluminium is poured into the mould in an increasing and controlled manner.
During the process, we keep a close eye on the filling speed and temperature. This working method creates the best possible structural properties with the minimum level of porosity.
Low-pressure casting is especially suitable for heavier structural components.
This casting method is particularly suitable for very high quality requirements, as in the case of gearboxes, structural parts and other components that are loaded under strength.
Low-pressure casting is suitable for small series, from a few hundred up to the mass production of hundreds of thousands of units.
All production methods are organised very economically at our foundry in China. For example, our injection moulding machines are fully automated and advanced robots ensure a more efficient casting process to minimise the use of manpower.
Diecasting is a technology in which molten aluminium is poured into a steel mould. The major advantage of this casting method is the investment price of the tools.
In terms of investment, diecasting is cheaper than injection moulding and, in process terms, cheaper than sand casting. In addition, the surface quality is higher than for sand casting but lower than for high-pressure casting.
Diecasting is usually selected for smaller series of for strength-loaded parts that can undergo or receive heat treatment.
Diecasting lends itself to series from several hundred up to several hundred thousand units.
Sand casting is generally used for smaller quantities. Alumess only supplies hand mould sand casting, generally for larger and heavier parts.
We can accommodate sizes up to 2.5 metres in length and weights up to 50 kg.
If somewhat less accurate tolerances are permitted in your product, sand casting is an excellent production process. Sand-cast objects are found in the decorative market, but technical products such as bearing blocks, impellers and housings are also made using sand casting technology.
