Precision aluminium casting

Alloy is our passion

The method of plaster mould casting is technology which enables the casting of complex components (makes it possible to cast thinner cross-sections) which would be, in terms of conventional processing, extremely difficult and too expensive. The advantages of our casts are their accuracy and uniform quality which leads to reduction of the cost on post-production. The technology is suitable for single parts or however the series production is the most effective. Another advantage is a short response time of technical preparation of production. “In other words, we can begin the production of your part within days after the first call.”

The methods of aluminium precision casting were developed in the USA, from where it was imported to Sweden in the 1950s. Aluminium cast in plaster moulds formed on solid patterns, Solid Plaster Mould-SPM, and aluminium cast in ceramic moulds on lost wax patterns (Investment) are called Precision Castings. Precision Castings essentially have the same properties as high pressure die cast aluminium in terms of surface finish and precision but can be produced in smaller volumes, 5 – 1000 pcs/year, at a lower total cost.
The method of plaster mould casting is similar to sand mould casting but gives better surfaces and makes it possible to cast thinner crossections. Investment casting is based on pre-cast wax patterns that are embedded into ceramic forms and subsequently burned out before the form is being filled with molten aluminium, this method is suitable for castings with intricate geometries.
The two methods give greater freedom of design than what is possible with the high pressure die casting method. The components can, for example, be undercut and have zero draft. Precision Castings are suitable for lightweight designs, since cross sections as thin as 0.8 mm can be cast and heat treated. Plaster mould casting, according to the SPM-method, is best suitable for somewhat larger castings, 1 to 50 kg, in series from 5 to 500 pcs/year. Investment casting is ideal for smaller and more intricate castings with weights between 100 g and 3 kg and series up to 1000 pcs/year.

All you need to know …

We are ready to deliver the casts up to 20 kg of weight.
Our casts have normally surface roughness from 1,6 to 3,2. The structure of the casting is fine-grained and homogeneous, with minimal porosity. Castings exhibit great mechanical properties up to 400 MPa.

Despite the fact that subsequent machining is minimised, we offer these services to our customers in our sister’s branch Eurozet – Metal Working. We offer many kinds of finishes. Tell us what you need!
