Die Casting

Aluminium casting

The foundry is fitted out with 15 high-quality die-casting machines with closing forces ranging from 250 to 1,000 tonnes. Fourteen of these machines are equipped with Shot Control Technology, which allows demanding products to be manufactured reliably with a high degree of repeatability.

The Perfect Fit™ principle ensures that the die-castings are produced to exacting tolerances in the mould, thus avoiding the extra costs of a possible machining operation.

In addition to the conventional die-casting method, we also offer vacuum die-casting. This method is an effective solution for special applications where porosity must be kept to an absolute minimum. We are also able to weld vacuum die-cast products or heat-treat them in order to attain specific properties.

Buvo is capable of producing various volumes and product weights. The volumes vary from 5,000 to more than 5,000,000 items per year with a product weight of between 10 grammes and 10 kilogrammes. This capability means that Buvo is able to service the needs of differing industries such as the automobile, gas, office equipment, telecom and medical industries.

Buvo also uses different alloys in order to satisfy the requirements of different applications. The most commonly used materials are 226 (GDAISi9Cu3) and 230 (GDAISi12). Buvo has melting ovens for both materials, from which the die-casting machines are fed. The available options are considered on a case-by-case basis if an application requires a different material. Please refer to the materials overview for an overview of all the alloys that can be used.
