About Metallgießerei Wilhelm Funke
The metal foundry Metallgießerei Wilhelm Funke GmbH & Co. KG was founded in 1960 as a pure aluminium foundry in Alfeld (Leine) and today produces, with around 100 employees, individual parts, small series and prototypes in aluminium, magnesium, heavy metal, grey and spheroidal cast iron as well as permanent mold castings. The range of processes includes sand casting, permanent mold casting and counter-pressure casting; in addition, artistic casting projects and castings for art objects are realized. In the company's own pattern-making shop, production patterns are made from wood, plastic and metal, along with CAD design, molds, jigs and fixtures, rapid prototyping and reverse engineering. Machining is carried out on eight 5-axis machining centers, supplemented by laser welding and optical measurement. The company's castings are used, among other things, in high-end sports cars and prototype vehicles; further customers come from aerospace and mechanical engineering. Production capacity is approximately 350 tonnes of castings per year.

Materials and Casting Processes
Aluminium
Light metal for sand, permanent mold and counter-pressure casting, e.g. for automotive and prototypes.
Magnesium
Lightest engineering material in the foundry's range, processed in sand and permanent mold casting.
Grey cast iron (EN-GJL)
Material produced by the sand casting process for mechanical engineering components.
Spheroidal cast iron (EN-GJS)
Ductile cast iron for higher-loaded castings produced by the sand casting process.
Heavy metal
Alloys produced by sand casting for applications with higher density requirements.
Sand casting
Flexible process for individual parts, small series and prototypes in aluminium, magnesium, grey and spheroidal cast iron.
Permanent mold casting
Permanent mold process for aluminium and magnesium castings with reproducible quality.
Counter-pressure casting
Casting process for dense, fine-structured lightweight metal components.
Rapid prototyping
Fast sample production as a manufacturing alternative before series production begins.
CNC machining
Mechanical final machining of castings on 5-axis machining centers.
Laser welding
Repair and joining work on castings and patterns.
Production pattern making
Foundry patterns in wood, plastic and metal, including molds, jigs and fixtures.
