Moulding
UMS utilise each or any category of moulding technology depending on the client's specific needs:
Sand Moulds
These moulds are generally used when large castings need to be made. They are formed using sand in combination with a binder. This binder may be clay and water (greensand) or a chemical (resin bonded).
Die Moulds
Dies can be used many times. The process has several advantages: a high degree of accuracy is reproducible over a large number of parts; parts have excellent surface finish; many parts can be produced in a short space of time.
Investment Moulds
This process uses ceramic shells formed around an expendable pattern. The benefits of investment moulds include their ability to produce precision engineered components with minimum wastage of materials and energy and subsequent machining directly from the poured metal. The process is very versatile, since the mould is formed from a single piece and there are no issues with draft angles and undercut. In addition to this, the surface finish of the component is excellent.
Metal Mould Injection
This process uses powder metal which is injected into a tool then sintered into the final shape. This process is very competitive for small parts and high volumes.
