Aluminium Vacuum Die

APL have been developing vacuum casting technology over the last 8 years. The process can be used for both aluminium and zinc based alloys.

Vacuum assisted pressure diecasting enables the production of technically challenging components with low reject rates and sometimes the production of components that would otherwise be impossible with conventional pressure diecasting techniques.

Specific benefits of Vacuum Assisted high pressure diecasting:-

Components requiring good internal soundness such as oil pump bodies, pneumatic valves and gas control components.

Components that require a good surface finish such as decorative items.

Components that are intricate such as heat sinks with deep webs and bosses.

Components in zinc alloy that are subsequently subjected to a hot process such as plating and over bake painting, where blistering would normally be a problem.

We have now installed the vacuum technology on to our full range of diecasting machines so that components of all sizes can benefit from this advancement.

We would recommend that customers contact us at an early stage of their component design, as we may well be able to incorporate features into the component not normally thought possible, that would reduce subsequent assembly operations and reduce the quantity of components required in an assembly.
