Design
Extensive expertise built up over more than thirty years, enables the best possible component design to be provided, using the latest draughting and solid modelling technology.
We can advise on details of component design, including the improvement and rationalisation of existing components.

Component design
Pro- engineer, Autocad Inventor.
Finishing
Painting, plating, polishing, shot blasting.
Cold chamber high pressure diecasting - Used for aluminium and its alloys which require a melting temperature too high for the hot chamber force pump mechanism to operate.
The metal is melted in a totally separate furnace and transferred by ladle into an extension tube (shot sleeve) leading to the mould tool.
From here it is forced into the die by a plunger.
Hot chamber high pressure diecasting - Used principally for casting components in zinc alloys with comparatively low melting points.
The metal is melted in a crucible (integral with the diecasting process) and injected into the mould chambers by a force pump mechanism, partially submerged in the molten zinc alloy through a hollow tube (the gooseneck)
Diecastings have a strength and rigidity unobtainable in
all but the most expensive engineering plastics. Thin
sections remain dimensionally stable with the minimum
of reinforcement; thick sections do not exhibit sink marks.
Quality and surface finish
Diecastings can provide the ideal combination of fine and
complex detail with good surface finish, suitable for
plating, painting or fine powder coating.
Cost effective
Diecasting provides a highly efficient component
production method giving excellent cost/performance
effectiveness for components - at both long and short
production runs.
The ability to mould to close tolerances (± 0.05mm, ±
0.002in), with complex features and thin sections
(1.5mm min.), with a good surface finish, can
substantially reduce time-costly machining and quality
control operations, minimise wastage.
