Vacuum Casting

Vacuum casting can save clients a great deal of time during the product development process and could prevent costly production tooling.

The master model is replicated by making a silicone mould to create small or large quantities of cast parts. Polyurethane resins are used to simulate the products final manufacture material.

ABS, Polypropylene, Polycarbonate, PMMA, Glass filled Nylon and Rubber with various Shore hardness can all be closely resembled. Silicone seals and gaskets can also be moulded.

AG Prototypes uses PU pigments and inks to match colours to their customer's specifications, so castings will be an accurate representation of the final product in material, surface finish and colour.

Parts can also be replicated in UV stable, water clear resin or rubber and coloured tints if required. Pearlescent and metallic powders and glitters can be added to create spectacular finishes and effects.

Flexible rubber parts can be produced from rigid prototypes using vacuum casting techniques.

These prototypes can be produced in clear or matched to a specific colour reference and with PU rubber ranging from 25A  to 90A Shore Hardness.

Silicone parts can also be created and to FDA approval if required.

This process is ideal for gaskets, seals, rubber keypads, soft-feel surfaces and rubber over- mouldings.

The casting process involves placing the heated mould and resin components into the vacuum casting machine. The resin is mixed and poured, under vacuum, and gravity fed into the mould.

The mould is placed in an oven and once the cast part is fully cured, the part is removed from the mould and carefully hand finished, to remove the vents and gates.
