Big Bear specialise in moulding medium to large size plastic components in single sheet and twin sheet, using vacuum forming and pressure forming technology.

Big Bear operate 5 large rotary moulding machines with the unique capability to mould parts up to 3.5m x 2.5m.

Big Bear also operate 9x5 axis CNC trimming machines. All parts are trimmed on purpose-built jigs and fixtures.

What is thermoforming?

The process involves heating a plastic sheet until malleable and then applying it over a mould. A vacuum can then be applied to “suck” the sheet onto the mould to make the part. The part is then separated from the mould, and the excess material trimmed off.
