Compression Moulding

Here the raw material urea formaldehyde is deposited in predetermined amounts automatically into the cavities. The Core and Cavity halves are engaged and curing commences. During the total cycle of approximately 2 minutes there is a brief withdrawal to release the accumulation of gases and then curing is completed before the cured mouldings are ejected. A finishing operation is required either by the wheelabrator – in the case of base moudings, rockers and some other moulding – and in the case of front plates cleaning of apertures and edge cleaning is undertaken as 2nd operations using deflashing tools on Holts Presses.
