Abstract

Moulds are made by prefabricating a model from readily shaped materials, thermoforming a plastic sheet on to the model ot obtain an inverted copy of the model profile, and subsequently using the sheet to line a fluidised bed mould for casting finely divided concrete to obtain a replicate of the model durable enough for use as a tool for moulding plastics materials. The sheet is coated with a layer of releasing agent to remove the sheet from the cast mould. The process is suitable for making male, cavity or complementary mould tools. It is quicker and cheaper than machining original model from metal or other materials hard or heat resistant enough for use directly as moulding tools. Models can be adapted and modified tools cast from fresh thermoformings to develop tool shapes from faults on trial mouldings.
