Liquid Rubbers in Inserted Parts Technology

The two alternative concepts for the production of composite products are the thermoplast machine and the LR machine. The prerequisite for a successful product is the choice of suitable materials. The advantages of using the LR machine are  

The main disadvantage is investment cost and that the machine occupies a large space. 

As mentioned earlier, the insert parts can be produced by any apparatus. This can be extmsion with subsequent cutting, injection moulding, two or multiple colour (also two or multiple component) injection moulding, press moulding, punched and bent metal sheets, cast iron, sintered metal, ceramics in any shape, cut glass, etc., or moulded or extruded silicone rubber (as in catheters and insulators). 

Another very important property is the thermal stability of the insert. The processor never faces problems using steel or other metals, as their thermal stability is determined by their melting point. However, phase transitions in the plastic or metallic part, e.g., from one crystal structure to another might be dangerous for the subsequent performance 

For glass or ceramics, brittleness and eventual consequences of thermal shock treatment
