De-energising heat treatment
Most engineering plastics semi-finished products (rods, plates, tubes) are heat treated - stress relieved - during their manufacture to achieve the highest possible dimensional accuracy and working load capacity. The completion of extrusion, casting and pressing by heat treatment does not, of course, mean that the semi-finished product is completely stress-free, but is the result of a technological and economic optimisation of the production process. Experience has shown that machining [...]
Machining of plastics
Machining of plastics is usually necessary when the number of pieces to be produced is so small that traditional plastic processing methods (e.g. injection moulding) are not economical due to their high tooling costs, or when they cannot achieve the required precision or complexity. A common mistake in the machining of plastic products is to try to use the same rules and solutions as for metals without modification, ignoring the [...]
