In the design process of structural plastic parts, should consider the factor of several aspects:
1.The performance characteristics of 1 plastic, such as physical mechanical properties, processing properties etc.
2.in the use of performance guarantee under the premise, structure and shape of plastic parts to simple, and conducive to the die flow, exhaust, feeding and high efficiency cooling hardening or rapid heating curing.
3.The overall structure of die, should make the mould parts are easy to manufacture, especially the complex degree of loose core and ejector mechanism. The rational design of the structure of plastic parts process is to ensure that the plastic parts meet the application requirements and comply with one of the key problems to meet the conditions of. The main content of the process design of plastic structure comprises a plastic part dimension and precision, surface roughness, shape, wall thickness, slope, reinforcement, bearing surface, fillet, hole, screw thread, gear, insert, hinge, mark, symbol and text.
