For various reasons, injection molding is known to be the best method of making polycarbonate components. One of them is that it allows the production of precise and detailed parts which are important especially in electronic and automotive industries. Moreover, this process is highly efficient as large numbers of parts can be produced uniformly with minimal wastage.

It’s essential, first and foremost, to choose a starting point for injection pressure that will be sufficiently high for completely filling a mould cavity. The data shows that it is advisable to start with a pressure of roughly seventy megapascals and then adjust depending on part quality and fill time. A low pressure can result in incomplete filling or short shots whereas excessive flash or stresses may occur if the pressure is too high.

Once filled, the mold should have a holding pressure between thirty megapascals and seventy megapascals so as to compensate for material shrinkage when it cools down and solidifies. This holding pressure need not exceed the initial injection pressur.

Consistency: Whether producing one part or one million, precision injection molding maintains consistency. Each piece is virtually identical, free from defects, and meets stringent quality standards.
