What is 3 plates plastic mould? The three-plate mould differs from the more common two-plate design format in terms of utilizing more than one split or parting line. The tool construction is divided into three distinct plate build-ups which separate…
procedures for developing a new plastic product Below we list a fairly standard sequence of steps that you will probably have to go through in the course of designing and making a new product You can use it as a…
The mould impression Often incorrectly referred to by some engineers as the cavity，the mould impression is a hollow area contained inside the mould into which molten polymer is injected and allowed to cool. When a mould tool contains more than…
How to identify Faults in injection molding A logical and systematic method of dealing with faults is most desirable, and many practical moulders have their own scheme of operation. In compiling such a scheme, it is important to ensure that…
Injection molding allows mass production of precision plastic parts once the initial molds are made. But successfully navigating this intricate process requires understanding its nuances. This 10-step guide breaks complex mold design into simple, logical stages for flawless execution. 1.…
Optimising time cycle and machine productive time Whatever ideas for cost saving are introduced into the injection moulding of plastic components，ultimately the time cycle of the machine and the rate at which it can be made to produce good saleable…
Cost saving methods The financing and costing of projects take the greatest contribution to profitability. There are，however，some other methods by which cost savings may be achieved. These include rationalisation of material stocks and grades, utilisation of standard material，and the use…
Fixed and variable costs The main fixed cost of the injection moulding process is，of course，the capital cost of the equipment, but other fixed costs—rent of property，rates，etc.— must not be lost sight of. In the world of the entrepreneur—and such people…

Warping Mouldings warping after removal from the mould are very common and are always the result of frozen-in stress; differential shrinkage or，with filled materials，filler orientation. This is nearly always a processing problem，but it can also be caused by a machine…
