Select the right type of mould is not only to save mould making cost, but also save moulding cost. What is more, only the optimum type of mould could meet your require.
Select the optimum type of mould
It is not only for mould purchase or product designer, even a mould sales. He maybe not clear well the different of Prototype mould, no-insert mould, or production mould, cold runner or hot runner mould, single cavity mould, multi-cavity mould or family mould, over mould or two-shot mould, insert mould or after machining, two plate mould or three plate mould etc..lded part.
There are some keys you should consider:
* Program life-Do you expect the program for the particular components to last one year? Five years? or longer? If you anticipate a long program life, then you need a mould that will be extremely durable to provide the most trouble-free moulding operation.
* Plastic material – What type of material will be used to mould the parts? This also weighs heavily on the type of mould material you will choose. For example, if the resin is abrasive, i.e. is a glass-filled material, metal-filled, etc., a softer mould material will mean greater wear on the cores and cavities, more maintenance and shorter life of the mould. Unfilled commodity-grade materials such as polypropylene, low-density polyethylene, and even unfilled engineering-grade materials such as polycarbonate or ABS, generally are okay for a softer grade of mould material.
* Number of parts required – How many parts will you require per month? per year? If that number is low – 100,000 parts or less annually – then you can probably get away with a softer mould material. However, if you require five million parts annually, you might want to look at hardened tool steels to meet these requirements.
