Select the right type of mold is not only to save mold making cost, but also save molding cost. What is more, only the optimum type of mold could meet your require.
Select the optimum type of mold
It is not only for mold purchase or product designer, even a mold sales. He maybe not clear well the different of Prototype mold, no-insert mold, or production mold, cold runner or hot runner mold, single cavity mold, multi-cavity mold or family mold, over mold or two-shot mold, insert mold or after machining, two plate mold or three plate mold 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 mold that will be extremely durable to provide the most trouble-free molding operation.
* Plastic material – What type of material will be used to mold the parts? This also weighs heavily on the type of mold material you will choose. For example, if the resin is abrasive, i.e. is a glass-filled material, metal-filled, etc., a softer mold material will mean greater wear on the cores and cavities, more maintenance and shorter life of the mold. 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 mold 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 mold material. However, if you require five million parts annually, you might want to look at hardened tool steels to meet these requirements.
