Selecting the Right Material for Injection Molds
Injection molds can be made from most polymers, including thermoplastics, thermosets, and elastomers. Since 1995, the total number of materials available has increased by about 750 percent. Materials today include alloys and previously developed blends. When selecting the material, two major criteria should be considered: strength and function. Cost also needs to be considered. Each material has its own specific parameters for moulding. Listed below are some tips for selecting the right material for your molds.
Injection molds are expensive. If you only plan to make a few parts, the cost of a mold for a million pieces may exceed your budget. For this reason, you should choose a mold that will produce high-quality small batches. In addition, you should choose a mold with the proper details, as an oversized mold will incur additional costs. Lastly, you should look for a mold manufacturer that is familiar with 3D printing. This can make the process easier and save you money.
