The most commonly used plastic molding process, injection molding, is used to create a large variety of injection molds with different shapes and sizes. Most importantly, this molding method can create injection molded parts with complex geometry that many other processes cannot. There are a few precautions when designing something that will be made using this process to reduce the risk of weak spots. First, streamline your product or keep the thickness relatively uniform. Second, try not cramming too many details into one part may cause visual defects in show surfaces or the inability to fill some of the details without sacrificing others. It may be better to make multiple injection molds for your process. A good injection molding company can steer you in the right direction.
The size of an injection molded part will depend on a number of factors (material, wall thickness, shape, process etc). The initial raw material required may be measured in the form of granules, pellets or powders. Here are some ranges of the sizes.
