Injection Molding Geometric / Geometry Possibilities
The most commonly used plastic molding process, injection molding, is used to create a large variety of products with different shapes and sizes. Most importantly, they can create products 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 and keep your product between 2 to 20 inches.
The size of a 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.
