Injection Molding is a manufacturing process for producing parts in large volume. It is most typically used in mass-production processes, where the same part is being created thousands or millions of times.
Plastic Injection Molding Materials : There are many varieties of materials that will be utilized in the injection molding process. Most polymers are all thermoplastics, some thermosets and a few elastomers.
Each material needs a different set of processing parameters within the injection molding process. As well as the injection temperature, injection pressure, mold temperature, ejection temperature and cycle time.
A comparison of commonly used materials : Injection Molding Materials
Plastic Injection Molding Process : Plastic injection molding is out and away the foremost common thanks to manufacture large volumes of finished plastic elements for each reasonably commercial and industrial use. One cycle to make a finished part may take anywhere from a couple of seconds to minutes depending on part quality and size.
We’ve got provided a detailed breakdown of the process : Injection Molding Process
Plastic Injection Molding Tolerances : All plastic material will expand and contract under the influence of heat and moisture. Our tolerance guide will give more general information on the characteristics of most common resin types for typical part features.
We will work closely with you to optimize your designs for manufacturing. We will indicate any areas where poor design may produce thermal stress, shrinkage, warping, etc….
Plastic injection molding is the preferred process for manufacturing plastic parts. Injection molding is used to create many things such as electronic housings, containers, bottle caps, automotive interiors, combs, and most other plastic products available today. It is ideal for producing high volumes of plastic parts due to the fact that several parts can be produced in each cycle by using multi-cavity injection molds.
Some advantages of injection molding are high tolerance precision, repeatability, large material selection, low labor cost, minimal scrap losses, and little need to finish parts after molding.
Some disadvantages of this process are expensive upfront tooling investment and process limitations.
