Manufacturers use a wide range of different molding techniques to create different components and products, including blow molding, compression molding, extrusion molding, and rotational molding. Injection molding is a popular, versatile, and cost-effective method for producing plastic goods. A heated liquid resin is injected into a mold at high speeds so it fills the entirety of the mold (including any crevices or complex shapes). There, it cools and cures into a hardened plastic form before being ejected for finishing, packaging, and shipping. This process can be used with high-volume and low-volume orders of goods varying in size and complexity.

A perfect, precision part begins with the mold. Building the tool takes time and a great deal of accuracy. It can also represent the largest investment in the manufacturing process, so getting it right is critical to the success of a project. If your goal is to manufacture parts with a high degree of precision in large volumes, the tooling becomes even more complex.
Plastic Injection Molding Explained
In manufacturing, molding refers to the process of shaping a type of pliable material or liquid by using a rigid matrix or mold. In plastic injection molding, raw polymer resin granules are melted into a liquid and injected into a mold, where the plastic takes the desired shape. Varying levels of heat and pressure may be applied to create the final profile for the end product.
One of the most common questions for those looking to source a plastic injection molder is “How much will a plastic injection mold cost?” It’s one of the most important questions since the actual mold represents the most significant expense in upfront production costs. That being said, many factors go into determining the full cost. With any custom injection molding project, your injection molder should be able to give you the final price tag. In this article, we will review the variables that can impact the cost so that you can be better informed when making a mold purchasing decision.
Injection molding presses allow manufacturers to produce a wide range of quality custom parts from high-performance resins. Depending on the press size and type, these advanced machines offer many different performance options and capabilities.
