The Rodon Group expands facility to now include custom, large part plastic injection molding capabilities.
As plastic injection molding methods continue to advance and evolve, allowing for enhanced flexibility and more sophisticated customization options, molding companies must be able to stay ahead of the curve in order to offer clients the latest technologies and highest-quality end products that suit their needs in the changing market.
Plastic injection molding has a language all its own, and with hundreds of unique terms, it can be difficult to learn the language. To help, we put together a list of the 15 more commonly used terms to know when discussing plastic injection molding, mold parts, machinery, materials, and problems. We hope you find this to be a useful resource.
Injection Molding Terms:
Resin is the raw material used to create the finished part in the plastic injection molding process. With hundreds of commodity and engineering resins available on today’s market, the material selection process for plastic injection molding may seem daunting at first, so research your options carefully, and consult with an experienced plastic injection molder to help determine the ideal choice.
Design engineers have various options when choosing a plastic injection molding process to best suit their specific application. Each of the three primary methods — hydraulic, electric, and hybrid — feature unique benefits and drawbacks. To make the right selection for your project, it’s important to have a full understanding of how these methods differ and what they can offer you.
Ever since its introduction in the late 19th century, plastic injection molding has revolutionized the way we create plastic products. Although the technology has evolved significantly over the years, many injection molds today still fall into two main categories: hot runner and cold runner systems. Each of these systems has their own benefits and limitations which make them better suited for specific applications.
Understanding the differences between these technologies can help you have a more productive and informed discussion with your plastic injection specialist to determine the most feasible option for your unique application.
When engineering the wall thickness of a plastic part, a careful balance of weight, geometry, and budgetary considerations must be maintained. For example, while thick plastic walls offer more strength, they also have a greater tendency to warp during the cooling stage of the manufacturing process.
As plastic injection molding methods continue to advance and evolve, allowing for enhanced flexibility and more sophisticated customization options, molding companies must be able to stay ahead of the curve in order to offer clients the latest technologies and highest-quality end products.
The success and precision of a part depends on the quality of its mold, but building a reliable, long-lasting tool can take a considerable amount of time — and requires a great deal of accuracy. Also, molds are often one the largest capital investments in a project, so it’s critical that tooling is built right the first time around. This is particularly important in high-volume injection molding projects, where molds can be extremely complex.
With the use of injection molding presses and high-performance resins, plastic injection molders are able to craft a broad range of quality custom parts. Just as all resins are unique, these sophisticated machines offer varied capabilities and performance options depending on press size and type.
