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.
Since our founding in 1956, The Rodon Group has crafted billions of high-quality plastic components for all types of applications, earning us a reputation as one of the industry’s best high-volume injection molding providers for both standard parts and complex custom projects.
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.
While plastic injection molding may not be rocket science, it is still a very complex manufacturing process. It involves great attention to detail and there are many factors to take into consideration.
First, the part design must be developed and maximized for manufacturability. Then a mold must be built. This involves computerized as well as hand tooling. The mold must then be tested along with resin and color options to determine the best formulation for the project.
Used in all types of industries, plastics provide versatility and strength across a wide range of applications, from automotive body parts to human body parts. Each application requires a special manufacturing process that can mold the part based on specifications.
With patient lives and staff safety at stake, the medical and pharmaceutical industries require adherence to strict safety and quality standards. Medical and pharmaceutical parts must be able to meet stringent quality and traceability standards, and all steps of the manufacturing process must be carefully monitored. In these sensitive industries, liability is essential.
To ensure consumer health and safety, the food and beverage industry must adhere to stringent specifications— requiring nontoxic parts, BPA-free components, and FDA certification. For plastic injection molding in these food service applications, various food grade materials must be used.
How often do you source a plastic injection molder? If you are like most companies and purchasing managers, probably not very often. Typically, once you have selected an injection molder to work with, you are likely to stay with them for a long time as long as they keep producing quality plastic parts.
