The mold is the key to building a perfect, precision part

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-volume, the tooling becomes even more complex.


Building a plastic injection molding tool

The Rodon Group fabricates the best tooling in the industry, and our tool warranty reinforces our claim. As long as Rodon is running a tool that we have built, there will never be any repair or maintenance charges. We design tools for high volume, high tolerance production for the life of your project. Our tools are constructed from stainless steel mold bases and cavities ensuring optimal mold performance and durability.

It’s all in the details

A quality precision mold, built to last for years is an investment in your company. Several variables impact the cost of a plastic injection mold including:

  • The core metal — High volume precision molds are made from hardened steel that can withstand the pressures of a long production run while still meeting close tolerances. At The Rodon Group, we have many stainless steel molds that have been in production for decades.
  • The number of cavities — We look to maximize cavitations in the mold to maintain the highest level of productivity. In general, we recommend creating one mold per part versus creating a family mold which tends to produce inferior products and has more downtime due to maintenance issues.
  • The mold base — The base holds all of the mold cavities, inserts and components together. The cost of the base is estimated based on the size of the mold and the type of steel used to make the base as well as the customization required.
  • Core/cavity machining — All molds must also be customized. Customization includes the placement of cores, cavities, ejectors, cooling lines, etc.
  • Part complexity — Just as the number of cavities plays a role in determining the cost of the mold, so does part complexity. This includes the surface finish of the final part as well as the number of undercuts required. Turnkey or vertically integrated injection molders

The combined effort of our designers and toolmakers results in molds that ensure quality, precision tolerances, and optimized cycle times. We have the capacity to mold parts with complex geometries and variations in wall thickness. Our maximum part size is 10” square, although our primary concentration revolves around parts with even smaller dimensions.
