New Mold Creation Process
It’s exciting to have a new mold or tool created. We here at The Toolroom love creating new molds and tools. If you have a mold or a tool you want to have created, here are the steps we take in the process to create a new mold or part.

  1. You send us a 3D CAD model of the molded part you want a mold or tool for, along with the requirements for the mold such as annual volume, steel requirements, the number of cavities the mold or tool will have, and any other requirements. Requirements vary from mold to mold and tool to tool, so please contact us to find out what other requirements we would need from you to create your new mold or tool.
  2. Next we provide you with a quote. Once the order is placed, we begin work on the design and will create a 3D CAD model to ensure the design of the tool is correct in meeting your requirements.
  3. Since we want to ensure a quality experience each step of the way, we usually hold one or two design reviews with you to ensure the mold or tool design meets your expectations and requirements.
  4. As soon as you approve of the design, we begin an iterative process of manufacturing the mold or tool. Depending on your preference, the mold is built.
  5. Once the mold build is completed, the mold is sampled or trialed, which means we mold a few parts. Essentially, we take the mold for a trial run.
  6. During the first trial run, the mechanics of the mold are verified. At the same time, we inspect and measure the parts from the first sampling and compare it to your part dimensional requirements to make sure the part is correct. If we find issues with the mold mechanics or part dimensionals, we fix them and run a second sampling or trial. We continue this iterative process as many times as necessary to get the mold correct.

We strive for quality work and customer satisfaction so during or after the samplings and trials, we invite you to our shop to approve the mold in person.
