At Molding Dynamics, precision starts long before plastic hits the press. It begins with how we help engineer and validate your plastic mold. From part review and prototyping to moldflow analysis and press compatibility, we bring decades of experience and high-performance equipment to every step of the process.
While we don’t fabricate molds in-house, we work closely with trusted tooling partners to turn our engineering insights into high-quality plastic molds that deliver consistent performance.
Not all plastic molds are created equal. The quality of your plastic mold sets the stage for every downstream decision—affecting everything from part tolerances and cycle times to scrap rates and tool lifespan.
We guide every mold development project with a focus on:
We take a hands-on role in every mold project by combining engineering support, part testing, and data-driven validation.
We collaborate with your team to review CAD files, identify undercuts, evaluate tolerances, and improve moldability from the start.
Before steel is cut, we simulate plastic flow, gate placement, venting, and shrinkage to reduce warping, sink marks, and other costly issues.
Need to test fit and function before full production? We create prototype tooling to validate part geometry, material performance, and critical dimensions.
Once the prototype is approved, we work with our mold-making partners to turn the validated design into a robust, production-ready tool.
Our in-house capabilities include both vertical and horizontal molding equipment ranging from 75 to 700 tons. This allows us to build and test molds for a wide range of part sizes and materials.
Used for more compact molds and complex insert applications, our vertical presses ensure tight tolerances and controlled resin flow.
With over a dozen presses ranging from 85 to 700 tons, we support everything from small precision parts to large structural components.
Our equipment specs include wide tie bar spacing, large mold thicknesses, and varying shot sizes to match part volume and complexity.
Having the right press size takes capacity and your part’s requirements under consideration, ensuring the right tooling, shot size, and tonnage.
Our equipment enables:
We build molds and keep them running at peak performance. Every plastic mold in our care goes through:
We track all tooling to ensure your molds are ready when you need them.
