DFM
The first step of any project is always to conduct a comprehensive DFM investigation. When we start the DFM (Design for Manufacturing) process for an injection mold, we pay meticuluos attention to details, and take into account the obstacles our customer may face, as we aim to design a mold that meet all potential challenges head-on.

We consider DFM one of the most crucial aspects of the mold making process, as this process serves to improve the molding repeatability, enhance quality, minimize engineering changes and reduce costs further downstream in the manufacturing process.
