Plastic injection molding offers many benefits however when designing a part or a mold, there are some special considerations that need to be applied.  

At Crescent, our engineers utilize 2D and 3D computer generated files (Pro E, Autodesk, AutoCAD, & Work NC) to maintain the manufacturability of the parts to be injection molded or to create a mold design with the proper actions, gate locations, temperature control and venting. 

As a function of the part design process our engineers focus on the plastic component itself and make sure that the part meets the structural and design requirements for its use.   When focusing on the design of the part our engineers consider the draft so the part ejects properly from the mold, wall thicknesses to avoid sink marks, dimples or excessive shrinkage, and if necessary add ribs for improved strength and part features.

When looking at a mold design, our engineers see the aspects of the part that are important for injection molding purposes like thick or thin walls, draft, surface finish, materials and ultimately cost. 

By utilizing Sigma Soft Mold fill simulation software  we can get a computer aided 3D simulation of how the mold fills, packs and cools during the injection molding process before the part and mold are even built, helping to make critical decisions and often solving problems before manufacturing begins.

Because of the extensive years of injection molding and plastics tooling our engineers will analyze and consult with you on the most suitable material needed to provide the best injection molded product for your specifications.
