Injection mold building  now requires a combination of technology, equipment and highly skilled mold builders to produce injection molds faster with an almost limitless geometry for the plastic components.    

Our journeyman mold builders produce injection molds that provide cavity-to-cavity consistency and repeatability by ensuring molds are built with proper runner sizes, gates, cores and actions.    Our capabilities extend from single cavity to 96 cavities and follow the SPI 101-103 mold classifications. 

Our configurations include:

  • MUD (Master Unit Die)  – great for smaller and simpler part designs that requires side actions to form features
  • Unscrewing Molds – used when there is a requirement for male or female threads on a plastic component

  • Action Molds – have some sort of mechanical action incorporated into the design when a hole, slot, undercut or thread is needed that is not perpendicular to the parting line

  • Two Plate Molds – provides one parting line and the mold splits into two halves, the sprue, runners, gates and cavities are all on the same side of the mold

  • Three Plate Molds – is a mold which has a runner plate in between the moving half and a fixed half, these molds will have two parting lines and are used because of their flexibility in gating location

  • Hot Runner System – is an assembly of heated components used to inject molten plastic into the cavities of the mold, these are typically more expensive to manufacture and run but allow for savings by reducing plastic waste and reducing cycle times

Crescent Industries also provides a cost saving solution for new tooling projects.   We have invested in an extensive inventory of master mold bases.  These frames are injection molds that have interchangeable inserts which allow for quicker and less expensive mold designs.  We make these mold frames available to house your unit molds and tool sets when your molded product is compatible with this type of tooling.  This saves you thousands of dollars in tooling costs.  

Since we have an on-site tooling facility, we perform mold maintenance, repair and revisions to help our customers, click here to learn more.
