Short-lead-time process for small-part micromolding is launched. A process suited for part sizes of 0.33 to 1.31 oz in medium to large quantities can cut lead time to market by half, according to the molder. The Micro-Cell micromolding process, developed by PTI Engineering Plastics Inc. (Clinton Township, MI; 586/263-5100), uses a closed-loop system to convey raw material to molding machines by way of a material-handling machine.

The Micro-Cell micromolding process, developed by PTI Engineering Plastics Inc. (Clinton Township, MI; 586/263-5100), uses a closed-loop system to convey raw material to molding machines by way of a material-handling machine. Mold changes are performed in less than 10 minutes; part runners and residual regrind are nonexistent. Optimal cavitation calculated at 60–75% utilization per job reduces downtime, and few mold cavities are needed due to the size of the Micro-Cell machine, producing lower defect rates. Like conventional runnerless molds, Micro-Cell molds are built with updated CAD/CAM/CNC equipment. PTI offers in-house tooling, standard mold bases, and unit mold frames to reduce tooling costs.
