Mold Design · Engineering GuideMost “mold design” articles are really part design articles. Wall thickness, ribs, draft. That’s useful, and we cover it on our plastic part design page.This one is about the tool itself. The steel. Where the plastic…

PC Mold DesignPC Runner and Gate Design That Stops Splay, Cold Slugs and CrackingMost polycarbonate defects are designed into the tool, not created at the press. PC runner and gate design decides whether a clear part shows splay, cold slugs…

Learning CenterInjection molding, 26 topicsMost molding questions come back to the same handful of numbers. How thick the wall should be. How much draft before the part drags on the core. Why a quote doubled after somebody added one snap…

Robotics & AI HardwareEMI/RFI Shielding & ESD Plastics: Conductive Injection MoldingPlastic is transparent to electromagnetic radiation. To shield electronics or dissipate static in a molded part, the resin has to be made conductive — with the right filler and the…

Robotics & AI HardwareHigh-Precision Connector Molding for AI HardwareAI compute runs on high-speed connectors. Their insulators are injection molded in LCP at tolerances measured in microns, because at 224 Gb/s the plastic itself shapes the signal.This guide covers the resin…

Robotics & AI HardwareData Center Plastic Parts: Chassis, Cooling & Cable ManagementAI demand is pulling plastic into the server rack. A molded part carries airflow geometry, mounting features, and clips in one piece — an assembly of sheet metal cannot.This…

Robotics & AI HardwareRobot Plastic Material Selection GuideMost robot part failures trace back to the wrong resin, not bad molding. Pick by continuous temperature, load, moisture, and cost — in that order — and the part lasts.This guide gives a…

Robotics & AI HardwareInsert Molding for Robotics: Metal Where You Need It, Plastic Everywhere ElseInsert molding places a metal part into the mold, then encapsulates it in plastic in one shot. The robot part comes out with metal threads, bearings,…
