Learn how to choose a parting line that protects appearance, draft, shutoffs, ejection, slides, tolerances, tool cost and production maintenance.
Learn how to balance automotive plastic-part performance, cost and appearance through material, geometry, surface, tooling, process and validation decisions.
A practical design guide for overmolding and multi-material parts covering substrate, bonding, locks, shrinkage, gates, tooling, materials and validation.
Build a plastic-part prototyping plan using 3D printing, CNC, soft tooling, rapid tooling and production molds at the right development stage.
Diagnose ejector-pin marks on automotive molded parts by mapping defects, checking release force, cooling, packing, draft and the ejection support system.
Understand how resin shrinkage, stiffness, filler, friction, crystallinity, moisture and temperature change ejector force and pin-mark risk.
Diagnose ejector pin marks by mapping cavity location, release load, cooling, packing, pin support, timing, surface condition and part handling before correction.
Learn how ejector layout, stripper plates, sleeves, lifters, sequential ejection, sensors and release design reduce pin marks and distortion.
Diagnose ejector-pin marks by separating ejection force, part rigidity, pin layout, cooling, draft, packing, wear and processing causes.
A practical hierarchy for eliminating or reducing weld lines through geometry, gate strategy, material, temperature, venting, flow and validation.
