Are your plastic parts consistently out of spec? Incorrect shrinkage calculations1 often cause these expensive problems. This leads to frustration, delays, and wasted material for product designers like Jacky. Mastering shrinkage involves understanding material behavior, using correct formulas for mold scaling, and applying practical compensation techniques during mold design2. This

Struggling with parts that don’t fit? Shrinkage often causes these headaches. Ignoring it leads to costly rework and scrap for everyone involved. Accurately calculating shrinkage involves using material data, empirical formulas, and sometimes software simulations. Compensating means designing the mold cavity larger than the final part, based on these calculations,

Misaligned molds lead to damaged equipment and defective parts. Choosing the wrong locating ring seems minor, but causes frustrating setup delays. Understanding locating ring standards1 prevents these costly headaches. Locating rings center the injection mold on the machine’s stationary platen. Standard sizes, primarily governed by suppliers like DME and HASCO,

Designing molds for tight tolerances1 is a real challenge. Get it wrong, and parts won’t fit, causing major assembly headaches and cost overruns. Let’s explore the critical requirements. Achieving tight tolerances in mold design demands precise core/cavity machining, a strong mold base, optimized cooling channels2, smart gate/vent placement, and choosing
