About Ray Chan
Ray Chan works with buyers and engineers across the automotive, medical, electronics and consumer goods supply chains β from the first DFM conversation and tooling quote through high-volume production ramp-ups at DieStrike.
He has spent his career around precision injection molding and high-speed stamping: cavity steel held to Β±0.002 mm on critical features, mirror finishes at Ra 0.02 Β΅m, and the sourcing decisions that separate smooth programs from costly rework. He writes to share that engineering and sourcing know-how β no fluff, just the numbers and decisions that actually matter on the shop floor and at the negotiation table.
"The best mold program is the one you never have to fix β good DFM and honest sourcing decisions up front save months and money later."
