Ray Chan

Ray Chan runs MOLDITQUICK, the export brand of Dongguan Guohong Precision — a 10,000 m², IATF 16949 and ISO 9001 certified factory in Dongguan, China. He works directly with buyers and engineers across the automotive, medical, electronics and consumer-goods supply chains, from the first DFM conversation and tooling quote through high-volume production ramp-ups.

His day-to-day sits between the shop floor and the negotiation table: cavity steel held to ±0.005 mm, presses from 30 T to 260 T, and the sourcing decisions that separate smooth programs from costly rework. He writes this site's guides to share that know-how — no fluff, just the numbers and decisions that actually matter.

"The best molding program is the one you never have to fix — honest DFM and clear tolerance decisions up front save months and money later."
