About us
Malaysia’s first formal mold-making factory, and what grew from it.
Incorporated in 1993, Yong Heng is a Malaysia-based specialist manufacturer of thermoforming molds and die-set stamping molds.
Quality is a partnership, not an inspection at the end.
With over 30 years of experience in mold fabrication, Yong Heng is recognised as a leader in this industry for precision engineering, manufacturing reliability and consistent quality delivery.
To maintain that edge we keep investing in advanced CNC machinery, modern manufacturing technologies and disciplined quality control — the things that let us carry a customer from concept through to the final molded part.

Our founder
Mr. Chua Boon Huat
Born in Muar, Johor, Mr Chua was a mechanical technician skilled in hand-carving models. Through a mutual friend he met a packaging factory owner from Taiwan who greatly appreciated his craftsmanship, and a collaboration in making molds began.
In the early 1990s Malaysia’s mold-making industry was still in a lull and most packaging work relied on imported molds. Demand for his molds grew, including more complex electronic tray molds, until handcrafted wooden, plaster, resin and casting molds could no longer keep up.
So in 1993 he founded Malaysia’s first formal mold-making factory, upgrading from handcraft to mechanised production and investing in machinery and drawing design software — to serve the local market without importing from overseas.
