About the company
Muar, Johor
Trusted thermoforming mold specialist since 1993, serving Malaysia and international markets.
What we build
01 — Forming
02 — Cooling
Pressure boxes with cooling system
Ports, manifold and circuit laid out together with the cavity field, not after it.
03 — Trimming
Inline punch & die stamping molds
Die sets for three and four station machines, with the stacker matched to the trim.
In the tool room
A mold is finished when it runs, not when it is cut.
One-stop mold solutions that add value
01 — Productivity
Shorter cycle times
Optimised mold design and enhanced cooling shorten cycle times, enabling more frequent mold usage and improving overall production efficiency.
02 — Cost
Reduce cost, grow profits
Engineered for durability and long service life under high production volumes, typically exceeding nine months of continuous operation.
03 — Machine
Extend trimming machine lifespan
Precision tooling reduces machine force and vibration, lowering maintenance and extending the life of trimming and forming machines.
04 — Safety
Enhance workplace safety
Efficient mold design reduces production noise and improves operational stability, supporting a safer working environment in line with occupational safety requirements.
