A Bit About Us

Western Quality at Chinese Prices

We offer the unique solution of providing western customers with the same high-quality results they would expect in their own countries, but at much lower Chinese prices.

We work on a cost-plus basis, and are always fully upfront about how much you can expect to pay. We’ve built a very strong reputation for creating such high-quality molds, and we strive to uphold that reputation.

Save Up to 50% on Tooling Costs

If you try and source a plastic injection mold from Chinese companies directly, you’ll likely run into quite a few problems and false starts.

By sourcing your molds through us, you could save up to 50% on your tooling costs compared to a US-based manufacturer — while lessening the risk of receiving substandard molds.

With our very own factory, we specialize in building highly precise, superior quality plastic injection molds. We take care of everything in-house, instead of outsourcing parts of the process to others.

How It Works

Plastic Mold & Injection Molding Process

The same parts can be made thousands — or even millions — of times with perfect consistency and minimal waste.

1

Plasticizing & Metering

Plastic pellets are fed into a heated barrel where a rotating screw melts and conveys the material forward, building the precise melt volume needed for each shot.

2

Injection & Volumetric Filling

The screw acts as a piston, injecting melt into the closed mold cavity under high pressure (typically 300–1,200 bar), forming a thin skin layer against the cold mold wall.

3

Holding Pressure

After filling, holding pressure compensates for material shrinkage until the gate seals — critical for part weight consistency and dimensional accuracy.

4

Cooling

The mold’s cooling channels extract heat until the part is dimensionally stable. Cycle time is primarily determined by cooling capacity and wall thickness.

5

Ejection & Mold Protection

Once cooled, clamping force is released and the ejector half moves back. The built-in mold protection system halts clamping if any foreign object is detected, preventing costly mold damage.
