How it Works ?

• Granular material is fed from hopper into the cylinder

• Plastic is heated and melted

• Cylinder screw forced out the plastized (while still melted)

• Melted plastic enter the mold through a nozzle (injection).

• Held closed by clamping mechanism.

Mold Technology

1. Stack Molds• High part volume • Keep costs-to-manufacture low.

2. Unscrewing Molds• Cap and Closure molds, and other products with thread and precision.

3. Spin Stack Molds >>• Multi operations in a rotating, four-face cube mold decorating/labeling, assembly. • Reduce manufacturing costs and improve quality.

4. In-Mold Technology• In-mold labeling and in-mold decorating • In-mold closing of closures with living hinges, and in-mold assembly.

5. Multi-Material/Two Shot >>• Multi-material or multi-color components can be molded in a single cycle.• Broad range of products from consumer to technology products and packaging
