To overcome the temperature sensitivities of optical materials like PC, PMMA, and cycloolefin copolymers, a new hot runner system eliminates local overheating of material and long residence times. The ...

A hot runner system is designed with heaters providing goodcontact on the machine surface because of the round P20 steel design. The radial matched heater construction increases the material ...

The company has developed integrated hot-runner technology, combining a unitized design with a simple mold-design modification. Injection molders benefit from the integrated approach in several ways: ...

Cycle time is the primary cost measure of the molding process, and cooling represents about 80% of the molding cycle (see Figure 1). The thicker the part, the longer the cycle time. However, the ...
