Tooling: New Safety Couplings for Mold Cooling Lines
Hasco’s new couplings have an automatic safety lock.
Hasco claims to have “set a milestone in safety standards for mold-temperature control” with its new Z80700HT to Z80801HT safety couplings. An automatic safety lock protects against accidental unlocking. Not only is a deliberate unlocking movement required of the forced rotating guide on the locking sleeve, but a clearly visible green color coding behind the locking sleeve indicates correct and safe coupling. The system still ensures easy decoupling, the company says.
The new safety couplings are suited to water or oil heating/cooling and come with high-temperature sealing rings. They come in diameters of 9 and 13 mm.
For decades molding experts have talked about the importance of achieving turbulent flow in mold-cooling circuits. But what is it about turbulence that makes it so important? What can be measured and demonstrated to have some tangible value to molders? Several months ago, the author’s firm began looking for answers.
Injection molders are warming up to the idea of cycling their tool surface temperature during the molding cycle rather than keeping it constant.
In the injection molding process, tool temperature is an important factor in achieving high-quality parts.
