PLASTIC & INJECTION MOLDING

Complete Variable Quick Mold Change Solution

HYDRA-JAWS™ Quick Mold Change

Hydra-Jaws™ systems are shipped prepared for easy installation. Simply bolt the platen plates onto the machine's platens, install manifolds, place clamps in slots and connect hoses and you're ready for production.

Once the Hydra-Jaws™ Hydra-Mechanical clamps are moved into position hydraulic pressure is applied creating high clamping forces. During production, the clamps are mechanically locked and require no hydraulic pressure. This combination allows you to enjoy both the power and speed of hydraulic clamping and the security of mechanical locks.

STEP 1

Locate the mold using the Mold Locating Guide Slot and close the moving platen. Move the clamps into position for clamping.

STEP 2

Apply hydraulic pressure to the clamps and set the mechanical locks.

STEP 3

Release the hydraulic pressure and disconnect the hydraulic power supply from the system.

Selecting Your System

All systems provide adjustability for mold size, clamping plate thickness and left/right or top/bottom clamping.  SPI standards for platen bolt patterns and knockout patterns apply. Fixed 'A' side plates are equipped with center locating hole and optional guide slot leveling feature available on nearly all sizes. Clamping force is based on 5,000 psi hydraulic pressure typically provided by PFA's Power Control Module. Custom clamp ranges, larger clamps for larger mold weights, and/or custom plates and higher clamping forces are available.

*Plates for systems J8825, J8835 and J8980 are often made to order, please contact a PFA representative for assistance.
**Typical Max. Mold Weight is based on rated weight per platen with a typical 60/40% weight split. Per platen ratings are based on historic ratings for typical molds with typical (low) opening forces. Molds not evenly divided must be sized on a per platen basis using the heaviest half. As some mold applications may involve larger than typical opening forces or other forces on the clamps, clamp size should be checked and selected based on the most demanding mold application for the press and in accordance with the customers in plant clamp force guidelines.

Note : All products are assumed to be operated by PFA hydraulic sources at standard pressures of 5,000 psi hydraulic.
