PFA Inc. offers a quick mold change (QMS) system ideal for non-magnetic mold clamping with consistent force and mechanical clamping advantages.

The PFA Hydra-Jaws QMC system replaces common mechanical clamp systems and bolt-through fastening methods with its flexible hydraulic mechanical clamping system for use with a variety of mold base dimensions and base materials.

Shops can now more quickly change out molds with insulator plates, non-magnetic materials such as aluminum, and rough or uneven surfaces in support of Single Minute Exchange of Die (SMED) programs. Shops using mechanical clamping systems also have minimal maintenance needs.

The hydra-mechanical clamp design allows hydraulic pressure to perform consistent force clamping. This function ensures that equal pressures and known clamp tonnage is applied to the mold. After clamping, operators easily spin locking nuts on each clamp to the clamp body, securing the clamp mechanically at tonnage. They can then remove hydraulics with the clamps mechanically securing the mold to the platen.

Made-to-size bolt-on platen plates with boomerang-shaped slots are commonly requested; however, systems are available to match a variety of needs, including multiple slotted plates, single-side clamping, and in-machine platen slots.
