KOSMEK GWA Die Clamps
Request a Quote
This GWA die clamps are equipped with a self-lock structure. This means the oil pressure will return to zero after the clamping, without sacrificing the clamp performance, making them highly reliable die clamps.
These die clamps are used for mold plates without a T-slot, but have a higher mold size conformance, meaning the mold plate size can't be freely changed.
