Rams/Plungers TRIZ Cases
- Expandable Dummy Block Structure for Higher Extrusion Pressure
A separate plunger disc and shaft let the disc deform outward and expand the collar, improving billet force transfer at higher extrusion pressure.
- Extrusion Press Dummy Block With Elastic Plunger Disc
A separate elastic plunger disc and shrink-fitted collar improve billet force transfer, reduce jamming, and support higher extrusion pressures.
- Hollow Extruded Profile Correction for Accurate Mating Surfaces
Rubber bulge forming expands selected hollow extruded sections to improve mating-surface accuracy without costly post-extrusion machining.
- Extrusion Press Floating Bearing for Uniform Pressing Force
A floating bearing between the motor drive and press module absorbs transverse forces, reducing oscillations and improving extrusion uniformity.
