Extrusion Dies TRIZ Cases

Non-equiangular die bridges shift tube weld lines away from high-strain zones, reducing cracking during shaping and hydroforming.

Alternating wavy-die pressing and overturning builds uniform strain through bulk metal, enabling larger nano-grained samples with fewer passes.

Rotating the female die during isothermal extrusion forms thin-walled cabin sections with variable thickness, less waste, and higher bearing capacity.

Controlled alloy ranges and A/B composition formulas suppress quenching cracks in hot work tool steel while retaining toughness and hardness.

Localized induction heating expands the press-fit structure while hydraulic force removes the rotor shaft without damaging tight-tolerance turbomachine parts.

A movable mold element changes die geometry during extrusion to form flutes and cooling channels in cutting tool blanks, cutting post-processing and material waste.

A multi-die forming process creates a single-piece axle housing tube with 3-18 mm walls and at least 750 MPa yield strength, eliminating welding.

MR fluid-assisted wire feeding and controlled molding temperature prevent breakage in microextrusion while enabling mass production of 3D micro-parts.

Heat and pressure activate injected metal foam powder inside extruded conduits, cutting foaming cost while improving vehicle impact absorption.

An extruded multi-layer tube and louver plate assembly expands heat exchange area, boosts air turbulence, and lowers cost and refrigerant fill.

Specific alloy ranges and A/B formulas tune quench transformation behavior to limit cracking in complex hot work tools while retaining toughness.

Pre-upsetting and coaxial positioning keep the aluminum bar centered before perforation and extrusion, producing more uniform seamless pipe walls.

Sequential small-billet loading with a rotating die and cooled mandrel cuts extrusion equipment size while sustaining seamless tubing output.

Rotational shear and axial extrusion plasticize slotted Al-NCCF feedstock to form hollow profiles with lower energy use and fewer brittle intermetallic layers.

A single press with staged dies and mandrels forms axle-shaft tubes without inter-machine transfer, cutting heating, lubrication, and cycle time.

A stepped extrusion nozzle replaces repeated hot deformation, aligning thermoelectric grains in one pass to raise conductivity and cut production time.

Hydraulic ring actuation lets one extrusion die vary bore diameter in process, reducing die changes while holding ±0.005 inch precision.

Rotational shear and axial extrusion form hollow magnesium or aluminum profiles at lower energy while improving ductility and reducing cost.

A rotating scroll ram adds shear heating and flow control to produce uniform cladding, strong bonding, and lower brittleness in one step.

A single press machine combines sequential die and mandrel forming to cut axle shaft tube processing time while preserving high yield strength.

A multi-hole hot extrusion approach maintains small tube diameters and corrosion resistance while improving aluminum capillary tube output.

Segmented tungsten die surfaces and mandrel cooling help friction stir processing handle high-temperature metals and larger billets with less wear.

A W-shaped rotary extrusion cavity evens strain and grain flow in large thin-walled cabin parts, reducing opening cracks and improving yield.

Sequential billet loading on a cooled mandrel bar enables continuous tubing extrusion with smaller billets, less downtime, and lower wear.

Heterogenization precipitates Mg2Si before extrusion, lowering deformation resistance while preserving crush performance in AA 6xxx vehicle profiles.

Sequential small-billet extrusion through a rotating die cuts start-stop wear, shrinks press size, and maintains tubing output.

Rear-end holes with four sized grooves absorb breakthrough material during billet piercing, reducing burrs and internal defects in seamless pipe.

A parallel ball screw and hydraulic cylinder layout cuts extrusion discard while lowering press height and reducing hydraulic energy use.

Defined rear-end groove ratios in a heated billet absorb excess material during piercing, limiting burrs and inner defects in seamless pipe.

Dynamic die forming and segmented metal extrusions create arc-node structures with precise fit, aerodynamic surfaces, and lower manufacturing cost.

Targeted induction heating expands the press fit during hydraulic rotor shaft extraction, reducing damage risk and removal time.
