Ceramic Extrusion Dies TRIZ Cases

EDM creates width-enlarged die slits to boost isostatic strength while avoiding defects from irregular grinding.

A dual loop control system regulates barrel coolant flow to maintain precise temperature differences between the core and skin of ceramic precursor extrudates.

Offsetting supply holes from intersecting groove centers disperses stress concentrations that cause cracking during thin wall formation.

A wear resistant coating with controlled surface roughness reduces pre-conditioning time and extends die service life.

Individual zone temperature control replaces mechanical deflectors to ensure dimensional accuracy of ceramic molded bodies without clogging.

Segmented mesh plates prevent cell blockage during vertical extrusion, maintaining dimensional stability and fluid flow.

A tungsten carbide bonded assembly uses a high carbon concentration region in stainless steel to enhance bonding strength.

Trial extrusions measure end face shapes to select perforated plates that eliminate central convex defects and reduce manufacturing time.

Segmented slit geometry aligns elongated particles to reduce pressure loss and enhance gas permeation performance.

A ceramic extrusion molding method adjusts temperature control portion settings based on measured cut body dimensions to maintain target sizes.

A honeycomb structure-forming die uses columnar portions with specific height-to-width ratios to ensure high peeling strength between bonded plate members.

A honeycomb die suppresses structural distortion by nesting the cavity bore inside the back hole, ensuring uniform pressure distribution.

Segmented primary and secondary slots reduce feedhole count by 75% while maintaining uniform material distribution for proper wall knitting.

Optimizing groove depth via material elasticity parameters reduces peeling and deformation in bonded plate-like members, enhancing manufacturing precision.

Curved extrusion dies reduce peak stress and thickness by 42%, lowering pressure and tripling extrusion velocity compared to flat dies.

Interposing granules between the honeycomb body and base reduces frictional resistance, minimizing contraction differences to prevent cracking.

An extruder head uses adjustable specification elements to control strand cross-section shape and size during discharge.

An elliptical kneading element with an off-center opening axis balances radial and axial forces to promote uniform mixing of ceramic batch materials.

Drying ceramic strands before solid contact prevents sticking and enables mass production of high-strength pins.

Controlling porous silica oil absorption minimizes kneaded material water ratios, preventing partition wall shrinkage and cracks during the drying phase.

A vacuum-assisted extrusion system prevents air bubble entrainment in wet mixtures, ensuring uniform honeycomb body composition.

A motor-driven rotating disc feeds and massages clay onto surfaces through circular movements.

Co-extrusion embeds graphic material within a base substrate to create durable images that resist wear and peeling on complex topographies.
