Q

Pulsating Droplets at the Die Exit

A

This problem is a typical manifestation of pulsating droplets at the die exit in extrusion molding. The core of the solution lies in eliminating the root cause of the defect through systematic optimization of process parameters (temperature, speed, pressure) and precision correction of the die/si...

Q

Thermal shock cracks caused by opening the furnace too quickly after sintering is completed

A

The essence of cracking is that the internal stress exceeds the strength limit of the material, and it is necessary to proceed from two aspects: reducing stress concentration and improving material toughness.

Q

Blank delamination during cold-press preforming

A

The essence of the interlayer separation problem is insufficient interfacial bonding force, which needs to be systematically improved from three aspects: impregnation quality, interlayer cleanliness, and process parameters.
