Q

PTFE Paste Extrusion Lubricant

A

Lubricant management of PTFE paste extrusion is a unique subject; compatibility selection is the foundation; removal verification prevents defects.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PTFE;paste extrusion;lubricant;removal;compatibility;residue

Q

PTFE Lining Deformation and Delamination

A

PTFE lining's thermal expansion mismatch is a structural contradiction; molding quality determines bonding reliability; negative pressure conditions are a severe test.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PTFE Filler Segregation

A

PTFE filler segregation affects the uniformity of wear resistance, thermal conductivity, and strength; mixing process is the foundation; handling management is the detail defense line.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PTFE;filler;segregation;mixing;glass fiber;uniformity

Q

PTFE Laminate Delamination

A

Cleanliness and pressure uniformity of PTFE laminates determine interlayer quality; grade compatibility is easily overlooked; non-destructive testing is quality assurance.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PTFE;lamination;delamination;bonding;contamination;grade

Q

PTFE Dimensional Shrinkage Out of Tolerance

A

PTFE's 15~20% shrinkage is an inherent characteristic of the powder metallurgy-type process; mold compensation design is the premise of dimensional accuracy; filled modification is a material means to reduce shrinkage.
