PEEK Extrusion Temperature and Residence Management

PEEK extrusion at 400-450℃ with a 30-minute residence upper limit; dead corners are the culprit; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Stress Annealing of PEEK After Machining

The dimensional stability of PEEK precision parts is backed up by stress-relief annealing below 250℃; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

The Trade-Off of 300℃ High-Temperature Annealing of PEEK

300℃ annealing is a performance-limit means, and the embrittlement and oxidation costs must be evaluated in advance; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Deformation of PEEK After Annealing

PEEK annealing is a double-edged sword — only standardized process can maximize benefits and avoid harm; annealing with fixtured shape-setting balances stress release and shape retention; any annealing specification must pass first-article verification.

Spiral Marks in PEEK Extrusion

PEEK rod spiral marks originate from the melt's rotational flow not being stabilized; a breaker plate and an extended land are the standard solutions; the influence of screw cleanliness on flow stability cannot be ignored.

Orange Peel Surface in PEEK Extrusion

PEEK orange peel treatment revolves around the three elements of melt state, die state, and cooling method; multi-stage slow cooling is more favorable to surface quality than quenching; die polishing is basic work that is often overlooked.

Rough Surface and Unmelted Particles in PEEK Extrusion

For poor plasticization in PEEK extrusion, first check the temperature system; unmelted particles are direct evidence of insufficient temperature; the die flow channel design must match the flow characteristics of high-viscosity melt.

Delamination and Peeling of PE Injection Molded Products

PE delamination = a 'contamination and compatibility' problem: first check mixed material and regrind, then control release agent and shear; for delaminated parts, don't forcibly adjust the process — find the contamination source first.

Mold Sticking of PE Injection Molded Products (Soft Material)

Soft PE demolding = the four-piece set of 'draft angle + polishing + ejection area + cooling': the softer the material, the more 'gentle' demolding must be; any concentrated force will leave permanent deformation.

Rapid Screen Pack Blockage in PE Extrusion

If the PE screen pack blocks quickly, first distinguish 'impurities' from 'gel': impurities rely on material source management, gel relies on shutdown and dead-spot management; the screen pack is a consumable and, more importantly, a diagnostic window.
