PVC Soft Extrusion Temperature

Soft PVC temperature management must also protect plasticizer; overheating loses not only appearance but also flexibility; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PVC; soft; plasticizer; exudation; 130-170℃

PVC Extrusion Pipe Temperature

PVC pipe extrusion is the art of zoned temperature control; each zone has its duty, local overheating immediately shows; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PVC; extrusion; pipe; zoned temperature; die head

PVC Profile Uneven Cooling Deformation

PVC profile bending = 'cooling and haul-off straightness': uniform cooling and straight haul-off are the two elements; calibration die condition directly determines profile straightness; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence.

PVC Extrusion Output Decline

PVC output decline = 'wear + screen blockage': PVC fillers are highly abrasive, screw life is short; wear-resistant materials and regular clearance measurement are the hardware basis for maintaining output; after confirming effectiveness, fix the parameters and practices into the work instruction...

Extrusion & Post PVC; extrusion; output; screw wear; screen pack

PVC Profile Co-extrusion Layer Peeling

PVC co-extrusion peeling = 'interface temperature and matching': the two layers must be fused in place with good synchronization; co-extrusion interface bonding is the core, formula and temperature must match.

Extrusion & Post PVC; profile; co-extrusion; peeling; interface

PVC Pipe Extrusion Melt Fracture

PVC melt fracture = 'shear exceeding limit': raise temperature, reduce speed, polish, optimize lubrication; PVC is heat-sensitive, raising temperature must be cautious — lubrication and speed adjustment are often safer.

Extrusion & Post PVC; pipe; melt fracture; die; lubrication

PVC Film Gel and Specks

PVC film surface spots = 'plasticization + dispersion + dead corners': plasticization and additive dispersion are the main line, dead corner burnt material is the hidden danger; film has the highest uniformity requirement, plasticization must be excessive.

Extrusion & Post PVC; film; gel; plasticization; dead corner

PVC Profile Dimension Fluctuation

PVC profile dimension fluctuation = 'extrusion + haul-off + calibration' three-stability problem: first stabilize extrusion output, then synchronize haul-off, finally calibrate the calibration; the matching degree of the three determines dimensional accuracy.

Extrusion & Post PVC; profile; dimension fluctuation; haul-off; vacuum calibration

PVC Profile Surface Streaks

PVC streaks = 'die condition + plasticization uniformity': buildup shedding, die damage, poor plasticization are the three sources; the regularity of streaks can infer whether it is periodic buildup or persistent damage.

Extrusion & Post PVC; profile; streak; die; plasticization
