Q

PVC Tarpaulin

A

Tarpaulin weather resistance relies on coating formulation and use management; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future

Q

PVC Card Base Material

A

Card lamination relies on parameter and material matching; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future

Q

PVC Lubrication System Balance

A

The PVC lubrication system is a fine balance of the formulation; internal and external differ, and excess and deficiency each have characteristic symptoms; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PVC Welding Assembly

A

PVC welding has two routes: heat and solvent; their quality points differ but neither can exceed the temperature limit; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PVC Wire and Cable Extrusion

A

The quality of PVC cable is electrical safety; pores and eccentricity are two major veto items, and online detection must be configured; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PVC Profile Extrusion

A

PVC profiles are the representative of extrusion precision; only coordination of the three systems—temperature, haul-off, and lubrication—can achieve stability; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Q

PVC Wire Extrusion

A

Wire material quality depends on plasticization and cleanliness; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future

Q

PVC Soft Material Temperature

A

The temperature window of soft PVC is lower than that of rigid material; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems in the future

Q

PVC Die Head Temperature

A

Die head temperature uniformity is the basis of profile quality; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems later

Extrusion & Post PVC die head temperature profile uniformity

Q

PVC Extrusion Melt Pressure

A

Extrusion stability relies on melt pressure closed-loop management; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubleshooting reference for similar problems later
