Q

PVC Screw Low Compression Ratio

A

The PVC screw is a dedicated part, not a general-purpose part; low compression ratio plus chrome-plated flights eliminate shear degradation from the hardware; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence
