Q
DSTDP injection cold slug marks
A
Cold slug marks are caused by solidified residual material in the nozzle; raising nozzle temperature and cold slug well design are key
Injection Molding DSTDP injectioncold slug marksnozzle temperaturecold slug wellinjection pressure
Q
DSTDP extruded film winding wrinkling
A
Film wrinkling is caused by tension fluctuation and uneven thickness; automatic tension control and uniformization are key
Extrusion & Post DSTDP filmwinding wrinklingtension controlthickness uniformityguide roller parallelism
Q
DSTDP injection flow marks
A
Flow marks are caused by unstable injection front and rapid cooling; multi-stage injection and high mold temperature are key

Q
DSTDP repeated processing performance decay
A
Multiple processing performance decay is caused by thermo-mechanical degradation; limiting regrind and supplementing antioxidant are key

Q
DSTDP extruded film thick edges and thin middle
A
U-shaped thickness is caused by die flow channel and swell differences; coat-hanger die and gap fine adjustment are key
