Q

Uneven heating of PP '2079851475616104458 sheet

A

The wall thickness distribution of '2079851475616104458 starts from the heating uniformity of the sheet; zoned temperature control is a fine adjustment means.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

Unclear detail replication in PP/TPO '2079851475616104458

A

Detail replication in '2079851475616104458 depends on 'vacuum in place + sufficient temperature + slow speed': for unclear details, first check whether the vacuum system truly establishes sufficient pressure differential, then supplement temperature; texture areas often also require separate cons...

Q

Chill marks in PP/TPO '2079851475616104458

A

A chill mark is the mark left by 'touching a cold surface too early': raise the mold/plug temperature and postpone the contact timing, and the problem disappears; this is a typical temperature management problem, not a material problem.

Q

Webbing (material pile-up) in PP/TPO '2079851475616104458

A

The key to preventing webbing in olefin sheet '2079851475616104458 is 'pre-blow + temperature control + early vacuum': managing the excess material with pre-stretching is more controllable than simply cutting the sheet smaller, and deep-cavity parts especially cannot do without plug assist.

Q

PP '2079851475616104458 Cold Mark

A

Cold marks are surface evidence of improper temperature management; both sheet and mold temperatures must be within the window.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
