Q

Warpage deformation of PP thin-wall parts

A

Thin-wall part warpage must be systematically treated from the three aspects of gate, cooling, and process; multi-point gates and balanced cooling are the two fastest-effective measures.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent re...

Molds & Tooling PP; thin wall; warpage; gate; cooling; multi-stage injection

Q

Short shot of PP thin-wall lunch boxes

A

The core contradiction of thin-wall '2079851475616104452 is the race between rapid filling and rapid cooling; high speed, high melt temperature, plus a high-flow grade is the standard solution.; after confirming effectiveness, solidify the parameters and practices into the work instruction to pre...

Injection Molding PP; thin wall; lunch box; short shot; injection speed; melt index

Q

Environmental humidity influence on BOPP film

A

Environmental management is an invisible variable of BOPP quality; a constant-temperature and constant-humidity workshop is the standard configuration for high-end film production.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Processing Machinery PP; BOPP; humidity; environment; corona; cleanliness

Q

Poor roll formation of BOPP film

A

Film roll quality is the concentrated embodiment of various deviations of the production line; tension management and thickness control need to be improved simultaneously.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PP; BOPP; winding; film roll; tension; storage

Q

Temperature-sensitive fluctuation of BOPP film

A

Temperature stability is the foundation of BOPP quality consistency; the return on investment in precision temperature control is directly reflected in the qualification rate.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PP; BOPP; temperature; fluctuation; temperature control; consistency

Q

Poor adhesion of BOPP film

A

Adhesion problems are solved from both surface treatment and cleanliness; dyne value testing is the quantitative basis for release.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PP; BOPP; adhesion; corona; dyne value; printing

Q

Optical defects of BOPP film

A

Optical defects are traced to the raw material and filtration links; high-transparency film must use high-cleanliness raw materials with high-precision filtration.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PP; BOPP; optical defects; gel particles; resin; filtration

Q

Static electricity problem of BOPP film

A

Static management is a necessary condition for BOPP high-speed production; material antistatic and environmental control work together.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Material Drying PP; BOPP; static electricity; antistatic; ionized air; humidity

Q

Edge defects of BOPP film

A

Edge cutting quality depends on the condition of the slitting equipment; tool management and parameter standardization are the guarantee of edge quality.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PP; BOPP; edge; slitting; burr; cutting tool

Q

Wrinkles in BOPP film

A

The direct cause of wrinkles is tension imbalance; closed-loop tension control plus thickness uniformity management can significantly reduce the wrinkle occurrence rate.; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Extrusion & Post PP; BOPP; wrinkles; tension; alignment; speed
