Q

HDPE film slitting rough edge

A

For rough edge, check the blade, tension, and temperature.

Molding Process HDPE; film; slitting; rough edge; tension

Q

HDPE pipe sizing sleeve buildup

A

Sizing sleeve buildup = volatile condensation; lower the temperature and clean frequently.

Molding Process HDPE; pipe; sizing sleeve; buildup; scratching

Q

HDPE product low-temperature brittle cracking

A

Low-temperature applications: grade selection + rounded corners as double insurance.

Molding Process HDPE; low temperature; brittle cracking; impact resistance; sharp corners

Q

HDPE film poor heat sealing

A

For heat sealing, first adjust the three elements, then check the film surface condition.

Molding Process HDPE; film; heat sealing; seal strength; slip agent

Q

HDPE large-diameter pipe sag (Sag)

A

Sag is the core challenge of large-diameter thick-walled pipes; die eccentric compensation plus low-sag material plus double-sided cooling is the industry standard combination, and thickness measurement feedback can reduce trial-and-error times.

Molding Process HDPE; pipe; sag; Sag; large diameter; wall thickness

Q

COC Japan Zeon ZEONEX

A

COC ZEONEX is a well-known commercial grade; low water absorption and stability are the core values; selection ensures application quality.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Molding Process COC; ZEONEX; Zeon; water absorption; dimensional stability; heat resistance

Q

COC Amorphous Structure Transparency

A

COC amorphous transparency is the basis of optical applications; defect prevention and control is the guarantee; inspection ensures optical quality.; After confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence

Molding Process COC; amorphous; transparency; chromophoric group; optics; defect

Q

COC Ultrasonic Welding Fragmentation

A

COC ultrasonic welding requires a low-energy fine process; the weld line design of brittle materials determines the energy distribution; when the process window is narrow, alternative welding methods should be evaluated.; After confirming effectiveness, fix the parameters and practices into the w...

Molding Process COC; ultrasonic welding; fragmentation; amplitude; weld line; energy

Q

COC Microfluidic Chip Poor Bonding

A

COC microfluidic bonding is a precise balance of temperature, pressure and cleanliness; the narrow window requires high temperature control accuracy of the equipment; each batch of bonding parameters needs to be sampled by destructive testing.

Molding Process COC; microfluidics; bonding; thermocompression; channel; Tg

Q

ASA melt temperature window

A

ASA melt temperature 230-260°C normal state, 280°C is the thin-wall emergency upper limit; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence
