Q

PEEK Fiber Floating and Appearance

A

Floating fibers rely on temperature and injection speed to promote encapsulation; mold condition also affects fiber distribution; after confirming effectiveness, fix the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a troubles...

Q

PEEK Injection Pressure and Back Pressure Window

A

PEEK requires high injection pressure and low back pressure — for shear discoloration, check back pressure and screw speed first; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence; include this case in the defect archive as a tro...

Q

Mold Steel Selection Mistake for PEEK

A

H13 is the bottom line of PEEK mold steel — the money saved on a soft mold will be repaid double in accuracy; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

The Limits of Processing PEEK on Ordinary Machines

A

For PEEK processing, first ask whether the machine can reach 400℃ — barely running at full load is a prelude to failure; after confirming effectiveness, solidify the parameters and practices into the work instruction to prevent recurrence

Q

Process Parameter Transfer Failure of PEEK

A

The essence of PEEK process transfer is equivalent reproduction of the melt state, not copying parameters; the cavity pressure curve is the best reference for cross-equipment transfer; every piece of equipment needs independent verification.

Q

Insufficient '2079851475616104452 Machine Selection for PEEK

A

PEEK's hard requirements for equipment cannot be compensated by process techniques; equipment selection mistakes are congenital defects; investing in high-temperature dedicated equipment is a prerequisite for PEEK projects.

Q

PEEK Flash

A

PEEK's high injection pressure places higher demands on clamping and mold rigidity; recurring flash mostly stems from mold wear rather than parameters; the mold maintenance cycle for high-temperature working conditions should be shortened.

Q

Floating Fibers on Glass Fiber Reinforced PEEK

A

PEEK glass fiber floating is the combined result of fluidity and temperature management; high temperature and high speed are the most effective process means; the fiber orientation direction should be planned at the mold design stage for appearance parts.

Q

Low Weld Line Strength of PEEK

A

PEEK weld lines cannot be completely eliminated — they can only be relocated and strengthened; high-temperature meeting is the first guarantee of interface strength; overflow wells are a worthwhile scrap cost for load-bearing parts.

Q

Short Shot of PEEK

A

PEEK short shot treatment follows the path of temperature first, then pressure, then structure; gate size is a hard constraint for glass fiber reinforced PEEK; high-speed filling must be implemented together with good venting.
