PEEK Fiber Floating and Appearance

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...

PEEK Injection Pressure and Back Pressure Window

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...

Mold Steel Selection Mistake for PEEK

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

The Limits of Processing PEEK on Ordinary Machines

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

Process Parameter Transfer Failure of PEEK

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.

Insufficient '2079851475616104452 Machine Selection for PEEK

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.

PEEK Flash

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.

Floating Fibers on Glass Fiber Reinforced PEEK

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.

Low Weld Line Strength of PEEK

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.

Short Shot of PEEK

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.
