Q
Glass Fibre '2079851475616104452 severe flash
A
Flash is caused by high-pressure injection and mold gap; reducing pressure and improving mold fit are key
Injection Molding Glass Fibre injectionflashclamping forceparting lineinjection pressure
Q
Glass Fibre injection molded product has oil spots
A
Oil spots are caused by external sources of release agent and lubricant; reducing release agent and sealing mold lubrication are key

Q
Glass Fibre '2079851475616104452 insufficient flow length ratio
A
Insufficient flow length ratio is caused by Glass Fibre high viscosity; high temperature, high pressure and large gate are key

Q
Glass fiber reinforced plastic severe floating fiber
A
Floating fiber is caused by poor interface and injection orientation; coupling agent and reduced injection speed are key

Q
Glass Fibre injection gate freezes too early
A
Premature gate freezing is caused by small gate and low temperature; enlarging gate and raising temperature are fundamental measures

Q
Glass Fibre injection mold venting burnt
A
Burning is caused by insufficient venting and high-speed injection compressing air; increasing venting and reducing speed are key

Q
Glass Fibre mixed with color masterbatch uneven color
A
Color masterbatch carrier matching and full dispersion are the key to color uniformity

Q
Glass Fibre '2079851475616104452 warpage deformation
A
Warpage is caused by shrinkage differences and orientation stress; uniform mold temperature and holding pressure are key

Q
Glass Fibre '2079851475616104452 difficult demolding
A
Difficult demolding is caused by adhesion and insufficient mold design; increasing draft angle is the fundamental measure

Q
DSTDP periodic surface ripples
A
Ripples are caused by unstable injection; equipment overhaul and PID control are key
