Q
Glass Fibre extrusion unstable dimensions
A
Extrusion dimensional stability depends on feeding accuracy, temperature control and haul-off synchronization
Extrusion & Post Glass Fibre extrusiondimensional stabilityfeeding controltemperature PIDhaul-off synchronization
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
Injection Molding Glass Fibre injectionflow length ratiomelt viscosityinjection temperatureflow aid
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
Injection Molding glass fiber floating fibercoupling agentMAH compatibilizerinjection speedglass fiber length
Q
Glass Fibre extruded pipe sizing sleeve material sticking
A
Sizing sleeve material sticking is caused by elastomer adhesion characteristics; polishing and lubricating water are key
Molding Process Glass Fibre pipesizing sleeve stickingpolishinglubricating waterelastomer adhesion
Q
Glass Fibre extruded pipe rough inner wall
A
Pipe inner wall roughness is caused by mandrel condition and insufficient cooling; polishing mandrel and internal cooling are key

Q
Glass Fibre film blocking, difficult to separate layers
A
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
Injection Molding Glass Fibre injectiongate freezingholding pressure transmissiongate sizemold temperature
Q
Glass Fibre extrusion unstable feeding
A
Unstable feeding is caused by pellet characteristics; loss-in-weight feeding and anti-bridging are the core

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
Injection Molding Glass Fibre injectionmold burningvent grooveinjection speedair compression
Q
Glass Fibre mixed with color masterbatch uneven color
A
Color masterbatch carrier matching and full dispersion are the key to color uniformity
