Q
Material Changeover Residue of CMC
A
Changeover residue is caused by incomplete cleaning; thorough cleaning and disassembly are the key
Processing Machinery CMCchangeover residuepurging materialscrew disassemblydead corner cleaning
Q
Fast UV Aging of CMC
A
Fast UV aging is caused by photo-oxidation; UV absorber and HALS are the key
Material Analysis CMCUV agingUV absorberHALSradical scavenging
Q
Unstable Shrinkage of CMC
A
Unstable shrinkage is caused by batch differences and temperature fluctuations; raw material and temperature control are the key
Material Analysis CMCshrinkagebatch differencetemperature control stabilitycrystallization consistency
Q
Coarse Internal Crystallization of CMC
A
Coarse crystallization is caused by slow cooling; fast cooling and nucleating agent are the key
Molding Process CMCcoarse crystallizationspherulite refinementnucleating agentcooling rate
Q
Unstable Weight of CMC Injection Molded Products
A
Product weight stability depends on injection amount accuracy and holding consistency

Q
Poor Weather Resistance of CMC
A
Poor weather resistance is caused by photo-oxidation; UV+HALS+antioxidant triple protection is the key
Material Analysis CMCweather resistanceUV absorberHALSphoto-oxidation
Q
Out-of-Roundness of CMC Extruded Pipe Exceeding Standard
A
Out-of-roundness is caused by uneven cooling and clamping; annular cooling and uniform haul-off are the key

Q
Large Current Fluctuation of CMC Extruder
A
Current fluctuation is caused by unstable feeding, poor temperature control and unsuitable screw; system optimization is the key
