Melt fluidity of modified cellulose acetate butyrate changes significantly (better or worse)

Fluidity changes require process adjustment to match the modified material

Material Analysis fluiditymelt viscosityprocessing parameters

Design problems (wall thickness, rounded corners, ribs) affect processing quality

Product design needs to follow basic plastic design principles

Production & Quality product designwall thicknessrounded cornersribs

Insufficient bonding force between metal layer and substrate after CAB product electroplating

CAB electroplating requires optimizing roughening and activation processes

Material Drying CAB electroplatingrougheningplating adhesion

Bubbles appear inside or on the surface of extruded products

Extrusion bubbles need to be addressed from drying and venting

Material Drying extrusion bubblesdryingventingtemperature

Product has burning, poor plasticization, or unstable color

Screw speed needs to match back pressure to avoid excessive shear

Processing Machinery screw speedshearback pressureplasticization

Gate type, size, and position design affect product quality

The gate needs to be reasonably designed according to material and product

Molds & Tooling gate designgate typegate position

Middle zone temperature fluctuation causes unstable melt viscosity

Middle zone temperature needs to ensure uniform melt plasticization

Material Analysis middle zone temperaturemelt uniformityplasticization

Gloss fluctuation affects appearance quality consistency

Gloss requires stable mold temperature and mold surface
