Shrinkage, shrinkage, unsaturated mold, burrs, weld marks, silver, jetting, charred, warpage, cracking / breakage, and other common size tolerance problems described injection, cause analysis, and in the mold design, molding Solutions aspects of process control, product design and plastic materials.
　　● lack of plastic injection molded perimeter, analysis and countermeasures reason unsaturated die
　　Causes ● batch front (burr) and Solutions
　　● surface glycidyl injection, analysis and countermeasures reason shrinkage (vacuum bubbles) in
　　● crazing ( material flowers, spray), burning, the gas lines Causes Countermeasure
　　● injection water wave surface, rhyolite and solution for analysis (flow mark) Countermeasures
　　● folder Watermark injection surface (weld line), the injection lines ( Causes serpentine) and Solutions
　　● injection surface cracks (cracks), analyze and address the causes of white top (top burst) Countermeasures
　　● color injection surface, poor gloss, color mixing reason, black stripes, black dots analysis and countermeasures to solve
　　● warpage of injection molded parts, and the analysis of the causes of the Solutions stress cracking
　　● Cause analysis of Solutions of injection-molded part dimensional variations
　　● injection molding member sticking tow flowers (strain), and solution for analysis drag white Measures
　　analysis Causes and Solutions ● insufficient transparency in injection molding, insufficient strength (brittle fracture) of
　　● injection for a cold surface, and countermeasures Cause analysis peeling (delamination) of
　　● Notes Analysis Causes and Solutions metal insert member failure
　　● nozzle drool (runny nose), drooling, drawing nozzle, analyze the causes nozzle clogging, difficulty of mold and improvement measures
　　● using a mold flow analysis CAE rapidly effective solution injection site problem
