I. IntroductionWhen we received a new mold and needed proofing, we were always eager to try out a result earlier and the process of prayer was smooth to avoid wasting work and causing trouble.But here we must remind two points: First, mold designers and manufacturing technicians sometimes have error

Analysis and elimination of poor surface gloss defectsLow Gloss means that the surface is dark and dull, and the transparency of the transparent product is low, which causes many reasons for poor gloss. Other injection defects are also causes of poor gloss.1, mold failureSince the surface of the pla

Four reasons of insufficient filling of injection molding products1. Improper feed adjustment, lack of material or multiple materialsInaccurate metering or improper operation of the feed control system, injection molding machine or mold or operating conditions, resulting in abnormal injection cycle,

Effect Factor of injection temperature and speed on product shrinkage1. The mold temperature is too low to solve the shrinkage problemThe problem of shrinkage of hard rubber parts (surface shrinkage and internal shrinkage) is due to the fact that the space left by the concentrated shrinkage does not

Analysis of assembly points of injection moldBefore assembly, we should carefully study and analyze the assembly drawings and parts drawings, understand the functions, characteristics and technical requirements of each part, and determine the assembly basis. Through assembly, finally achieve the pro

How to solve the sunken parts of injection molding parts?Sometimes the processed plastic injection products will shrink and sink. What's the matter? What are the causes of these situations?1. Machine sideThe nozzle hole is too large to cause the melt to flow back and shrink. Too much resistance, too

Four points of attention when burning injection productsFactor 1: Melt fractureWhen the melt is injected into a cavity with a large volume under high-speed and high-pressure conditions, the melt fracture phenomenon easily occurs. At this time, the surface of the melt breaks laterally, and the fractu

Injection mold making and mould maintenance instructionsⅠ. make the mold number1. The number of the mould must be machined with a milling machine above the outer end face of the blank (square iron) with a word height of 40mm and a depth of 0.5mm. The font is isoline.2. The number of the mold must be

What causes the dimensional instability of injection molded parts?Introduction: Plastic parts processing is the process of converting synthetic resin or plastic into plastic products, generally including plastic ingredients, molding, mechanical processing, bonding, decoration and assembly. Due to th

Seven parameters that must be taken into account when setting the injection molding process1. Injection speed:The injection speed is slower, the plastics are carried in the cavity, there will be more heat loss, the flow viscosity will increase, and the pressure loss will increase;Higher firing speed
