Speed ​​is one of the key factors for the success of thin-wall injection molding. Fast mold filling and high pressure can inject molten thermoplastic material into the mold cavity at high speed to prevent the gate from being cold fixed. If a standard part is filled within two seconds, then the vertical The mold thickness of the two-color disc injection molding machine will be reduced by 25%, and the mold filling time can be reduced by 50%, only 1 second.

One of the advantages is that when thin walls are injected to reduce the thickness, less material needs to be cooled. With reduced thickness, the forming cycle can be shortened by half. Reasonably set the hot runner melt conveying device not to interfere with the runner and shorten the molding cycle. Hot runners and sprue bushings help shorten the molding cycle to a minimum. In addition, the mold material should also be considered.

P20 steel is widely used in the molding of Chinese traditional cultural products, but because of the higher pressure of thin-wall injection molding, the mold must be made very strong. H-13 and other hard steels add additional safety-related factors to thin-wall mold design. However, the cost management of solid molds may affect 30%-40% higher than industry standard molds. But the increased cost control is usually offset by continuously improving production technology performance.
