Describe the shortcomings of the injection clearly. And when the cause is determined. A systematic approach to deal with shortcomings, reduce and prevent them from reappearing, the most important thing to compile these strategies is to ensure that the semantics of all terms are clear and can be unde... read more
In view of the fact that most injection molding manufacturers do not produce plastic masterbatches or color masterbatches themselves. The focus of attention can be on the production management and raw material inspection to mix the two-color injection molding machine, to eliminate the influence of t... read more
The two-color injection molding technology is technically more complicated than ordinary single-color molds because it is necessary to manufacture a set of high-quality two-color molds. Moreover, many small mold factories currently do not have the ability to produce two-color molds. However, its pri... read more
(1) Temperature. The temperature has a significant effect on the plastic extrusion of the vertical injection molding machine and the performance of the parison. Increasing the heating temperature of the vertical injection molding machine will have the following effects: it can reduce the viscosity o... read more
The material pipe will cause material degradation, thereby affecting the quality of the product. What are the reasons for the screw slippage? How to "catch" the slippery screw? When the screw of the barrel is slipping, the materials probably gather at the feeding port and cannot be conveyed to the e... read more
The length of the screw is generally not measured in absolute length, but in length relative to the diameter. In this way, screws of different diameters can also be compared in length. This length is called the aspect ratio, represented by L/D. The length of the screw is of course only the part with... read more
