How to Deal with the Short Filling of Products during Injection? The short filling of glue is a common problem, but it’s not difficult to solve. When technical means can’t solve the problem, it can be improved by the design and manufacture of molds. Tips: When such problems occur, it is necessary to observe the … Read more
Why Should the Injection Mold Be Equipped with An Exhaust System ? The exhaust of injection mold is an important issue in mold design. Especially in rapid injection molding, the requirements for the exhaust of injection mold are more stringent. The necessity of Exhaust System 1. The source of gas in the injection mold. 1) The … Read more
Solution to the Color Problem of Injection Molded Products Causes of uneven color of injection molded products The main reasons and solutions for the uneven color of injection molded products : (1) Poor diffusion of the colorant, which often causes streaks near the gate. (2) The thermal stability of plastics or colorants is poor. To … Read more
How to Choose the Screw of Injection Molding Machine? As we all know, the “screw plasticizing component” is the main core unit of the injection molding machine. And it directly reflects the performance of the injection molding machine. The screw is a crucial part, whose performance determines the quality and efficiency of the processed products. With the … Read more
How to Solve the Cracks on the Surface of Injection Molded Products? Reasons and solutions for the molding cracks 1. The residual stress is too high. For the mold design and production, we can adopt direct gates with minimal pressure loss and higher injection pressure. We can change the forward gate to multiple pin point gates or side gates, and … Read more
Process Principle and Requirements of High-gloss Injection Molding Process principle of high-gloss injection molding The mold is heated before and during mold clamping. After completing mold clamping, the injection will start when the temperature reaches the set conditions. The mold continues to maintain a high temperature during the injection process. So the rubber can maintain … Read more
Service Life of Plasticized Components of Injection Molding Machine Brief introduction of Plasticized Components Plasticized components includes screw, melt barrel, rubber head, rubber ring, rubber gasket. When the injection molding machine is working, the plasticized components are like the wheels of a motor vehicle. So when the machine start working, the components will begin to subject to pressure, impact, … Read more
Analysis and Countermeasures of Poor Gate Cutting Poor gate cutting It refers to a phenomenon in which the gate connecting the molded product, the main runner, and the sub-runner is not easily cut off when molding with point gates. If you use point gates or latent gates, when the mold is opened and connected with products, … Read more
Advantages of Using Small Gates for Injection Molding Introduction of the Small Gate The gate is a critical section of the material flow channel in the gating system. Except for the main runner gate, most gates are the smallest part of the gating system with the smallest cross-sectional area, and its value is generally only 3%-9% … Read more
Important Points of Injection Molding Machine Barrel The barrel and screw constitute the extrusion system. Like the screw, the barrel also works under the conditions of high pressure, high temperature, severe wear and corrosion. In the extrusion process, the barrel is also used to transfer the heat to or away from the material. Besides, barrel … Read more
