stay Horizontal injection molding machine Due to various factors, some problems often occur in the injection molding process. These problems may lead to decreased production efficiency, unstable product quality and even increased scrap rate. Therefore, it is very important to understand and solve these common problems for improving the operation efficiency and product quality of the injection molding machine.

1. A common problem is inaccurate temperature control. The injection molding process needs to control the temperature of the heater and cooler to ensure that the plastic material can reach the proper melting state and be cooled and solidified in the injection mold. If the temperature control is not accurate, it may lead to unstable product size or incomplete melting.

2. During the injection molding process, the flow channel may be blocked. Runner is the channel for plastic to enter the mold. If the runner is blocked or blocked, poor injection molding or product fracture may result. This may be caused by insufficient melting of plastic materials, unreasonable mold design or incomplete cleaning of injection molding machine

3. Bubble is one of the common problems in injection molding. Bubbles may form inside or on the surface of the product, affecting the appearance and strength of the product. The formation of bubbles is usually related to the quality of plastic materials, injection speed and pressure, so these parameters need to be adjusted reasonably to avoid the formation of bubbles

4. Product deformation is also a common problem. The product may shrink or warp during injection molding, resulting in inaccurate size or poor appearance. This may be related to the properties of plastic materials, mold design, cooling time and other factors, so mold optimization and process adjustment are needed to solve the deformation problem.

5. Impurities and color differences in the injection molding process also need attention. Impurities may come from raw materials or the injection molding machine itself, while color difference may be caused by unstable quality of raw materials or incomplete cleaning of the injection molding machine. These problems may affect the appearance and quality of products, so it is necessary to strengthen the screening of raw materials and the maintenance of injection molding machines.
