Therefore, the moisture content of plastics affects the processing of plastics. An important factor in process, product appearance and product characteristics that must be monitored. 1. The following product defects may occur in plastic injection molding products affected by moisture content: 1). Product dents and bubbles – caused by hygroscopic materials that are not well dried, and residual monomers and other compounds in the materials. To determine the cause of the pores, just observe whether the bubbles of

Plastic injeciton molding weld lines or weld seams is occured whe melted plastics meet in the form of multiple strands in the cavity due to encountering insert holes, areas where the flow rate is discontinuous, and areas where the filling material flow is interrupted. Produces a linear weld seam, and also creates a weld seam when gate injection filling occurs. This kind of weld line only occurs at the junction of the molten material (using a gate, the products that do not make the material merge from two directions generally have no weld line), that is to say, it only occurs in the molded part with holes, or multiple pouring Mouth-molded

Here we would like introduce the cause and treatment of injection molding machine hydraulic oil leakage, and how to find out and fixed the oil leakage issues. 1. General overview Injection Molding Machine Hydraulic leakage is a common fault phenomenon in injection molding machines, mainly due to the pressure difference generated when the liquid flows in the hydraulic components and pipelines, and the existence of gaps between components. In addition, harsh working conditions will also have a certain impact on the sealing of the injection molding machine. Once the hydraulic system leaks, it will cause the system pressure to fail to build up, and the injection machine hydraulic oil leakage will also cause environmental pollution,
