Causes and Solutions of Leakage in Hydraulic System of Injection Molding Machine

Leakage is a common failure phenomenon in injection molding machines, which is mainly caused by the pressure difference and gap between the components when the hydraulic components and the liquid in the pipeline flow. In addition, poor 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 be unable to establish, and the leakage of hydraulic oil will also cause environmental pollution, affect production, and even cause immeasurable serious consequences. Below, we will briefly discuss the causes and countermeasures of the leakage of the hydraulic system of the injection molding machine.

Matching relationship between pigments, plastic raw materials and additives

The colorants used in the masterbatch must pay attention to the matching relationship between colorants, plastic raw materials and additives in the masterbatch technology. The key selection points are as follows. 1. The colorant cannot react with resins and various additives, has strong solvent resistance, low mobility and good heat resistance. In other words, the masterbatch cannot participate in various chemical reactions. Carbon black can control the curing reaction of polyester plastics, so carbon black materials cannot be added to polyester.
