• Injection mold cooling lines leakage fault and troubleshooting method Aug 11, 2021
    Injection mold cooling line leakage is a common occurrence. There are many reasons, mainly from the following aspects: 1. Most occurs at the joint of the mold cooling lines. If leakage is found, the sealing belt should be wound on the thread of the pipe connector, and then tightened. 2. Due to long-term molding conditions, the o-ring in the mold will be damaged, and the O-shaped o-ring is eas...
  • Injection mold maintenance skills Aug 11, 2021

  • Notes on injection molding of double color mould Sep 10, 2021
    The process of double color injection molding is a very strict process. If you want to make a good mold, you must strictly control the process of injection molding. In particular, it is necessary to understand the precautions of injection molding of the two-color mold, so as to better avoid some unnecessary problems in the process of injection molding of the two-color mold. So what shoul...
  • What is the use of a lateral demoulding mechanism in a mold? Sep 10, 2021
    Injection parts need to overcome the friction between parts and mold, to overcome atmospheric pressure (some semi-closed shell, cylinder parts), but also overcome the friction between the mold mechanism itself. Therefore, in order to overcome the demoulding force and ensure the stable work of injection mold, many exquisite demoulding mechanisms were born. These mechanisms can be divided ...
  • Quick delivery plastic turnover box mold Sep 23, 2021
    As we all know, shortening the production time per unit time can increase output. Reducing the cycle time of the circulating box mold can not only improve output, but also save a lot of processing costs and bring more benefits to manufacturers. So how can you achieve a shorter cycle? Green Vitality Industry Co., Limited has more than 20 years of experience in plastic injection molding of...
