• The Effect of Plastic Mold Prototype Part Mar 29, 2019
    "Prototype Part" is often heard in the mold industry. It means one or a set of products processed by machine.It has two types, one is ordinary plastic part, the other is 3D printing. Ordinary plastic part refers to the processing of the plastic block directly on the machine. This kind of product is usually not large. If the part is large, the processed plastic parts need to be glued together with ...
  • Importance of adjusting the plastic injection mold temperature Mar 29, 2019
    In the injection mold industry, the design of the structure for plastic products is very important, but if the temperature of the injection mold is not reasonable, no quality products will be produced, especially in the production of POM (polyoxymethylene), PA (nylon). When do PBT and PET (polyester) material, the mold  temperature has a great influence on the plastic part. After reasonable t...
  • Reasons for Weld Line on Plastic Part Apr 04, 2019
    When we get the plastic parts during mold test, we will see some weld lines on them. What's the main reasons for the weld lines? 1. The surface temperature of the injection mold is too cold, and the surface temperature of the mold should be appropriately increased or the local temperature at the welded joint should be changed. 2. The runner is too small, too narrow or too shallow. The diameter of ...
  • The checking points for mold flash part Apr 12, 2019
    It's very common to see some flashes on the part during mold testing. Today we are going to discuss some check points when we get flashed parts. 1. Mold fitting 2. Parting Line (PL) problem (1) Check if the surface of the core is higher than the surface of the AB plate (about 0.5MM) (2) Check the flatness of the surface to see if it is deformed because the mold plate is too thin. (3) Is there any ...
  • Mold Texture Discussion Apr 12, 2019
    Texture is a common process for mold surface treatment, which directly affects the appearance and surface strength of the product surface. Mold texture, also known as mold etching, mold graning, is widely used due to its low process cost, rich effect and fast speed.  It's use chemical liquid (such as sulfuric acid, nitric acid, etc.) to chemically react with the mold steel, and the reaction p...
  • Plastic Mold Manufacturing is Importance as Well Product Design Apr 12, 2019
    When trying to develop products or new products, don't just focus on product design, neglect plastic mold manufacturing.  Some users tend to focus only on product development and development, ignoring communication with plastic mold manufacturers. After initial determination of the product design plan, there are two advantages of contacting the mold manufacturer ahead of time. 1. You can ensu...
  • The advantages for Hot Runner Mold Apr 22, 2019
    The hot runner mold refers to a mold that uses a heating device to keep the melt in the flow passage from solidifying at all times. Because it is shorter than the traditional mold shot cycle and saves raw materials, hot runner molds are widely used in various industrialized countries and regions in the world today. Shorten cycle The molding cycle is shortened. Because there is no restriction on th...
  • Injection Mold Cooling Water Leakage Failure and Troubleshooting Apr 22, 2019
    Injection mold cooling water leakage is a frequent occurrence, for many reasons, mainly in the following aspects: 1. The most occurs at the joint of the mold cooling water pipe. If water leakage is found, the sealing tape should be wound around the thread of the pipe joint and then tightened. 2. Due to long-term molding conditions, the waterproof ring inside the mold will be damaged, and the O-sha...
