  • How to tell the plastic mould quality? Nov 23, 2018
    There are 4 aspects to adjudge whether it is a good quality mould. 1. Part quality 1.1 the stability and conformity of the part dimension 1.2 the smoothness of the surface of the part 1.3 the utilization rate of the part materials, etc 2. Mould lifetime Under the premise of ensuring the part quality, the mould is able to complete the specified cycling time or the number of parts. 3. Mould Maintena...
  • What Causes Insufficient Steel Hardness? Nov 30, 2018
    The hardness of mold heat treatment is a very important mechanical property index,it is a very serious defect when the hardness is not qualified . Insufficient or uneven hardness of the mold after heat treatment will reduce the wear resistance and fatigue strength of the mold and other properties,even resulting in early failure of the mold, seriously shorten the mold life. The Reasons Causing: 1) ...
  • Reverse Engineering in Mould Making Dec 11, 2018
    Geometric modeling technology has been widely used in the development of plastic products. However, due to various reasons, the technical data that mould makers get from clients is not the CAD model, but the physical samples consisting of complex free curves and surfaces. If using the traditional method to design and manufacture product, the cycle time is long and the cost is high. It is unable to...
  • Factors affecting the quality of die polishing Dec 11, 2018
    Since mechanical polishing is mainly completed manually, polishing technology is still the main reason affecting the quality of polishing.In addition, it is also related to mold material, surface condition before polishing, heat treatment process and so on. High quality steel is the prerequisite to obtain good polishing quality, if the surface hardness of steel is uneven or there are differences i...

  • A Good Design for Mould Air Venting Groove Jan 04, 2019
    There will be some problems like insufficient filling, compressed air burning, high internal stress inside parts, flowing mark and welding line on surface when testing molds or production. To solve or avoid these problems, we will adjust the injection moulding process first, and also consider the mould gate. When it is no problem for the injection moulding process and gate, the main way to solve t...
  • How to control the color difference of injection parts? Jan 14, 2019
    Color difference is a common defect in injection moulding. There are many factors affecting the color difference, such as raw resin, color masterbatch (or color powder), mixture of color masterbatch and raw material, injection molding process, injection moulding machine, mould and so on. Because it involves a wide range of aspects, it is recognized as one of the difficult technologies to master th...
