  • Shot Weight Injection Molding Calculation - Zhongde
    In this post, we will explore the concept of injection molding shot weight, its importance, principles of calculation, and step-by-step methods for calculating shot weight in both hot-runner and cold-runner systems
  • Plastic Residence Time: Calculation and Process - Rosti
    Small shot sizes that use minimal barrel capacity can result in long residence times and polymer degradation On the other hand, large shot sizes and more than 50% of barrel capacity can result in poor melt uniformity and long screw-recovery
  • Three Considerations to Determine Injection Molding Machine . . .
    1) Do the mold dimensions fit between the machine tie bar spacing and within the platen? 2) Is the machine clamp tonnage sufficient? Calculate estimated machine clamp tonnage by multiplying the part’s projected surface area by the clamping force factor for the specified plastic material
  • A Simpler Way to Calculate Shot Size vs. Barrel Capacity
    Large shot sizes, using greater than 65% of the barrel capacity, tend to have melt-quality issues like unmelt, poor melt uniformity, and long screw-recovery times It’s great if you find one screw that can accommodate all your parts; but if not, consider ordering two barrels
  • How to Select Injection Molding Machine: An In-Depth Guide
    Size and weight of the part significantly influence the size of the machine that you will need For instance, if the part is large and heavy, a machine with a larger clamping force and a larger mold space is needed
  • Shot size formula in injection moulding - Kruger Industries
    Step-by-step calculations for product mould shot size in injection moulding: Product Mould shot size = spruce volume + runner volume + product volume+ shrinkage Step-by-step calculations for machine shot capacity shot size while designating injection moulding machines
  • ARBURG: How feed rate, injection volume and filling time . . .
    The achievable injection speed in mm s is one of the characteristic indicators for the technical performance of an injection moulding machine The use of mm s actually comes from the machine tool industry, which describes the linear feed rate of an axis
