1. Realizing all related information about the mold:
  • Check the mold making design layout and material property.
  1. Before loading mold on the machine, check all mechanical movement
  • Checking molding direction, slide plate movement
  • Water channel and venting connector leaking or not.
  1. When making sure all mold movement is correct, choose the proper mold trial
  • Before choosing and deciding which mass production machine will use, pay attention to the following points:
  1. Checking Tie Bar distance
  2. Mold movement stroke size of this machine
  3. The rest of mold trial or mass production tools or accessories are all ready or not.

Load the mold and:

  • Check carefully for all mold’s mechanical movement (such as mold open & close, slides, ejector pin…etc.).
  • Operator should decreases the mold close pressure, to check/see and listen whether there is any unsmooth movement or strange sound or not under the machine manual type.
  1. Mold temperature:

As per the material’s property and the mold tool size to choose the appropriate mold temperature controller to heat up the needed mold temperature. We need to check again all the movements of the mold after the mold temperature is up.

  • This may cause expanding in the steel of mold. So we need to watch all movements in order to avoid:
  • Dragged-damage
  • Mold thrilling situation.
  1. Per the material’s difference, baking the material with the appropriate temperature.
  2. Try to use the same material for both mold trial and the future mass production.
  3. Do not use the second hand material, if there is any color requirement
  • Try to trial the material color together with the mold trial.
  1. Before the mold trial, need to adjust well the mold close pressure and try to see few times of movement:
  • To avoid causing the parts flash or mold deformation.
  1. Before making the first shot, checking the following once again:
  • Pressure is too high or too low
  • Material filling speed is too fast or too slow
  • Cycle time is too long or too short.

If cycle time is too short, ejector pins will break through the parts or damage the parts. So, we need to have well-considered of all situation and prepare the necessary solution, only by that you can avoid serious and expensive loss.
