  • What Tube brand for the preheater: Toshiba or Canon?
  • Actually Toshiba and Canon are the same since they both are from the same Japanese company. It's important to note that Toshiba was the former brand, and Canon is the current brand.

  • What are the tube models of preheaters for melamine moulding compound?
  • All Shunhao brand preheating machines are equipped with Canon brand tubes.

    5KW model: 7T69RB

    7KW model: E3069RB

    10 KW standard model: 8T20RB, expensive but long life and strong quality

    10 KW cheap model: E3130, cheap but short time life (1.5 years)

  • Is there any different tube used for 10KW preheater for melamine molding compound?
  • Yes, there are 2 types of vacuum tubes running for 10 KW preheater.

    Standard model: 8T20RB, expensive but long life and strong quality;

    Cheap model: E3130, cheap but short time life (1.5 years)

  • What are the preheating machine models?
  • 5KW preheater: 150T/200T/250T melamine crockery molding machine

    7KW preheater: 200T/250T/300T melamine crockery molding machine

    10KW preheater: 300T/500T/600T melamine molding machine

  • How to run the melamine preheating machine?
  • 1. After installing the electronic tube, turn on the power for more than 10 minutes.

    2. Adjust the timer to test for accuracy of timing and check whether the cover is open or not as timer showing.

    3. Check the status of cover open and close, whether the equipment work smoothly (visual inspection).

    4. The new machine can be put into normal use after the above steps are normal.

  • How is the shipping and packing for preheating machine?
  • Packing with wooden box, seaworthy packing during LCL shipping, or FCL shipping.

  • Why melamine powder needs preheating while Urea doesn't?
  • 1. Preheating the melamine powder can reduce the molding time and improve work efficiency.

    2. After the melamine powder is preheated and comes to powder cake, to reduce the rate of shortage powder and also reduce the water waves of the melamine tableware.

    3. In theory, UREA can also be preheated. But the characteristics and plasticity of UREA material are higher than melamine powder, few factories use preheating machine for urea powder, but melamine powder requires the preheating machine.

  • Why the box must be specially made for preheating?
  • The preheating machine is in a high-frequency and high-pressure work to heat the raw materials, so you cannot use a thermally conductive metal box or a soft plastic box with low strength. The special made plastic preheating box can get a better powder cake after preheating.

  • How to adjust the preheater regulator above the cover?
  • 1. Adjust the upper regulator according to the height of the powder box. The upper pole plate cannot press the powder box, the distance is about 3mm to 5mm, away from the top of the powder box.

    2. If adjusted too low or even press the powder box: it will cause the cover closing abnormally, and the water vapor during baking cannot be exhausted out.

    3. If adjusted too high, the baking time will be prolonged, affecting work efficiency.

  • What will cause if the preheater contactors and relays are broken?
  • Reason

    Troubleshooting

    The burned out phosphor bronze sheet on the upper cover will cause the damage (oxidation) of the lower corner copper when closed. It also causes frequent cover jumps and accelerated aging and damage of the tube.

    Replace the damaged phosphor bronze in time

    Burning and oxidation of the high-voltage output copper sheet and grid copper sheet will cause frequent cover jumps and accelerate the aging and damage of the electronic tube.

    Replace the high-voltage output copper and grid copper

     

  • Why qualified capacitors work well for a preheater?
  • Poor quality capacitor can easily cause failure or any trouble for the preheater machine, which increase the running cost. Shunhao suggest purchasing original Genuine capacitors.
