10KW Shunhao Excellent Quality Melamine Ware Preheating Machine

How to Choose a Preheater Machine?

1. Flat Plate Electrode Preheater

This model is suitable for raw materials in powder, granular, or irregular cake form. A typical application is melamine powder. Flat plate electrodes create uniform heating across the material surface. It works well for loose or non-shaped materials, ensuring consistent preheating before compression molding.

2. Roller Pole Preheater

This type is designed for preformed cylindrical blanks. Roller electrodes make full contact with the curved surface of cylindrical workpieces. It delivers even heat distribution around the round shape, avoiding overheating spots and maintaining blank integrity for the next molding process.

FAQ

Q1: How to adjust the regulator above the lid of preheater machine?

A1: Adjust the upper regulator according to the height of the material box. The upper electrode plate should not press down on the material box, and there should be a gap of approximately 3mm to 5mm between the upper electrode plate and the top of the material box.

Q2: What problems will occur if the height of the regulator is not set properly?

A2: If the adjustment of the upper regulator above the lid is too low and the material box is pressed down, it will cause the equipment cover to function abnormally, preventing the steam generated during roasting from being discharged. If the adjustment is too high, the roasting time will be extended, affecting work efficiency.

Q3: Why must the boxes used on the preheater be specially made?

A3: The preheater operates at high frequency and high voltage. During operation, it heats the raw materials, so metal boxes with good thermal conductivity and soft plastic boxes with low strength cannot be used.
