High Frequency Preheating Machine for Thermoset Powder Processing

The High Frequency Preheating Machine is designed to preheat thermosetting powder materials such as melamine and urea formaldehyde. It uses high-frequency electromagnetic waves to rapidly heat powders before they enter the molding press. This reduces cycle time, increases surface smoothness, and improves product consistency.

Thermoset Heating Machine – Improve Molding Efficiency

This thermoset heating machine delivers internal and external heat balance, removing moisture and air pockets within seconds. Compared to conventional electric ovens, it avoids surface charring and deformation. The uniform heating helps improve the bonding strength and final finish of molded products.

Preheating Equipment for Melamine and Urea Applications

This preheating equipment is ideal for melamine tableware, urea toilet seat covers, trays, bowls, and similar heat-cured products. With precise PLC control, operators can adjust time, frequency, and power to suit each formulation. It saves energy, reduces mold wear, and enhances surface color stability.

Benefits of High Frequency Powder Preheating

• Fast, even heating for powder raw materials

• Improves product yield and cycle time

• Clean, safe, and energy-efficient operation

• Adjustable timing and power settings

• Compact design, easy integration into production lines
