Application of high frequency preheater

• Electronic component manufacturing industry, preheating of melamine tableware, bakelite powder and other special materials before molding.
• Can make the temperature of the object rise to 100~150℃ in a few seconds to ten seconds, and evenly preheat. 
• Prevent bubbles, stains and marks, increase product output, improve appearance, and reduce defective products.
• The material after high frequency preheating can easily flow to every corner of the mold, making the mold more durable and reducing defective products!

Suggestions for Preheating Machine

If it is a single color molding machine, it should be equipped with 1 preheating machine

• 150T-250T machine is suitable for 5KW/7KW preheating machine
• Machines above 300T level is suitable for 10KW preheating machine

If it is a double color molding machine, it can be equipped with 1 or 2 melamine preheating machines (according to the requirements of the operation process or the habits of factory workers)

The function of the high-frequency preheating machine

The material heated by the high-frequency preheating machine can enhance fluidity, shorten the die casting time, eliminate the internal stress of the material, eliminate the product water mark and improve the finish of the finished product, save the amount of material, and extend the mold life.

Product Features of high frequency preheater

1. Working principle of high-frequency preheating machine: high-frequency (high-frequency) dielectric heating mode, the heated material is heated quickly and evenly due to dielectric loss in a high-frequency electric field.

2. High-frequency preheater application industry: widely used in compression molding industry, such as semiconductor discrete electronic components, integrated circuits, other microelectronic packages, motor commutators, melamine (melamine) melamine tableware, plastic appliances, etc.

3. Materials that can be heated by the high-frequency preheater: phenolic resin, urea plastic, melamine (melamine), epoxy resin and other thermosetting molding materials.
