Product Description
High Frequency Melamine Preheating Machine
Product Overview

The High Frequency Melamine Preheating Machine is specialized core equipment designed for modern melamine tableware compression molding production lines. Utilizing advanced high-frequency dielectric heating principles, this machine rapidly and uniformly heats melamine molding powder from the inside out, providing superior performance compared to traditional surface heating methods.

In melamine tableware manufacturing, raw melamine powder at room temperature exhibits poor flow characteristics. Direct feeding into molds for pressing often results in uneven filling, air bubbles, cracks, shrinkage marks, and other defects in finished products. By preheating melamine powder to optimal forming temperatures before hydraulic compression, our high-frequency preheating machine significantly enhances powder flowability, ensuring complete mold cavity filling and substantially reducing product defect rates.

This equipment operates independently or integrates seamlessly with melamine powder automatic weighing machines, hydraulic molding presses, edge grinding machines, and decal cutting machines to create fully automated melamine tableware production lines. It is widely adopted by melamine tableware factories for both new facility construction and existing production line upgrades.

Core Advantages
  • Internal and external uniform high-frequency heating eliminates local overheating or cold spots, ensuring consistent powder temperature batch after batch
  • Rapid heating capability significantly reduces preheating time, increasing overall production line capacity
  • Intelligent PLC + touch screen control system enables easy parameter setting for temperature, heating time, and feeding operations
  • Remarkably reduced reject rates by effectively eliminating bubbles, blisters, surface streaks, and product deformation
  • Energy-efficient high-frequency heating technology consumes less power than conventional resistance heating devices
  • Stable continuous operation performance suitable for extended industrial production cycles
  • Strong material compatibility with A1, A3, and A5 grade melamine molding compound powders
  • Compact mechanical structure design facilitates convenient installation, disassembly, and daily maintenance
  • Flexible connection design compatible with automatic weighing and feeding systems
  • Customizable configurations to match varying production output requirements for small and large melamine factories

Frequently Asked Questions
Which grades of melamine powder can this high frequency preheating machine handle?
It supports A1, A3 and A5 melamine molding compound powder, the most common raw materials for melamine tableware.
Can this machine connect with automatic weighing machine?
Yes. We can configure automatic feeding conveyor to link with melamine powder auto weighing machine, realizing automatic weighing, conveying and preheating in one continuous process.
Can the voltage be customized for different countries?
Absolutely. We can adjust the electrical system to match your local industrial voltage standard.
What is the difference between high frequency preheating and ordinary heating?
Traditional heating only warms powder surface. High frequency heating heats material from inside out, temperature distribution is much more uniform, which avoids partial over-burning and gets better molding effect.
Is this machine suitable for small melamine tableware factory?
Yes. We have multiple capacity options, including small model for small workshops and large model for mass production.
