    AI Overview
    High Frequency Preheating Machine - HAN CHANG
    Melamine powder preheating equipment, primarily High-Frequency (HF) Preheating Machines (3KW-10KW+), is essential in thermoset plastic molding to rapidly heat, dry, and form melamine powder into cakes before compression molding. These machines improve fluidity, shorten casting times, eliminate water lines, and increase production efficiency, typically offering flat-electrode designs suitable for powder or granules. 
    Key Features and Benefits of Preheating Machines 
    • High-Frequency Technology: Utilizes electromagnetic waves (often
      27.12
      MHz
      ) to induce internal heat through molecular friction, heating the powder uniformly and quickly.
    • Improved Efficiency: Reduces molding cycle times (shortens casting time) and increases production yield.
    • Improved Quality: Eliminates moisture ("water lines") in finished melamine tableware and increases surface smoothness.
    • Raw Material Savings: Preheating allows for more precise material usage, saving on melamine powder, and extends the lifespan of molds.
    • Machine Types:
      • Flat Electrode Type: Ideal for powder, granules, or irregular cakes.
      • Roller Electrode Type: Suited for preformed cylindrical materials. 
    Common Specifications & Operation 
    • Power Capacities: Commonly 3KW, 5KW, 7KW, or 10KW, with options for larger production needs.
    • Operation Steps: Typically involves setting the high-frequency switch, adjusting the heating time/temperature, and placing the powder in a container for the cycle.
    • Industry Application: Crucial for melamine tableware production, bakelite powder, and electronic component manufacturing. 
    Leading manufacturers such as Shunhao Factory provide specialized high-frequency machines with over 20 years of experience, often using Japanese advanced technology components.

    People also ask
    When was melamine banned?
    June 2007
    In late October 2008, similar adulteration with melamine was discovered in eggs and possibly other foods. The source was traced to melamine being added to animal feed, despite a ban imposed in June 2007 following the scandal over pet food ingredients exported to the United States.
