High Frequency Melamine Preheating Machine

The High Frequency Melamine Preheating Machine is dedicated supporting equipment for melamine tableware hydraulic molding production lines. It uses high-frequency electromagnetic heating to warm MMC melamine molding powder evenly and rapidly before pressing. After preheating, the material reaches a consistent internal temperature, which effectively shortens the hydraulic pressing cycle, reduces internal stress in the finished product, improves surface gloss, and lowers the defective rate caused by bubbles, cracks, and material shortage in melamine bowls, plates, trays, and cups. It is essential equipment for efficient, high-volume melamine tableware production.

• Uniform Internal Heating: Unlike surface heating, high-frequency heating penetrates the entire melamine powder load. There is no overheated surface with a cold core, ensuring stable temperature distribution in every batch.
• Fast Heating & High Efficiency: Preheating typically takes only 30–60 seconds per batch, greatly improving hydraulic press output and supporting continuous mass production.
• Precise Time & Power Control: Equipped with a digital timer and adjustable power knob, operators can set heating parameters according to powder weight and formula, making stable production parameters easy to repeat.
• Stable & Durable Structure: Heavy-duty steel frame, built-in high-quality oscillation tube, and a reliable circuit protection system. Universal casters allow flexible movement within the workshop.
• Wide Compatibility: Compatible with all kinds of melamine molding compound and different tonnage hydraulic presses. Widely used for melamine dinnerware, children's tableware, and custom logo tableware.
