Melamine Preheating Machine

The Melamine Preheating Machine, also known as a melamine preheater, is essential auxiliary equipment for a melamine tableware production line. It is specially designed to preheat melamine moulding compound (MMC powder) before hydraulic compression molding. Through uniform heating, it shortens the molding curing time, reduces bubbles, cracks, and the defective rate, and improves the surface gloss of finished melamine ware. This preheater works perfectly with melamine hydraulic press machines, melamine moulds, and automatic weighing machines, greatly boosting production efficiency for melamine dinnerware factories. We offer both electric heating and high-frequency heating types for your selection.

• Uniform and Stable Heating: A precise temperature control system ensures even heating of melamine powder with no local overheating or insufficient heating, delivering a consistent softening state of raw material for every batch.
• Intelligent Temperature Control: A digital temperature controller makes setting and displaying temperature easy. A temperature alarm function activates when abnormalities occur, convenient for workers to operate.
• Shortened Molding Cycle: Preheated MMC powder requires less curing time inside the mould, effectively improving machine output and reducing energy consumption of the hydraulic press.
• Lower Defect Rate: Reduces common defects such as air bubbles, flow marks, shortage, and white spots on melamine products, improving yield and finished surface quality.
• Wide Compatibility: Suitable for A1/A3/A5 grade melamine molding powder and matches all standard melamine compression moulds and hydraulic molding presses.
• Stable and Durable Structure: A heavy-duty frame and heat insulation layer reduce heat loss. Heat-resistant components ensure a long service life and low maintenance cost.
• Customized Specification Support: We can customize cavity quantity, heating power, and feeding method according to the customer's mould size and production capacity requirements.

The melamine preheating machine transfers heat evenly to the weighed melamine raw powder. Under the set temperature, the powder turns soft and plastic preliminarily without full curing. After preheating, workers take out the material and place it into the hot mould of the hydraulic press. Under high temperature and high pressure in the mould, the thermosetting reaction proceeds quickly. Preheating removes partial moisture inside the powder and prevents gas from being trapped during compression.

1. Preheat the machine before feeding powder, and wait until the temperature reaches the set value.
2. Do not overheat the melamine powder; otherwise, the powder will cure in advance and cause waste.
3. Keep the heating cavity clean and remove residual powder regularly to prevent carbonization.
4. Check the temperature sensor and heating element regularly to ensure stable running.
5. Keep the equipment in a dry environment and avoid moisture entering the electrical control box.

The main machine is packed in a wooden case for sea shipment. Pallet packing together with the hydraulic press and mould is supported. We support FOB, CIF, and other trade terms.

We provide an installation guide, operation manual, and parameter recommendations. Our engineers offer remote technical support for temperature and time setting. Spare parts supply is available at favorable prices after the warranty period.
