27.12 MHz High Frequency Melamine Preheating Machine with 3-Stage Voltage Control and Stainless Steel Construction

The High Frequency Melamine Moulding Compound Preheating Machine is designed for rapid material preparation before hydraulic compression molding in melamine and urea tableware production. Using 27.12 MHz high-frequency heating technology, the machine heats molding compound quickly before the material enters the hydraulic press.

• 5KW
• 7KW
• 10KW

• Melamine Moulding Compound (MMC)
• Urea Moulding Compound (UMC)
• Thermosetting Moulding Compound

The machine uses high-frequency electromagnetic heating technology operating at 27.12 MHz. Instead of relying only on conventional surface heating, high-frequency energy is used to rapidly heat suitable molding material before compression.

Reference heating performance: Up to approximately 110°C within 60 seconds. Actual heating results depend on material type, weight, power configuration, initial temperature, and preheating settings.

The machine incorporates a 3-stage voltage switching system to provide greater flexibility during material heating. Operators can select suitable operating conditions according to material quantity, molding compound type, product size, and required heating level.

Different production requirements can be matched with different machine power levels (5KW, 7KW, 10KW), allowing customers to select a preheater according to their molding material quantity and production requirements.

Heating conditions can be adjusted according to different molding compounds and tableware specifications, making it particularly useful when switching between small bowls, dinner plates, deep bowls, large trays, and serving ware.

The machine incorporates stainless steel construction for practical industrial use, providing clean appearance, easy maintenance, industrial durability, and convenient workshop cleaning.

Typical workflow: Powder Weighing → High Frequency Preheating → Hydraulic Compression Molding. Preheating prepares the molding compound before it enters the press, supporting an efficient and repeatable production sequence.

DONGXIN provides different preheating machine configurations according to the customer's raw material, tableware specifications and production capacity.

Available power options: 5KW, 7KW, 10KW. Machine power can be selected according to material weight, product dimensions, required heating speed, and production capacity.

Different molding compounds may require different preheating conditions. The machine can be configured according to MMC/UMC, product weight, mold size, and pressing cycle requirements.

Electrical specifications can be matched according to the destination market and factory power supply. Customers should provide voltage, frequency, phase, and factory power conditions before production.

The machine can be configured according to the customer's main products including plates, bowls, cups, trays, serving ware, and dinnerware sets.

Recommended equipment combination: Automatic Weighing Machine → High Frequency Preheating Machine → Hydraulic Melamine Press → Automatic Grinding Machine. Customized melamine tableware molds can also be supplied according to product drawings or samples.

Suitable for preheating molding material used for dinner plates, square plates, restaurant plates, serving plates, and decorative plates.

Suitable for rice bowls, soup bowls, deep bowls, serving bowls, and restaurant bowls.

Applicable to molding material preparation for serving trays, food trays, hotel trays, cafeteria trays, and customized trays.

The preheater can also be used for cups, small bowls, small plates, and tableware accessories.

In addition to melamine molding compound, the machine can be used with suitable urea-based thermosetting molding materials for UMC products, urea resin tableware, and thermosetting molded products.

The adjustable preheating system is suitable for factories manufacturing several product categories including plates, bowls, cups, trays, and serving ware.

The manufacturing process includes production requirement confirmation, mechanical structure preparation, high frequency system installation, electrical control integration, heating system debugging, material trial test, continuous operation test, and final inspection.

Comprehensive inspection procedures include high frequency system inspection, electrical system inspection, mechanical inspection, and final running test to confirm stable operation.

Standard packaging includes wooden frame with additional export protection such as protective film, moisture protection, electrical component protection, and reinforced export packaging.

Recommended production process: Raw Material → Automatic Weighing → High Frequency Preheating → Hydraulic Press Molding → Automatic Edge Grinding → Quality Inspection → Packaging.

Preheating prepares the thermosetting molding compound before it enters the hydraulic press. It can help shorten the material preparation stage and support a more efficient compression molding process.

Available configurations include 5KW, 7KW, and 10KW. The appropriate power level should be selected according to material weight, tableware size and production requirements.

The machine is mainly intended for suitable thermosetting molding compounds such as Melamine Moulding Compound (MMC) and Urea Moulding Compound (UMC).

Yes. The machine can be used for different tableware products by adjusting the heating conditions according to material quantity and product requirements.

Yes. DONGXIN can provide supporting equipment including automatic weighing machines, hydraulic melamine press machines, melamine tableware molds, and automatic grinding machines.
