350-Ton Melamine Tableware Moulding Machine for Bowl Plate Direct Factory Manufacturer

Focus on Efficient Monochrome Molding: The machine is designed exclusively for Monochrome production, capable of stably processing Monochrome melamine powder raw materials such as pure white and pure black. Through precise powder filling control and high-pressure clamping, it ensures uniform color and no color difference of Monochrome tableware, meeting the standardized production needs of basic tableware.

High-Precision Temperature Control and Pressure Regulation: Equipped with an advanced temperature control system, the temperature uniformity error of the heating plate is ≤ ±2℃, which can accurately match the curing temperature of melamine powder (150-170℃). The 350-ton clamping force and adjustable injection pressure (0-50MPa) can adapt to the production of Monochrome tableware with different thicknesses (such as thin spoons and thick-walled plates), avoiding defects like air bubbles and material shortage, and ensuring the product hardness meets the standard (Rockwell hardness M90+).

Simplified Automatic Operation: Equipped with a basic PLC control system, it presets core parameters including powder filling amount, mold clamping time, pressure holding duration, and cooling temperature, realizing the full-process automation of "powder filling - mold clamping and pressurization - pressure holding and curing - cooling and demolding". There are few parameter adjustment items, making it easy for workers to master, reducing manual operation errors, and improving production stability.

Rapid Cooling and Demolding: Built-in with dual cooling systems (water cooling + air cooling), it can cool the molded products to below 80℃ within 30-60 seconds, shortening the production cycle of Monochrome tableware. Equipped with an ejection-type demolding structure, the demolding force is uniform, avoiding deformation or scratching of finished products and ensuring the appearance integrity of tableware.

Powder Filling: Monochrome melamine powder (e.g., pure white, pure black) is evenly filled into the cavity of the Monochrome mold through the machine's automatic powder filling system. The system precisely controls the powder filling amount to avoid waste caused by excessive powder or product material shortage due to insufficient powder.

Mold Clamping and Pressurization: The hydraulic system is activated, and the mold is quickly closed with a 350-ton clamping force. At the same time, the heating plate is heated to the preset curing temperature (150-170℃), enabling the Monochrome melamine powder to be initially molded and conform to the mold shape.

Pressure Holding and Curing: Maintain the injection pressure (20-30MPa) and curing temperature for 30-60 seconds to ensure complete cross-linking of the Monochrome melamine resin, improving the hardness and durability of the tableware and preventing cracking and deformation during subsequent use.

Cooling and Demolding: The cooling system is automatically activated, and the mold and product are cooled to below 80℃ through the synergy of water cooling and air cooling. After the product is stabilized, the ejection mechanism smoothly pushes out the Monochrome finished product to avoid product damage.

Post-Processing: Manually or by automated equipment, remove the burrs on the edge of the finished product. After quality inspection (appearance: no scratches, no color difference; size; safety: formaldehyde emission testing), package and store the products in the warehouse.

Advantages:

1. Low cost: The equipment price is only 50-70% of that of multi-color machines.

2. Simple operation: Few parameter adjustments, easy for workers to master.

3. Convenient maintenance: Simple structure, low failure rate.

Disadvantages:

1. Poor flexibility: Unable to produce multi-color or gradient effects.

2. Limited efficiency: Frequent cleaning is required for Monochrome powder filling, and changing colors takes time.
