400 TON Melamine Crockery Making Machine For Tableware Pressing

Dongxin Melamine Crockery Machine is a heavy-duty automatic hydraulic compression molding press specifically engineered for manufacturing high-quality melamine tableware. Available in 200-ton, 250-ton, 300-ton, and 350-ton clamping force configurations, this PLC-controlled pressing machine transforms melamine molding compound (MMC), urea molding compound (UMC), and bamboo fiber materials into durable, food-safe dinnerware including plates, bowls, cups, spoons, and trays.

With Taiwan-upgraded hydraulic technology and precision-engineered casting components, Dongxin machines deliver stable vertical pressure up to 210 kg/cm², ensuring perfect mold filling and eliminating common defects like insufficient curing, burrs, or dimensional inconsistencies.

Constructed from Grade 50 nodular cast iron (ductile iron) with heat-treated tension columns (Ø90mm-Ø120mm), the Dongxin press frame withstands high off-center loads without deformation. This heavy-duty construction ensures 15+ years service life, significantly outperforming standard cast iron alternatives.

• 200-250 ton models: High/low-pressure loop system with smooth, noise-free operation
• 300-350 ton models: Yuken double proportional valve (Japan) enabling infinite adjustment of speed and pressure during pressing cycle
• Maximum air release frequency: Up to 99 times for complete degassing, preventing bubbles and ensuring dense, strong tableware

• Delta PLC options with 7-inch color touchscreen
• 100+ product formulas storage capacity for quick mold changeover
• Three-level permission management: Operator, Engineer, Administrator
• Real-time monitoring: Temperature, pressure, cycle time, production count
• Fault diagnosis: Automatic alarm system with troubleshooting guidance

• Electric heating plates made from 45# steel with chrome plating
• Temperature range: Room temperature to 180°C (adjustable per material specification)
• Uniform heat distribution: Prevents hot spots that cause warping or incomplete curing
• Fast preheating: Reduces startup time and energy consumption

• Photoelectric safety grating: Protects operators during mold closing
• Emergency stop buttons: Multiple locations for immediate shutdown
• Mold protection: Slow-speed mold closing initially, then high-speed synchronization to prevent damage
• Automatic ejection: Ensures smooth product removal without manual intervention
