200ton 250ton 300ton 350ton 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.
