Hydraulic Compression Molding Presses for Melamine Dinnerware
250-400 Ton hydraulic presses delivering mirror-finish melamine plates, bowls & trays with ≤45s cycle time, EU-compliant safety & IoT remote monitoring capabilities.
Press Purpose & Market Advantages
These four-column servo-hydraulic presses are engineered exclusively for melamine-formaldehyde tableware production. The 250 ton model targets start-ups and sample rooms (1-2 cavities), while the 300 ton, 350 ton and 400 ton versions serve high-volume factories running 4-12 cavity molds on single or double-color production lines.
- ≤0.05 mm platen parallelism keeps plate warpage <0.3 mm, eliminating post-mold polishing in 80% of parts
- Servo pump + accumulator circuit reduces power consumption by 28% and noise to <68 dB(A)
- CE-certified two-hand control, light curtains, overload & die-protection valves - accepted by Amazon, IKEA, Walmart suppliers
- IoT gateway exports OEE, cycle counters & fault codes to ERP for instant ISO-9001 documentation
Machine Range Specifications
*Based on 8″ dinner plate; exact number depends on shrinkage & gating design
