Large Size Paper Plate Making Machine
The Jiuyimachine Large Size Paper Plate Making Machine converts heavy-gauge paperboard (250–900 GSM) into 9-inch to 16-inch large-format tableware. Designed around a reinforced structural frame and a high-tonnage hydraulic forming system, it delivers sustained pressure to eliminate rim wrinkling and structural cracking during high-speed deep-draw cycles.
Description
The Jiuyimachine Large Size Paper Plate Making Machine converts heavy-gauge paperboard (250–900 GSM) into 9-inch to 16-inch large-format tableware. Designed around a reinforced structural frame and a high-tonnage hydraulic forming system, it delivers sustained pressure to eliminate rim wrinkling and structural cracking during high-speed deep-draw cycles.
The production workflow integrates automated vacuum paper feeding, multi-zone thermal pressing, edge trimming, and automated stack-counting, engineered for continuous three-shift operation.
Product Advantages
High-Tonnage Hydraulic Drive: Dual-circuit hydraulic power pack delivers up to 10 tons of clamping force, ensuring zero edge-splitting on deep-walled plates (>30mm depth).
Thermal Zone Calibration: Independent cartridge heaters managed by solid-state PID controllers maintain thermal variance within ±1.5°C for reliable activation of aqueous and PE barrier coatings.
Rapid Tool Interchangeability: Quick-clamp sub-plates and centralized pneumatic release mechanisms reduce mold swap times between different diameters to under 35 minutes.
Low Scrap Architecture: Precision photoelectric paper-break sensors and mechanical index guides halt cycles instantly upon feed misalignment, keeping material wastage below 0.5%.

FAQ
Q: What is the maximum paper thickness the hydraulic system can compress?
A: Up to 900 GSM, equivalent to heavy multi-ply corrugated liner or dense bagasse composite board, provided raw material moisture remains below 8%.
Q: How long does a complete mold changeover take?
A: An experienced technician can execute a full tool swap-including upper/lower dies and PID recalibration-in 30 to 40 minutes using standard hand tools.
Q: Is the equipment compatible with plastic-free, aqueous-coated paperboards?
A: Yes. Multi-zone PID temperature controllers deliver the precise thermal profiling required to seal water-based dispersion coatings without blistering.
Q: What utilities must be installed prior to machine delivery?
A: A stable 380V/480V 3-phase power feed, an air compressor line supplying at least 0.8 MPa of dry, filtered air, and a minimum working area of 4.5 m × 3.5 m.
Q: How are custom-shaped molds engineered?
A: Clients supply 2D/3D design files (STEP/IGES format). Our engineering team runs finite element stress simulations before cutting tool steel profiles on CNC wire-cut machines.
