Key Features of the 2200-Ton Molded Pallet Press Machine (ZK-2200)
Manufactured by ZK Hydraulic, an experienced provider of compression molding solutions, the ZK-2200 Heavy-Duty Presswood Pallet Machine is engineered for high-density, high-output industrial pallet manufacturing. Combining robust mechanical engineering with an energy-efficient servo hydraulic system, this machine delivers high pressing accuracy, reduced energy consumption, and reliable performance for continuous industrial production.
1. Heavy-Duty Clamping Force & Large Working Bed
- 22,000 kN (2,200 Metric Tons) Nominal Force: Provides powerful and uniform compression for producing high-density molded pallets with excellent structural strength and dimensional stability. See how higher pressure produces stronger molded pallets.
- Spacious 2,200 mm × 1,800 mm Platen Area: The large working table accommodates a wide range of standard and customized pallet sizes and is compatible with single-cavity or multi-cavity pallet molds for nine-feet pallets, rackable presswood pallets, and solar panel pallets.
- Rigid Four-Column Hydraulic Frame: Constructed with high-strength structural steel, the machine features an overall height of approximately 5,600 mm and a clearance of approximately 2,200 mm. The rigid frame is designed to minimize deflection under full pressing force, helping maintain uniform pressure, consistent pallet thickness, and high dimensional stability across the entire mold.
2. Advanced 55 kW Servo-Driven Hydraulic System
- Energy-Efficient Servo Technology: Powered by a high-performance 55 kW Yiyueteng servo motor and INVT servo drive, the system optimizes hydraulic power consumption and can significantly reduce energy consumption compared with conventional fixed-speed hydraulic systems.
- Japan WOTE High-Pressure Gear Pump: Provides stable, high-pressure hydraulic oil flow at system pressures of up to 25 MPa, while maintaining low operating noise and reliable long-term performance.
- Reliable Luhai / Luwei Hydraulic Control: Equipped with industrial-grade Shandong Luhai/Luwei hydraulic valve blocks, the hydraulic system provides precise pressure regulation and stable pressure-holding performance throughout the molding cycle.
- Taiwan DZ (Dingji) High-End Seals: High-quality sealing components help prevent internal and external hydraulic leakage and support reliable operation during continuous multi-shift production.
3. Optimized Multi-Speed Compression Cycle
- Fast Approach Speed – 140 mm/s: The slide approaches the mold at high speed, reducing non-productive cycle time and improving overall production efficiency.
- Micro-Adjustable Pressing Speed – 3–5 mm/s: The controlled pressing speed provides smooth and stable compression, allowing resin and wood fibers or composite raw materials to distribute more evenly while helping trapped air escape, reducing the risk of cracks, voids, and delamination.
- Rapid Return Speed – 140 mm/s: The slide returns quickly after the molding cycle, shortening the overall cycle time and preparing the machine for the next production cycle.
- Wide Stroke & Daylight: The machine features a 700 mm main cylinder stroke, a maximum daylight opening of 1,300 mm, and a minimum shut height of 600 mm, providing sufficient space for mold installation, thermal expansion, heated molds, and automatic demolding systems.

4. Integrated 400 kN Hydraulic Ejection System
- Powerful Mold Demolding: Equipped with a built-in bottom ejector cylinder delivering up to 400 kN of ejection force with a 200 mm stroke, the system provides powerful and controlled demolding for deep-cavity pallet molds.
- Automation-Ready: The hydraulic ejection system can be synchronized with robotic take-out arms, automatic conveyors, and pallet stacking systems, making it suitable for fully automated presswood pallet production lines.
5. Intelligent PLC Automation & International Electrical Standards
- Smart PLC & HMI Touchscreen: The centralized PLC control system allows operators to monitor and adjust key production parameters, including pressing pressure, pressing speed, cycle time, heating temperature, stroke limits, and pressure-holding time.
- Industrial-Grade Electrical Components: The electrical control cabinet incorporates Schneider Electric and CHNT components, providing reliable machine control, convenient maintenance, and stable operation in demanding industrial environments.
6. Multi-Material Molding Versatility
- While primarily designed for compressed sawdust, wood chips, and other biomass materials used in molded presswood pallet production, the 2,200-ton pressing capacity and large working table also provide flexibility for selected compression molding applications, including recycled plastic pallet production, molded cable drums, industrial packaging blocks, and other custom molded products.
