In the global supply chain, eco-friendly and export-ready logistics packaging has become a strategic priority. Aug, 2025, ZK Hydraulic achieved a significant milestone by completing the production, rigorous factory acceptance testing (FAT), and dispatch of 12 complete sets of heavy-duty presswood pallet machines to an industrial client in Vietnam.
The specific delivery quantities are as follows:
- 9 units of the ZK-1600 Standard Pallet Press
- 2 units of the ZK-3000 PV Molded Pallet Press
- 1 unit of the ZK-D1600 Flat-Surface Pallet Press
This comprehensive delivery is designed to help the client utilize abundant local timber and agricultural residues, transforming low-value biomass into high-strength, export-grade ISPM-15 compliant molded pallets.
Project Background & Market Opportunity in Vietnam
As Southeast Asia’s manufacturing and photovoltaic (PV) export sectors surge, Vietnam’s logistics industry faces two critical challenges:
- Rising Demand for Compliant Pallets: Photovoltaic pallets measure about 2.4 × 1.3 m. Traditional solid-wood pallets used for PV products exported to North America, Japan, and Europe are complex and costly to manufacture and require fumigation. In contrast, molded wood-chip pallets can be custom-sized, produce one pallet in about 4 minutes, are fumigation-free and fully ISPM-15 compliant, and cost about 30% less than traditional pallets—making them an ideal replacement.
- Abundant Biomass Resources: Vietnam boasts vast wood processing waste—including coconut waste, rice husk, acacia, eucalyptus wood chips, sawdust, rubberwood remnants, and agricultural biomass.
Green Pallet partnered with ZK Hydraulic to establish one of Vietnam’s largest automated molded wood pallet production hubs, aiming to replace costly solid timber pallets with sustainable compressed wood alternatives.
Machine Configuration & Technical Highlights
Delivering 12 hydraulic compression units simultaneously requires exceptional manufacturing capacity and strict quality control. The delivery package consisted of specialized configurations engineered for high-tonnage stability, precise temperature control, and multi-shift industrial reliability:
| Parameter / Configuration | Technical Specification |
| Delivered Machine Models | ZK-1600 (Standard), ZK-D1600 (Flat surface pallet), ZK-3000 (Heavy-Duty & PV Solar Pallets) |
| Total Units Shipped | 12 Complete Compression Molding Presses + Auxiliary Feeding/Dosing Units |
| Nominal Clamping Force | 1,600 Tons – 3,000 Tons |
| Heating Method | High-efficiency Thermal Oil Circulation System (Uniform heating across upper & lower platens) |
| Pallet Formats Produced | 1200×1000 mm (Standard Euro/ISO), 1100×1100 mm (Container Size), and 2500×1300 mm Extra-Large Solar Pallets |
| Control Architecture | Siemens PLC with high-precision touch HMI & proportional pressure regulation |
| Cycle Time & Capacity | 15-20 pallets per hour per machine (Average 180–200 s hot-pressing cycle) |
Key Engineering Features of the Delivered Line:
- One-Piece Cast Steel & Rigid Frame Design: Engineered with finite element analysis (FEA) to eliminate frame deformation under prolonged 1600T–3000T clamping cycles.
- Synchronous Multi-Cylinder Pressing: Ensures an even pressing tolerance across the entire mold platen, preventing surface density variances and pallet deformation.
- Optimized Dewatering and Venting Mechanics: Multi-stage exhaust cycles allow steam and moisture to escape quickly without causing core blistering or cracking during curing.
Raw Material Testing & MDI Adhesive System
Prior to delivery, the Green Pallet acceptance team visited the site to witness the trial run firsthand.
- Fiber Preparation: Local Vietnamese acacia and mixed hardwood chips were crushed into 5–15 mm wood shavings and dried to an optimal moisture content of 13% – 17%.
- Eco-Friendly Bonding: The line was calibrated using specialized environmental MDI (Methylene Diphenyl Diisocyanate) resin instead of traditional urea-formaldehyde (UF). This formulation yields pallets with zero free formaldehyde emissions, superior waterproof performance, and exceptional bending stiffness under humid tropical conditions.
The client maintained extremely strict standards throughout the acceptance process. After multiple rounds of testing, they were fully satisfied and officially signed off to accept the shipment.
Factory Acceptance Testing (FAT) & Shipping Logistics
Before packing and container loading, each of the 12 presses underwent comprehensive trial runs:
- 72-Hour Continuous Hydraulic Pressure Holding Test: Verifying valve block response, oil temperature stability, and seal integrity.
- Pallet Dimensional & Deflection Inspection: Full test moldings were performed to verify static load capacities (>2,500 kg) and dynamic loads (>1,200 kg).
- Secure Ocean Freight Packaging: The massive press bodies, power units, electrical cabinets, and precision molds were coated with rust-inhibitive wax, vacuum-sealed with multi-layer barrier foil, and secured onto heavy flat-rack containers to withstand sea transport to Vietnam.
On-Site Commissioning and Customer Value
Upon arrival at the port in Vietnam, our dedicated installation engineers will provide full on-site guidance, including foundation verification, hydraulic system hookup, PLC synchronization, mold installation, and operational training for the local workforce.
Once fully operational, this 12-press production facility will boast an annual capacity exceeding 1,000,000 molded presswood pallets, giving our customer a commanding market position in sustainable packaging across Southeast Asia.
