UN
Servo Hydraulic Injection Molding Machine
Globally, the plastic pallet market is expanding rapidly. The global market size reached USD 43.64 billion in 2025 and is projected to hit USD 78.53 billion by 2034, with a compound annual growth rate (CAGR) of 6.83%. As the world’s largest plastic‑pallet market, China accounts for approximately 30% of global share.
Against this market boom, production capacity becomes a core competitive asset. More pallet specifications and higher output place stricter demands for dedicated equipment. TUP has in‑depth expertise in large‑scale injection molding. Its two major series, the HS‑PLT two‑plate machine and UN‑PLT three‑plate machine, precisely cater to pallet‑production requirements across different capacities.
Featuring excellent mold compatibility, the machine adopts enlarged mold‑opening stroke and expanded mold capacity to flexibly accommodate molds of diverse specifications and substantially broaden applicable production scenarios. Meanwhile, its plasticizing system and precision‑control technology enable stable injection molding with recycled materials. While guaranteeing product quality, it helps enterprises cut raw‑material costs significantly and realize eco‑friendly sustainable production.
Furthermore, the equipment supports comprehensive whole‑plant layout planning. It can seamlessly integrate centralized feeding, automated production lines, intelligent IoT monitoring and smart warehousing systems. Extending from individual production steps to full‑process collaborative management, it facilitates manufacturers’ one‑stop transformation from traditional manufacturing to high‑efficiency smart manufacturing.
Built for High‑Volume Pallet Manufacturing
1. Extra‑large injection capacity to eliminate sink marks and deformation: The UN‑PLT pallet‑dedicated machine is equipped with extended injection stroke and high‑response injection drive units. It enables smooth, steady melt flow inside mold cavities, ensuring dense structures and stable dimensions for every part.
2. Logistics‑grade dedicated screw balancing efficiency and quality: The dedicated screw comes standard with electric pre‑plasticizing plus high‑torque oil‑cooled motor with closed‑loop control. Plasticizing efficiency rises by 30 % while energy consumption drops by 25 %, satisfying long‑hour special operating conditions for large‑size pallets.
3. Two‑section hydraulic self‑locking nozzle: Linked actions of mold‑opening / material‑accumulation / retraction greatly shorten mold‑open‑and‑close cycle time, lifting productivity by 20 %.
