This tripartite partnership brings together key players across the value chain: the forestry cooperative provides biomass by-products.

June 2025 – WOOJIN PLAIMM, South Korea’s leading manufacturer of plastic injection molding machines, has announced a collaborative initiative to advance sustainable material processing by supporting the commercialisation of an innovative eco-friendly material called CXP (Cellulose Cross-linked Polymer). In collaboration with a local forestry cooperative and a domestic CXP developer, WOOJIN PLAIMM is playing a pivotal role by developing and supplying dedicated injection molding systems optimised for the unique properties of CXP.

This tripartite partnership brings together key players across the value chain: the forestry cooperative provides biomass by-products such as wood chips and agricultural residues, the CXP developer conducts material R&D, and WOOJIN PLAIMM is responsible for manufacturing the custom-tailored injection machines required for molding CXP.

To address the specific challenges of processing CXP—such as carbonisation at relatively low melting points—WOOJIN PLAIMM has developed a dedicated injection molding solution: the DL-G5. This two-platen direct pressure machine features a custom screw design that minimises frictional heat and optimises low-temperature melt flow, significantly reducing the risk of carbonisation and gas emissions during molding.

Key technologies integrated into the DL-G5 include:

·Servo pump system for energy efficiency

·Fast dry cycle (6.0 sec at 1800 tons EUROMAP 6)

·Half-nut synchronous locking for reduced cycle time

·Modular controller with multilingual support

·Integrated inverter cabinet to minimise installation area

·Ball-bearing linear guides for reduced friction and enhanced precision

The injection unit also includes high-rigidity dual-axis rods and closed-loop backpressure control, enhancing both repeatability and responsiveness in molding CXP.

WOOJIN PLAIMM is actively preparing to expand this solution globally. Its 2 branches(Chennai, Anantapur) in Indiaare serving as key contact points for inquiries in the respective markets, with dedicated sales and support networks already in place. 

Additionally, WOOJIN PLAIMM plans to showcase live demonstrations of its CXP molding capabilities at K 2025, the world’s largest plastics and rubber trade fair, to be held in Düsseldorf, Germany, from October 8 to 15, 2025. The demonstration will feature the TE250NC, an electric two-color injection machine processing CXP resin on-site.

Founded in South Korea, WOOJIN PLAIMM operates the world’s largest single-site plastic injection molding machine production facility and conducts global business through 42 branches in 27 countries. Leveraging this network, the company exports its solutions worldwide, supporting diverse customer needs across continents. Its product range includes hydraulic, electric, hybrid, horizontal, vertical, and tie-barless injection machines, along with solutions for foam injection and customised applications.

By aligning cutting-edge engineering with environmentally responsible material innovation, WOOJIN PLAIMM is positioning itself as a strategic partner for the future of sustainable manufacturing.
