WOOJIN PLAIMM Develops Dedicated Injection Molding Machine for Eco-Friendly CXP Material through Strategic Partnership

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 commercialization 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 optimized for the unique properties of CXP.

A Sustainable Partnership for a Greener Future

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.

DL-G5: A Machine Tailored for CXP
To address the specific challenges of processing CXP—such as carbonization 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 minimizes frictional heat and optimizes lowtemperature melt flow, significantly reducing the risk of carbonization 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 minimize installation area
• Ball-bearing linear guides for reduced friction and enhanced precisionThe injection unit also includes high-rigidity dual-axis rods and closed-loop backpressure control, enhancing
  both repeatability and responsiveness in molding CXP.

  Global Market Strategy and K 2025 Participation
  
  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.
