Explore our primary machinery portfolio engineered for the strict requirements of Nordic manufacturing, blending energy efficiency with heavy-duty output performance.
Denmark stands as a global beacon for green transition, ecological compatibility, and high-tech manufacturing. Under the governance of the Danish Environmental Protection Agency (Miljøstyrelsen) and European Union green directives, the Danish plastics sector is transitioning rapidly towards a closed-loop economy. This systemic shift has completely redefined the technological expectations placed on plastic sheet extrusion machines.
Today, Danish processors must navigate strict constraints concerning carbon footprints, energy conservation metrics, and the mandatory inclusion of Post-Consumer Recycled (PCR) polymers or bio-based resins such as Polylactic Acid (PLA). Traditional single-material machines are no longer competitive. Sourcing requirements now prioritize co-extrusion technology, enabling multi-layer designs where recycled materials are nested safely between virgin barriers, ensuring both structural integrity and strict hygiene standards for packaging.
Danish enterprises are under strict regulatory frameworks to achieve carbon neutrality. Implementing high-efficiency Siemens PLC system controls, infrared ceramic heating bands, and high L/D ratio screw designs drastically reduces raw energy utilization per kilogram of extruded polymer.
Our plastic sheet extrusion machinery integrates specialized barrier screw geometry optimized for processing sensitive materials such as PLA, PET, PP, and PS. With integrated gravimetric dosing units, local operators in Denmark can transition from 100% virgin polymer to high-ratio recycled material feeds with minimal downtime, ensuring optimal viscosity tracking and melt temperature stability.
To align with Danish advanced manufacturing standards, our systems include Modbus, Profinet, and OPC UA protocols. This enables real-time reporting of throughput speed, thickness tolerance, and thermal consumption metrics directly to centralized ERP databases.
All machinery structures comply fully with the European Machinery Directive 2006/42/EC. We utilize premium electrical components, high-integrity mechanical shielding, and automated pressure relief emergency mechanisms to guarantee operator safety in Scandinavian factories.
We engineer heavy-duty industrial solutions that integrate energy conservation, micro-precision sheet thickness control, and continuous material processing.
Our feedblock designs allow up to 3, 5, or 7-layer configurations (A/B/A, A/B/C/B/A). This facilitates the use of internal recycled layers while outer skin layers preserve aesthetic finish, chemical resistance, and food-grade hygiene certifications.
Advanced T-die tooling with dynamic lip adjustment ensures cross-web thickness variance under ±1%. Our systems can be paired with beta/gamma transmission sensors for closed-loop automatic die bolt regulations.
Water-cooled feed throats combined with insulated induction heating bands allow for precise thermal profiling. High venting capacity ensures volatile elements are removed, yielding clear, bubble-free sheet structures.
Machinery manufacturing requires highly specialized engineering expertise. Technological depth is our defining feature at Wenzhou Yicai Machinery Technology Co., LTD. (formerly known as Ruian Seven Star Machinery since our establishment in 2010, and rebranded in 2022). Our operations require advanced engineering capabilities, encompassing precision mechanical layout design, automated PLC programming, and high-tolerance metal machining.
Modern extrusion systems require reliable structural stability to withstand high mechanical forces. We manufacture complex assemblies involving specialized steel grades, precise welding alignments, and high-torque gearboxes. Our equipment serves diverse global markets, meeting clean energy and environmental conservation requirements while supporting high production throughput.
Headquartered in Zhejiang, one of East China's leading manufacturing provinces, our facilities feature modern production lines, inspection equipment, and dedicated technical development centers.
Our commitment goes beyond manufacturing. We provide comprehensive operational consulting to help clients select the right raw material formulations, set up efficient production lines, and minimize energy consumption.
Balancing competitive manufacturing costs with European quality, safety, and operational standards.
Purchasing sheet extrusion lines from qualified Chinese manufacturers allows Danish operators to optimize initial investments. The capital saved can be redirected toward factory automation, local environmental compliance, and business development.
We provide end-to-end lines spanning gravimetric dosing, primary extrusion, multi-roll calendering, online thickness checking, cooling towers, and winding machinery, eliminating integration issues on the factory floor.
Our machines are equipped with secure remote access modules. This allows our design engineers to perform remote diagnostics, update software, and debug systems anywhere in Denmark, reducing down-time.
Our extruders process PP, PS, PET, PE, and PLA into high-grade sheets suitable for a wide range of industrial applications.
High-clarity PET/PLA sheets engineered for thermoformed drinking cups, lids, and blister packaging.
Multi-layer barrier sheets (PP/EVOH/PP) designed to preserve freshness in modified atmosphere packaging.
100% biodegradable PLA sheet lines developed for eco-conscious food service and consumer packaging.
Thicker polyolefin sheets used in logistics trays, agricultural containers, and industrial liners.
Answers to key operational, regulatory, and mechanical questions for engineers and purchasing managers.
Our extruders use dedicated screw designs with optimized L/D ratios (up to 33:1 or 35:1) and specialized mixing zones. This ensures consistent shear forces and homogeneous melt temperatures. When paired with high-performance melt pumps and continuous back-flush screen changers, contaminants are filtered out, and raw materials feed smoothly without thickness variations.
We offer complete installation and commissioning support. Our technicians assist with factory layout planning, electrical connections, system startup, and team training. For ongoing operations, we provide remote PLC diagnostics alongside fast spare parts dispatch from our central supply chain centers.
Every machinery line is designed and built to meet EU directives. This includes CE certification, electromagnetic compatibility standards (EMC), and emergency stop networks. High-voltage cabinets are constructed with premium switchgear (such as Siemens or Schneider) to ensure reliable operation in Denmark.
Lead times generally range between 60 to 90 days, depending on system complexity (e.g., customized multi-layer co-extrusion lines). Machinery is fully assembled and test-run with raw materials at our facility prior to shipment, and customers receive video verification before packing.
