Premium industrial extrusion, advanced thermoforming, and highly precise printing systems engineered for global manufacturing demands.
Technological transformation and industrial demand in modern packaging and raw material synthesis.
Modern plastics manufacturing is undergoing a paradigm shift driven by the twin imperatives of resource efficiency and strict sustainability targets. At the center of this transformation is the high-speed plastic extruder. Unlike traditional extrusion systems which rely primarily on barrel length and slower rotations to build pressure and melt materials, today’s high-speed co-extrusion technology utilizes optimized screw design, highly dynamic thermal profiles, and closed-loop control to significantly boost outputs while dramatically reducing specific energy consumption.
In high-performance food and medical packaging, multi-layer co-extrusion has become the industry benchmark. Extruders are no longer just melting plastic; they are compound-processing micro-layers of functional resins such as PP, PS, PET, EVOH, and PLA. By using 3, 5, or 7-layer feedblocks, manufacturers can minimize the raw material footprint while maximizing oxygen barriers, mechanical stiffness, and optical clarity. Implementing an ODM High Speed Extruder Factory solution ensures that variables such as shear rates, melt flow indexes (MFI), and thermal stresses are precisely balanced, eliminating defects and ensuring consistent quality.
By using multiple extruders feeding into a single co-extrusion block, manufacturers can layer materials with different properties. For instance, putting a thin barrier layer of EVOH between two robust food-grade polypropylene layers extends product shelf-life and maintains absolute purity without excessively increasing production costs.
Global regulatory pressure and shifting consumer sentiment are pushing industrial manufacturers to design for the circular economy. The extrusion industry is addressing this in two key areas: the processing of biodegradable bio-polymers like Polylactic Acid (PLA) and the incorporation of high percentages of Post-Consumer Recycled (PCR) flakes. Processing PLA requires exact thermal profiling and dehumidification systems to prevent hydrolysis, a degradation process that compromises the molecular weight of the polymer. Standard extruders struggle with these sensitive materials; however, Wenzhou Yicai Machinery's high-speed extruders feature customized screw profiles and precise ventilation configurations to maintain polymer integrity at high throughputs.

Our expert technical sales team provides comprehensive analysis on materials, product dimensions, and ROI to help select the ideal machinery setup.
Founded in 2010 (previously widely recognized as "Ruian Seven Star Machinery") and officially rebranding to "Wenzhou Yicai Machinery Technology Co., LTD." in 2022, we have focused on manufacturing plastic extrusion and thermoforming lines. Located in East China's Zhejiang Province, Wenzhou Yicai leverages the regional machinery manufacturing cluster to combine cost-effective manufacturing with cutting-edge machinery design.
We believe in high-quality hardware integration. Our extruders utilize barrels and screws crafted from high-grade alloy steel (38CrMoAlA), treated with gas nitriding and carbide spray coatings to ensure exceptional wear resistance against abrasive polymers. Temperature control is managed via multi-zone ceramic heating elements paired with highly effective fan cooling units, ensuring thermal deviation stays within ±1°C.
By integrating well-known international components—such as Siemens PLC systems, ABB variable frequency drives, Omron temperature controllers, and premium gearboxes—we reduce operational risks, simplify maintenance, and ensure compatibility with standard factory networks worldwide.
Wenzhou Yicai operates under a strict ISO9001:2015 quality management system. The factory flow is managed via automated scheduling, ensuring that every step, from welding to fine machining of internal parts, is fully logged and verified. Before shipment, every machine runs continuously under load for a minimum of 48 hours to guarantee stable mechanical and electrical operations.
In addition to machinery design, we focus heavily on the auxiliary processes. High-precision melt pumps, automatic screen changers (both hydraulic and continuous non-stop types), and advanced T-dies ensure flat and consistent sheet gauge control. For downstream applications, our calendar rolls (whether in vertical, oblique, or horizontal orientation) feature independent motor controls and interior water-cooling channels to ensure uniform sheet solidification.
Unlocking unparalleled cost efficiencies, raw material access, and manufacturing speed.
Zhejiang Province is home to one of the world's most complete mechanical component ecosystems. From casting and heat treatment to specialized motor manufacturing, raw materials are sourced locally, reducing transport time and component assembly overheads.
By integrating local specialized suppliers, Wenzhou Yicai can assemble and customize complex extrusion and thermoforming lines in a fraction of the time required by European or American competitors, accelerating your time-to-market.
Lower overheads allow us to reinvest in premium components (e.g. Siemens PLCs, Omron modules) while keeping equipment costs competitive, offering high returns on investment (ROI) for global producers.
For international buyers, importing machinery from China requires confidence in safety compliance and mechanical design. Wenzhou Yicai builds all export machines to meet stringent CE regulations (safety and low-voltage directives) and UL requirements. Our electrical cabinets feature cleanly labeled wire tracks and safety interlocks. We also design machinery with safe access platforms and emergency-stop circuits, ensuring compliance with OSHA and European health and safety regulations.

Navigating total cost of ownership (TCO), material efficiency, and long-term service contracts.
Procuring capital-intensive equipment like high-speed extrusion lines is a strategic decision for packaging converters. Beyond initial pricing, modern procurement teams evaluate machinery on Total Cost of Ownership (TCO) over a 10 to 15-year lifecycle. The key pillars of our TCO optimization strategy are:
Additionally, our online edge-material online crushers (like the *China Sheet Machine Edge Material Online Crusher* listed in our products) recycle side-trims and scrap directly back into the feed throat of the extruder, helping to maintain close to zero material waste.
Combining the extrusion line with our multi-station servo thermoforming systems allows for direct, in-line thermoforming. By processing the hot, freshly extruded plastic sheet directly before it cools down completely, you save up to 40% of the energy normally spent reheating sheets, while also cutting down on space, storage, and handling costs.
The manufacturing process at Wenzhou Yicai requires experienced engineers and precision assembly. Below are snapshots showing our factory layout, testing areas, and mechanical assemblies.
Clear answers to complex technical questions on co-extrusion, materials, maintenance, and support.
Different polymers require specific screw designs to ensure proper melting and blending. Polypropylene (PP) needs barrier flights and mixing sections to manage shear, while amorphous Polyethylene Terephthalate (PET) requires a screw with a low-compression ratio and venting zones to release volatiles. Polylactic Acid (PLA) is shear-sensitive and requires deep flight depths and low-friction profiles to prevent overheating and thermal degradation. We custom-engineer each screw geometry to match your specific material blends.
Thickness consistency is maintained through a combination of components: a high-precision melt pump that feeds the polymer at a constant pressure, a T-die featuring micro-adjustment bolts, and an automatic thickness gauge system. Closed-loop control systems dynamically adjust the die gap and puller speeds to keep thickness variations within ±1% across the entire width of the sheet.
We offer comprehensive global installation and training services. Our technical team supports customers through remote video diagnostics, detailed CAD manuals, and electrical schematics. We can also dispatch experienced technicians to your factory for machine assembly, commissioning, and operator training to ensure smooth, efficient production from day one.
Yes, our extruders are built to handle up to 100% recycled flakes. To manage variables in PCR feedstock, we equip our extrusion lines with dual-vacuum degassing ports to extract volatile compounds, alongside high-capacity melt filtration systems that filter out contaminants without causing pressure drops.
