Explore our high-performance sheet extrusion lines and auxiliary industrial packaging systems engineered for global factories.
Insight analysis from engineering standards, energy optimization, and circular economy requirements.
Modern sheet production centers heavily on multi-layer co-extrusion (such as ABA, ABCBA configuration) to reduce raw material costs. Manufacturers utilize recycled post-consumer waste (PCR) or industrial regrind in the core layer while wrapping it with virgin polymer resins (such as PP, PET, PS, or PLA) on outer surfaces to preserve barrier properties and visual appeal.
With global plastic restriction mandates, sheet extruders must operate dynamically with biodegradable materials like PLA (Polylactic Acid) and starch-based resins. Processing PLA requires exact crystallizing drying systems and precise screw geometry to limit molecular weight degradation caused by moisture exposure and shear-induced overheating.
Industrial IoT integrations, gravimetric dosing feedback loops, and closed-loop automatic T-die thickness controllers are now standard components. These systems ensure sheet thickness variances are maintained within ±1% limits, resulting in minimal material waste during high-speed thermoforming steps downstream.
Founded originally in 2010 under the corporate name "Ruian Seven Star Machinery" and restructured as "Wenzhou Yicai Machinery Technology Co., LTD." in 2022, we are located in East China's Zhejiang coastal industrial zone. Supported by an experienced research and development engineering staff and high-precision manufacturing equipment, we manufacture and distribute complete thermoforming plants, offset printing equipment, and custom plastic sheet extruder lines.
The machinery manufacturing industry is a complex, technology-intensive field requiring strong engineering architecture, automated system design, metallurgy, and precise assembly protocols. At Wenzhou Yicai, we focus closely on environmental protection, energy conservation, and robust machinery lifespans, enabling our international client base to operate efficiently in competitive environments.

With production systems deployed worldwide, our logistics, compliance, and field service structures are built to address complex international shipping and commissioning requirements.
We source key mechanical and electrical components from leading international brands (Siemens, Schneider, Omron, ABB), minimizing the risk of unscheduled downtime.
Our multi-disciplinary team brings together machine designers, control programmers, polymer process technicians, and quality inspectors to oversee every step of production.
We provide long-term technical assistance, spare parts support, and remote troubleshooting to keep production lines operating smoothly.
A clean, organized production floor focused on precision assembly, testing, and systematic quality verification.
A detailed breakdown of critical sub-systems configured for maximum stability and material control.
The core extrusion system utilizes an optimized L/D ratio (typically 30:1 or 33:1) for proper polymer mixing. Screws are treated with bimetallic coatings and nitride processing to resist wear from recycled resins and fillers like calcium carbonate (CaCO3). Dynamic mixing elements ensure melt uniformity without creating excessive shear stress.
Our T-dies feature a coat-hanger internal design to maintain uniform melt pressure across the full width of the die. Micro-adjustable push-pull bolts allow technicians to manually adjust sheet profiles, while automatic thermal bolt systems can link with online thickness scanners for closed-loop corrections.
The cooling phase uses a three-roll calendering unit, configured vertically or diagonally. Each roll is mirror-finished, internally ground, and features an independent water heating and tempering control loop. The design ensures precise sheet cooling rates to minimize internal stress and maintain optical clarity.

Global shipping requires compliance with local standards. All electrical systems from our factories are engineered to comply with EU CE certifications, UL/CSA standards for North American networks, or local regulatory inspections. Multi-language HMI interfaces are pre-installed for easy local operator training.
Our logistics team manages the transport of oversized machinery frames, T-dies, and heavy rolls. Field services include on-site mechanical alignment, electrical routing calibration, and trial runs using local resins to verify target output metrics before production begins.
Evaluating procurement involves reviewing more than just the initial equipment investment. We address TCO by utilizing premium energy-efficient heating systems, long-lasting bimetallic wear parts, and interchangeable modular components that lower maintenance overhead over years of service.
