Wenzhou Yicai Machinery Technology Co., LTD. — Advancing Plastic Thermoforming and Extrusion Capabilities Since 2010
The machinery industry is a highly technology-intensive manufacturing sector requiring deep expertise, structural design, complex metal fabrication, and digital automation. At Wenzhou Yicai Machinery Technology Co., LTD., we are committed to meeting the highest international standards of environmental protection, energy conservation, and system efficiency. Originally founded in 2010 as "Ruian Seven Star Machinery" and officially rebranded in 2022 to leverage global growth, we maintain state-of-the-art research, design, and manufacturing facilities in Wanquan Town, Zhejiang Province—one of China’s premier industrial equipment manufacturing zones.
Our operational philosophy is built on technical precision, high-quality international component sourcing, and comprehensive engineering support. We manufacture thermoforming systems, curved offset printers, co-extrusion sheet equipment, and fully integrated auxiliary machines designed to withstand high-volume production cycles. By integrating servo-driven motion controls and multi-layer structural co-extrusion technology, we empower international manufacturers to optimize materials, reduce scrap rates, and secure operational stability.

A technical guide to polymer behaviors, co-extrusion technology, and machine-molding optimizations
Thermoforming is a physical-mechanical process where thermoplastic sheet material is heated to its specific softening temperature (glass transition and melting zones) and subsequently stretched into or over a mold shape using vacuum pressure, positive air pressure, or mechanical plug assists. The physical properties of the chosen polymer drastically affect machine calibration requirements. Common materials processed by Yicai machines include:
In modern industrial applications, single-layer sheets often fall short of oxygen barrier and mechanical protection requirements. Multi-layer co-extrusion technologies (such as ABA, AB, or ABC structures) allow manufacturers to sandwich barrier layers (e.g., EVOH) or lower-cost recycled regrind material between virgin outer layers. Our Multi-layer Co-extruded Sheet Machine integrates high-torque extruders, precise gear pump melt-metering, and custom T-dies to produce uniform sheets with micro-meter thickness accuracy, lowering overall raw material costs while maintaining food safety standards.
Historically, thermoforming lines relied heavily on hydraulic cylinders to drive plug assists and mold platens. While hydraulics provide high forces, they suffer from heat dissipation issues, oil contamination risks (critical in food packaging), and high energy consumption. Wenzhou Yicai’s Fully Servo Multi-station Tray Thermoforming Machine integrates synchronized AC servo motors. Servo drives offer precise speed control, fast response times, absolute repeatability of platen movements within 0.05mm, and up to 40% reduction in electrical power consumption, translating to lower operational costs and zero risk of oil leaks.
Why sourcing industrial-grade extrusion and thermoforming machinery from Wenzhou, Zhejiang delivers unmatched ROI
Industrial machinery procurement requires evaluating both initial capital expenditure (CAPEX) and ongoing operational reliability. Based in Wenzhou, Zhejiang, Wenzhou Yicai Machinery operates within the heart of one of the world's most concentrated mechanical manufacturing clusters. This unique geographical and industrial placement provides several core benefits for global procurement teams:
Our proximity to localized metal casting, heat treatment, CNC high-speed machining centers, and raw material suppliers allows us to source premium materials with minimum transit time, accelerating production and lowering logistical costs.
Zhejiang’s rich history in packaging and printing technology means our workforce consists of skilled assembly technicians, electrical programmers, and mold designers who understand the micro-tolerances required for high-speed automated forming.
We utilize premium materials like high-grade duralumin and hardened tool steel for our molds, machined on high-precision CNC routers. This guarantees clean cutting edges, minimal web scrap, and mold durability exceeding several million cycles.
Integrated processing lines optimized for food packaging, medical trays, and commercial plastic containers
Our solutions range from raw polymer pellet handling to finished packaged containers. In typical production lines, the Plastic Sheet Extrusion Machine converts polymer resins into roll stock. The roll is then fed directly into the Thermoforming Machine, where custom molds form, punch, and stack the products. For cup production, the inline or offline Curved Offset Plastic Cups Printing Machine prints up to 6 or 8 colors before the Packaging Machine completes row counting and bagging.
Technical guidance and sourcing information for global thermoforming machinery buyers
Multi-layer co-extrusion (e.g., ABA or ABC structures) allows manufacturers to place cheap, recycled plastic regrind or structural fillers inside the core layer (B), while using pristine, virgin, food-grade polymers on the outer layers (A & C). This significantly reduces material costs by up to 30% without compromising physical appearance, printability, or compliance with food contact safety regulations.
We use advanced CNC centers to mill molds from solid duralumin blocks or high-strength tool steel, depending on production requirements. Our engineers carefully compute thermal expansion and shrinkage dynamics for PP, PET, and PLA sheets to design molds with precise water-cooling channels. This ensures uniform temperature distribution, avoiding container warping and reducing cycle times to maximize output.
Servo drives provide absolute position repeatability (within 0.05 mm), faster mechanical cycles, and consume energy only during motion (unlike hydraulic pumps that run continuously). Additionally, servo systems eliminate hydraulic fluid, preventing oil leaks and cleanroom contamination risks, making them perfect for pharmaceutical and food-grade packaging.
For standard setups, manufacturing ranges between 45 to 60 days. Fully customized lines (including complex multi-cavity thermoforming molds and inline curved offset printing configurations) may require 75 to 90 days. Testing with your specific materials is performed at our Wenzhou factory before shipping.
We provide digital operational documentation, step-by-step installation videos, and electrical schematics. For plant commissioning, we can dispatch field engineers to set up equipment and train local operators. Remote diagnosis is supported on our PLC models, allowing our engineering team to troubleshoot code and settings online.
