Explore our primary industrial production systems. We specialize in high-efficiency, multi-station plastic and paper thermoforming machines designed for massive throughput and clean structural operations.
The global demand for high-quality disposable containers has prompted a significant paradigm shift in the machinery manufacturing sector. Industrial processors require equipment that delivers not only sheer speed but extreme material adaptability, mechanical reliability, and structural efficiency. Formerly known as Ruian Seven Star Machinery (established in 2010), Wenzhou Yicai Machinery Technology Co., LTD. rebranded in 2022 to spearhead a new era of high-tech production. Today, we stand as a premier research-oriented Chinese factory specializing in advanced thermoforming machinery and complete inline downstream solutions.
Modern plastic machinery engineering is characterized by its high concentration of advanced disciplines—from computer-aided design (CAD) to automated PLC motion control networks. Our production systems integrate complex metallurgical casting, precision CNC machining, gas-assisted high-pressure forming, and synchronized robotic stacking. In an era where ecological considerations and global export standards are tightly regulated, we offer comprehensive machinery optimized for high energy savings, compatibility with biodegradable materials like PLA and starch-based resins, and raw-material scrap reduction.
Integrating multiple mechanical stages into a seamless, high-speed automated cycle is crucial for processing margins. The blueprint below illustrates the critical functional systems of our production setups.
Utilizing combined pneumatic pressure (up to 0.6-0.8 MPa) and high vacuum forces, our multi-station thermoformers achieve unmatched wall-thickness uniformity. The positive pressure shapes complex structures and deep-draw ratios (up to 150mm) while ensuring ultra-crisp embossing, crucial for branded hot-beverage containers.
Raw plastic polymers must undergo precise melting, compounding, and sheet calibration. Our extrusion lines construct structures (like PP, PS, PET, EVOH barrier films, and PLA) with multi-layer configurations. This structure prevents odor permeation and preserves freshness, matching target density specs.
High-fidelity labeling is achieved post-thermoforming via multi-color offset printing units (up to 8 colors). These printers work continuously at linear speeds exceeding 300 cups per minute, deploying UV curing arrays to seal food-safe inks permanently onto the curved surface of the plastic cups.

We provide continuous business support for enterprise procurement departments worldwide, balancing capital investments with high operational yields.
We tailor programs according to customer specifications, including custom forming molds, custom colors, electrical component specs (Siemens/Omron), and downstream output configurations.
Transitioning from manual workflows to semi-automatic, and finally to fully automated PLC systems. We adapt technologies to optimize material usage and reduce energy consumption.
Manufactured using strict quality management systems. Our components undergo structural load tests and continuous run-in periods before leaving the assembly line.
Our sales engineers provide layout diagrams, cycle-time calculations, material compatibility audits, and comprehensive utilities guides (electricity, water, air pressure).
Our machinery has been successfully exported to diverse markets, including Southeast Asia, the Middle East, South America, Eastern Europe, and North America.
Composed of senior mechanical designers, software engineers, and experienced assembly technicians who maintain quality standards across every build phase.
We source critical electronic and mechanical parts from reputable brands like Schneider, Omron, SMC, Yaskawa, and Delta to ensure long-term stability.
We provide virtual diagnostic support, operational tutorials, spare parts lists, and send engineers for on-site commissioning and training.
China's manufacturing prowess is no longer based solely on cost. In the packaging machinery sector, the industrial clusters of Zhejiang Province—specifically the Wenzhou-Ruian machinery hub—provide distinct manufacturing benefits:
In response to tightening single-use plastics legislation, global manufacturing is shifting toward a circular model. The machinery must be versatile enough to process standard polymers and emerging bio-plastics:
For large-scale food packaging operations, standalone machines can lead to production bottlenecks. Wenzhou Yicai Machinery supplies integrated inline production pathways designed to eliminate storage buffers and minimize manual handling:
Raw plastic granules are extruded directly into calibrated sheet rolls, eliminating cooling and reheating phases for optimal energy conservation.
The sheet passes through multi-zone infrared preheaters directly into mold stations for forming, cutting, and stacking, reducing cycle times.
Excess plastic skeleton trim is immediately guided to a grinder and recycled back into the co-extruder, achieving near-zero waste production.
Take a virtual look inside our ISO-compliant manufacturing center, located in Zhejiang Province. Our facility is equipped with automated assembly blocks, precision milling machinery, and strict testing zones.
Our facility incorporates 13 specialized manufacturing bays, allowing our engineering team to simultaneously construct multiple custom orders. With dedicated assembly sectors for heavy-duty metal casting, mechanical alignment, and electronics testing, Wenzhou Yicai ensures that each unit is built to withstand high production loads.
