Founded in 2010 as Ruian Seven Star Machinery and dynamically restructured in 2022 as Wenzhou Yicai Machinery Technology Co., LTD., our enterprise operates at the convergence of high-capacity packaging and precision plastic process engineering. Located in Zhejiang Province, East China’s vital manufacturing cluster, we design, engineer, and deploy fully automated production lines that redefine modern industrial efficiency. The machinery industry is characteristically technology-intensive, demanding complex metallurgical integration, precision welding, robust assembly structures, and intelligent automation control systems.
Our operational roadmap addresses critical structural challenges: optimizing thermal performance, reducing energy overheads, maintaining print registry alignment under high speeds, and guaranteeing structural integrity during heavy-duty clamping cycles. By integrating robust machinery design with environmental safeguards, Wenzhou Yicai Machinery supports global enterprises in establishing high-output, energy-efficient plastic and paper container manufacturing plants.
Modern industrial production relies heavily on the integration of thermoforming machinery, multi-layer co-extrusion systems, and inline printing operations. Historically, manufacturers struggled with fragmented setups that increased scrap rates, labor costs, and downtime. Today, Wenzhou Yicai Machinery delivers unified production lines where materials move seamlessly from raw polymer pellets to stacked, counted, and boxed containers.
Our technology is engineered around three core principles: thermal efficiency, mechanical speed, and closed-loop material recycling. By integrating online edge material crushers, our plastic extrusion lines recover up to 100% of thermoforming skeletal waste directly back into the feed throat of the extruder. This process eliminates external waste handling, prevents polymer degradation from multiple heat cycles, and maintains structural properties across multilayer co-extruded sheets.
We tailor solutions according to specific structural designs, mechanical layouts, parts configuration, custom brand decals, and system throughput requirements.
Multi-layer polymer co-extrusion technology enables the production of custom PP, PS, PE, and PET sheets with high barrier performance for food safety.
Our thermoforming and offset printing systems utilize multi-axis closed-loop servo motors to achieve precise positioning, reducing scrap rates.
International commercial production requires machinery that complies with global standards. Over twelve years, Wenzhou Yicai Machinery has developed an international supply chain and client network. The international market demands high equipment reliability, clean power distribution, and readily available component parts.
To address global maintenance challenges, Wenzhou Yicai partners with top-tier international component manufacturers. By sourcing electrical switches, PLC blocks, pneumatic valves, and servo drives from global brands (such as Schneider, Siemens, and Omron), we ensure that replacement parts are accessible locally, minimizing downtime for our global clients.
Our global operations support export compliance, logistics management, and remote diagnostic connectivity for overseas production lines.
We build production machinery tailored to client specifications, supporting standard mold changes, custom profiles, and various raw polymer materials.
Our quality control covers raw material sourcing, structural welding, precision machining, paint finishes, and final system integration testing.
Our machinery is engineered to process a wide range of thermoplastic resins (PP, PS, PET, PVC, PLA, and PE) into diverse food-grade and commercial packaging formats. Different regional markets face varying regulatory landscapes regarding environmental impact, heat-tolerance, and mechanical rigidity. Wenzhou Yicai Machinery supplies processing solutions designed to meet these distinct regional demands.

Wenzhou Yicai Machinery operates internal testing protocols where every machine is subjected to load testing and continuous cycle simulation prior to packaging and shipment.
Our research and development program focuses on advancing mechanical performance in three primary categories: increasing multi-station cycle speeds, expanding automated packaging configurations, and reducing electrical energy consumption per unit produced. Below is Wenzhou Yicai Machinery's roadmap for integrating new automated packaging architectures.
| Equipment Category | Core Innovation Focus | Energy Savings | Automation Interface |
|---|---|---|---|
| Thermoforming Systems | Closed-loop multi-station servo drive configuration. | Approx. 20% compared to pneumatic systems. | Multi-axis PLC control with touchscreen interface. |
| Plastic Sheet Extrusion | Multilayer co-extrusion technology with online edge recovery. | Approx. 15% reduction in heating loads. | Closed-loop temperature controls with automatic feedback. |
| Curved Offset Printing | Direct UV curing systems with high-speed indexing. | Approx. 30% saving on lamp consumption. | Real-time print register control. |
| Automatic Packaging | Flexible multiline counting and inline film wrapping. | Eliminates secondary heating tunnels. | Unified coordination with thermoformer discharge system. |
To assist procurement managers, process engineers, and plant operators in selecting packaging machinery, Wenzhou Yicai's technical department has compiled answers to frequently encountered mechanical questions.
The online edge crusher is designed to process skeletal waste directly from the thermoformer's trim station and return it to the extruder feed throat. This process eliminates manual recycling steps, prevents contamination, and utilizes residual heat from the waste strip to reduce the extrusion system's total heating load.
Servo-driven thermoforming provides precise, repeatable tool travel and control over speed profiles during forming. This control is critical for maintaining uniform wall thickness in deep-draw containers. Additionally, servo drives consume energy only during active movement phases, which reduces total electrical overhead compared to pneumatic cylinders.
Our 6-color and 8-color curved offset presses feature high-speed indexing hubs and precision cylinder gears to minimize backlash. Built-in UV curing systems rapidly cure inks on the tapered surface of plastic cups, preventing smearing and ensuring sharp color registration at production speeds.
Yes, our thermoforming machines are compatible with PLA and starch-based biodegradable polymers. These materials have narrow thermal processing windows, which we manage by dividing our heating ovens into independently controlled heating zones managed by solid-state relays.
The typical production timeline ranges from 45 to 75 days, depending on mechanical complexity and custom mold designs. The customization process begins with structural CAD approval, followed by components selection, tooling manufacture, machine assembly, and final trial runs witnessed by the client via remote video or in-person visitation.
