A leading machinery enterprise formerly known as "Ruian Seven Star Machinery", evolving into an elite ODM technology innovator.
The machinery manufacturing industry is a cornerstone of modern industrial scaling, demanding rigorous design capabilities, high-precision engineering, and reliable automation. Wenzhou Yicai Machinery Technology Co., LTD., established in 2010 and restructured in 2022, operates as a high-technology industrial pioneer in East China's coastal Zhejiang Province. We bridge the gap between design processes, advanced sheet metal welding, complex multi-station assembly, and intelligent automation control systems.
Our company focuses primarily on producing state-of-the-art thermoforming machines, curved offset presses, plastic sheet extrusion machines, and related auxiliary packaging equipment. Our industrial strategy is designed around green energy profiles, reduced material waste ratios, and high durability parameters, allowing global procurement managers to establish reliable manufacturing units in food services, consumer products, and packaging.
In the modern era of packaging, global supply chains demand a delicate balance between material optimization, manufacturing velocity, and strict compliance with ecological guidelines. This white paper analyzes the engineering innovations driving modern plastic thermoforming, sheet extrusion, and curved offset printing systems, highlighting the technical workflows implemented by Wenzhou Yicai Machinery Technology Co., LTD.
Historically, global buyers treated thermoforming and printing equipment as localized commodities. Today, high-capacity food service manufacturers, consumer packaging firms, and industrial molding operations require optimized, single-supplier solutions that handle everything from raw granule extrusion to final high-speed nesting and packaging. Our original ODM designs address this requirement through fully automated thermoforming production cells that link extrusion, shaping, hole punching, and trimming into one synchronous line.
"True ODM excellence is determined by how closely the mechanical kinematics align with polymer dynamics. From structural CAD models to high-cycle thermoforming molds, thermal dissipation paths dictate output success."
The transition from traditional hydraulic actuators to closed-loop electric servo motors represents a massive step forward in mechanical precision. By using multi-axis servo controllers on our sheet-feed, mold-clamping, and plug-assist drives, we achieve repeatable molding tolerances within ±0.1mm.
This precision is critical for manufacturing tight-fitting lids, complex multi-compartment containers, and deep-drawn cups. Multi-station systems combine forming, cutting, and stacking into a single workspace, minimizing material shrinkage, thermal warping, and manual contamination risks.
| System Type | Traditional Hydraulic forming | Advanced Servo Multi-Station |
|---|---|---|
| Kinematic Accuracy | ±0.5 mm to ±0.8 mm | ±0.1 mm |
| Cycle Velocity | 20 - 25 Cycles/min | Up to 45 Cycles/min |
| Energy Consumption | Baseline (100%) | 35% - 40% Reduction |
| Scrap Ratio Control | 3% - 5% Average | < 0.8% with Online Crusher |
A high-quality container begins with a high-quality sheet. Modern packaging demands high-barrier layers to extend shelf life for organic food, dairy, and pharmaceutical products. The plastic sheet extrusion machines developed at Wenzhou Yicai Machinery process PP, PS, PET, and PLA polymers through multi-layer co-extrusion technology.
By controlling the polymer melt viscosity and shear stress with advanced screw geometries (featuring an L/D ratio of 30:1 or higher), we guarantee thickness uniformity across the sheet width. This consistency eliminates thin-wall defects during deep-draw thermoforming processes.
In the retail beverage and consumer sector, container aesthetics directly impact brand value. Printing on curved surfaces, such as plastic cups and round buckets, presents significant mechanical challenges. Wenzhou Yicai Machinery specializes in high-velocity multi-color curved offset press printers that run up to 6 colors simultaneously.
Using precision rotary mandrels, flame pre-treatments, and integrated UV curing systems, our machines guarantee sharp ink adhesion, high registration accuracy (±0.15mm), and print rates exceeding 300 cups per minute.
Sustainability is no longer optional. During thermoforming processes, edge trim scrap can account for up to 30% of the total sheet area. To solve this, Yicai Machinery integrates sheet machine edge material online crushers.
These crushers immediately reduce edge trim to high-purity regrind, which is pneumatically fed back into the co-extruder hopper. This closed-loop system reduces raw material costs and eliminates storage, shipping, and contamination risks associated with off-line recycling.
Looking forward, our technology roadmap focuses on two main pillars: smart IoT factory integration and processing complex biopolymers.

Technical guidance and answers for procurement managers and machinery engineers.
Standard thermoforming molds (such as plastic cup or lid molds) require 30 to 45 days for CAD design, CNC steel machining, and validation testing. Large-scale multi-station thermoforming lines or co-extrusion systems require 60 to 90 days, depending on voltage customization and configuration options.
To simplify regional maintenance for our global customers, we use standard, internationally recognized components. Our electronic control systems and servo drives integrate components from Yaskawa, Omron, Siemens, and Schneider. Pneumatic systems utilize SMC or Airtac components.
The online crusher processes the skeletal scrap sheet left behind during the thermoforming process. It automatically grinds and cycles the clean material back into the extruder feed throat. This setup maintains consistent sheet properties and reduces raw material waste to less than 1% of total input.
Our systems process multiple polymer types, including Polypropylene (PP), Polystyrene (PS), Polyethylene Terephthalate (PET), and Polylactic Acid (PLA). PLA and other biopolymers require custom heating curves and air knife designs, which we configure during the initial assembly phase.
