## Saying Goodbye to Generic Solutions: **Proprietary PLC System** Reshapes the Industry's Technological Landscape

For a long time, the domestic air-cooled pelletizing machine market has relied heavily on manual operation, completely dependent on workers' experience. This has led to significant shortcomings in the specificity of the pelletizing process, response speed, and fault identification accuracy: either it fails to accurately match the pelletizing parameters of different materials, or it requires manual identification of fault locations, which is time-consuming and becomes a key bottleneck restricting enterprise production efficiency.

 

To address this industry pain point, Luntech assembled a 12-person dedicated R&D team, spending 5 years deeply integrating pelletizing process and intelligent control technology.  They successfully developed a **dedicated PLC intelligent control system for pelletizing machines**—the first customized control system in China completely developed based on the entire air-cooled pelletizing process. It holds 2 utility model patents and 1 software copyright. From the underlying algorithms to the functional modules, everything is exclusively designed by Luntech, completely eliminating reliance on manual labor and achieving deep adaptation of "process and control."

 

## Three Core Proprietary Advantages Define a New Standard for Efficient Production

### 1. One-Click Start/Stop + Customized Programs, Doubling Operational Efficiency

Unlike the complex parameter settings of general-purpose PLCs, Luntech's proprietary PLC system has **100+ built-in parameter templates for common materials** (covering mainstream polymer materials such as PP, PE, and PVC). Operators do not need to manually adjust parameters; after selecting the corresponding material type, pressing the "Start" button triggers the fully automatic production process. When stopping, the system automatically completes material clearing, equipment cooling, and other finishing actions. The entire process takes only 30 seconds, improving operational efficiency by 3 times compared to traditional equipment. New employees can operate independently after only 1 hour of training.

 

Even more noteworthy is that the system supports enterprise-defined parameter storage—for special materials or personalized pelletizing needs, technicians can save exclusive parameter schemes, which can be recalled with just one click, completely solving the problem of frequent adjustments during multi-variety production. ### 2. Millisecond-Level Fault Identification, **Proprietary Diagnostic Model for Granulation Scenarios** for Precise Localization

Based on a deep understanding of the granulation process, Lunt has embedded a **proprietary fault diagnostic model** in its PLC system: unlike general systems that only monitor basic data such as current and temperature, this model can collect 15 granulation-specific data points in real time, including "material melt degree, die head pressure, and cutter speed matching." Through independently developed algorithms, it can issue warnings 0.5 seconds before a fault occurs, with a fault identification accuracy of 99.2%.

 

For example, when the die head is blocked due to excessive material humidity, the system will not only immediately stop and alarm, but also display the "blockage location (die head outlet hole #3) + solution (increase drying temperature to 85℃ and clean the outlet hole)" on the touchscreen.  Technical personnel do not need to disassemble the equipment for troubleshooting, reducing the average fault handling time to 5 minutes, an 80% reduction compared to the industry average, minimizing production losses.

 

### 3. Intelligent Linkage + Energy Saving Optimization, Balancing Efficiency and Cost

The Lunt PLC system is not an isolated control unit, but rather achieves **deep intelligent linkage** with the equipment's mechanical structure and cooling system: when the system detects fluctuations in material melt degree, it automatically adjusts the heating power and screw speed to ensure uniform granule formation; the cooling process adjusts the air cooling volume in real time according to the cutter speed and granule size, avoiding energy waste. Third-party testing shows that air-cooled granulators equipped with this system achieve a 22% increase in energy efficiency compared to similar equipment using general-purpose PLCs, and the granule pass rate remains stable at over 99.5%.

 

At the same time, the system has a **data traceability function**—it automatically records the parameters, output, and fault information of each production batch, generating visual reports to facilitate production management and quality traceability, helping to create an "intelligent and transparent" production workshop.

 

## Field Verification: A Reliable Choice from the Laboratory to the Production Line

Since the new generation of air-cooled granulators entered the testing phase, it has been field-tested in several plastic processing companies. A representative from a large automotive interior parts manufacturer stated: "Previously, we used a general-purpose PLC system, which required repeated parameter adjustments during material changes and frequently caused production delays due to inaccurate fault diagnosis.  After switching to Lunter's equipment, the dedicated PLC system is incredibly easy to use.  We can start production with a single click after selecting the materials.  Last time, the die head was about to clog, but the system provided an early warning, preventing any disruption to production.  Our production capacity has increased by 35% in the past six months, and we've also saved a significant amount on electricity costs."
