Customer's factory: GS-mach 75/180 Two stage extruder with Automatic weighing dosage feeding system

"75/180 two-stage extruder with automatic weighing dosage feeding system" refers to a specific type of plastic extrusion system used in the production of polymer compounds or masterbatches. Let's break down the key components and processes involved:
1. Extruder Configuration:
- The "75/180" denotes the configuration of the extruder. It typically means that the system consists of two extruders, one with a screw diameter of 75mm and another with a screw diameter of 180mm. The combination of two extruders in series is known as a two-stage extruder system.
2. Two-Stage Extrusion:
- In a two-stage extrusion process, the smaller extruder (75mm) is often used for the initial melting and compounding of raw materials, while the larger extruder (180mm) performs further melting, mixing, and homogenization of the compound. This allows for more precise control over the processing parameters and ensures a uniform product.
3. Automatic Weighing Dosage Feeding System:
- The extrusion system is equipped with an automatic weighing dosage feeding system. This system is responsible for accurately measuring and introducing various raw materials into the extruders. It helps in maintaining the desired formulation and composition of the polymer compound.
4. Material Handling and Feeding:
- Raw materials, such as polymer resins, additives, colorants, and fillers, are stored in separate bins or containers. The automatic weighing dosage feeding system precisely measures the required quantities of each material and feeds them into the extruders in a controlled manner.
5. Control System:
- The entire extrusion system is likely to be controlled by a sophisticated control system. This system monitors and adjusts key parameters such as temperature, screw speed, and feed rates to ensure optimal processing conditions.
6. Product Quality Control:
- Quality control measures are implemented throughout the process to ensure that the final polymer compound meets the specified criteria. This may involve real-time monitoring of material composition, extrusion parameters, and product characteristics.
7. Applications:
- Extruders with automatic weighing dosage feeding systems are commonly used in the production of polymer compounds, masterbatches, and blends used in various industries, including plastics manufacturing, packaging, and automotive.
8. Efficiency and Consistency:
- The automation provided by the weighing dosage feeding system enhances production efficiency and ensures batch-to-batch consistency in the composition of the extruded polymer compound.
This type of extrusion system is suitable for high-throughput production environments where precision in material composition and consistent product quality are critical requirements. It is often employed in industries that demand customized polymer formulations with specific performance characteristics.
