▏Product Introduction
25 Co-extruder is an extrusion equipment specially designed to adapt to the small co-extruder flow and can be interfacing with different forms of the main machine. The following is a detailed introduction to the 25 co-extruder:
| 1 | Basic concepts |
| Name: 25 co-extruder, sometimes referred to as 25/25 color line extruder or 25 model co-extruder single screw extruder. Usage: Mainly used for plastic pipe (such as PE, PPR pipe) co-extrusion production, also suitable for laboratory and other occasions |
| 2 | The main characteristics |
| 2.1. Compact structure: small footprint, easy to arrange and operate in a limited space. 2.2. Easy operation: equipped with a small control system, making the operation more simple and fast. 2.3. Strong versatility: easy runner interface design, so that it can be used with other types of extruders, the production of multi-layer structure of products. 2.4. Easy disassembly and maintenance: The mobile rack design is convenient for disassembly and maintenance when needed. |
| 3 | Technical parameters (Taking a certain model as an example) |
|
Screw diameter: Φ25mm Screw length to diameter ratio: Generally 25:1 (specific ratio may vary by model) Drive motor power: Depending on the model and configuration, the drive motor power varies, such as a model may be 0.75KW or higher. Production capacity: Depending on the raw material and process, production capacity will vary, but generally can meet the needs of laboratory or small-scale production. |
| 4 | The working principle |
|
25 Co-extruder adopts melt co-extrusion technology to mix and homogenize different plastic materials through the same extruder, and then extrude them through the co-extruder die head. In the die head, different plastic materials pass in turn according to the multi-layer structure required by the product, and finally form a product with a multi-layer structure. |
| 5 | Application fields |
|
Plastic pipe production: mainly used for the co-extrusion production of PE, PPR and other plastic pipes, which can produce multi-layer composite materials with a variety of functions and characteristics. Laboratory research: It is also suitable for laboratory and other occasions to carry out co-extrusion experimental research of plastic materials. |
| 6 | Precautions |
|
When using 25 co-extruder, the operation procedures should be strictly followed to avoid safety accidents. Check and maintain the equipment regularly to ensure the normal operation and service life of the equipment. Select the right model and configuration according to the production needs to achieve the best production results and economic benefits. |
