Plastic drawing melt pump application range

Plastic wire drawing melt pumps have a wide range of applications in plastic wire drawing and related industries:

1. Chemical fiber drawing

In polyester, nylon and other chemical fiber drawing production, melt pumps by stabilizing the flow and pressure, significantly improve the fiber strength, gloss and uniformity, and become a key guarantee of high-quality drawing process. Its core functions include:

Stabilizing die head pressure: Reducing the interference of pressure fluctuation on fiber quality and ensuring uniform fiber thickness;

Linear flow rate output: to realize the linear relationship between flow rate and rotational speed, which facilitates the precise control of process parameters; Optimize fiber properties: positively affect the fiber strength, gloss and other physical properties to meet the textile industry's strict requirements for fiber quality.

2. Plastic flat wire production

In the plastic flat wire manufacturing process, the melt pump through precise control of the melt flow and pressure, to ensure the uniformity of flat wire wall thickness and dimensional accuracy. The advantages of this application include:

Improved product consistency: Reduced wall thickness deviations due to fluctuations in flow rate and improved stability of flat wire quality;

Reducing scrap rate: Reducing scrap rate and optimizing production efficiency by stabilizing process parameters;

Diversity of suitable materials: it can handle PE, PP and other common plastic materials to meet the needs of different industries.

3. Polymer material processing

Melt pumps can be adapted to a variety of polymer materials such as fluoropolymers, polyesters, thermoplastic elastomers, etc., and their applications cover:

Film drawing: to ensure the uniformity of film thickness and improve the quality of packaging materials;

Pipe extrusion: to achieve precise control of pipe wall thickness and optimize mechanical properties;

Composite material processing: stabilizing the melt flow of each layer in the multi-layer co-extrusion process to enhance the performance of composite materials.

4. Precision extrusion system

In the production of medical plastic catheters, optical fibers and other precision products, the melt pump meets the demand for high precision through the following characteristics:

Flow rate precision control: accuracy of up to ±0.5% ensures dimensional stability of micro products;

Pressure fluctuation buffer: reduce the impact of upstream equipment pressure fluctuations on the downstream, to ensure process continuity;

Process adaptability: suitable for small diameter catheters, high transparency fibers and other special products extrusion needs.
