Application and Advantages of High-Temperature Melt Delivery Pumps in Extrusion Molding

High-temperature melt delivery pumps play a crucial role in the extrusion molding process of industries such as plastics, resins, rubber, and chemical fiber products. The following is a detailed analysis of their functions:

Precise Delivery

High-temperature melt delivery pumps employ sophisticated control systems and mechanical structures to accurately control and deliver molten materials. This precision ensures the stability of flow and pressure during the extrusion molding process, thereby enhancing product quality and consistency.

Stable Flow

The gear design of the delivery pump is key to achieving stable flow. Through proper gear engagement and sealing structures, the pump effectively isolates the impact of pressure and flow fluctuations in the feed zone on the discharge zone. This design ensures flow stability during the delivery of molten materials, providing reliable assurance for subsequent extrusion molding.

Reduction of Bubbles and Defects

Stable pressure and flow help reduce or eliminate bubbles, voids, or defects in molten materials. These bubbles and defects often affect product quality and performance, and high-temperature melt delivery pumps effectively minimize their occurrence by providing stable delivery conditions.

Temperature Control of Molten Materials

High-temperature melt delivery pumps are typically used in conjunction with heating systems to ensure temperature stability during the delivery of molten materials. Through precise temperature control, the pump maintains molten materials within the optimal process temperature range, ensuring smooth extrusion molding and stable product quality.

High-temperature melt delivery pumps have a wide range of applications and play an important role in the extrusion molding industry. They not only improve product quality and consistency but also reduce production and maintenance costs, providing strong support for the sustainable development of enterprises.
