Does the extruder require a melt pump?

When discussing whether an extruder requires a melt pump, we need to first understand the basic functions of both and their roles in plastic processing.

The basic function of an extruder: The extruder is mainly used to transform solid plastic raw materials into continuous, plastic melts through heating, plasticization, and extrusion, and extrude them through molds to form the desired shape of the product. Extruder is one of the indispensable equipment in the plastic processing process.

The basic function of a melt pump: a melt pump, also known as a gear pump, is mainly used to pressurize, stabilize, and measure the melt. In the plastic processing process, the melt pump can ensure the stability and continuity of the melt during transportation, and can also accurately measure the flow rate of the melt. This is particularly important for plastic processing processes that require high-precision control of product quality and size.

Now, let's analyze whether the extruder needs a melt pump:

For some simple plastic processing processes, such as the production of low demand extruded products, a melt pump may not be required. The extruder itself is capable of completing basic plasticizing and extrusion functions.

However, in complex plastic processing processes that require high-precision control of product quality and size, as well as ensuring the stability and continuity of melt transportation, the role of melt pumps becomes particularly important. By pressurizing, stabilizing, and metering the melt through a melt pump, the quality and accuracy of the product can be greatly improved.

Therefore, whether an extruder requires a melt pump depends on the specific plastic processing process and requirements. In some machining processes that require high-precision control and stability, the melt pump is an essential equipment. In some simple machining processes, a melt pump may not be required.
