What is the measurement accuracy of the melt pump?

The metering accuracy of melt pumps is quite high, as detailed below:

I. High-Precision Metering

Melt pumps, especially mechanical melt metering pumps with high-precision gear clearance and volumetric structure design, can achieve high-precision metering. Their metering accuracy typically reaches within ±1%, and some high-precision gear metering pumps can even achieve an accuracy of ±0.5% or 0.3%. This high-precision metering capability is crucial for production processes that require strict control of material delivery volumes.

II. Stable Extrusion Characteristics

Melt pumps not only possess high-precision metering capabilities but also achieve stable extrusion. Since melt pumps can eliminate feeding errors from the feeding system and weaken fluctuations transmitted from upstream processes, they can quickly enter a stable working state. This stability ensures the continuity and consistency of the extrusion volume during the production process, thereby improving product quality and production efficiency.

III. Wide Range of Applications

Melt pumps are suitable for conveying various liquids, including corrosive liquids and melts of different viscosities and temperatures. In industries such as chemical fibers, plastics, resins, and rubber, melt pumps are widely used in extrusion molding processes. Especially in the production of sheets and films, the stable extrusion and precise metering functions of melt pumps are of great significance for improving product quality and production efficiency.

IV. Influencing Factors

Although melt pumps have high metering accuracy, their actual metering accuracy may be affected by various factors. For example, pump design, manufacturing accuracy, material selection, working environment, as well as operation and maintenance methods may all impact metering accuracy. Therefore, when selecting and using melt pumps, it is necessary to comprehensively consider these factors and take corresponding measures to ensure the pump's high-precision metering capability.

In summary, melt gear pumps possess high-precision metering capabilities and can achieve stable extrusion. This high precision and stability make melt pumps play an important role in the extrusion molding process, which is of great significance for improving product quality and production efficiency.
