Process Flow and Quality Control of Thermosetting Plastics Extruder

Release time:

2024-06-20

The process of thermosetting plastic extruder is a complex and delicate process, which is mainly used to produce thermosetting plastic products with specific shapes and properties.

First of all, raw material preparation is a key step. The pretreated thermoset plastic pellets are fed into the feed throat of the extruder. These particles need to meet certain quality requirements to ensure that the subsequent processing process is carried out smoothly.

Next, the plastic pellets begin to melt gradually inside the extruder by the rotation of the screw and the heating at a high temperature. In this process, it is necessary to strictly control the heating temperature, screw speed and other parameters to ensure that the plastic can be uniformly melted to form a flowing state.

When the plastic is melted, the molten plastic is shaped by the die of the extruder head by the pushing action of the screw. The shape and size of the mold determine the shape and size of the product. During the extrusion process, a certain amount of extrusion strength needs to be maintained to ensure that the plastic can pass through the mold smoothly and form the desired shape.

In addition, upon cooling and curing, a thermoset plastic article is formed. These products have excellent heat resistance, corrosion resistance and mechanical properties, and are widely used in electronics, aviation, automobiles and other fields.

In general, the process of the thermosetting plastic extruder needs to strictly control the parameters and conditions of each link to ensure the production of high-quality thermosetting plastic products.
