Introduction to Extrusion Principle and Equipment Composition of Extruder Forming Equipment

Add powder or granular materials, butyl ester, old materials, and calcium powder to the extruder hopper, and continuously stir evenly with a high-speed mixing bucket. Evenly stir the plastic raw materials and extrude them from the porous machine head or metal mesh using an extruder with high extrusion pressure.

Usually, after putting the material into the hopper, the material is extruded using a screw. After using frequency converter speed regulation technology, pressure can be controlled to select an appropriate linear speed.

Extrusion molding is the process of continuously forming a polymer melt through a certain shaped die under the extrusion action of the extruder screw, resulting in a continuous profile with a constant cross-sectional shape.

There are two types of extrusion molding equipment: screw extruders and plunger extruders. The former is continuous extrusion, while the latter is intermittent extrusion. Screw extruders can be divided into single screw extruders, double screw extruders, exhaust extruders, and multi screw extruders, among which single screw extruders are currently the most commonly used and basic extruders in production. Twin screw extruders have developed rapidly in recent years and their applications have gradually become widespread.

After determining the suitable extrusion equipment for oneself, investigate the corresponding extruder manufacturers and prices. The main focus is to examine the scale of the manufacturer, production strength, and the reputation of the customers who use the equipment. Don't be afraid of a long journey. The key to buying equipment is to buy the right equipment with good cost-effectiveness, strong technology and after-sales service, so that you have no worries. If you only buy cheap or nearby equipment, the performance and product quality of the equipment are unstable, and the time, manpower, and money consumed far exceed the initial equipment investment.
