Common problems in the extrusion process of plastic extruders include raw material problems, equipment problems, operation problems and post-processing problems. This article will introduce the common problems and solutions of the extrusion process of plastic extruders in detail from these four aspects.

1. Raw material problems

1. Too many impurities or too much water in the plastic raw materials will lead to poor extrusion molding or substandard product quality. Solution: It is necessary to screen or dry the raw materials before production, and strengthen the control and inspection of raw material quality.

2. Problems with the proportion of plastic raw materials, such as improper matching, too much or too little additives, will lead to poor extrusion molding or substandard product quality. Solution: It is necessary to reasonably control the proportion of raw materials according to factors such as the process requirements of the product.

2. Equipment problems

1. Modulation problems of the extruder, such as improper temperature setting, blockage or poor wear at the extrusion head, will lead to poor extrusion molding effect or substandard product quality. Solution: It is necessary to adjust the parameters such as the temperature of the extruder, the pressure and speed of the extrusion head to ensure that the equipment is in good condition.

2. Improper cleaning and maintenance of the equipment will also affect the extrusion effect. Solution: Clean, maintain and inspect the equipment regularly to detect and deal with equipment failures and damage in a timely manner.

3. Operational problems

1. The operator's lack of understanding of the equipment and process requirements leads to poor extrusion molding effect or substandard product quality. Solution: Operators need to be trained to improve their understanding and mastery of equipment and processes.

2. Poor operating environment, such as temperature, humidity and other factors will affect the extrusion molding effect. Solution: It is necessary to create a good production environment to ensure that factors such as temperature and humidity are within an appropriate range.

4. Post-processing problems

1. Unskilled or improper operation of post-processing techniques such as wire drawing and cutting will affect product quality. Solution: Post-processing operators need to be trained and guided to ensure proficiency in post-processing techniques and correct operation.

2. Damage to post-processing equipment or improper maintenance will also affect product quality. Solution: Regularly inspect, maintain and maintain post-processing equipment to promptly detect and handle equipment damage and failures.

In short, the common problems of plastic extruder extrusion process are multifaceted, and it is necessary to comprehensively consider factors such as raw materials, equipment, operation and post-processing, and select appropriate solutions according to specific circumstances to ensure product quality and production efficiency.
