Extrusion molding is a very important manufacturing process that is widely used in various fields. It can achieve high efficiency, precision, and cost control of products, bringing huge benefits to industrial production. With the continuous development of technology, extrusion molding technology is also constantly innovating and improving, which will provide more possibilities for the future development of the manufacturing industry.

With the development of technology and the improvement of processes, extrusion molding technology is also constantly advancing. For example, new technologies such as twin-screw extruders and vacuum extruders have been introduced to improve product quality and production efficiency; Meanwhile, extrusion molding is also widely used in the development and production of new materials, such as biodegradable plastics, composite materials, etc.

How to maintain molding accuracy during the extrusion molding process in Dalian?

Choosing the appropriate extruder and mold: Extruders and molds are key equipment for extrusion molding, and selecting the appropriate extruder and mold is crucial for maintaining molding accuracy. Firstly, it is necessary to select the model and specifications of the extruder according to the products that need to be produced, to ensure that it can meet the requirements of the product. At the same time, it is necessary to choose high-quality molds to ensure that the molds can stably manufacture the shape and size of the product.

Control extrusion process parameters: During the extrusion molding process, by controlling the temperature, pressure, speed, and other process parameters of the extruder, the flowability and molding time of the material can be adjusted, thereby affecting the molding accuracy. It is necessary to set the extrusion process parameters reasonably according to the characteristics of the material and the requirements of the product, in order to maintain the forming accuracy.

Regular inspection and maintenance of equipment: Extruders and molds are the core equipment for extrusion molding, and regular inspection and maintenance are crucial for maintaining molding accuracy. Regularly inspect the components of the equipment for wear or damage, replace aging parts in a timely manner, and ensure the normal operation of the equipment. At the same time, it is necessary to maintain the cleanliness and lubrication of the equipment to improve its service life and stability.

Using high-quality raw materials: Choosing high-quality plastic materials is also crucial for maintaining molding accuracy. High quality raw materials have uniform particle size and good flowability, which can ensure the uniformity and stability of the material during extrusion molding, thereby improving molding accuracy.

The process flow of extrusion molding usually includes the following steps: raw material preparation, heating, extrusion, cooling, and cutting. Mix or pretreat the raw materials that need to be processed in a certain proportion to ensure their uniformity and quality. Then, put the raw materials into the extruder for heating, making them viscous and easy to squeeze. Next, the raw material is extruded into a mold with a matching shape through the screw of the extruder, and cooled and solidified while maintaining the same shape. Cut or process the cooled product to achieve the final molded product.

Extrusion molding is widely used in various fields due to its characteristics of gradual production, high continuity, high efficiency, and simple operation. For example, in the construction industry, extrusion molding can be used to produce building materials such as PVC pipes and window frames; In the packaging industry, extrusion molding can be used to produce various plastic packaging films, pipes, and other products; In the automotive industry, extrusion molding can be used to produce components such as sealing strips and decorative strips for automobiles.
