Extrusion Blow Molding Machine Is An Important Equipment Widely Used in The Field of Plastic Processing.

Publish Time: 2024-09-12     Origin: Site

I. Working Principle


The extrusion blow molding machine heats and melts plastic particles and then extrudes them through an extrusion device to form a tubular parison. Then, the mold closes and sandwiches the parison. Air is blown into the parison through a blowing device to make the parison cling to the inner wall of the mold, thereby forming a plastic product of the required shape. The entire process involves precise temperature control, extrusion speed adjustment, and blowing pressure control to ensure the production of high-quality plastic products.


II. Main Features


  1. High-efficiency production: It can quickly and continuously produce plastic products of various shapes and sizes, greatly improving production efficiency.

  2. Versatility: It can process many different types of plastic raw materials to meet different product needs.

  3. High-precision molding: Through advanced mold design and control technology, high-precision plastic product molding can be achieved to ensure the dimensional accuracy and appearance quality of products.

  4. High degree of automation: Equipped with an advanced control system, it can realize automated production, reduce manual operations, and improve the stability and reliability of production.

III. Application Fields


  1. Packaging industry: Widely used in the production of various packaging containers such as plastic bottles, barrels, and cans, such as beverage bottles, laundry detergent buckets, and chemical raw material buckets.

  2. Automotive industry: Can manufacture plastic parts for automobiles such as interior trim, bumpers, and fuel tanks.

  3. Daily necessities industry: Produce various daily necessities such as plastic basins, buckets, and toys.

  4. Pharmaceutical industry: Used for manufacturing drug packaging containers and the like.


IV. Technology Development Trends


  1. Intelligence: With the development of Industry 4.0, extrusion blow molding machines will become more and more intelligent, realizing functions such as remote monitoring, fault diagnosis, and automatic optimization of production.

  2. Energy conservation and environmental protection: Adopt more energy-saving heating and driving technologies to reduce energy consumption; at the same time, optimize the production process to reduce the rejection rate and reduce the impact on the environment.

  3. High speed and high efficiency: Continuously improve production speed and efficiency to meet the rapidly growing demand for plastic products in the market.

  4. Large-scale and precision: To meet the needs of large plastic products and high-precision products, extrusion blow molding machines will develop in the direction of large-scale and precision.


In conclusion, Extrusion Blow Molding Machine plays an important role in the plastic processing industry. With the continuous progress of technology, it will provide more high-quality, efficient, and environmentally friendly plastic product production solutions for various industries.
