Brief Introduction of Bottle Blowing Molding Machines

What is a bottle blowing molding machine?

The definition of a PET blow molding machine is a production machine used to make bottles of different shapes and sizes. Its working principle is not complicated: relying on the applied air pressure, the blow molding machine blows air into the heated preform and sets it with a specific mold wrapped around it.

The production process of the bottle blowing molding machine

The first step, warm up. Heat the embryo body part of the PET preform to a suitable molding temperature, and keep the inner and outer walls of the embryo body heated evenly. Because the mouth of the bottle is shaped, no heating is required. Therefore, the neck of the bottle needs to be cooled during the heating of the embryo body.

The second step is blow molding. The uniformly heated preform is sent to the blowing mold through the chain, and the sterile high-pressure air is blown into the preform through the middle of the mandrel for hoop stretching, so that it is inflated until it is close to the mold wall, and then cooled.

The third step is demoulding. After blowing, the machine starts to vent the mold.

The fourth step is to send. The formed PET bottle is sent to the bottle unloading station through the conveyor belt, and is pulled up and blown out by the bottle unloading cylinder. If it is in the blow-stick-fill-cap machine produced by Tech-Long, it will be sent to the next machine for packaging.

Features of blow molding machine

Plastic hollow containers are widely used in the beverage, medicine, cosmetics, food and chemical industries due to their light weight, low price, high safety and other characteristics. It has attracted more manufacturers to choose plastic containers to replace the previous glass containers. The most advanced equipment, molds and raw materials in the plastics industry are all displayed in front of us one by one. New technologies and new applications are emerging one after another. Looking at the field of plastic hollow molding is also fruitful. With the soaring price of oil in the world, the price of plastic raw materials is also high. The development of alternative products with low energy consumption and low raw materials is also one of the market trends.

How to choose a blow molding machine

• Strictly check the quality issues and check the safety performance and technical performance of the product, which is the most important step in the purchase process.
• Understand the after-sales service situation. Products with guaranteed quality must have good after-sales service. When choosing, you can pay more attention to the after-sales service situation of the merchant.
• When choosing a blow molding machine, everyone must carefully check the relevant technical documents, such as instructions for use, operating instructions, certificates of conformity, packing lists, software operating instructions, etc., and perform standardized operations in accordance with the instructions.
• Understand the quality management level of the production enterprise. For manufacturers that have passed the ISO9000 quality management system certification and safety certification, the performance and technology of their products are trustworthy.
