1. Working principle of semi-automatic blow molding machine

A semi-automatic blow molding machine is a mechanical device used to manufacture plastic containers and utensils. It mainly includes the following parts: preheating furnace, blow molding head, mold and control system. Its working principle can be briefly summarized as the following steps:

Raw material preheating: First, plastic granules or granules are added to the preheating furnace, and melted into a plastic state by heating. The preheating furnace adopts advanced heating technology to ensure that the raw materials become easy to process at just the right temperature.

Mold Design: According to the shape and specification of the required product, design the corresponding mold. Mold is the key to the formation of plastic products, and its precision and quality directly affect the appearance and performance of the final product.

Blow molding: The preheated plastic raw material is delivered to the blow molding head through the feeding system. The blow molding head will blow and cool the plastic under the action of the mold, so that it can be formed quickly. This stage requires certain operational skills to ensure the quality and consistency of the product.

Product demoulding: After the molding is completed, open the mold and take out the finished product. Then carry out necessary follow-up processing, such as trimming, punching, etc., to meet the needs of different customers.

2. Second, the advantages of semi-automatic blow molding machine

Efficient production: Compared with manual blow molding and automatic blow molding machines, semi-automatic blow molding machines have achieved a better balance in production efficiency. It combines the operator’s skill with the automation of the machine, which can increase the production speed and reduce the production cost to a certain extent.

Flexibility: The semi-automatic blow molding machine is suitable for small and medium-scale production, and can quickly change molds according to customer needs to produce plastic products of different shapes and specifications. This flexibility enables enterprises to better meet the diverse needs of the market.

Energy saving and environmental protection: Semi-automatic blow molding machines consume less energy than fully automatic blow molding machines in the process of raw material heating and product molding. In addition, by optimizing the production process and reducing the scrap rate, it is also conducive to reducing resource waste and environmental pollution.

Low labor cost: Although compared with manual blow molding, semi-automatic blow molding machines require more operating skills, but compared with fully automatic blow molding machines, part of the labor cost is still reduced. Operators only need to master basic operating skills to operate the equipment without excessive professional knowledge.


3. Three, the application prospect of semi-automatic blow molding machine in the plastic processing industry

Packaging industry: Plastic packaging products are one of the main application fields of semi-automatic blow molding machines. Plastic bottles, plastic containers, food packaging boxes, etc. are widely used in food, daily chemical, pharmaceutical and other industries. The flexibility of the semi-automatic blow molding machine enables manufacturers to quickly adjust the production line according to the needs of different products and adapt to the constant changes in new packaging in the market.

Industrial use: Semi-automatic blow molding machines are also widely used in industrial purposes, such as auto parts, chemical containers, liquid storage barrels, etc. In the industrial field, there are high requirements for product quality, durability and cost. Semi-automatic blow molding machines can meet these requirements through flexible production capacity and optimized production process.

Household items: Plastic household items are also an important application field of semi-automatic blow molding machines, such as plastic buckets, plastic chairs, plastic trays, etc. These products are widely used in daily life, and the high-efficiency production and diversified production capacity of semi-automatic blow molding machines can meet the needs of the household goods market.

Medical devices: With the continuous advancement of medical technology, the application of plastics in medical devices is becoming more and more important. Semi-automatic blow molding machines have certain advantages in the production of medical supplies, such as medical syringes, infusion bottles, etc. These products have strict requirements on the production process and product quality. The semi-automatic blow molding machine meets the needs of the medical device industry through a stable production process and high-quality products.

Semi-automatic blow molding machine is a kind of equipment widely used in plastic processing industry, its working principle is simple and efficient. By preheating plastic raw materials and blowing and cooling under the action of the mold, plastic products of various shapes and specifications can be quickly manufactured. Compared with manual blow molding, semi-automatic blow molding machines improve production efficiency and reduce labor costs. Compared with fully automatic blow molding machines, it is more flexible and suitable for small and medium-scale production, and it is energy-saving and environmentally friendly. It has broad application prospects in the fields of packaging, industry, household goods and medical equipment. With the advancement of technology and the improvement of environmental awareness, semi-automatic blow molding machines will continue to optimize and play an indispensable role in the plastics processing industry in the future.
