1. What Is A Bottle Blowing Machine?

A Bottle Blowing Machine is a device used for blowing plastic bottles for liquid packaging. It is used to blow plastic bottles of different capacities and designs with less than a 0.1% of rejection rate.It uses a PET preform material for the production of plastic bottles.A Bottle Blowing Machine uses a specialized PLC system which is very easy for the user to operate for blowing bottles.

First of all, the preform is heated to form a soft jelly liquid then the air is blown into it. Then the heated plastic attains the shape of the mold cavity of the machine to produce a high-quality plastic bottle.

5. How Does A Bottle Blowing Machine Works?

A Bottle Blowing Machine inserts the preforms into the heating oven and softens them at the required temperature.Then it is driven to the mold cavity with specific capacity and size.

The compressed air inflates the processed preforms to attain the shape of the mold cavity.When it cools down the mold opens, ejects the bottle, and trims the excess plastic from the neck of the bottle.  Its work includes three main steps one after another.

In the first step, the preform stretches on adjusted temperature.Then in the second step, it blows the preform to overall distribute the material for the second blow.At the last second blow blows the preform in the shape of the mold cavity to form a bottle.These three steps must be one with proper concentration to achieve high-quality products.

6. How Much Air Pressure Is Required In Your Bottle Blowing Machine?

The air consumption of the Bottle Blowing Machine depends upon its capacity such as ranges from 2.0m3/minute to 10m3/minute.The maximum air pressure requires for your machine is 3.0Mpa and the Minimum air pressure required to blow bottles is 1.0Mpa.

10. What Is The Unit Production Rate Of Your Bottle Blowing Machine?

The unit production rate of bottles Blowing Machine is the number of bottles it produces in an hour.It always depends upon the volume and the size of bottles you are going to manufacture.Generally, it’s about 2000 to 10,000 bottles per hour.

11.What Are The Factors Which Affect The Production Rate Of Your Bottle Blowing Machine?

The following factors can affect the production rate of the Bottle Blowing Machine.

  1. The temperature of preform affects the shape, surface finish, joint strength, and cooling time directly.Too much higher and lower temperature can affect it badly.Use appropriate temperature for preform heating.
  1. Inappropriate blowing speed and pressure also affect the production rate of this machine.
  2. The blow-up ratio must be developed properly.A very small blow-up ratio will increase preform consumption.The too much higher blow-up ratio will thin the product and the shape will become worse.
  1. The mold temperature and the size of the preform must be chosen according to the properties of the product.
  2. Give proper cooling time to the product to maintain the air pressure and stability of the bottle.
  3. The blowing and molding cycle of the Bottle Blowing Machine Must be short enough to prevent defective products.
