Automatic Blowing Machine- An Ultimate FAQ Guide.

Here is a well-researched and all-inclusive FAQ guide for Automatic Blowing Machine.This ultimate guide contains the features, specifications, components, and a lot more about Automatic Blowing Machine.
Let’s start it！

What Is An Automatic Blowing Machine?

An Automatic Blow Machine adopts blowing technique to blow plastic bottles of different shapes and sizes.For example; beverage bottles, pesticide bottles, and water bottles, etc.The blower of an Automatic Blowing Machine blows the preform into the required shape and size.The preform is as a raw material in the Automatic Blowing Machine.

The blowing machine drives the preform from different stages; pre-blowing, high blowing, stretching, and exhausting the bottle.An Automatic Blowing Machine can be one step or two-step blowing machine.It does not require manual operation. It uses an advanced PLC control system.The production process used in an Automatic Blowing Machine is known as blow molding.An Automatic Blowing Machine offers fast and high-quality performance to manufacturing plastic bottles.

What Is The Working Principle Of An Automatic Blowing Machine?

An Automatic Blowing Machine works on the principle of specifications of PET material.It uses preforms made up of plastic pellets.The two-step blowing machines are most commonly used for the production of plastic bottles and other packaging materials such as beverage packages.

It is a widely used Automatic Blowing Machine because of its simple structure and it is convenience to use.
It is also known as a servo blowing machine as it uses a servo motor and has high output.An Automatic Blowing Machine is a feed by the preform that is transferred to the rail.They slide down to the specified position, then a gripper fills down the perform to complete the automatic loading process.

Next is the stepping system, which is used to link every system in the process of Automatic Blowing Machine.
It is also called a transmission system.It contains two parts the perform base and the transmission chain.
The transmission chain is used to carry perform to the blank and then drive it through the heating system and blowing system.

The heating system is responsible for heating the preforms at a specified temperature and then helps it to blow.
A heating system contains a heating tube, a cooling system, and a reflector.The preform is heated by heating ovens.Heating ovens use infrared lamp tubes after that the reflector sheet heats the preform uniformly from both sides.

When the preform is heated and the system is chilled.It cools down the bottle mouth to avoid preform expansion.The heated preform is blown by the blowing system to acquire the desired size and shape.The blowing system contains a stretching device and a clamping system.In the next step, the blown product (typically a bottle) is taken out from the mold by using a gripper into the container by air.
