Pet Bottle Manufacturing Processes In Pakistan

 

How is plastic pet bottle manufacturing done? There are many methods, such as blow molding, extrusion molding, and reconditioning, but most bottles are generally formed through extrusion molding. In extrusion molding the plastic bottle is formed directly from a solid injection mold, rather than being a per-manufactured plastic product. This is the most common method and the most economical. However, it also results in the highest number of waste products and parts.

Reconditioning involves returning plastics to their original state. In doing this you can either make packaging easier or use recycled plastics to create new packaging. It can be used to help reduce packaging waste and to reuse packaging that would otherwise be thrown out or sold. Reconditioned bottles can even be used to create brand new plastic packaging. This is one of the most important plastic pet bottle manufacturing process to help make packaging easier.

Here, the plastic is heated up to between 150 degrees Celsius and 200 degrees Celsius depending on the material being used. This is called 'Pre chilling' and the reason for doing this is so that the plastic does not get too hot while it is in its initial phase of forming.

 

Plastic Bottle Manufacturing Process

Next the plastic is placed in a mold which is called a casting. There are two types of molding to use, those that use a single large mold and those which use multiple smaller ones. The first type is used when making the thicker, more durable polyethylene terephthalate (PET) bottles. The second type is used for the less durable but lighter weight polyethylene urethane (PEU) bottles. The pet bottle need to be put into the mold using the blow press or a pressurized manual.

The plastic bottle manufacturing process is complete only after the material is cooled down in the cannula. Here, the material is put into the injection mold that will be used to make thousands of identical plastic pet bottle. This is called as the 'Injection mold' process. The next step involves injecting the cooled material into the mold. However, this process is called as the 'pilings' injection method. This means that the injection mold can either be open ended or closed ended depending on the material being used and the desired shape.

One of the most common plastic pet bottle is the poly carbonate resins article. The poly carbonate resins article is made by injecting molten plastic resins into the canal in the blow mold machine. The material to be melted is heated to a specific temperature. Once the material reaches the melting temperature, it is allowed to cool under pressure. Here, the poly carbonate resin comes out as a hard solid piece.

Another common plastic bottle manufacturing process is the preform manufacturing process. In the preform manufacturing process, hot plastics are fed into the cannula. After it is filled with the materials, the process involves the injection molding machine to manufacture thousands of identical bottles. This is known as the 'Preform' mold manufacturing process.

Now, you have known about the different kinds of plastic pet bottle. These are manufactured in various ways. They can be made using manual methods, automatic machines or in the preform mold making method. Whatever may be your manufacturing process, the important thing is that you should protect the environment from the harsh effects of plastic bottles.

There are some tips and safety precautions that must be followed by all the manufacturers. Manufacturers must ensure that the bottles are not exposed to the atmosphere for a long period. Manufacturers must make sure that the plastic is properly cooled before exposing them to air. Plastic is known to break down when it is exposed to air. So, you should take care to place the plastic bottle blowing machine in a safe place, before blowing the plastics. Make sure you read the instructions on how to operate the plastic pet bottle blowing machine properly, before proceeding.

There are plastic manufacturing companies which supply equipment’s like injection mold kit and heat treating ovens to the manufacturers like Indus Printing. You can also buy the containers separately. In some cases, these containers come along with the kit. Some other companies offer a separate shipping for the pet bottle.

Plastic Bottle manufacturing process may be done in various steps. The first step of the entire process is the mixing or whipping of the compound. This process may be done post-manufacturing, once the bottles are ready to be shipped. The second step includes the attachment of the mold material. Heat treatments are also involved in this stage.
