How Blow Molding Machinery is used for Producing Pet Bottles?

The 20th century witnessed the rise of plastic industry. It steadily replaced glass wares.  Plastic utensils were light weight, flexible and durable. These advantages made plastic PET bottles a household name.  Even now they’re very popular in the market.

These bottles are produced by Blow Molding Machinery. The production process goes like this.  The basic raw materials are Ethylene Glycol and Dimetyl Terephthalate. They are mixed together in the initial stage. Then the mixture is melted to form a liquid solution. The next step involves the plastic mold injection machinery. The liquefied material is molded to shape of the test tube. The bottle cap maintains the thread on the top.

A conveyor takes the tubes to the heater. Conveyor generally uses chain to nozzles in this step. The tubes are heated and the tubes become highly supple. Needless to say, this is the ideal state to form the PET bottles. The last step involve shot air, which is used to give tubes their final shape.That’s how blow molding equipments are used to manufacture PET bottles.

The next step is quality testing. This step is very important in the manufacturing process. It involves numerous tests. The tests ensure that the final products are ready to hit the market shelves.  Some common tests are top load tests, pressure tests, soil test, transparency and torque test. If the product passes all the above mentioned tests, it is put up for sale.

You can purchase Shuttle Blow Molding equipments, Long Stroke Blow Molding, Extrusion Blow Molding and plastic mold injection machinery through online sellers. There are many reliable sellers on web. They also offer amazing discounts on their products.

So, these are some crucial factors in purchasing a suitable Extrusion Blow Molding machine or any other types of molding machine. The most important thing is that you consider your needs and budget before making a choice.

Extrusion Blow Molding process and its safety measures

Extrusion blow molding

Extrusion blow molding is a procedure through which the plastic is melted and extruded into a hollow tube. Later the parison is captured by closing it into a cooled metal mold. Then air is blown into the parison, expanding it into the shape of hollow container, bottle or any other part. When the plastic get properly cooled, the mold is opened and ejected from the part. The most common extruded materials are Acrylic, Polyester, Polycarbonate, PVC, Polystyrene, Polyethylene, etc. The two variations of Extrusion Blow Molding are Continuous and Intermittent. It is again divided into sub categories that are as following:

Continuous extrusion equipment

  • rotary wheel blow molding systems
  • shuttle machinery

Intermittent extrusion machinery

  • reciprocating screw machinery
  • accumulator head machinery

Safety Precautions for extrusion blow molding are:

  • Make sure to keep machine and floor oil free
  • It is necessary to keep machine and floor free of pellets
  • Never go over or under machine guards
  • When hydraulic pumps are running don’t try to climb between the tie bars
  • Keep in mind to wear adequate noise protection
  • The extinguisher should be on 75 feet, so know location of portable fire extinguishers
  • Make sure to wear appropriate foot and eye protection for safety point of view
  • It is recommended to not to wear soft soled shoes

All these technical process require lots of practical and theoretical knowledge to come up with the final product through the large production. Several highly experienced and certified companies are located in market offering top class services to the customer companies and make sure to meet the need accordingly. People who are looking for such service need not to get worry as the experienced blow molding companies are there to help you.
