Hot Wire Bottle Cutter For Pet Bottle Testing
Jan 8, 2013
In the manufacturing of PET Bottle take one bottle as a sample, there is need to cut the PET bottle into pieces as per requirement and take the weight of PET Bottle segments individually to ensure that the thickness and weight is as per standard, and after the test if it is ensured that the product manufactured is as per standard then only can manufacturing be approved.

In the manufacturing of plastic Bottles different types of plastic polymers are used according to the physical and chemical property of polymer. There are different types of polymer available with different physical and chemical property which is used in the manufacturing of Bottle according to the demand customer.

High Density Polyethylene (HDPE):- This material is economic, impact resistance and provide a good moisture resistance. HDPE Bottle is used to store acids and caustics while it can not be used to store solvents. HDPE is translucent and flexible. With the help of color addition the polymer can be make opaque. The polymer can be used for silk screen decoration. Bottle made from polymer store the products below freezing point and upper temperature limit is 160?F. It can not be used to store the product below atmospheric pressure.

Low Density Polymer(LDPE):- LDPE is less rigid and more translucent than HDPE. The polymer is good for squeeze application. Compare to HDPE, LDPE is more expensive.

Polyethylene Terephthalate (PET or Polyester):- This is generally used for the storage of carbonated beverage, water bottle and food products. The polymer is used to make alcohol and oil container. This is also good for chemicals excluding acetones and ketones and has good impact resistance and tensile strength. The maximum temperature limit for the PET bottle is200?F (93?C).

Polyvinyl Chloride (PVC):-It has good resistance to oil, so PVC containers are used to store salad oil, mineral oil and beverage. The polymer has low oxygen transmission. It has  excellent resistance  to most gases.

When high density polyethylene was introduced. They quickly became popular among manufacturers and customers due to their light weight and low production cost compare with glass bottle. Now a days all kind of beverage industries, water industry use plastic bottle. Excluding wine and beer industry the food industry has fully  replaced the glass bottles.

Polyethylene Terephthalate is broadly used for carbonated beverage water bottle and many food products. PET is good chemical resistance and is very good alcohol and oil container. It has good tensile strength and high degree of impact resistance. The orienting process serves to improve gas and moisture barrier properties and impact strength. The material does not provide resistance to very high temperature approximately-max tem. 200?F(93?c).

In the manufacturing of PET Bottle take one bottle as a sample, there is need to cut the PET bottle into pieces as per requirement (3 pieces, 4 pieces, 5 pieces) and take the weight of PET Bottle segments individually to ensure that the thickness and weight is as per standard, and after the test if it is ensured that the product manufactured is as per standard then only can manufacturing be approved.

For the test performance and more precisely to cut the bottle into piecesHot Wire Bottle Cutter is used widely. To cut the bottle into pieces (3 pieces, 4 pieces, 5 pieces) respectively Two wire, three wire and four wire Hot Wire Bottle Cutter is used respectively. The instrument contains metallic wires which is adjusted parallel to each other to cut uniform cross section of bottle , these wires are heated up to desired level which is according to the thickness of bottle, Then with the help of these heated wires PET Bottle is cut and with the help of digital weight balance weight of each individual segment is noted and then analyzed.
