The plastic bottles and other hollowed out objects that are
found in daily use are auxiliary production results of plastic molding
processes. The process of development of such hollow containers especially made
of either soft or hard plastics is called the Pet Stretching method. The method is an offshoot of the plastic
industry and it accounts for a sizeable portion of the total with its prime
customers being companies that sell their product mostly liquid, in plastic
containers of all sizes and volumes. The material that is most often used in
pet forming is thermoplastics and this is due to the materials unique ability
of being easily pliable on heating and then returning to the solid state upon
cooling. This makes it almost the best option for producing pet jars and
bottles.
PET or Polyethylene Terephthalate is a form of thermoplastic
under the polyester family that is used in synthetic fibers and especially in
liquid containers. The PET bottle was introduced in the early 1970s and since
then has replaced glass bottles as liquid containers due to its durability and cost
effective ability. The manufacture of the PET bottle is of two varieties: the
first procedure is the general procedure that involves a single Pet preform machine in which every step
of the manufacturing process has been installed. It is one of the easiest methods
of production that is widely used as it significantly lowers the time, energy
and manpower consumption thus effectively reducing costs. The process is generally
used by PET bottle manufacturers where slight lack of precision is not a huge problem
and mass production is the aim along with lower costs such as in the production
of soft drink bottles. The second method of production is a bit expensive and yet
is precision based; it includes the PET molds which are shaped into containers
like test tubes and burettes which rely almost entirely on accuracy. This
involves a PET preform mold that is shaped using Injection Stretch Blow molding
process in which liquid PET is injected, forged and then cooled. Every step is
taken up separately allowing for better control on the accuracy yet the same
processes make it time taking.
The
internet has hundreds of online Pet preform
machine makers and suppliers yet reliability could be a huge factor in
determining one’s choice. Sino-Holdings Group is one such highly reliable as
well as a reputable brand in the global market that is known for its quality and
service. As a well known Pet preform machine supplier, Sino-Holdings Group use the best in class materials and
the technicians have the option of using high speed and precise instruments developed
by Japan. The company specializes primarily in manufacture of a huge range of PET
based products and plastic injection products.
