PET Bottle Blow Molding
Polyethylene terephthalate (PET) bottle blow molding press compared the formation of pre-production shall be divided into injection blow molding frame (frame injection blow for short), and extrusion stretch blow molding (extrusion blow stretching, for short). In most methods of molding, and to stretch blow injection cutting edge designs is easy to control, high efficiency, fewer waste and common defects.
PET bottle blow molding shall be classified into 3 categories; there is a compression bottle, for example filling carbonated beverage bottles and another for non-pressure cylinders, for example filling of water, tea, bottles of oil. Combine tea drinks bottles is polyethylene naphthalate ester (PEN) modified cap molds or ester compound and thermoplastic PET bottles aryl, classification is a warm bottle, you can heat above 80, are cold bottle bottle without need for heat tolerance.
As cutting edge designs advances and scale of production, glass cap moulds increasing degree of automation machinery, productivity is increasing. Production team the ability to increase production over the final multiple thousand bottles per hour developed to make tens of thousands of bottles per hour. Also from the development regarding the final operating manual button style, for now all controlled by the computer, greatly reduces the difficulty regarding the operation regarding the process, increasing the stability regarding the process.
Acme prepares bottle blow, first slice of injection molding of PET preforms, as it requires twice the proportion of recycled fabric can not be too high (5%), recovery times can not be higher than doubled, and molecular mass and viscosity is not very little (31000- 50000 molecular weight, intrinsic viscosity 0.78-0.85cm3 / g). Preform injection molding can only be stored for higher than 48 hours to use. Do not be left without heating regarding the preform, to be stored higher than 48 hours prior to being re-heated use. Preform storage time should not exceed six months. PET preform fabric depends largely on the return regarding the advantages and disadvantages, inflation should with no problems select, and fabric with no problems stereotyped and creates the process fair preform molding. The experimental conclusions display that the similar to viscosity fabrics PET preform molding, raw fabrics imported from blow molding local trade, the similar to batch of preforms, the production of different dates, blow molding should possibly be very different. Preform determines the merits regarding the ease of blow molding process, the requirements regarding the preform is pure, transparent, no impurities, no halo of color around the injection spot and the length regarding the right place.
