Parison reference height is the height of the bottle body height obtained by multiplying the coefficient,the height of the bottle is generally 92%to 95%.In order to ensure good transparency of the bottle,a melt parison mold after filling,the temperature was quickly lowered to less 145℃,but than the glass transition temperature of the polyester material(82℃)higher and closer to the glass temperature,the higher the transparency of blown bottles.Parison mold cooling water temperature up to 10℃~35℃,for rapid cooling of the parison,it will take a liquid or gas to the mandrel continuous cooling,where cool air mandrel can have a more uniform temperature distribution,the air pressure is generally about 1 MP a.2,the melt temperature of the preform during in jecti on The melt temperature is an important parameter PET preform molding to note.From the viewpoint of equipment,screw design have a greater impact on the PET melt,mix and melt temperature.
PET injection to the use of low shear,low compression ratio(about 2/1)of the screw,made longer feed section,at ransition section and a metering section made shorter.Barrel temperature of the device a greater impact on the melt temperature,barrel temperature increase will reduce the intrinsic viscosity of the PET melt.Barreltemperature had a significant effect on the parison transparency,improvecylinder temperature can improve the transparency of the parison.For example,when a barrel temperature of 280℃,the corresponding melt temperature of 290℃,can ensure optimal transparency parison.The barrel temperature increasedoes not improve further transparency.Lower barrel temperatures,anappropriate increase in screw speed to clap gate temperature,small quantitiescan improve the transparency of the parison.However,due to the hot runnersystem melt through time is short,to a lesser extent the temperature of theparison transparency improvement.Increase the injection pressure,i.e.,when the injection rate,the heat generated when high shear melt through the nozzle,the melt temperature is significantly improved.

But in recent years,part of the beer business by improving the performance and technology of the United States,Japan and other countries and Europe We have begun to use PET bottles are also a few companies are developing PET beer bottles,such as Zhuhai Zhongfu,Shanghai Zi Jiang,Zhejiang Huangyan three rounds,Xiamen Hua Kemao packaging company,vigorously develop their own intellectual property rights of co-injection stretch blow molding technique,coating technology,multi-blended barrier technology has made some achievements in the production and promotion of PET beer bottles.However,the present data show that beer production costs and cost recover sing PET bottle packaging than glass bottles,and beer companies to switch to PET bottle packaging,the need for many of the existing equipment transformation,such as bottle cleaning device,which It is bound to increase investment.In addition,people's consumption concept is one of the factor shin der PET bottles for beer packaging a large number compared to PET bottled beer drinking,temporarily consumers may prefer to bring glass bottles of beer bold and happy.So,on the whole,PET beer bottles still in its infancy,them arket share is very low,promote the use of yet more difficult.1.Enhance the direction of improvement of heat resistance Hot filling process,PET bottle to go through the UHT(instantaneous heating to 120~140℃,travel tens of seconds),and then lowered to filling temperature(85~90℃).After filling and capping,the bottle upside down or lie down to about 30 seconds in order to cap and neck and the body parts of the sterilization process with temperature.Bottle stay for some time at high temperature(30 to 120 seconds)and then into the cooling passage,the PET bottle segment is cooled to 34~38℃,subsequent PET bottles labeling,packing,etc.,after packaging.Thus,the hot-fill PET bottle technology requirements better heat resistance,over come the effect of temperature on the shape of the bottle.For generic products,high temperature(85~90℃)PET bottle volume shrinkage should be control led at 1%to 1.5%.2.improve barrier proper ties Although the gas barrier PET is much higher than polyethylene,polypropylene,polystyrene and other plastics,but for beer,liquor,perfume,etc.

Bottle wholesale acrylic jars plastic supplier
Pet Bottle Manufacturers Maki packaging co., Ltd was founded in 2002, is the production of glass bottles, plastic bottles and canned drinks detection machine expert senior business. Our test machine is not in direct contact with the object occurs in the detection, and therefore were seized deterioration phenomenon does not occur in the detection of the way. Detecting the way, if the foreign body is detected will automatically be removed. The use of a more sophisticated and fast image analysis system to detect machines that can replace human to save costs, so many advantages allow customers to save costs and improve production efficiency.
Especially in the beverage industry, the production speed of the production line of 600 or 800 per minute, in this industry, many companies are in the application of foreign testing machine, and now South Korean domestic large enterprises such as Hyosung and Lotte are using our detection machine.
