    Blow Molding Machine Safety Operation Rules
    Here are some Safety operation rules for Blow molding machine: <1> Before starting each shift, add lubricating oil to each moving part. (manipulator, manipulator guide rail, mold opening and closing guide rail) <2> The swing arm 3-4 days/time. The large chain and small chain of the heating machine one time/month. Always check whether the main engine reducer and the heating machine reducer are short of oil. The main engine bearing can be every 3 months per time. The above suggestions are only for semi-autimatic blow molding machine. The automatic blow molding machine has automatic lubrication oil device. <3> Before production, check whether the moving parts are firm, whether the screws are loose or falling off, especially in places with strong impact force, and whether the belt transmission part is abnormal. <4> When start machine, start motor first, after 30 seconds to start the heating part to prevent voltage fluctuations.Turn on cooling water before starting the heating. <5> Check whether each emergency stop switch, safety door switch, and detection switch of the protection device are normal. <6> Check the peform in, preform out and insert preform part. <7> Check whether the l

    The Advantage of PET Plastic Bottles
    PET is one of the most popular material in packaging fields. PET plastic bottle is widely used in water, carbonated drinks, pharmaceutical and personcal care applications. What is the advantage to use PET Plastic Bottles? 1. Easy Transportation & Flexible Design : PET plastic bottles require less protection during transportation. This can help manufacturers save on cost with simple package. Furthermore, PET bottles has endless possibilities when it comes to design. Only change the bottle moud. It can get different form and size. Also bottle mould price is not high. This enables factories to create their own identity and come up with unique designs. 2. Better Hygiene: FDA has cleared PET plasti bottles for single and repeated use. Regulatory authorities has tested the new and re-used PET bottlesfor harmful substances. It shows ir is hygienic and incredibly resistant to micro-organisms. Moreover, it will not chemically or biologically degrade as it does not react with food

    PET Preform Analysis
    PET Preform is commonly used for food & beverage, cosmetic, pharmaceutical & liquor bottle. Application for water bottles, CSD, edible oil, food packaging, juice and alcoholic beverages. PET preform are made by injection molding of polyethylene terephthalate, which is the most common thermoplastic polyester. PET is strong, stiff, hard, and dimensionally stable material. It is resistant to water, gas, and all the chemicals except alkalis. PET is colorless and highly transparent. It is popular in Food and beverages industries. PET products with the advanatge of light weight, long shelf life and easy to handle. It is also popular in healthcare and cosmetics industries. Demand for pack weight reduction, rise in consumption of carbonated soft drink, and new product developments are some of the major drivers for the growth of PET preform market. Stringent government regulations on usages of plastic products and unavailability of recycling facilities are major restraint for PET preforms market. PET preform Market Classfication:

    PET Plastic Bottle Quality Factors
    What affect PET plastic bottle quality? Preform quality Recycling materials should not exceed 10%. The number of recycling time should not exceed two. Preform cools for more than 48 hours. Storage time can not exceed 6 months. We can not mix different production dates preform, especially preforms with too long storage time PET Plastic Bottle Machine Pre-heating The PET Plastic Bottle Machine heating temperature usually set at 85-120℃. Transparent preform should be higher, and the colored preform should be lower. Too high or too low will cause product defects, such as tearing, white fog, etc. Each area has indepent temperature controller. The output power has a great influence on the heating preform, which controls the heat output of the entire oven. When the machine turns off for a long time and turns on again, the initial output power should be set higher accordingly. Then gradually reduce to the normal state. The output power is generally about 80%. PET Plastic Bottle Machine Pre-blowing PET Plastic Bottle Machine Pre-blowing makes the preform take a genral shape and increase its longitudinal strength by the stretching rod. If the pre-blowing position is advanced, bottle bottom will be skewed , thin, uneven and white. Inversely, bottle center will be thic

    PET Plastic Bottle Blowing Machine And Extrusion Blow Molding Machine
    The difference between PET plastic bottle blowing machine and extrusion blow molding machine: PET plastic bottle blowing machine is mainly for PET bottles. The semi-automatic custom made PET blowing machine can do some simple PP bottles, like the feeding-bottle. Extrusion blow molding machine is a device for blowing hollow plastic product, the material like HDPE, PP, PC and PVC. PET plastic bottle blowing machine has 2 types, two-steps and one-step. The most in market is two-steps. Injection machine makes the preforms from material, then PET blowing machine blow the preform to bottles. The one-step blowing machine is to inject molding at one time in same machine. Extrusion blow molding machine also named based model forming. The resin through the loader to barrel, then push to die head mould. After cooling becomes to bottles. Choose your right blowing machine, choose Winiber!

    Bottle Mineral Water Filling Machine Installation and Commission Steps
    The bottled mineral water filling machine is a self-priming filling of the leather tube, and the leather tube is placed in the material storage barrel. Under the action of the cylinder pulling the piston rod, the material enters the metering cylinder through the self-suction tube and the three-way lower check valve, and then The piston pushes the piston to push the material out, and the material enters the container through the three-way upper check valve, the leather tube and the filling head, and the amount of the filling is determined by the magnetic control switch controlling the stroke of the cylinder. Installation and commissioning of bottled mineral water filling machine 1. Install and then debug, read the instructions carefully before commissioning, and prepare the tools used. 2. After the installation, brushing machine and the rinsing machine are installed, the filling track and the bottle receiving tray are leveled, the liquid storage tank is filled with materials, and all the electrical switches are in the closed position. 3. Fill the container into the tool box, connect the external power supply, the power socket must be a three-pin socket, and have a reliable grounding wire to prevent the chassis from leaking power, turn the machine power switch to ON, and the power indicator light. 4.

    How to Operate Bottle Blowing Machine Safely
    Here we introduce some points to help customers to operate bottle blowing machine safely. 1. Before each shift, blowing part each unit must be lubricated once. (manipulator, manipulator guide, open and close mold guide) 2. The swing arm can be added once (3 - 4) days. Heating machine large chain, small chain can be once a month. Check the main engine reducer and heating machine reducer for lack of oil. The main bearing can be added once every two to three months. 3 . Before production, check if the moving parts are fixed and whether the screws loosen and fall off, especially if the impact force is strong, and whether the belt drive part is abnormal. 4 . Check whether high and low pressure gas source, power source and water source are normal. 5. Check each emergency stop switch, safety door switch, protective device detection switch is normal. 6 . Check the warming head into the embryo, if the embryos are working properly. Insert the embryo if not in place to adjust the embossing device nut. 7. Check the lamp for damage and break. Replace it in time. 8 . Check whether each pneumatic component leaks and the action is sensitive. 9. Whether the triplex is abnormally leaky, whether it is blocked, and whether the water in the cup is too full. 10. If there is an abnormality in the solenoid valve of the blowing machine, it must be cleaned in a timely manner. 11. When the high and low pressure gas source switch is turned on, it must be operated slowl
