Definition of Injection Mold The mold used in plastic injection molding is called injection mold. The injection mold can make complex shape, high dimensional accuracy or with inserts plastic product at one time. The injection mold quality has a great influence on the plastic product quality. Structure and Composition of Injection Mold Main Formed Parts Injection Mold consists of core, cavity, screw, inserts and so on. 2. Gating System It is a channel that leads molten plastic from the nozzle of the injection machine to the closed mold cavity, usually consisting of main runner, branch runner, sprue gate and a cold slag. 3. Guiding Fitting To ensure the movable plate and the fixed plate can be accurately aligned when the movable plate is closed, the guide fitting plays the role of guiding and positioning. It is composed of guide pillar and guide sleeve, and some molds are also equipped with guide fittings on the ejector plate to ensure the smooth and reliable operation of the demolding mechanism. 4. Demoulding Structure There are many structural forms to demould. The most commonly forms are ejector rod, push pipe, ejector plate, rotary ejection and pneumatic ejection. Generally, it consists of ejector rod, reset rod, the ejector rod fixing plate, the ejector plate (ejector ring) and the ejector plate guide pillar / guide sleeve, etc. 5. Core-pulling Mechanism For plastic parts with side holes and side concave, before being ejected and demoulded, the sliders must be separated by side core pulling (lateral parting) before they can be demolded smoothly. 6. Mold Temperature Control System To meet the mold temperature requirements, a mold temperature adjustment system is required. Such as cooling water, hot water, hot oil, steam, cold air and electric heating systems to adjust the mold temperature. 7. Exhasut Air System To discharge the gas from mold, the exhaust groove is oftenly set at the mold parting surface. The gap between the push rods and other movable parts also play the role of exhaust gas. 8. Other Parts To complete the mold structure, it also need fixed plate, movable/fixed die plate, support pillar, support plate and connecting screw etc.

According to air compressor principles, there are piston compressor, rotary compressors (turbine, water ring, turbine) compressors, axial compressors, jet compressors and screw compressors, etc. The most widely used are piston compressor. How are piston compressors classified? ♦According to the cylinder position: (1) Horizontal compressor (2) Vertical compressor (3) Angle compressors ♦According to the number of cylinder sections: (1) Single-stage air compressor : the gas compressed one time in the cylinder (2) Double-stage air compressor: the gas compressed twice in the cylinder (3) Multi-stage air compressor: the gas compressed multiple times in the cylinder ♦According to the arrangement of the cylinders: (1) Tandem compressor: same shaft with several cylinder (2) Parallel compressor: everal cylinders in parallel on several shafts (3) Duplex compressor: a multi-stage compressor composed of a series and a parallel type (4) Symmetrical Balanced Compressor: The cylinders are arranged horizontally on both sides of the crankshaft where the crankshaft journals are 180 degrees from each other, and are arranged in an H-shape, and their inertial forces can basically be balanced. (Large compressors are all headed in this direction). ♦ According to the compression action of the piston: (1) Single-acting compressor: the gas compressed on one side of the piston (2) Double-acting compressor: gas can be compressed on both sides of the piston (3) Multi-cylinder single-acting compressor: one side of the piston is used for compression (4) Multi-cylinder double-acting compressors: compressors with multiple cylinders use both sides of the piston for compression. ♦According to the final exhaust pressure of the compressor: (1) Low pressure air compressor: the final exhaust pressure is 3~10 gauge pressure (2) Medium pressure compressor: the final exhaust pressure is 10~100 gauge pressure (3) High-pressure air compressor: the final exhaust pressure is 100~1000 gauge pressure (4) Ultra-high pressure air compressor: the exhaust end is above 1000 gauge pressure ♦According to the size of the compressor displacement: (1) Micro compressor: below 1m³/min (2) Small compressor: below 1~10m³/min (3) Medium-sized compressor: below 10m³~100m³/min (4) Large compressor: 100m³ ♦According to the speed: (1) Low-speed compressor: below 2000 rpm (2) Compressor with intermediate speed: at 200~450 rpm (3) High-speed compressor: 450~1000 rpm ♦ According to the type of transmission: (1) Electric compressors: those powered by electric motors (2) Pneumatic compressors: those powered by steam engines (3) Compressors powered by internal combustion engines (4) Compressor powered by steam turbine ♦According to the cooling method: (1) Water-cooled compressor: use the circulating flow of cooling water to conduct away the heat given in the compression process (2) Air-cooled compressor: use its own wind power to conduct heat during the compression process through the heat sink ♦According to the transmission method: (1) Install the rigid body coupling to directly drive the compressor or close to the compressor (2) Direct drive compressor with flexible coupling (3) Reduction gear drive compressor (4) Belt (flat belt or V-belt) drive compressor (5) Free piston compressor without crankshaft-connecting rod mechanism (6) Compressor with positive structure – the motor cylinder of the motor compressor and the compressor seat are integrally made, and the compressor uses a common crankshaft Whether air mixed with lubricating oil, air compressor can be divided into oil-type and oil-free type. Lubricating oil has the function of lubricating and cooling any mechanical equipment. It also has an air-tight effect to improve the volumetric efficiency. The effiency is definitely higher than oil-free. It is undeniable that the oil and gas will cause a lot of troubles in use. Even if it is processed by precision filters, it cannot achieve a safe and oil-free state. Although the energy efficiency of an oil-air compressor is higher, the cost of the precision filter are also considerable.

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 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 thickr and sink. singel-way valve controls air flow. Generally 3-4 turns are appropriate. The pre-blowing pressure should be 0.8-1MPa. Bottle bottom and center point has the greatest impact on the quality of the bottle. Improper adjustment often causes fatal defects such as bottle burst (under normal experimental conditions) and leakage. stretching rod The stretching rod must move vertically and steadily during the blowing process. Driving pressure 0.55-0.8MPa. Gap with the bottom mold 2.3-2.5mm. If the gap is too large, the center point will shift; if the gap is too small, the center point will become thinner. High-pressure blow The high-pressure blowing pressure is generally 3.7-4MPa. There are two positions,high pressure gas and exhaust. The length of this time has a great influence on the stability of the bottle volume. Insufficient high-pressure air may cause improper bottle molding and insufficient bottom blowing. Bottle mould During the production process, keep the mold constant temperature, clean, and unblocked vent. When the mold heating and cooling system fails, the bottle neck will be tilted. The volume and height will change, and the bottom will become heavier. Maintaining the mold constant temperature can also prevent condensation on the mold surface. After PET molding, the shrinkage rate is relatively large, generally 1.8%, and it is slightly reduced after adding glass fiber reinforcement, but it still reaches 0.2%-1.0%. Under normal circumstances, high mold temperature shrinkage rate is large, low mold temperature shrinkage rate is small, in order to maintain the stability of PET bottle volume, mold temperature must be strictly controlled. Generally, the temperature of the bottle body is slightly higher, which is 20-45℃, and the bottom requirement is lower, which is 6-15℃. High bottom temperature will make the bottom heavier and the center point thicker. Experts of automatic blow molding machine concluded that there are nozzles in actual production that will affect the forming of PET bottles.

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!

General, there are two type of PET Bottle Blow Moulding Machine, single stage bottle blowing machine and two stage bottle blowing machine.

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. The mounting support plate holds the filling frame and points to the positioning sleeve on the top filling head. The positioning sleeve should be able to move up and down flexibly, and the filling needle is exposed or retracted without hindrance. 5. The switch under the liquid storage tank is turned to the open position, so that the material can flow into the total metering pump. According to the total filling amount of each container, adjust the screw on the crank and rotate the knob of the filling speed control board to 20 degrees. Left and right, then turn the switch on the filling speed control board to the open position. 6. When the filling head out of the liquid is the set amount, screw the liquid amount fine-tuning nut, cover the filling head housing, and loosen the filling bracket support plate.

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 slowly to prevent the gas source from flowing too fast. The dirt can be blown into the solenoid valve and the exhaust valve can be opened for 30 seconds to ensure the air is clean. 12. When starting the machine, it must be convinced that the mechanical part is good and that no one inside the machine has any foreign objects. Especially shake the position to avoid hurting people. At the same time, close the security door. 13. When starting the machine, the motor must be started and the heating machine must be delayed for 30 seconds to prevent voltage fluctuations. Before starting warming, make sure that the cooling water is not turned on. 14. After warming start (2-3) minutes, wait until the oven temperature rises evenly and press the embryo button. At the same time, the bottle blowing power must also be turned on, otherwise it will not blow the bottle. 15. When the machine is in operation, it must pay close attention to whether the machine has abnormal noise. 16. In the event of an emergency, the emergency stop button may be pressed for emergency braking. Then analyze the cause of the formation according to the site conditions and find a quick solution to the problem. 17. After normal operation of the machine, do not put any part of the body into the machine to avoid injury to the robot. If the machine has abnormal noise, it can be observed after deceleration. 18. After the machine is normally produced, the operator must observe the quality of the bottle from time to time in order to avoid fluctuations in the voltage or other factors affecting the blowing quality. 19. When the blowing machine is repaired, press the touch screen fault repair button to ensure safe maintenance. If you need to manually observe the action of each individual cavity, please pay attention to the position of the robot. At the same time, be sure to clear the role of individual buttons, and then move. Make sure that malfunctions cause unnecessary trouble. 20. After each maintenance of the machine, it is necessary to clean things such as tools and screws so as not to remain in the machine and affect the normal operation of the machine.
