What Is Pet Blow Molding Machine
A pet blow molding machine is a specialized piece of equipment used in the manufacturing process to produce plastic products.The machine consists of several components, including a hopper, extruder, mold clamping unit, and air injection system, which work together to transform the plastic into the desired product. The process is highly efficient and allows for the mass production of consistent, high-quality plastic items. "PET" stands for Polyethylene Terephthalate, a common plastic material known for its strength, durability, and recyclability. The blow molding machine works by inflating molten PET into a hollow mold to create bottles, containers, and other hollow shapes.
High productivity
It allows several molds working at same time, so as to make more bottles in a certain time.
Consistency
The bottles made by PET blow molding machines are uniform in shape and features.
Versatile
By changing the molds, one machine can make PET bottles in different shapes and sizes.
Reliable
Machine is durable and with proper maintenance, it can be used for tens years.
The first step is to warm up. The embryo body part of the PET bottle preform is heated to a suitable molding temperature, and the inner and outer walls of the embryo body are kept uniformly heated. Because the mouth of the bottle is shaped, no heating is required. Therefore, the bottle finish needs to be cooled during the heating of the embryo body. The second step is blow molding. The uniformly heated preform is sent to the blowing mold through a chain, and is blown into the preform through the middle of the mandrel with sterile high-pressure air for circumferential stretching, so that it is inflated to close to the mold wall, and then cooled.
The third step is demoulding. After blowing the bottle, the machine starts to vent and demould. The fourth step is to send. The formed PET bottles are sent to the lowering station by the conveyor belt, and are pulled up and blown out by the lowering cylinder. If it is in Tech-Long' s blowing, sticking, filling and rotating machine, it will be sent to the next machine to continue packaging.
Things That Are Needed to Actually Make the Pet Blow Molding Machine
The fabricated parts
The Fabricated Parts such as the complete raw body of the machine (which primarily includes the PipeFrame, The machine Oven, The stretch Rod, which stretches and elongates the preform to take the inner height of the mold, which gives the PET Bottle the actual height, The Distributor, which is the heart of the machine, it is on the distributor that all the valves of the machine are fitted and air flow is routed for all the valves from here). The creation of the Fabricated Parts can be outsourced to be made by any fabricator, thus saving your time and efforts.
The actuators
The Actuators (Valves, Cylinders, Sensors, FRL, Regulators) there may be various suppliers of pneumatic valves, Cylinders and Sensors, which mainly work as the actuators for each and every function in the machine and perform the primary task to regulate a proper air flow in the machine. There are separate valves for each and every function to be carried out in the machine. For Eg.: For Blowing function there is a High Pressure, Low Pressure, and an Exhaust Valve. This also can be replaced by the new technology of Dual - Valve, which performs all the three functions. There is a stretching valve, which carries out the preform stretching function, Mould Close/Open Valve, which perform the function of closing and opening of the valve. The Cylinders come in 2 Variants - the hydropneumatic and pneumatic cylinders. The HydroPneumatic Cylinders are mainly used for Mould open and closing function for the proper movement of parts within the machine. While Choosing a Cylinder 2 things must be kept in mind - The Bore and Stroke of the Cylinder, where the Bore is where the piston and seal of the cylinder move. Stroke is the limit upto which the movement of the respective part takes place. It' s basically a device located at the starting point of the machine, from where the Air Flow Supply is started, which is a multi-function device used in order to filter the air from dust particles and circulate in the entire machine. In order to control the amount of air supply, we need a regulator, so that an optimum amount of air is supplied to each valve, for their respective functions. There is analog gauge attached to it which allows us to see what amount of air is being supplied.
Setting up the oven
The Oven of the PET Blowing Machine is the most crucial part of the machine making process. It mainly needs the setup of IR heaters, preform holders, PLC, and Push Buttons for the machine to operate. The function of the heaters or Short-wave IR (Infra Red) Heaters is to heat up the oven which are being placed on preform holders, which take a circular movement around the heaters, and the preforms also rotates around it' s own axis, so that the preforms are heated properly to soften the preforms, in order to easily blow the preforms and produce the PET Bottle. The PLC is where the complete control of your PET Bottle Blowing Machine lies. You can control the amount of heating supplied by the heaters to the preforms, the speed of the preform rotation and revolution around the heaters (usually called as the cycle time) etc. The Push Button are 2 Control Buttons which enable the machine mold to close when the preform is being placed in the mold for blowing purpose. These are containers to hold the preform and their movement is controlled by a chain (usually measure in links. For Eg.: 64 Link Chain is needed in a machine). The Gear Box and DC Motor OR PMDC Motor is needed in order to make the circular movement of the chain which holds the preforms.
The wiring and piping within the machine
There is Panel whose fabrication work can be outsourced from any company involved in doing fabrication work, and after the panel is ready, your main job begins-The Wiring: You need to do complete wiring of the machine to the PLC, heater track (or SSR) in order to control the number of heating zones in the machine, and also from the valves in the machine to the PLC. It's always a good practice to do the work of wiring in a clean and tidy manner, by proper numbering of each and every wire, pertaining to each and every function of the machine whose electrical supply is controlled by it. Wiring is a simple task, once brought in practice, what you just need to do be careful is that after wiring, please check that the machine is getting a proper Neutral and Phase, by using a tester. PU Pipes are being used in order to do the piping within the machine for proper air flow within the machine. Basically Pipes are a medium for the air to flow and travel within the machine. The Piping work is done within the machine from Valves to Cylinders, and then to the Distributor.
Possible Options for Pet Blow Molding Machine
A system for easy retooling of the pet blowing machine, which allows to use many preform neck sizes. Once you change the mandrels, infeed starwheels and grippers, you can start producing pet bottles with a different neck diameter just within 30 minutes. It is particularly suitable for manufacturers of empty pet bottles, as one isn' t limited by one container neck type. System is comprised of two parts – adapting the machine for working with other threads and the extra format parts for retooling the blowmolder.
This feature was developed in order to produce pet bottles which are asymetric, oval or flat. More complicated shapes require different treatment and precise temperature control. Dring the blowmoulding process the preforms are fed through a heating oven. Interchangeably rotating faster and slower, preforms are treated with infrared radiation on a limited surface. With preferential heating system, your blowmoulder will produce a variety of packages without compromising their quality and aesthetics.
A type of technology which allows to manufacture pet bottles with a clearly defined handle. This feature is commonly used for packaging chemical products and edible oil. Our clients usually choose this option for containers of 2-litre volume or bigger. Blowing molds are fitted with a piston, which is pressed into the pet container during the blowing process. As a result, we can precisely achieve the grip effect.
One of the innovations designed for our blow molding machines. Available in achines as default setting, it allows you to recover compressed air during the process of blowmoulding. As a result, you can save 20-50% of air consumption. Blowing system, diagnostic system, heating system and streching system. The recovered resources can be used to power the pet bottle machine or other plant equipment. Sustainability is key in times when energy and supply costs are wavering.
