A brief introduction
First and foremost, let’s make a definition.
Water bottle making machine is naturally the theme of carrying liquid, such as our beverages and mineral water. The production method basically uses “hollow blow molding” to form hollow products with the help of gas pressure. This is also a fast-developing production method nowadays. Among them, a mold is used. Compared with injection molding, the price advantage will be particularly prominent.
The equipment is low in price, fast in development, and highly adaptable, and it can also make complex water bottles.
Below we focus on the price of mineral water bottle making machine
A mineral water bottle is composed of two aspects, one is the body and the other is the cap. The machine that makes the bottle body is a blow molding machine, and the one that makes the bottle cap is an injection molding machine. The price of the former ranges from tens of thousands to hundreds of thousands, from domestic to export machines, while the latter requires 60,000 to 100,000 for domestically produced machines. The price gap is so large, so it is necessary to be very careful about the choice of machines. (We will introduce you in detail in the following modules)

And the volume of the mineral water bottle is much smaller than that of the large plastic bottle, but the usage is really large. But we have known that when a mineral water bottle making machine uses the hollow blow molding, the price of machine will not very high, and in the same time, our quality of the water bottle, there will be a very effective guarantee.
In the water bottle blowing machine, there are many options
1. Choose from output and efficiency
The production quality and efficiency of the mineral water bottle making machine are two points that need to be paid attention to. The higher the output, however, does not necessarily mean the better the machine. It is still necessary to pay attention to whether the quality of the products it produces meets the standard. Secondly, pay attention to whether the operation of the machine is stable and consumes electricity during the manufacturing process of the mineral water bottle. The high or low rate, as well as the length of service life, are worth noting and identifying.
2. Choose from the perspective of environmental protection
Customers need to think about whether some of the current machinery and equipment can achieve a high utilization rate of multiple resources. The choice from this perspective will actually have a great impact. If there is a secondary waste, then the customer needs to build it again. Waste treatment on the site, increased financial expenditure, and even the rate of return cannot fill this loophole, and the treatment of water and electricity requires money again. But if this equipment can be environmentally friendly, it can save a lot of trouble.
3. Whether to choose a fully automatic machine
Many factories now choose the operation mode of fully automated machines for making mineral water bottles, because this choice can greatly save manpower, and only a few people can make the equipment run perfectly; and the error rate of fully automatic machines It is also very low and can produce high-quality mineral water bottles.
4. Consider whether the operation is simple
Because you choose simple-to-operate equipment and machines to make mineral water bottles, all the operations of the equipment are started with one-click, and you don’t need to perform various debugging before each startup. The debugging work is already set when the equipment is installed, saving time It also saves money and speeds up product production.
5. Choose from whether there is a protection device
Because the mineral water bottle making machine is equipped with a variety of protective devices, it can avoid the impact of sudden situations on the equipment, reduce damage, and can quickly solve the sudden situation and quickly enter the next production process.
6. Choose from whether there is after-sales service
As for whether a production machine is equipped with good after-sales service, it also represents the integrity of the company’s products. Having a good and perfect after-sales service can also solve many problems and create a good reputation. For this, you can refer to the mineral water bottle maker we sell.
such as one liter water bottle making machine, two liters, five liters, ten liters, fifteen liters and 20 liters. The 1-liter water bottle blowing machine is mainly suitable for small bottles of edible oil, large bottles of water, carbonated beverages, etc. One liter of product can be used up in a short time, so that beverages or edible oils can be kept fresh while keeping the price. Therefore, the demand for 1L plastic bottles is also increasing.
The 20-liter water bottle blowing machine is mainly used for 18.9L bottled water, large-capacity edible oil drums, etc. These items are characterized by being able to be stacked or quickly dispensed, and compared with one liter or five liters, the price advantage is also Will be more obvious.

Working principle and technological process of mineral water bottle making machine
1. Preparation stage
Whether the raw materials for making mineral water bottles are qualified, such as some obvious features observed with the naked eye (whether the color changes, whether the color is uniform), and some tastes are changed, this is a very important step.
2. Warm-up phase
After the preform is irradiated by an infrared high-temperature lamp, it is heated and softened. In order to maintain the shape of the bottle mouth, the bottle mouth does not need to be heated, so a cooling device is also required for proper cooling operation.
3. The forming stage of mineral water bottle
The raw material is continuously squeezed, deformed, and mixed into the preform in the machine. In this process, the thickness of the wall of the mineral water bottle will also be affected, so you must always pay attention to the parameters.
4. Pre-blowing stage
In order to improve the uniformity of the thickness of the wall of the mineral water bottle, and to avoid contact with the inner surface of the parison, a pre-blowing stage is carried out. Therefore, at this stage, it is necessary to pay attention to the pre-blowing time, pressure and other issues.
5. High pressure blowing stage
Use high-pressure inflated parison to reach the final product. At this stage, the parison will be deformed and inflated, but it will also change the surface uniformity and transparency of the parison and the final product, so this step is also important for its comprehensive performance. One of the inspection criteria.
Preparation work
(Refer to blow molding machine)

1. The materials used in extrusion blow molding should meet the required drying requirements, and further drying is required if necessary.
2. According to the product type and size, select the specifications of the machine head, and install the machine head flange, mold body, mold, porous plate, and filter in the following order.
3. Connect the compressed air pipe, install the core mold electric heating rod and the head heating ring.Check and open the water supply system. Adjust the gap of each part of the mold to be uniform, and check whether the center line of the main machine and the auxiliary machine are aligned.
4. Start operating equipment such as extruder, die clamp device, manipulator, etc., perform no-load operation, check whether each safety emergency device is operating normally, and troubleshoot in time.
5. According to the requirements of the process conditions, set the temperature of the extruder head and each heating section, and heat it section by section, and use waste to check the integrity of each heating section to check whether there is heating; wait until the temperature of each part reaches After setting the temperature, the temperature remains constant for 0.5~1h.
6. On the programmable controller, set the wall thickness of each point according to the process regulations.
7. Generally, the outer layer should be opened first to prevent the material from flowing back from the outer layer due to excessive pressure after opening the inner layer. The frequency of the feed flow is gradually increased from small to large to prevent the opening frequency from being too large, causing the screw and the screw to be tightened due to the low temperature.

Merits and Characteristics
Of course, when we mention our mineral water bottle making machine, we still need to mention its features and advantages.
Lower prices and electricity costs, simpler operation and maintenance systems, and while ensuring quality and accuracy, this machine also has faster operating speed and stability. The most important point is that our materials are more Environmental protection, machines will be safer.

How to change the mold
Prerequisite: Stop the machine.
First: Open the safety door and remove the two cooling water pipes on the bottom mold
Use an Allen wrench to loosen the two screws that fasten the bottom mold. When opening the mold, push the mold with your left hand and hold the bottom mold with your right hand. Rotate counterclockwise to lift the bottom mold and place it in the corresponding mold box.
Second: Use your left hand to hold the blowing cylinder and use your right hand to remove the limit pin and put it in a safe position, and replace the corresponding limit pin, and put the newly replaced limit pin back into the mold box
Note: The first step and the second step cannot be changed to prevent the blow nozzle from hitting the bottom mold
Third: Install the bottom mold again. Note: number, capacity, direction. Disassemble the left and right molds. The pressure plate of the left mold must be completely removed before the left mold can be unloaded, and the pressure plate of the right mold is loosened and opened to the right to remove the right mold. Then replace it according to the corresponding number.
Fourth: Replace the bottom mold. Check whether the number corresponds to the bottom mold, and then unplug the air pipe after confirming whether the bottom mold is placed, and then connect the water pipe to close the mold.
Fifth: double check

1. 1.Confirm that the limit pin is correct
2. 2.Confirm that the bottom mold and the water pipe are installed correctly
3. 3.Open the mold to confirm whether the screws are tightened, and the left and right mold numbers are correct
