An HDPE blow moulding machine can help you shape and create plastic objects with utmost precision. This machine uses high-density polyethylene (HDPE), which is a high-grade plastic, to manufacture high-quality products.
The high efficiency, versatility, and ability to produce accurate products as per the demands of the manufacturers are what make it the most preferred machine in the plastic industry. However, just like any machine, this plastic product-making machine also needs to be used in the right way if you want efficient operations. Worry not, as this post we help you make the most of the HDPE blow moulding machine.
Maintain the Consistent Resin Quality:
The machine can be counted as efficient only when it produces high-quality output. However, to ensure the efficiency of the operations, it is vital to use the HDPE product of the right kind. It varies in molecular weight and flow rate index. If you are constantly using low-grade HDPE, it can lead to poor quality products, like poor wall distribution, blowouts, and incomplete formation. So, here is what you can do:
- Use fresh and raw resins that are clean and well-blended, and it will mould in a better way.
- Deal with the suppliers who promise a high-quality and consistent range of thermoplastic material.
- Before using the plastic, it is essential to check the moisture content. If the water content is too much, it can lead to the creation of bubbles, which will interfere with the precision of the end product.
Fine-Tune Parison Control:
If the control during the operations is not perfect, it will lead to the formation of uneven walls and also increase the scrap rates in the plastic product. So, the parison, which is a hollow tube that shapes the plastic product, should be clean and contamination-free. So, better use these tips:
- Use the advanced parison adjustment features so that the machine can adjust according to the different product needs.
- Inspect the die gap after every use to ensure that it is not worn out or clogged.
- Try to integrate the automated thickness control system, if the machine allows. It will improve the efficiency of the operations.
Optimize the Tempature Zones:
Temperature control is vital during the operations. If there is even a minor increase or decrease in the temperature, it will ruin the quality of the product. The bonding of the material will be weak. So, these tips will help you optimize the operations:
- Once the operation starts, monitor the temperature of the barrel in order to ensure proper gradient.
- Calibrate the sensors and thermocouples regularly in order to register the proper readings.
- The temperature of the die inside the parison should also be accurate. It will otherwise lead to deterioration in the shape of the products.
Regularly Service the System:
The blow moulding process depends heavily on the hydraulic or pneumatic systems for clamping, ejection, and blowing, among other operations. Leaks or sluggish performance can slow the cycles and also reduce the clamping force. It will impact the efficiency of the operations. Here is what you can do:
- Inspect and replace the worn-out seals immediately.
- Monitor and maintain the pressure levels.
- Clean the filters after use and always change the oil as per the manufacturer’s recommendations.
Ensure Proper Mould Maintenance:
If there is any contamination, wear, or damage, it will deteriorate or simply damage the product.
- Clean the mould regularly after use.
- Inspect wear & corrosion in the parting lines and cavities.
- Always use the high-grade mould removal agents. It will be efficiently reduced after the usage.
If these steps are not followed, it will impact the quality of the product.
Adjust the Heat & Air Settings:
Many of the operators may not know this, but the precise air pressure and cooling time also impact the finishing and dimensions of the product.
- Match the blow pressure to the mould size and wall thickness of the product.
- Use the high-speed valves, which will precisely control the air flow.
Monitor & Optimize Cycle:
Cycle time is the key factor when it comes to precisely shaping the plastic products. The optimized cycle reduces the energy consumption and also increases the efficiency of the output. These tips will help you boost the cycle of operations:
- Break the operation cycle into steps: extrusion, blowing, cooling, and ejection. When each step is divided, it will help you pinpoint the delays.
- Use the programmable logic controllers (PLC) to monitor the timing of operations with features like real-time monitoring.
Final Words….
The HDPE blow moulding machine is one of the most reliable equipment when it comes to creating high-quality plastic products. All you need to do is make small improvements in the given area as per the tips mentioned above.
