whole process and equipment of auto blow molding machine
  • 1. Preforms unscrambler will automatic load the preform.
  • 2. Machinery gear will transfers the preform to the heating oven
  • 3. 10psc infrared lamps can be adjusted individually to control the temperature of oven. Preform automatically rotate can make sure preform heating evenly. The infrared thermometer inspecting temperature and will automatic adjust it by itself. All parameter can saw in the touch screen of the Neptune automatic blow molding machine and can easy setting. So that can always fit the best heating temperature
  • 4. The temperature sensor can inspectst the temperature of the preforms. According compare with preset data, it will automatic feedback data to oven, and Oven will automatic adjust the temperature to the necessary temperature.
  • 5. Preforms star-wheel will automatic transfer the after heated preform to the blow mold.
  • 6. First, the preform will stretched in the mold. And then will blow into shape plastic bottle by high pressure air.
  • 7. Machinery gear will transfers the plastic bottle to the air conveyor belt.
  • 8. Air conveyor belt will directly send plastic bottle to washing filling capping machine.

Is the machine fully automatic or semi-automatic?

The machine is fully automatic. It operates seamlessly with high automation, reducing the need for manual intervention. In a fully automatic bottle making machine, the entire production process, including material feeding, heating, molding, and bottle ejection, is carried out automatically. This level of automation enhances efficiency, reduces labor requirements, and ensures consistent and reliable production. The machine is equipped with advanced control systems, allowing it to perform multiple tasks without the need for constant manual supervision.

What is the energy consumption of the bottle making machine?

The bottle making machine has a main machine with a rated power of 49 kW, but in actual operation, it uses around 10 kW. Additionally, the high-pressure (HP) air compressor consumes 25 kW, and the low-pressure (LP) compressor consumes 15 kW. It’s essential to consider both the main machine’s power consumption and the power requirements of auxiliary components, such as air compressors, to assess the overall energy consumption of the bottle making process.

Chief Engineer Is Major shareholders, high quality machine with cheap price

It’s interesting to note that the Chief Engineer is a major shareholder in the company, which may indicate a strong commitment to quality and expertise in the field. Additionally, the combination of high-quality machines and competitive pricing suggests a focus on providing value to customers. Having a key figure like the Chief Engineer as a major shareholder could imply a hands-on approach to ensuring the excellence of the machines manufactured by the company.

The reasons why most bottled water companies produce their plastic water bottles in-house include:

  1. Optimizing Empty Space: Manufacturing the bottles on-site helps utilize empty spaces efficiently, reducing storage costs and maximizing available room.
  2. Preventing Bottle Damage: Empty bottles, especially without contents, can be prone to crushing if stacked. By producing them close to the bottling site, companies can minimize the risk of damage during transportation.
  3. Preventing Pollution: Extended exposure of empty plastic bottles to the air may lead to pollution. Manufacturing bottles on-site reduces the time they spend in an exposed state.
  4. Ensuring Sterility: The plastic bottle-making process involves heating preforms to high temperatures, ensuring the final product is sterile. This quick transition from production to bottling helps maintain a hygienic environment.
  5. Brand Protection: Famous bottled water companies often have unique and distinct bottle designs. In-house production safeguards the integrity of their brand by maintaining control over the manufacturing process.
  6. Cost Efficiency in the Long Run: While there may be initial setup costs, producing bottles in-house can be cost-effective over time. It provides greater control over production processes and minimizes dependency on external suppliers, potentially resulting in cost savings.
