Congratulations on choosing a Yushun mechanical PET bottle blowing machine! To ensure optimal performance, long service life, and the highest product quality from day one, it is crucial to follow proper pre-operation procedures. Neglecting these steps can lead to machine damage, production downtime, and defective bottles.
Please review the following essential precautions before starting your machine.
Stable Foundation: Ensure the machine is installed on a solid, level floor capable of supporting its weight and vibration. An unstable foundation can cause misalignment and critical component failure.
Adequate Space: Maintain sufficient clearance around the machine for operation, maintenance, and ventilation. Check that all air vents are unobstructed.
Environmental Control: The blowing area should be clean, dry, and free from excessive dust, humidity, and corrosive chemicals. A controlled environment prevents contamination of preforms and finished bottles.
Voltage and Stability: Confirm that the incoming power supply voltage and frequency match the machine's specifications exactly. We recommend using a voltage stabilizer to protect against power surges and fluctuations.
Proper Grounding: The machine must be properly grounded to prevent electrical shock and protect sensitive electronic components from static damage.
Air Supply Quality: The compressed air must be dry, clean, and oil-free. Verify that your air compressor and filtration system (dryers and filters) are functioning correctly. Contaminated air is a primary cause of mold and valve damage.
Water Cooling System: For water-cooled models, check the flow and pressure of the cooling water. Ensure there are no leaks and that the water temperature is within the recommended range for efficient mold temperature control.
Lubrication Check: Verify that all lubrication points (e.g., guide rails, cams, cylinders) have the correct type and adequate amount of lubricant as specified in the manual. Do not over-lubricate.
Mold Installation: Inspect the neck and blow molds for any damage, cracks, or wear. Ensure they are correctly installed, securely fastened, and properly aligned. Misaligned molds will produce defective bottles and cause premature wear.
Heating System: Visually inspect the heating lamps in the oven. Ensure they are securely in place and that the reflectors are clean. A dirty or misaligned heating system leads to uneven preform heating and poor bottle quality.
Control Panel Settings: Before feeding preforms, power on the machine and review the PLC or touchscreen control panel settings. Check that the heating temperatures, blowing pressure, timing sequences, and other process parameters are set according to the bottle design and material you are using.
No-Load Test Run: Run the machine without preforms ("dry cycle") to observe the movement of all mechanical parts. Listen for unusual noises and watch for smooth, synchronized operation of the clamping, stretching, and blowing stations.
Safety Systems Test: Verify that all emergency stop buttons, safety doors, and guards are functional. Never operate the machine with safety features disabled or bypassed.
Preform Quality: Use high-quality, clean PET preforms that are compatible with your machine. Dirty or degraded preforms can damage the machine and result in burst bottles or contamination.
Warm-Up Time: Allow the machine, especially the heating oven, sufficient time to reach and stabilize at the set operating temperatures. Rushing this process will result in inconsistent bottle quality.
By diligently following these pre-use precautions, you are laying the foundation for efficient, safe, and profitable production. Your Yushun blowing machine is built for reliability, and proper care ensures it will serve your business for years to come.
