VIII. Material and smoke issues:
Heating polymers and their additives to the recommended processing temperature range may produce toxic fumes. Evaluating the smoke generated by a given polymer/additive mixture requires information from all relevant material suppliers.
The provision of personal protective equipment and the local and general ventilation required to minimize harmful smoke concentrations should be evaluated.
In the machine, there is an exhaust fan above the heating furnace that can be connected to a 6-inch ventilation duct to expel hot air and harmful smoke.
IX. Fire extinguisher:
Mechanical equipment should be installed near fire-fighting equipment to prevent fires
Firefighting equipment should use carbon dioxide pressurized powder type.

(9) After installing the machine, calibrate it with an air level.
(10) The machine should be connected to the ground.
(11) During the installation of the mold, careful attention should be paid to the opening/closing operation and the condition of the surrounding environment.
(1) The cooling water circulates through the water channel of the heating furnace, with a preset temperature of 30 ℃ and a working pressure range of 2~4kgf/cm2.
(2) Anti corrosion and softening agents should be added to the cooling water to prevent pipeline damage, which can lead to machine damage and worker injury.
(3) The inlet or outlet of the pipeline should be of appropriate size to avoid low pressure. The inner diameter of the pipeline should be greater than 16mm.
- Installation of cooling water:
1 Cooling water is used to cool the mold, with a preset temperature of 10C-12C and a working pressure range of 2-4 kgf/cm2.
2 Antifreeze, preservatives, and softeners, etc. It should be added to frozen water to avoid damage to the pipeline.
3 The diameter of the import or export pipeline should be greater than 16mm to reduce pipeline losses.
4 In order to maintain a stable water temperature, all pipelines must undergo heat insulation treatment to prevent condensation.
Note: The mold water circuit cleaning intake valve is only used for cleaning the water circuit or mold replacement, and for emptying the water circuit
Residual moisture, in addition, please do not open the inlet valve to prevent frozen water from re entering the air compressor system, causing rusting of the air compressor system pipes, impurities, abnormal operation of the cylinder and solenoid valve, and damage.
4 Installation of operating pressure:
(1) The working pressure is 7kgf/cm2, so the pressure source should be 7.5-8kg/cm2 to avoid insufficient pressure.
2 The pipeline should have an inner diameter greater than 18mm and use pressure resistant pipes greater than 10 kgf/cm2.
3 The operating pressure isolator is an air inlet control valve that can be locked.
5 Installation of blowing pressure:
(1) The maximum blowing pressure is 35 kgf/cm2, so the safety of the pipeline system should be checked to avoid any accidents.
(2) Pipelines with an inner diameter of over 18mm should be used to avoid low pressure and maintain stable quality.
(3) ISO/DIS 8573-1 Level 1, compressed air with oil carrying capacity less than 0.01mg/m3 and dust carrying capacity less than 0.1mg/m3 shall be qualified.

(2) The sliding part of the grease nipple on the machine should be lubricated in the direction of the arrow
IV. Operation and adjustment:
After setting up, functional testing should be conducted jointly by one person and another.
1 Pre startup inspection:
- Photoelectric sensors on the feeding track:
There are two sets of photoelectric sensors in the middle and end of the photoelectric track. The upper photoelectric switch is used to control the feeding time on the conveyor. When the photoelectric sensor measures the pre feed, after a certain time delay, the feed will begin. The lower photoelectric sensor is used to measure the feeding time of the billet on the feeding track. When the photoelectric sensor does not respond to the preform, the conveyor stops and the robotic arm stops grabbing the preform, while the spindle continues to operate.
We need to confirm whether these two sets of photoelectric sensors can respond. Fill the feeding track with the preform and observe if the light of the photoelectric sensor is on. If the light is on, it indicates a normal situation. However, if the light still goes out, it means no reaction has occurred. Loosen the fixing bolts on the sensor, move the position and angle of the sensor until it can respond. Otherwise, the machine will not function properly.
2 Pre molding photoelectric sensor:
Before entering the mold after heating the prefabricated parts, there is a set of photoelectric sensors that cannot work without responding to the mold, stretching rod, and high-pressure air. When confirming, a preform needs to be placed on the main axis between the photoelectric sensor groups. Then loosen the fixing bolts on the photoelectric cell. Sensor, adjust the position and angle until the light on the sensor lights up. This means that the prefabricated parts entering the mold normally will complete all performance

It is placed between the feeding and discharging robotic arms to determine if the formed bottles have been correctly removed. Otherwise, the feeding robotic arm will come into contact with the formed bottles.
