Operation Method

1. Setup and Connection: Place the machine on a flat, stable work surface and adjust the four leveling feet to ensure stability. Connect the machine to a properly grounded 220V/60Hz power source. Connect the air compressor to the air inlet using a hose capable of providing at least 0.6MPa working pressure. Verify all connections are secure before proceeding. 2. Install the Mold: Open the protective door and install your mold onto the mounting platform. Use the adjustable clamping brackets to secure the mold firmly in place, ensuring proper alignment with the injection nozzle. Close and latch the protective door before starting the heating process. 3. Set Temperature and Preheat: Turn on the main power switch. Use the digital temperature controller to set the appropriate heating temperature for your material. Press the Heat button to begin preheating. Allow sufficient time for the heating chamber to reach the set temperature and stabilize. 4. Load Material and Inject: Once the temperature has stabilized, pour the plastic pellets into the stainless steel hopper. Set the desired injection time using the timer controller. Press the Start button to initiate the injection cycle. The pneumatic system will drive the piston to inject molten material into the mold cavity. 5. Cool and Eject: Allow the molded part to cool and solidify within the mold according to the material requirements. Open the protective door, carefully remove the finished part from the mold, and inspect for quality. Close the door and repeat the process for additional parts as needed. 6. Power Off: After completing all injection batches, press the Reset button and turn off the Power switch. Allow the heating chamber to cool down before performing any cleaning or maintenance procedures.

Safety Precautions WARNING: Read all safety instructions before use. High temperature surfaces and moving parts can cause serious injury.

1. High Temperature Hazard: The heating chamber and nozzle can reach 350°C (662°F) during operation. Never touch the heating surface, nozzle, or interior components while the unit is on or immediately after power-off. Allow sufficient cooling time before accessing these areas.
2. Proper Grounding: Always connect the machine to a properly grounded AC 220V outlet. The ground terminal must be connected at all times. Never use adapters or extension cords that defeat the grounding pin.
3. Pneumatic Pressure: Ensure the air supply is properly regulated to 0.6MPa maximum. Never exceed the rated pressure. Disconnect air supply before performing maintenance on pneumatic components.
4. Protective Door: Never operate the machine with the protective door open. The door interlock is a safety feature, not an inconvenience. Always secure the door latch before starting an injection cycle.
5. Moving Parts: Keep hands, loose clothing, and long hair away from the injection piston and all moving parts during operation. Wait for all motion to stop before opening the door.
6. Ventilation: Ensure adequate ventilation in the work area, as heating plastic materials may release fumes. Use exhaust systems when processing materials that produce strong odors or vapors.
7. Work Surface: Place the machine only on a flat, stable, heat-resistant surface rated to support at least 150kg. Keep the area around the unit clear of combustible materials.
8. Qualified Personnel: This equipment should be operated only by trained personnel familiar with injection molding procedures and safety protocols. Keep unauthorized persons away from the equipment during operation.
9. Maintenance: Disconnect power and air supply and allow the machine to cool completely before performing any maintenance, cleaning, or component replacement.
10. Material Handling: Use appropriate personal protective equipment including heat-resistant gloves and safety glasses when handling hot materials or molds. Never leave the machine heating unattended.
