⚠ 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.

ITEM DETAILSCompact Vertical Design

The space-saving vertical structure occupies minimal floor space while providing full injection molding functionality. The upright design allows gravity-assisted material feeding and easy access to the mold cavity. Four heavy-duty adjustable leveling feet with rubber pads provide exceptional stability during operation while minimizing vibration transmission to the work surface, ensuring accurate mold alignment and consistent part quality even on uneven floors.

Transparent Safety Door

The protective door features a large transparent viewing window made of high-temperature resistant material, allowing operators to safely monitor the entire injection process without exposure to hot surfaces or moving parts. The secure latch mechanism prevents accidental opening during operation, and the robust hinges ensure smooth door movement throughout the machine\'s service life. The dark gray door panel complements the white body for a professional, clean appearance.

Stainless Steel Hopper

The corrosion-resistant stainless steel hopper holds up to 40g of material and features a funnel-shaped design for smooth, consistent material flow into the heating chamber. The polished mirror-finish surface prevents material adhesion and allows for quick cleaning between different material batches. The generous opening diameter makes loading pellets easy while the tapered bottom ensures reliable feeding into the 20x110mm heating zone without bridging or jamming.

Precision Mold Mounting System

The robust mold mounting platform accommodates molds up to 200x200x210mm and features adjustable clamping brackets for secure mold fixation. The precision-machined flat surface ensures accurate mold alignment, resulting in consistent part quality and reduced flash or defects. The T-slot or bolt-hole pattern allows flexible positioning of various mold sizes, while the generous daylight opening provides ample space for mold installation and part removal.

Pneumatic Drive System

Powered by a reliable pneumatic cylinder operating at 0.6mpa air pressure, this machine delivers smooth and consistent 1-ton injection force. The integrated air filter-regulator-lubricator unit with clear pressure gauge ensures clean, stable air supply while protecting pneumatic components from contamination and premature wear. The blue aluminum air connector provides quick, leak-free connection to your shop air supply, and the transparent filter bowl allows visual monitoring of condensate levels.

Precision Injection Nozzle

The specially designed injection nozzle features precision-machined components that ensure accurate material delivery and prevent leakage or drooling between shots. The 20mm diameter piston with 150mm stroke provides optimal injection performance for small parts manufacturing with consistent fill rates. The nozzle tip is designed for proper contact with the mold sprue bushing, ensuring clean material transfer and minimizing waste or contamination between injection cycles.

Intelligent Digital Control Panel

The intuitive front control panel places all essential controls within easy reach. Separate digital displays for timer and dual-zone temperature controller provide real-time process monitoring at a glance. The temperature range from room temperature to 350°C covers virtually all common thermoplastic materials, while the 0-9999s adjustable injection time accommodates various part geometries and cooling requirements. Clearly labeled buttons for power, heat, start, and reset functions make operation straightforward.

Adjustable Anti-Slip Feet

Four heavy-duty adjustable leveling feet with rubber pads provide exceptional stability during operation while minimizing vibration transmission to the work surface. The threaded adjustment mechanism allows precise leveling on uneven floors, ensuring accurate mold alignment and consistent part quality. The metal construction with rubber base prevents sliding during the injection stroke while protecting the floor surface from scratches or damage during machine positioning.

Quality Internal Components

The internal electrical and pneumatic systems utilize industrial-grade solenoid valves, relays, and wiring to ensure long-term reliability and easy maintenance. The organized layout of components within the accessible rear and side panels simplifies troubleshooting and reduces downtime for servicing or repairs. All wiring is properly routed and secured with cable ties, and the terminal blocks are clearly labeled for quick identification during maintenance procedures.

ITEM OPERATING INSTRUCTION

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.
