Space-saving vertical structure occupies minimal floor space while providing full injection molding functionality. 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.

Transparent Safety Door

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. Secure latch mechanism prevents accidental opening during operation.

Stainless Steel Hopper

Corrosion-resistant stainless steel hopper holds up to 40g of material and features a funnel-shaped design for smooth, consistent material flow. Polished mirror-finish surface prevents material adhesion and allows for quick cleaning between different material batches.

Precision Mold Mounting System

Robust mold mounting platform accommodates molds up to 200×200×210mm and features adjustable clamping brackets for secure mold fixation. Precision-machined flat surface ensures accurate mold alignment, resulting in consistent part quality and reduced defects.

Pneumatic Drive System

Powered by a reliable pneumatic cylinder operating at 0.6MPa air pressure, delivering smooth and consistent 1-ton injection force. Integrated air filter-regulator-lubricator unit with clear pressure gauge ensures clean, stable air supply while protecting pneumatic components from contamination.

Precision Injection Nozzle

Specially designed injection nozzle features precision-machined components that ensure accurate material delivery and prevent leakage or drooling between shots. 20mm diameter piston with 150mm stroke provides optimal injection performance for small parts manufacturing.

Intelligent Digital Control Panel

Intuitive front control panel with separate digital displays for timer and dual-zone temperature controller providing real-time process monitoring. Temperature range from room temperature to 350°C covers virtually all common thermoplastic materials.

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. Threaded adjustment mechanism allows precise leveling on uneven floors, ensuring accurate mold alignment.

Quality Internal Components

Internal electrical and pneumatic systems utilize industrial-grade solenoid valves, relays, and wiring to ensure long-term reliability and easy maintenance. Organized layout simplifies troubleshooting and reduces downtime for servicing or repairs.

[Wide Material Compatibility] Processes PP, PC, ABS, PET, PVC and other thermoplastics with temperature range RT-350°C for maximum versatility.

[Comprehensive Safety Protection] Transparent protective door with secure latch, prominent warning labels, and door interlock prevent operation when open.

[Energy-Efficient Operation] 1000W power consumption with efficient pneumatic drive and digital temperature control maintains precise heating with minimal temperature fluctuation.

[User-Friendly Interface] Intuitive front panel with separate digital displays for timer and temperature, clearly labeled controls require minimal training.

[Durable Construction] Heavy-duty steel frame, stainless steel hopper, precision-machined injection components, and industrial-grade pneumatics ensure years of reliable service.

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.

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. Always follow safety guidelines.

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.

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.

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.

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.

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.

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.

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.

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.

Maintenance: Disconnect power and air supply and allow the machine to cool completely before performing any maintenance, cleaning, or component replacement.

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.
