20g Mini Desktop Vertical Injection Molding Machine Pneumatic Plastic Injector

Pneumatic Plastic Injection Molding MachineManual Mold, 0-15g Capacity, 500WKey Features

• ✅ Maximum Injection Amount (theoretical): 0-15g/time
• ✅ Cost Saving: This injection molding machine uses a simple hand-disassembled mold to complete the injection molding, and the mold can be replaced to achieve multiple uses of one machine.
• ✅ Heating Temperature: 0-300°C (0~572°F). The temperature can be adjusted. PEPP 200-240°C, ABS 180-210°C, PS 180-200°C
• ✅ Pneumatic Plastic Extruder: You need to prepare the air pump. A 30L or higher power air pump is recommended, and the air pressure requirement is between 0.65-0.85Mpa.
• ✅ Application: Soft plastics such as PP, PE, ABS are the most suitable, and PS, PA, PET, TPU, and PVC can also be used. Only a small amount of sample is needed for easy extrusion. Capable of test piece production and small batch production.

Operation InstructionsInjection Pressure Adjustment

The pressure regulator\'s pressure gauge displays the current operating pressure when you lift the black knob and turn it clockwise. Turning it increases the pressure, and turning it counterclockwise decreases the pressure (the pressure does not change immediately after adjustment, but changes with one operation).

Adjust the temperature and pressure appropriately according to the fluidity of the plastic.

Heating Temperature Adjustment

The heating system can be turned on/off by the button switch on the temperature controller. Press the set button on the thermostat to set the temperature, then use the up and down arrows to adjust the temperature to the range required for plastic processing.

PEPP: 200-240
ABS: 180-210
PS: 180-200

Stainless Steel Injection Filling Port

It\'s recommended to fill the plunger barrel to 80% or less each time. If you put in too much material, problems such as sticking between the plunger and barrel, or sticking between the top and bottom will occur.

Theoretical max. injection amount per time: 0-15g

Mold Position Adjustment（The machine does not include vise and molds）

Adjust the height of the mold, and make the distance between the mold gate and the machine nozzle about 5mm. If the distance between the mold gate and the machine nozzle is too high (more than 10mm), it may cause adhesive leakage.

Align the gate and nozzle position, press the foot switch to complete the injection molding, and release the switch.

Wait for the mold to cool before opening the mold.

The factory air pressure adjustment is usually 0.2mp. If the injection molding is poor, adjust the air pressure to the appropriate range. The adjustment space is 0.2mp-0.75mp; the higher the air pressure, the greater the injection pressure.
