Overview

Automatic dehumidification injection molding machine is a special type of injection molding machine that does not require drying or oven drying of raw materials, but directly adds raw materials into the injection molding process. Eliminating the need for auxiliary machines for drying and dehumidifying raw materials also means eliminating the energy consumption required for drying raw materials and the purchase cost of auxiliary equipment.

Product Details

　　Automatic dehumidification injection molding machineFeatures:

1. Even for large machines, due to their low body, there is no height limit for the factory where they are installed.

2. In situations where the product can be automatically dropped, automatic molding can be achieved without the need for a robotic arm.

3. Due to its low body, it is easy to feed and maintain.

4. The mold needs to be installed by a crane.

5. Multiple units arranged in parallel make it easy for molded products to be collected and packaged by conveyor belts

　　Automatic dehumidification injection molding machineOperation requirements:

1. Before starting production with machine heating, open the cooling water valve and observe whether the water channel is unobstructed.

2. Close the power switch next to the control box, connect the internal power supply, and press the motor start button on the panel to start the oil pump motor.

3. For machines that are used for the first time or have not been used for a long time, after starting the oil pump, they should be run empty for a few minutes before starting the operation.

4. Turn on the heating switch of the material cylinder, connect the electric heating power supply, adjust the constant temperature nozzle and temperature controller on the box door, set the temperature, and observe the current of the ammeter to determine the quality of the electric heating coil.

5. The test run should be carried out sequentially from manual to semi-automatic to fully automatic, and important fastening bolts should be checked for looseness. If any abnormalities are found, they should be stopped immediately. After confirming normal operation or troubleshooting, proceed with the test drive.

6. When the processing stops or the material is changed, the material cylinder should be cleaned. The cleaning work should be carried out while the material cylinder is heated. After the cleaning is completed, immediately turn off the heating switch. Cleaning work is particularly important for processing easily degradable plastics.

Notes:

(1) Check if there is water or oil entering the electrical control box. If the electrical appliance is damp, do not turn it on. Electrical components should be dried by maintenance personnel before turning on the machine.

(2) Check if the power supply voltage meets the requirements, generally not exceeding ± 15%.

(3) Check if the emergency stop switch and front and rear safety door switches are functioning properly. Verify whether the rotation direction of the electric motor and oil pump is consistent.

(4) Check whether each cooling pipeline is unobstructed, and introduce cooling water into the cooling water jacket at the end of the oil cooler and the barrel.

(5) Check whether there is lubricating oil (grease) in each moving part and add sufficient lubricating oil.

(6) Turn on the electric heater and heat up each section of the barrel. When the temperature of each section reaches the required level, keep it warm for a period of time to stabilize the machine temperature. The insulation time varies depending on the requirements of different equipment and plastic materials.

(7) Add enough plastic into the hopper. According to the requirements of different plastics for injection molding, some raw materials need to be dried first.

(8) Cover the heat shield on the barrel to save energy and extend the lifespan of the electric heating coil and current contactor.
