What equipment is required for plastic injection molding service?

1. Injection Molding Machine

The injection molding machine melts the plastic resin, injects them into the mold, and ejects them after molding process. 

As injection mold company china, HanKing Mould injection molding machine ranging from 60 ton to 1600 ton, and equipped with all auxiliary equipment that can produce high-quality injection molded products for customers.

The injection molding machine mainly consists of the following parts:

Injection mechanism: composed of components such as hopper, barrel, screw, motor, oil cylinder, nozzle, etc., capable of completing particle conveying, melting, and injection actions.

Heating mechanism: including heating coils, thermocouples, temperature control plates and other components, used for heating granular materials.

Mold closing device: used to open and lock the mold to prevent melting during the injection process from supporting the mold.

Electrical control: including various electrical components, receiving and issuing commands.

Ejection mechanism: Ejects the formed product from the mold.

Drive mechanism: Hydraulic or electric, providing power for the injection molding machine.

2. Injection Mold

The injection mold is installed between the injection molding machine template and the fixed template. The molten material enters the injection molding cavity from the fixed template side.

Molten plastic pellets are formed in molds. The mold is equipped with a cooling water pipe, which takes away the heat. After the product is cooled, the mold opens and the product is ejected.

3. Mold Temperature Controller

The temperature of the mold affects the speed of cooling, with low temperature, fast cooling, reduced cycle time, high temperature, and good surface quality of the product. Different types of materials require different mold temperatures, and a mold temperature controller is used to maintain a stable temperature of the mold.

The mold temperature machine has a water temperature machine and an oil temperature machine. The heat transfer medium of the water temperature machine is water, while the oil temperature machine uses specialized heat transfer oil. The heating range of the two is different, after all, the boiling point of water is only 100 degrees.

4. Water Chiller

Provide cooling water with a lower temperature for the injection mold. There are air-cooled and water-cooled. Air cooled: The coolant heat is taken away by the fan. Water cooled: The heat of the coolant is carried away by the circulating water. The appearance can be distinguished by the presence or absence of a fan on the top of the device.

5. Plastic Dryer

Before entering the injection molding machine for processing, plastic needs to be dried to remove moisture.

The dryer generates hot air at the set temperature, which enters from the lower part of the hopper and dries the material. Different materials have different hot air temperatures and drying times. For example, ABS: drying temperature 80 degrees Celsius, drying time 2-4 hours; PC: Drying temperature 120 degrees Celsius, drying time 6-12 hours, specific parameters refer to the data provided by the material supplier.

6. Robot

Remove the product or runner gate from the injection mold.

It can transform semi-automatic production into fully automatic, with good safety and high efficiency.

7. Mold Monitor

Compare the real-time image with the stored normal image, and if the alarm area exceeds the set value, an alarm will be issued. Used to monitor defective products, prevent molding, and protect molds.

8. Material Mixer

Add the color powder or masterbatch to the plastic pellets and mix well in the mixer.
