    DKM PET Injection Molding Machine in Operation

    With electrical pre plastic charging system, DKM-PET Injection Molding Machine realize fast and precise injection molding.

    Using Guidelines:

    Step 1

    Getting started

    Start by looking over the machine for any obvious flaws or damage. Check the mold and ensure it is clean and properly installed. Make sure the required raw materials, such as PET resin, are available and stored in a suitable condition.

    Step 2

    Power on the PET

    Power on the PET injection molding machine and allow it to warm up according to the manufacturer's instructions. Set the temperature and pressure settings based on the specific requirements of the PET material being used. Adjust the mold clamping force, ejection system, and other machine parameters as necessary.

    Step 3

    Loading material

    Load the PET resin into the hopper of the machine, ensuring that it is free from moisture or contaminants. Adjust the drying and dehumidifying settings if required, to maintain the material's optimal condition.

    Step 4

    Setting the requirements

    Set the injection speed, pressure, and time according to the desired specifications for the plastic part. Activate the injection unit and monitor the machine closely during the injection phase. Ensure that the molten PET material fills the mold cavity uniformly and accurately.

    Step 5

    Maintaining the temperature

    Allow sufficient time for the injected plastic to cool and solidify within the mold. Maintain the appropriate cooling temperature and time, as specified by the resin manufacturer, to ensure proper part formation and minimize defects.

    Step 6

    Ejecting the parts

    Once the plastic part has cooled and solidified, open the mold using the machine's controls. Activate the ejection system to release the part from the mold. Ensure that the ejection pins or mechanisms do not damage the part during removal.

    Step 7

    Evaluating the quality of parts

    Carefully examine the produced parts for any defects, such as warping, shrinkage, or surface imperfections. Use measuring tools and gauges to verify the dimensions and specifications of the parts. Conduct quality control tests, if required, to ensure the parts meet the desired standards.

    Step 8

    Repeating the process

    If everything is in order, repeat the process for subsequent cycles. Adjust the machine settings, as necessary, to optimize production efficiency and maintain consistent part quality.

    Step 9

    Maintenance of machine

    Regularly clean and maintain the PET plastic injection molding machine to prolong its lifespan and prevent malfunctions. Remove any excess material or residue from the machine and its components. Lubricate moving parts, check for wear and tear, and address any issues promptly.
