Car mud groove

Molded Part: Automotive Mudguard 1 Plastic Material: TPE System: 25VE Description: Two-point needle valve gating with cold runner system. Precautions Before Mold Opening: 1. Accurately identify the gate locations through mold flow analysis. 2. Determine the appropriate sizes for runners and gates. 3. Carefully calculate the positions of weld lines and venting points. 4. Ensure balanced control of melt flow at the hot runner outlets. Through mold flow analysis, adjust the sizes of runners and gates: 1. Achieve precise control over the amount of material injected. 2. Prevent excess material from accumulating at the interface between the molded part and the sealing strip. 3. By precisely controlling temperature, injection time, and material volume, ensure that the joint area remains firmly bonded and is less likely to detach.

    Molded part: Automotive mudguard 1

    Plastic: TPE

    System: 25VE

    Note: The 2-point needle valve directs cold runner injection.

    Precautions before mold opening:

    1. Accurately pinpoint the location in mold flow analysis.

    2. Size of the flow channel and sprue

    3. Properly plan the weld lines and venting locations.

    4. Balanced control of hot runner glue output

    Adjust the size of the runners and gates through mold flow analysis.

    1. Achieve precise control over the amount of adhesive dispensed.

    2. Ensures that the adhesive and sealing strip bond together without excess material.

    3. Precise control of temperature, time, and adhesive amount ensures that the joint is less likely to come loose.
