Product Description

The Reason And Countermeasure Analysis Of Product Fuse Connection

1. Welding line

    Weld line, also known as weld mark and water clip, is a thin line produced by cooling the front section of the molten resin in the original H different, and failing to fully fuse in combination. Strictly speaking, almost all products have fuse wiring, it is difficult to completely eliminate, just try to weaken, or move it to a place where it does not matter


  Cause Cuntermeasure
Forming condition

1. The material temperature is too low

2. Mold temperature is too low

3. Injection molding speed is too low

4. Insufficient injection pressure and retaining pressure

5. Insufficient drying of materials, too much gas

1. Increase the molding temperature

2. Set the right temperature

3. Increase the speed, but pay attention to poor exhaust

4. Increase stress

5. Powder and dry materials


1. Screw back pressure is insufficient

2. Improper gate location and number

3. Mold exhaust is poor


1. Increase back pressure

2. Change the location and number

3. Improve the exhaust, reduce the clamping force is conducive to exhaust

Product Design

1. The wall thickness is too thin or the wall thickness difference is too large

2. There are too many holes

3. Improper product color designation, metal color boundary to produce fuse line

1. Avoid it during design

2. Try to reduce the number

3. Change the color or choose the right material


1. The influence of material additives

2. Poor material fluidity

1. Reduce or change additives

2. Improve material mobility


1. The influence of release agent

2. The screw check ring is damaged

1. Try not to use it

2. Replace the check ring
