Technical Support

Extrusion laminating process common problems and solutions

Extruded composite is a high pressure high temperature rapid processing of plastic process, which links to the machine, a variety of factors raw materials, personnel of each operation. The actual process will be a variety of abnormalities, now on a variety of anomalies will be described.

Problems CAUSE Solution
Poor adhesion

1. The resin surface oxidation is not sufficient

2. The resin temperature is too low

3. Composite wheel insufficient pressure

4. incomplete drying primer low printing ink adhesion

5. The substrate is abnormal

6. Check whether the damp substrates

1.1 increase in resin temperature

1.2 reduce line speed

1.3 increase in the air gap distance

2.1 increase in resin temperature

2.2 increase backpressure

2.3 Check the heater

Composite wheel pressure increase

4.1 increasing the drying temperature

4.2 reduce speed

4.3 to adjust the amount of air intake and exhaust

Check the base of factor 5.1

5.2 Check the base with non-polluting

5.3 Have damp printing ink

Replacing Ink

Uneven thickness

1.T-die temperature is set incorrectly

2. Composite wheel uneven pressure

3. foreign matter adhering to die

4. deflector abnormal

Re-adjust the temperature

2.1 composite wheel balance adjustment

2.2 Replacing the composite wheel

Shutdown, cleaning die

4.1 Check the deflector Model

4.2, lower deflector position adjustment

Composite wrinkles

1. Composite wheel roundness bad

2. The speed is too low

3. Import wheel imbalance

The tension is too small

5. Composite wheel of a foreign body

6. The original film is the wrong way to wear paper

Replace or abrasive composites wheel

Increase recombination velocity

Import balance wheel adjustment

Increased tension

Cleaning of wheel

Check wear paper mode

Gel and fish eye pattern

1. The resin temperature is too low

2. Resin damp

To improve resin temperature

Re-drying resin

Crystallization point

1. The resin processing temperature is too high

2. Replace the resin is not sufficient

Lower resin temperature

Replace the resin

Wrinkles shaft

1. The winding tension, weakness set improperly

2. The substrate on both sides of the thick

Reset tension and weakness
2.1, trimming
2.2 Adjust the thickness

Poor transparency

1. The temperature of the cooling wheel
2. The cooling roller surface treatment discomfort, kneading the resin shortage

2.1, increasing backpressure

2.2, adjust the temperature

Shrink film

1. The resin temperature is too high

2. The tension of the tension is too large

3. The composite speed is too low

4. insufficient cooling cooling wheel

Lower resin temperature

Adjust tension

Increase recombination velocity

Lowering the cooling temperature
