-
Pinhole claim countermeasures
Small holes in the coating may be caused by the surface of the material or the drying conditions.

-
Rust recurrence complaint measures
Even if there are no visible issues at the time of shipment, I will explain the causes of red rust appearing during storage or after delivery.

-
Measures for paint peeling complaints
Defects in which the paint film peels off during assembly may be caused by the pretreatment rather than the paint itself.

-
Blister prevention and insufficient chemical treatment
Blister defects may be caused by insufficient chemical treatment. I will explain the importance of adhesion and corrosion resistance.

-
The cause of the blister that will appear in a few months.
Blisters that occur months later, even if there are no issues at the time of delivery. This explains the relationship between internal corrosion and pre-treatment.

-
The relationship between blister defects and moisture.
Blistering defects may be caused by moisture or corrosion rather than paint. I will explain the phenomena occurring within the paint film.

-
The blind spot of pinholes and insufficient drying.
Insufficient drying after cleaning may be the cause of pinholes. I will explain the defects caused by residual moisture.
last updated
-
The chain of pinholes and insufficient degreasing.
The degreasing process, which is often overlooked in pinhole prevention measures, will be explained in terms of how residual oil can lead to a decline in quality.

-
The relationship between pinholes and internal gas.
Pinhole defects that are likely to occur in die casting and casting. This explains the relationship between internal gas and pre-treatment.

Aluminum paint peeling and surface roughness
Peeling paint on aluminum products may be caused by surface roughness. I will explain the pretreatment that affects adhesion.
last updated
-
Reoccurrence of paint peeling and abnormalities in the previous process.
The paint peeling that does not improve even after reviewing the baking temperature. I will explain the relationship with the often-overlooked previous processes.

-
Is the paint peeling due to insufficient pre-treatment?
Most paint peeling is caused not by the paint itself but by inadequate pre-treatment. This explains the poor adhesion due to insufficient degreasing and chemical treatment.

-
The aluminum die-cast coating had chipping, which was an unexpected defect.
The cause of chipping is poor adhesion and insufficient film thickness. A film thickness of over 40 microns can reduce the occurrence rate by 95 percent.

-
The uneven gloss of aluminum die-cast painting was a defect that diminished its sense of luxury.
The cause of gloss unevenness is the difference in film thickness and drying speed. By managing the drying time within plus or minus 5 minutes, the improvement rate is 80 percent.

-
The cause of complaints regarding aluminum die-cast painting was contamination by foreign substances.
70 percent of foreign matter contamination is caused by the cleaning process. It is possible to reduce it by 99 percent through filter replacement and cleaning solution management.

-
Aluminum die-cast painting had issues with color unevenness affecting production efficiency.
The cause of color unevenness is the variation in film thickness. Managing it within plus or minus 30 microns can reduce it by 90 percent.
last updated
-
Aluminum die-cast painting was all about managing the viscosity of the drips.
The cause of the dripping is the mismatch between paint viscosity and curing temperature. It explains the phenomenon where a 20-degree difference results in a threefold increase in occurrence rate.

-
Aluminum die-cast coating faced the risk of blistering and paint peeling.
The cause of blisters is the volatilization and gasification of oils. The key to prevention is the simultaneous removal of moisture and oils from the material.
last updated
-
Aluminum die-cast painting was all about pinholes in quality.
The true cause of pinhole formation is not the paint, but insufficient gas release. This explains how it can occur even with heating at 60 degrees.

-
Aluminum die-cast coating peeling was the sole cause of quality degradation.
The cause of paint peeling is poor adhesion. By simultaneously optimizing degreasing and chemical treatment, the occurrence rate can be reduced by 99 percent.

-
The aluminum die-cast coating had chipping, which was an unexpected defect.
The cause of chipping is poor adhesion and insufficient film thickness. A film thickness of over 40 microns can reduce the occurrence rate by 95 percent.

-
The poor curing of aluminum die-cast coatings was a serious durability issue.
Eighty percent of poor hardening is due to insufficient baking temperature. An explanation of the measured value that hardness decreases by 20 percent with a 10-degree difference.
last updated
-
Aluminum die-cast coating was a threat that jeopardized long-term warranty due to rust reoccurrence.
The cause of rust reoccurrence is the thinness of the chemical treatment film. Ensuring a thickness of 8-12 microns allows for 5 years of corrosion resistance.
