Visual inspection standard for electroplated castor parts
Code for visual inspection of electroplated castor parts
Inspection items, inspection requirements and criteria
The color difference surface coating color shall not exceed the signed template

① Under 40W fluorescent lamp or natural light, the visual acuity is more than 1.0, and the object

is placed at 45 ° of the viewing angle of the human body, there is no significant difference

② If there are differences in colors, but the overall color matching is good after combination, and

there is no obvious difference, it is acceptable

③ After combination, the overall color difference is obvious and unacceptable
There shall be no obvious pits or sand particles on the surface of pitted / sand objects

① S 0.5mm, within 10cm *, no more than 3pcs

② S1mm, within 10cm, no more than 2pcs

③ Sand area < 5mm, and its diameter can exceed 0.1mm
There shall be no bubbles on the surface of the blistering coating and the coating shall fall off

① ) s0.5mm, within 10cm *, class a surface shall not have bubbles, class B surface shall not exceed

3pcs, and class C surface shall not exceed 5pcs

② ≤ 1mm within 10cmf, grade B surface shall not exceed 2pcs and grade C surface shall not exceed

3pcs

③ If the blister is inside, it can be covered after assembly, which is acceptable

④ If the blister is too large, it can be covered after assembly, but it is easy to crack and cause the

coating to fall off, which is unacceptable

The plating protective layer on the surface of the object shall not fall off

① The class a surface and class B surface of the object shall be free of coating falling off

② The falling off area of grade C surface coating is 1mm1mmfsxs3mmi

③ If the surface coating falls off and can be covered after assembly without exposing the object matrix,

it is acceptable

④ It can be covered after assembly, but the object matrix has been exposed, which is easy to rust and

unacceptable
After treatment, the surface of the bumped object shall not have obvious bumps ① the bumps on the

class a surface of the object are unacceptable
The anti-corrosion ability of the coating surface tested by salt spray must meet the detection

requirements of the specified time ① the salt spray test fails, and a large area is seriously rusted,

which is not acceptable

② During salt spray detection, there is rust on the edge of the object and the edge of the hole, and

its periphery is not more than 5mm, which is acceptable ③ there is no rust on the front surface of

the object or the outer surface of the lampshade ④ there is no rust on the inner surface of the object,

after detection, the rust is within 10cm, the diameter is ≥ 1mm, not more than 3pcs, and the distance

is ≥ 25cm ⑤ if the outer surface of the electroplating layer of the object begins to rust within the

specified time (at least 18 hours), The samples shall be placed in the iron products in the normal

shipping packaging mode (plastic bag, color box and outer box) for three months, and the changes

shall be observed once a week. If there is rust, the unplated surface is unacceptable, and the

unplated surface is not allowed

① ) the surface of electroplated parts shall not be unplated

② For the unplated traces around the electrode points of caster electroplated parts, their size

can be covered after assembly or their interior can not be seen without folding after assembly

③ The hole electrode point can be covered or not completely covered after assembly, and its

exposed area shall not exceed 2mmi, and it is not obvious when observed at 30cm, which does

not affect the overall appearance requirements

④ Rust is found in the unplated parts inside the electroplated parts, which is unacceptable

⑤ Due to the electrode relationship inside the electroplated parts, the surrounding areas or internal

corners nearby, during the electroplating process, the electroplating layer is thin or yellow due to

excessive discharge. There is slight rust during salt spray test or it can be basically covered after

assembly, which is acceptable

⑥ If the yellowing area exceeds 2 / 3 of its surface or cannot be covered, it is not acceptable
