2016-02-02 hits: 3789

Packaging quality requirements:

1, to

Clear to incoming packaging, packaging can ensure effective protection products, to avoid damage during transportation and handling process, while ensuring that the incoming product easy identification and traceability.

2, the scope of

Applicable to all metal parts processing, product suppliers to ensure the safely arrived at the designated location.

3, test conditions

Normal illumination or visual (800LUX).

4, the examination content

4.1 packing shall be recorded on the accuracy and integrity of information:

4.1.1 purchase order (if required)

4.1.2 part number (if required)

4.1.3 product name

4.1.4 number (if required)

The number of 4.1.5 per box

4.16 date

4.1.7 QC inspection status

4.2 packing list must be attached to each shipment, should contain the following information

4.2.1 the name of the customer (if required)

4.2.2 order number

4.2.3 total number of cases

4.2.4 purchase order No.

4.2.5 part number

4.3 packaging

4.3.1 all materials must be packed in order to avoid destruction in the process of transportation, including the use of the corresponding backlog Zhen padding, spacer, filler etc.. The packing box must be closed and must be the top of the box bottom box sealing tape.

4.3.2 packaging must have sufficient strength to resist external forces in order to protect the internal packaging. The packing gear shall meet the specifications (to avoid shaking or damage during transportation.

4.3.3 odd cartons must be clearly identified.

4.3.4 packaging packaging box set, the direction is correct, neat and clean, no damage: label complete, correct, and consistent label number.

Quality requirements:

1, to

Clear the incoming quality requirements, to ensure that the electroplating products to meet customer needs.

2, the scope of

Suitable for all metal parts materials (galvanized products), suppliers to ensure product integrity at the designated place.

3, test conditions

Natural light or reflected light scattering light by visual inspection.

4, the examination content

Note the defect inspection method inspection standards / project classification

The appearance of 30cm visual without the following defects: (normal coating uniform and fine crystalline, complete passivation film was shiny color)

1, rough coating

2, coating gloomy

3, foaming coating

4, peeling or serious fringe

5, the passivation film and passivation liquid trace serious osteoporosis

6, no local visual coating

The thickness / weight (mass) calculated by xxg/m2 - V supplier Report

1, after the coating adhesion can bend 180 degrees and bending diameter without any metal loss in any direction

Corrosion resistant 1, salt fog test, on the surface of workpiece distance normal distance visible corrosion

4.3 final processing - coating should undertake the following a final treatment process:

Type description:

I plating, don't need follow-up treatment

II need to transform processing color chromate coating

III need to transform processing colorless chromate coating

IV phosphate conversion coating processing

Anti corrosion requirements

Paint quality inspection:

1, to

Clear the incoming thermosetting powder quality requirements, to ensure that the powder coating products to meet customer needs.

2, the scope of

Applicable to all metal parts processing, product suppliers to ensure the safely arrived at the designated location.

3, test conditions

Natural light or reflected light scattering light by visual inspection.

4, the examination content

Note the defect inspection method inspection standards / project classification

The appearance of a visual defect without following meters:

1, color, pattern, gloss and model is consistent with that of the same batch of products have no color;

2, the coating surface smooth, uniform surface shall have the following defects:

1) not sticky back surface dry, the actual surface (or dry, easy to produce prints), sticky fabric fluff phenomenon;

2) flow: the surface of liquid flowing like protrusions at the top of the circular bead;

3) particles: surface is granular, touch a sense block;

4) orange peel appearance such as orange peel like jagged, irregular waves;

5) surface leakage through the blue color, exposed substrate;

6) on the surface due to shrinkage and showing holes (MA), also known as pinhole;

7) flowers: surface color shades of a shaped pattern;

8).The accumulation of local bumps, wrinkles (like wrinkles except flour);

9) inclusion: coating with debris;

10) mechanical damage caused by external forces: scratch, scratch, abrasion and collision. visual

The pencil hardness of H

The adhesion of 0~1

Gasoline resistance reached 7 days after the soaking time, wrinkled skin, blistering, peeling, softening, discoloration, loss of light film surface.

Salt fog for 500 hours, marking: single corrosion <=2mm,

Uncrossed area: no abnormal

There are 2 pieces of three samples without blistering, cracking, peeling, off powder, obvious discoloration, obvious loss of light as abnormal

The resistance to artificial weathering for 800 hours, <=2 <=2 lost light color

No abnormal phenomenon of pulverization, blistering, cracking, spalling etc.

Please refer to the supplier standard thickness 60um~80um-

101 Chinese brand pencil drawing pencil, pencil fixed, with 750 grams of load, 45 degrees of pressure in the film plane, to see if there are more than 3mm following injury:

Plastic deformation: indentation film surface permanent, but no cohesive failure.

Cohesive failure: there are visible scrapes or scratches the surface.
