Some process requirements for the production of signs

The current advertising production field has been very mature, the common advertising production materials on the market and the installation process can be said to be close to the degree of unity, but there are also some small manufacturers in the control of materials have defects, so do you know some of the process requirements of Wuhan sign production?
1, aluminum alloy profile requirements
Meet the quality requirements of aluminum alloy plate profile. The angular base deviation of aluminum alloy profiles is less than 1 degree. Plane clearance <=0.4%*B (B is the width of the profile).
2, acrylic signs processing requirements
Consistent size and shape, no bubbles and scratches on the surface. The surface is treated with coarse sand, fine sand and grinding to ensure smooth surface without step. After completion, the surface luster is soft and uniform, no particles, no bubbles, uniform light transmission.
3, stainless steel process requirements
Stainless steel plate must be gouged and bent (stainless steel plate must be gouged and then bent to ensure the edge is straight); Ensure that the arc Angle R at the bending point is less than 1MM. Remove the oil on the surface and reduce the defects such as virtual welding, porosity and cracks formed by the weld. After welding, all visible welds are polished smooth, as smooth as the surrounding surface, without obvious scratches.
4, paint process requirements
A series of surface treatments such as cleaning surface residue, filling ash, grinding, etc. Environmental protection paint paint treatment. The paint room shall have no dust particles workshop, and the surface coating of the paint shall be coated three times and baked three times, and the coating thickness shall be greater than or equal to 35 microns.
5, paint color requirements
Paint color to fully meet the requirements of the design scheme. The paint film should be smooth and uniform, and no defects affecting the decorative effect such as flow marks, wrinkles, orange peel, bubbles and inclusions are allowed. Strict attention should be paid to color control, which does not allow excessive color difference with the design drawing.
6, screen printing process requirements
Film printing screen plate, screen printing surface with alcohol or white electric oil to clean the surface. Screen printing color should meet the requirements of the design scheme, the font and pattern strokes are clear, no deformation, sawtooth and other defects. There is no obvious penetration between the color of screen printing graphics and the background color.
7. Finished appearance requirements
After the installation is completed, the sign has a beautiful appearance, no screws on the surface, no scratches, bubbles and obvious uneven color, the paint must have no obvious color difference, and the materials used meet the requirements of the design scheme.
The above is a summary of some process requirements for the production of Wuhan signs.
