How to identify signs of the production process?

Aluminum alloy profile requirements:

   1. Aluminum alloy profiles and common plastic material accessories should meet the quality requirements of aluminum alloy sign profiles.

   2. The angular base deviation of aluminum alloy profile is less than 1 degree of positive and negative deviation.

   3. Plane gap <=0.4%*B (B is the width of the profile).

   Acrylic sign processing requirements:

   1. Acrylic is ejected from the mold and formed by hot bending, with the same size and shape, and no bubbles and scratches on the surface.

   2. After hot bending, the surface is treated with coarse sand, fine sand and milling to ensure its smooth surface without steps.

   3. After finishing, the surface gloss is soft and uniform, no particles, no bubbles, and even light transmission.

   Stainless steel process requirements:

   1. The stainless steel plate must be pitted and bent and welded (the stainless steel plate must be pitted first and then bent to ensure the edge straightness); ensure that the arc angle of the bend is R<1MM.

   2. Remove the surface oil stains before welding to reduce defects such as false welding, pores, and cracks formed by the weld.

   3. After welding, polish all visible welds smoothly, as smooth as the surrounding surface, without obvious scratches.

   Paint process requirements:

   1. A series of surface treatments such as cleaning surface residues, filling dust, and polishing.

   2. The use of environmentally friendly high-quality paint baking finish treatment. The paint room must be a dust-free and particle-free workshop, and the surface of the paint shall be three-coated and three-baked, and the coating thickness shall be greater than or equal to 35 microns.

   3. The paint color should meet the requirements of the design plan.
