LED stamping aluminum lamp enclosure metal lamp cup stamping parts moulds cup metal die stamping molding parts

Metal stamping parts are mainly formed by stamping metal sheets through stamping dies with the help of the pressure of a press. It mainly has the following characteristics:
⑴ Stamping parts are produced by stamping under the premise of low material consumption. The parts are light in weight and good in rigidity. After the sheet metal is plastically deformed, the internal structure of the metal is improved, which improves the strength of the stamping parts. .
(2) Stamping parts have high dimensional accuracy, are uniform in size with the molded parts, and have good interchangeability. General assembly and use requirements can be met without further machining.
(3) Stamping parts have good surface quality and smooth and beautiful appearance during the stamping process because the surface of the material is not damaged, which provides convenient conditions for surface painting, electroplating, phosphating and other surface treatments.

Quality Assurance
Product Inspection Process
touch test
Wipe the surface of the outer cover with a clean gauze. The inspector needs to wear touch gloves and touch the surface of the stamping part along the longitudinal direction of the stamping part. This inspection method depends on the experience of the inspector. If necessary, the detected suspicious area can be polished with oilstone and verified, but this method is an effective and quick inspection method.
Whetstone grinding
1. First wipe the surface of the outer cover with a clean gauze, then polish it with a whetstone (20×20×100mm or larger), use a relatively small whetstone for places with arcs and hard-to-reach places ( For example: 8×100mm semi-circular whetstone)
2. The choice of oil stone particle size depends on the surface condition (such as roughness, galvanizing, etc.). A fine-grained oilstone is recommended. The direction of the oilstone grinding is basically along the longitudinal direction, and it fits the surface of the stamping part well, and some special places can also supplement the horizontal grinding.
Flexible gauze sanding
Wipe the surface of the outer cover with a clean gauze. Use a flexible sand net to closely adhere to the surface of the stamping part and grind it longitudinally to the entire surface. Any pitting and indentation will be easily found.
oil inspection
Wipe the surface of the outer cover with a clean gauze. Then use a clean brush to apply oil evenly along the same direction to the entire outer surface of the stamping. Put the stamped parts coated with oil under strong light for inspection. It is recommended to stand the stamped parts on the body position. With this method, it is easy to find tiny pits, pits, and ripples on the stamping parts.
visual inspection
Visual inspection is mainly used to find abnormal appearance and macroscopic defects of stamping parts.
Gage inspection
Put the stamping parts into the inspection fixture, and inspect the stamping parts according to the operation requirements of the inspection fixture manual.
production issues safe production
In actual production, technological tests similar to the stamping process are commonly used, such as deep drawing performance test, bulging performance test, etc. to test the stamping performance of materials to ensure the quality of finished products and a high pass rate.
