Problems solved by technology
[0002] At present, there are two kinds of card holder bodies popular on the market, mainly the card holder body made by powder metallurgy (MIM) and the card holder body made by plastic molding steel sheet process, among which the card holder body made by powder metallurgy (MIM) The main body of the card tray has a complicated manufacturing process, low product stability, and high product prices; the main body of the card tray made of plastic molding steel sheet technology is not strong enough, easily deformed and warped, and cannot adapt to the needs of the entire mobile phone market. The demand for high cost performance of mobile phone card holders; therefore, the traditional card holder body made by powder metallurgy (MIM) and the card holder body made by plastic molding steel sheet technology cannot meet the needs of the market.

Embodiment Construction
[0017] Such as Figure 1-Figure 5 As shown, this specific embodiment adopts the following technical scheme: it includes an upper steel sheet 1, a lower steel sheet 2 and a plastic sleeve 3, and the upper steel sheet 1 and the lower steel sheet 2 are stacked and welded into one metal skeleton, and the outer periphery is wrapped with Plastic sleeve 3.
[0018] Wherein, the thickness of the upper steel sheet 1 is 0.15 mm; the thickness of the lower steel sheet 2 is 0.3 mm.
[0019] The production process of this specific embodiment: a, stainless steel type selection: select different thicknesses and material hardness according to product characteristics; It is fed into the stamping die and stamped according to the structural characteristics of each layer. After the stamped waste is removed, the structure of each layer is restrained by the material tapes on both sides. The function of the material tape is to arrange each product in an orderly manner. The positioning holes on the...

Abstract
The invention discloses a double-layer steel sheet laminated and welded plastic cell phone clamping holder which relates to the technical field of cell phone holder. The clamping holder comprises an upper steel sheet, a lower steel sheet and a plastic sleeve. The upper steel sheet and the lower steel sheet are laminated and welded into an integrated metal frame. The four corners around the metal frame are wrapped by the plastic sleeve. According to the invention, the two steel sheets are firstly laminated and welded and then subjected to plastic molding. In this way, the product becomes more intense and does not deform easily. As the four corners of the holder are wrapped by plastic, an insulation effect can be achieved. The thickness of such double-layer steel sheets could be above 0.45mm after being welded, a sharp increase in the entire intensity from the currently available 0.3 mm thick single layer steel sheet after plastic molding. And at the same time, an insulation effect could be achieved. Therefore, the clamping holder of the invention can find wide applications in the market with its more stable performances.
