Introduction of clamping cover: the English abbreviation of cap is mainly used for automatic reflow welder, tape packaging and other products. Now with the complexity of the product appearance, the surface of the product itself is not smooth, and the manipulator can not take the product, so cap or high temperature film are widely used now. According to the shape and spacing of products, the shape of cap is also different. There are vertical clamps, side clamps, plastic clips, and hardware. The appearance of clamping covers greatly improves the efficiency of packaging and production.
