* Plate selection

　　It is best to consider both the application and the cost of the product when choosing a plate, for example, if you want to reduce the thickness of the plate, you can only use a slightly more expensive alloy as a material. The hardness and strength of the plate also directly determine the size and arrangement of the holes. And you should know that the plates that are commonly used are more acceptable than the special requirements. The types of sheets we can provide you with include: stainless steel, carbon steel, zinc sheet, galvanized sheet, aluminum sheet, brass, copper, plywood, fiberboard, rubber sheet, cardboard, wood board, aluminum-magnesium alloy sheet, nickel sheet, fiberboard, PVC sheet and a wide variety of composites. Thin sheets are easier to use for punching holes, and they are also less expensive. Under the premise of complying with the principle of minimum pore size, the appropriate plate thickness is more conducive to increasing the compressive strength of the product. Plates generally have certain tolerances. The thickness of the sheet we can punch is between 0.1mm-25mm. The specifications of the board are generally 1000mm*2000mm, 1000mm*N meters coiled plate.

　　*aperture

　　Generally speaking, the aperture should be greater than or equal to the thickness of the plate, that is, it should conform to the principle of minimum aperture diameter. The closer your required hole size is to the thickness of the plate, the more difficult it is to process and the higher the processing cost. In some materials, the aperture can be smaller than the thickness of the sheet. The hole diameter we make can be as small as 0.08mm.

　　*Hole spacing

　　Center distance is the distance between the center of a hole and the center of another nearest hole adjacent to it. The center distance is one way to express the spacing of holes, and the other is the opening ratio. The essence of these two representations is the same.

　　*Open porosity

　　The porosity refers to the ratio of the area of the hole to the total area of the plate, which can be expressed as a percentage. You must be aware that the pressure of the punching equipment can cause the deformation of the plate, and the larger the opening ratio, the more obvious the deformation of the plate, especially if there are no edges at the four corners. This deformation can be leveled by a special machine in our workshop, so you need to carefully consider the special requirements for leveling and ask us.

　　* Leave edges

　　Edge retention refers to the non-perforated area of the edge of the sheet. A typical orifice plate is one with a long edge that needs to be left behind. If you have special requirements, you need to provide us with the size of the four sides. It may affect the edge due to production reasons. If it is not suitable for your requirements, we will provide similar products with your consent.
