* panel selection
It is better for you to consider both the application of demand and the cost of products when you choose sheet materials. For example, if you want to reduce the thickness of sheet materials, you can only use the alloy with a higher price. The hardness and strength of the plate also directly determine the size and arrangement of the hole. And you should realize that the commonly used sheet is more acceptable than the special requirements. We can provide you with stainless steel, carbon steel, zinc plate, galvanized board, aluminum plate, brass, copper, laminated board, fiberboard, rubber board, board, board, aluminum magnesium alloy board, nickel plate, fiber board, PVC board and various kinds of synthetic materials. Thin sheets are easier to use for punching holes and are cheaper. In accordance with the principle of minimum bore size, the suitable plate thickness is more conducive to increase the product's ability to withstand pressure. Generally, there is a certain tolerance for plate materials. The thickness of the sheet we can make is between 0.1mm and 25mm. The specification of the plate is generally 1000mm*2000mm, 1000mm*N meter coil plate.
Generally speaking, the hole diameter should be greater than or equal to the thickness of the plate, that is, it should conform to the principle of minimum hole diameter. The closer the hole diameter you require is to the thickness of the plate, the more difficult the processing will be and the higher the processing fee will be. In some materials, the aperture can be smaller than the thickness of the plate. The minimum aperture we can make is 0.08mm.
* hole spacing
The center distance is the distance between the center of a hole and the center of the nearest hole to it. Center distance is a way of representing the spacing of holes, and the other is the opening rate. The substance of these two expressions is the same.
* opening rate
The opening rate is the ratio of the area of the hole to the total area of the board, which can be expressed as percentage. You must pay attention to the pressure of the punching equipment can lead to the deformation of the sheet metal, and the higher the opening rate, the more obvious the sheet metal deformation, especially the four corners without the edge. This kind of deformation can be leveled through the processing of a special machine in our workshop. Therefore, you also need to give careful consideration to the special requirements for leveling.
* left side
The left edge refers to the non-punching area at the edge of the plate. A typical orifice is a long side that needs a side. If you have special requirements, you need to provide us with the size of four edges. The edge may be affected by production reasons. If it is not suitable for your requirements, we will provide similar products with your consent.
