2. Product Features
(I) High strength and durability
The ferrous metal substrate gives the plate excellent tensile and compressive properties. The structure is strengthened by the stamping process, and it has excellent deformation and impact resistance. It can withstand frequent mechanical vibration and external force extrusion in industrial environments, ensuring long-term stable use and extending the equipment maintenance cycle.
(II) Strong functional adaptability
The rich hole design (round hole ventilation and heat dissipation, square hole installation adaptation, special function of special-shaped holes), combined with the customization of the plate shape, can accurately match the needs of equipment ventilation, cable threading, material screening, component fixing, etc., to help optimize the equipment function.
(III) Both protection and practicality

Ferrous metal materials naturally have the protective properties of dust and foreign intrusion. The punching structure not only meets the functional requirements, but also retains the protective base of the metal plate, creating a safe operating environment for the internal components of the equipment, and is suitable for dusty and complex working conditions.

3. Product Details
(I) Processing Technology
Using CNC stamping integrated process, firstly, the black metal sheet is accurately blanked by laser cutting or shearing machine to determine the basic size of the plate; then, the CNC punching machine is used to complete the punching operation according to the mold pattern to ensure the hole accuracy (aperture tolerance ±0.1mm); for bending and flanging needs, the bending machine is used for secondary processing to shape the three-dimensional structure of the plate. The whole process relies on automation equipment and digital control to achieve efficient production and high-precision control to meet large-scale orders and customization needs.
(II) Applicable materials
1. Carbon steel: low cost, high strength, easy to process and shape, suitable for scenes with high strength requirements and relatively dry working conditions, such as ordinary mechanical housings and indoor electrical control cabinet perforated plates.
2. Cast iron: outstanding wear resistance and shock absorption, often used for perforated screen plates of high-wear equipment such as mining screening and material transportation, which can effectively resist material impact and friction.
(III) Quality Inspection
Build a multi-layer quality inspection system: Appearance inspection uses manual visual inspection + machine vision to check for defects such as hole burrs, board scratches, and deformation; size inspection uses a two-dimensional imager and a three-dimensional coordinate measuring machine to verify the accuracy of parameters such as board length and width and hole spacing; performance inspection includes tensile testing (verifying tensile strength) and salt spray testing (evaluating corrosion resistance, applicable to special coated boards) to ensure that the product meets industrial quality standards and ensures stable operation of the equipment.
