Galvanized Color Coated Coil Deep Processing (Punching Process) and Product Application Description
I. Process Overview
Punching of galvanized color coated coils is a deep processing procedure that uses CNC punching equipment to form regular or customized holes on the sheet surface. Relying on the coating protection and weather resistance of galvanized color coated coils, combined with precision punching technology, this process can not only retain the anti-corrosion and aesthetic advantages of the base material but also endow the product with additional functions such as ventilation, light transmission, and decoration.
II. Detailed Production Process
Raw Material Pretreatment
Uncoil, level, and cut the galvanized color coated coil to size to ensure the flatness tolerance of the sheet is ≤0.5mm/m, and remove surface dust and impurities to avoid scratching the coating or affecting punching precision during the punching process.
Mold and Equipment Debugging
Customize special punching molds according to customer requirements, install them on CNC punching machines, debug mold clearance (controlled at 0.02–0.05mm), punching pressure and positioning coordinates, and set core parameters such as hole diameter and hole pitch.
Precision Punching Forming
Use an automatic feeding system to send the sheet to the punching station, and complete hole processing through continuous punching. The key precision indicators are as follows:
Hole diameter tolerance: ±0.05mm for holes of Φ2–Φ20mm; ±0.1mm for holes of Φ21–Φ50mm
Hole pitch tolerance: ±0.1mm
Burr height at punching edge: ≤0.02mm
Post-treatment Process
After punching, deburr, grind the edges and corners, perform touch-up painting protection on the cuts (optional), and finally clean, dry, re-coil or cut to size to ensure no damage to the product surface and no peeling of the coating.
III. Uses and Application Scope of Punched Products
Architectural Decoration Field
Perforated exterior wall decorative panels, indoor ceiling sound-absorbing panels, partition screens: Utilize holes to achieve light and shadow effects and noise reduction functions, suitable for public buildings such as shopping malls, airports, and stadiums.
Curtain wall ventilation panels: Balance the needs of building appearance and air circulation, and improve wall air permeability.
Industrial Function Field
Mechanical equipment protective covers, filter screens, heat dissipation orifice plates: Used in power distribution cabinets, fans, environmental protection equipment, etc., to play a protective and heat dissipation role.
Agricultural facilities: Greenhouse ventilation orifice plates, breeding fences, which are corrosion-resistant and convenient for light transmission and ventilation.
Home Furnishing and Transportation Field
Furniture decorative panels, kitchen and bathroom storage racks: Improve aesthetics through customized hole patterns.
Automotive interior parts, carriage ventilation orifice plates: Rely on the lightweight and corrosion resistance of galvanized color coated coils to meet the needs of transportation tools.
