One Pass Double Sides Automatic Sand Blasting Machine For Stainless Steel Sheets

The double sides automatic sand blasting machine for stainless steel sheets is a specialized surface treatment equipment designed for high-efficiency, uniform sand blasting of both sides of stainless steel sheets in one operation. Its core capabilities include the following:

• Dual-side Synchronous Blasting: Equipped with two sets of independent blasting systems (upper and lower) that work synchronously, ensuring consistent surface roughness, cleanliness, and texture on both sides of the stainless steel sheet without secondary flipping operations.
• Precise Parameter Control: Supports adjustable key parameters such as blasting pressure (0.2–0.8 MPa), abrasive flow rate (50–200 kg/h), conveyor speed (0.5–5 m/min), and nozzle swing frequency (0–30 times/min). This allows customization of surface effects to meet different requirements (e.g., decorative matte finish, pre-coating roughening).
• Intelligent Automatic Operation: Integrated with PLC control system, it realizes automatic feeding, positioning, blasting, dust removal, and discharging. It can be linked with upstream and downstream production lines (e.g., sheet cutting machine, coating line) to form a fully automated production process.
• High Abrasive Recycling Rate: Adopts a cyclone separation + pulse dust removal integrated system, with an abrasive recycling rate of up to 95% or more. It separates reusable abrasives from dust and impurities, reducing material waste and environmental pollution.
• Stable Sheet Conveying: Uses roller or belt conveyor with anti-slip and positioning devices, suitable for stainless steel sheets with thicknesses of 0.3–10 mm and widths of 300–2000 mm, ensuring no deformation or displacement during blasting.
• Environmentally Friendly Dust Removal: The pulse jet dust collector has a dust removal efficiency of over 99.5%, meeting national industrial emission standards, and avoiding dust leakage to protect the workshop environment and operator health.

This equipment is widely used in the surface treatment of stainless steel sheets in multiple industries, mainly including:

• Kitchenware and Sanitary Ware Industry: Surface treatment of stainless steel kitchen cabinets, sinks, range hood panels, bathroom mirrors, and shower room frames, to achieve a uniform matte or brushed texture and enhance corrosion resistance and decorative effect.
• Building Decoration Industry: Processing of stainless steel decorative panels, curtain wall panels, elevator car panels, and handrails, improving the adhesion of coatings or films and ensuring consistent appearance of decorative surfaces.
• Home Appliance Manufacturing Industry: Surface roughening treatment of stainless steel shells of refrigerators, washing machines, microwave ovens, and water heaters, to prepare for subsequent processes such as spraying and bonding.
• Automotive and Aerospace Industry: Surface cleaning and roughening of stainless steel structural parts, exhaust system parts, and aircraft interior panels, removing oxide scales and oil stains and improving the bonding strength of coatings.
• Electronic and Electrical Industry: Surface treatment of stainless steel shells of precision electronic instruments, switch cabinets, and distribution boxes, to achieve insulation, anti-corrosion, and anti-fingerprint effects.

The models are usually named according to the maximum processing width of stainless steel sheets, and the common models include:

• Automatic sheet loading and unloading robot arm
• Abrasive type automatic switching system (suitable for switching between steel grit, steel shot, and ceramic sand)
• Online surface roughness detector
• Anti-fingerprint spraying device after blasting
• Remote monitoring and fault diagnosis system
