Product Overview
The Sand Blasting Glass Machine is an automatic glass surface treatment system for producing frosted finishes, decorative patterns, and controlled matte surfaces on flat glass. It combines three automatic spray guns and one manual spray gun with PLC touchscreen control, allowing continuous batch processing as well as localized or detail blasting. The machine is available in SG1600, SG2000, and SG2500 configurations for different glass widths.

Glass Processing Capability
The machine is designed for flat-glass sandblasting where consistent surface coverage and repeatable processing parameters are required.
Maximum glass width: 1600, 2000, or 2500 mm, depending on model
Typical glass thickness: 3–50 mm, subject to machine configuration
Processing modes: Full automatic blasting and manual spot/detail blasting
Suitable glass: Float, tempered, laminated, and decorative glass
Surface effects: Uniform frosting, matte finishes, privacy patterns, and decorative sandblasted areas
Sand Blasting Workflow
Glass Loading: Place the glass vertically on the synchronous-belt conveying system.
Positioning: The PLC-controlled system positions the glass according to the programmed working area.
Abrasive Blasting: Automatic spray guns move across the designated area at controlled speed and pressure. Aluminum oxide is a commonly used abrasive for glass sandblasting.
Manual Detailing: The manual gun can be used for localized areas or pattern correction where required.
Dust Separation: The dust-removal system separates airborne dust and abrasive particles during processing.
Surface Inspection: Check coverage, frosting density, edges, and pattern consistency before transferring the finished glass to the next process.
Configuration & Line Integration
The standard system includes the PLC touchscreen control, synchronous-belt conveying system, three automatic spray guns, one manual spray gun, and dust-removal system.
For a complete glass-processing workflow, the machine can be positioned after glass cutting and edge processing and before subsequent washing, inspection, or installation-related operations. Model selection should be based on maximum glass width, required throughput, available floor space, compressed-air capacity, and the proportion of automatic versus manual blasting work.
Inspection & Testing
Before shipment, the machine should undergo functional and production-oriented checks covering conveyor operation, blasting-gun movement, nozzle alignment, PLC/HMI functions, abrasive circulation, dust extraction, and safety interlocks.
Trial blasting can be performed using representative glass or customer-approved samples to verify surface coverage, pattern definition, and processing consistency. Wear components such as blasting nozzles, abrasive pipes, seals, and protective linings should also be inspected before dispatch.
FAQ
Q: What abrasive media can be used with the glass sandblasting machine?
A: Aluminum oxide is commonly used for glass blasting because it provides consistent cutting performance and surface texture. The appropriate abrasive grade should be selected according to the required frosting depth, surface appearance, and production speed. Abrasive compatibility should be confirmed before switching to another media.
Q: How often does the abrasive need to be replaced?
A: Abrasive consumption depends on blasting pressure, glass area, surface finish, and recycling efficiency. The abrasive should be screened and replenished regularly rather than replaced at a fixed interval. Excessively worn or contaminated media can affect surface uniformity and increase dust generation.
Q: What compressed-air system is required for operation?
A: A dedicated industrial air compressor is normally required. For the standard machine, a working pressure of 0.6–0.8 MPa and approximately 3 m³/min of compressed air are commonly used. The final compressor specification should be matched to the machine configuration and number of guns operating simultaneously.
Q: What maintenance is required for the sandblasting machine?
A: Routine maintenance includes checking nozzles, abrasive pipes, seals, conveyor components, dust filters, and abrasive circulation paths. Nozzles and abrasive-contact components should be inspected for wear because changes in nozzle condition can affect blasting distribution and surface consistency.
Q: Can the machine be customized for specific production requirements?
A: Yes. Customization can be discussed for requirements such as glass working width, blasting configuration, control functions, conveying arrangement, dust-removal capacity, and plant layout.
Q: How is the required frosting effect controlled?
A: The final frosting effect is influenced by abrasive type and particle size, blasting pressure, gun movement, conveying speed, and the number of blasting passes. For projects requiring a specific visual texture or surface finish, sample testing should be performed to establish suitable processing parameters before batch production.
Q: What installation and after-sales support is normally provided?
A: We can offer installation instructions, operation manuals, commissioning guidance, and remote technical assistance. On-site commissioning can be arranged separately for projects requiring it.
Q: What is the typical delivery time for this machine?
A: A standard delivery time is typically 60–90 days after order confirmation, receipt of the agreed payment, and finalization of technical specifications. Customized configurations may require additional engineering and manufacturing time.
