From uniform blasting to dynamic process control

In modern glass processing, there is a growing demand for more complex and customized surface finishes.

In this context, Multishading represents an evolution of traditional sandblasting processes.
Developed for Mistral EV+ automatic sandblasting machines, it introduces dynamic pressure control to achieve advanced shading effects.

Unlike constant-pressure systems, Multishading enables controlled gradients directly within the process.

Multi-axis pressure control

The core of Multishading lies in its ability to modulate blasting pressure along the movement of the gun.

The glass is always positioned on its longer side. However, the system adjusts pressure:

• vertically
• horizontally

As a result, shading effects are generated by process control rather than glass positioning.

This allows precise and repeatable transitions across the surface.

Linear, radial and concentric shading effects

With continuous pressure modulation, Multishading enables a wide range of finishes:

• linear gradients
• smooth transitions across large surfaces
• radial shading
• concentric patterns

This flexibility opens new possibilities for both industrial production and architectural glass design.

Optimized processing of circular glass elements

One of the key advantages of Multishading is the ability to process circular geometries efficiently.

Traditionally, these applications require manual adjustments.
However, dynamic pressure control allows the process to adapt to the shape of the glass.

This results in:

• improved surface uniformity
• higher quality finishes
• reduced manual intervention

Integration into industrial workflows

Multishading is designed for industrial environments.

It allows manufacturers to:

• standardize complex processes
• reduce operator dependency
• ensure consistent results

Moreover, it expands production capabilities without changing the machine setup.

Mistral EV+: a platform for advanced glass processing

Multishading is part of the technological evolution of the Mistral EV+ series.

By integrating advanced pressure control, it enables a more flexible and scalable approach to glass surface processing.
