Choosing Between Tempered and Laminated Glass for Your Waterjet Cutting Project
When planning a precision cutting project involving glass materials, understanding the fundamental differences between tempered and laminated glass can save you time, money, and frustration. Each type offers distinct advantages and limitations that directly impact your waterjet cutting options and project outcomes.
Understanding Tempered Glass and Its Waterjet Cutting Challenges
Tempered glass is an exception for waterjet cutting, since this type of glass is designed to shatter into pieces whenever it is punctured. Tempered glass, known for its high strength (65–150 MPa surface stress), cannot be cut directly due to its stress-balanced structure, which shatters upon compromise. This fundamental limitation stems from the tempering process itself, which creates internal stresses that make the glass incredibly strong but also prone to complete failure when compromised.
No, it is not possible to cut tempered glass with a water jet cutting machine. Among all materials, only tempered glass cannot be cut with a water jet cutter. However, there’s an important workaround: tempered glass must be cut before tempering. This means manufacturers must complete all cutting operations on annealed glass before the tempering process begins.
For projects requiring tempered glass with custom shapes, waterjet cutting emerges as the only viable solution for tempered glass, but only after annealing (600–650°C treatment) to relieve internal stress. Waterjet cutting—using ultra-high-pressure water (55,000–75,000 psi) and abrasives (0.8–1.2 lb/min garnet)—offers a solution only if paired with pre-annealing.
Laminated Glass: The Waterjet-Friendly Alternative
Unlike tempered glass, laminated glass presents excellent opportunities for waterjet cutting. Yes, water jet cutting machine can cut through laminated glass. In fact, the hardest variety of this glass, such as laminated ballistic glass material, can also be cut with a water jet. Laminated glass consists of two or more layers of glass with a plastic interlayer. When broken, this kind of glass is made to stay together, increasing safety. Waterjet cutting can effectively cut laminated glass, though the process might need to account for the interlayer to ensure clean cuts.
The key advantage of laminated glass for waterjet applications lies in its structural design. Water jet cutting is the ideal solution as it cuts through the layers cleanly without damaging the interlayer or causing misalignment. However, specialized techniques are required to prevent delamination during the cutting process.
Best Practices for Laminated Glass Waterjet Cutting
When attempting to cut laminated glass, the single biggest risk is delamination, and that’s why it’s always best to let a professional do the cutting. Glass waterjet cutting at low pressure would be best in this situation. Professional waterjet services understand the critical parameters needed to maintain the integrity of both glass layers and the interlayer material.
Pre-drilled holes can also reduce the chance of the high-pressure water stream separating the glass layers. This technique helps manage water pressure distribution and prevents the formation of air pockets that could cause delamination during the cutting process.
Manufacturing Applications and Precision Requirements
For manufacturing applications, waterjet cutting delivers exceptional precision on compatible glass types. Modern CNC waterjets offer remarkable precision (tolerances down to +/- 0.1mm or better are achievable), ensuring parts fit perfectly and designs are replicated flawlessly. This level of accuracy makes waterjet cutting ideal for architectural applications, custom installations, and specialized manufacturing projects.
Waterjets enable complex geometries, decorative patterns, custom openings, logos, and artistic designs integrated directly into the laminated glass panel. This design freedom allows manufacturers to create intricate patterns and shapes that would be impossible with traditional cutting methods.

Local services can provide faster turnaround times, direct consultation on material selection, and the flexibility to handle both prototype and production requirements.
Making the Right Choice for Your Project
The decision between tempered and laminated glass for waterjet cutting projects ultimately depends on your specific requirements. If your project demands the safety characteristics of tempered glass, plan to complete all cutting operations before the tempering process. For applications where laminated glass meets your safety and performance requirements, waterjet cutting offers superior design flexibility and precision.
In fact, waterjet cutting is one of the best methods for thin glass since other alternatives can cause the thin glass material to break. This makes waterjet technology particularly valuable for delicate or complex glass cutting applications where traditional methods would pose too high a risk of material failure.
Understanding these material characteristics and working with experienced waterjet cutting professionals ensures your glass cutting project delivers the precision, quality, and reliability your manufacturing applications demand. Whether you’re creating architectural elements, safety glass components, or specialized industrial parts, choosing the right glass type and cutting method sets the foundation for project success.
