We offer reliable pressure testing for components and castings up to 2 tonnes.
Our capabilities include bubble, hydro, resin, air pressure, and vacuum leak testing to identify leaks, verify integrity, and support porosity sealing processes.
Did you know?
Porosity sealing can recover castings that would otherwise be scrapped, sealing microscopic leak paths without changing the part’s dimensions or performance. A smarter solution for reducing waste and improving reliability.
Porosity is a common issue in cast metal parts and it’s not always visible on the surface. Even with modern casting methods, small voids from shrinkage or trapped gas can lead to leaks once parts are machined or put under pressure.
Our Dot Peen marking service provides fast, reliable and permanent identification for your parts. Using a tungsten carbide stylus, a series of precise dots are driven into the surface to create clear, durable markings that won’t fade or wear away.
Porosity sealing eliminates micro-voids in castings, preventing fluid and gas leaks while maintaining the component’s original dimensions and strength.
Porous castings? We fix that. Our vacuum impregnation process seals leaks, strengthens components and extends part life—helping manufacturers avoid waste and downtime.
Pressure testing is a critical quality control process for components and castings — helping identify leak paths and verify integrity before or after porosity sealing.
Microscopic pores in metal castings can lead to leaks and failures. We fix it with our porosity sealing, improving reliability and extending component life.
As the year comes to a close, we’d like to thank our customers, partners, and the entire ISL team for another successful year.
We wish you a very Merry Christmas and a happy, healthy New Year. 🎄✨
Thank you for your continued support — we look forward to what 2026 brings.
Our Dot Peen Marking delivers deep, sharp results using a tungsten carbide stylus for high-contrast text, logos and Data Matrix codes.

Did you know? Porosity describes how much air and moisture your material can hold — and untreated porosity is what lets stains, water, and damage seep in. Protect your surfaces with the right impregnation to maintain strength and appearance
From low-pressure bubble testing to high-pressure hydro and resin-based methods, our facilities cover the full spectrum of pressure testing. We guarantee accurate, traceable outcomes so your products meet the toughest standards.
Up to 90% of casting rejections are due to porosity.
Porosity sealing—fills internal voids without altering part geometry, restoring pressure integrity and preventing fluid or gas leakage.
Reliable pressure testing up to 2 tonnes — we offer in-house pressure testing to ensure every component is leak-free and production-ready!
