The Problem

Veining defects cost your foundry — every day

When molten metal contacts a sand core, silica expands rapidly under extreme heat. This thermal expansion causes the binder matrix to crack — creating gaps through which liquid metal intrudes. The result is fin-like metal projections, called veins, that form along the surface and internal features of your castings.

Veining is one of the most persistent and costly defects in ferrous casting. Fins lodged in internal passages are often impossible to remove during fettling — forcing full casting rejection. The downstream impact is severe: elevated scrap rates, rework hours, missed dispatch schedules, and ultimately, damaged customer relationships. Every rejected casting from veining represents preventable cost.

The Solution

Veinseal™ — Global Innovation, Locally Delivered

Veinseal™ is an engineered sand additive. A unique blend of superior quality materials that prevents thermal deformation or cracking of silica. When mixed into your core sand with resin, it controls expansion before it causes defects — eliminating veining at the source, not after the fact.

Prince Minerals LLC is a multinational corporation producing premium foundry supplies with decades of global deployment. As their authorized distributor in India, Samarth Metallurgicals delivers Veinseal™ alongside full technical support — from trial setup to grade optimization and process integration.

Compatibility

Compatible with all core processes

Veinseal™ integrates seamlessly into your existing mixing workflow — no new equipment, no process overhaul required.

Shell Cores

RCS-based shell cores with Veinseal™ additive blended into the coating mix. Optimal for high-volume, thermally demanding grey and ductile iron applications.

Coldbox Cores

For no-bake and coldbox applications. Veinseal™ works with amine-cured and CO₂-cured systems, maintaining core strength while controlling sand expansion.

No-Bake Cores

For organic and inorganic no-bake systems. Veinseal™ inorganic formulations deliver no LOI penalty, making them ideal for clean, high-quality steel castings.
