FOUNDRIES
Metal Analysis Solutions for Foundries & Casting Facilities
Foundries are the backbone of metal component manufacturing, producing high-quality cast alloys for industries ranging from automotive and aerospace to construction and energy. To ensure consistency and compliance, foundries must deliver accurate chemical composition reports that meet stringent material grade standards.
ARUN Technology has been a trusted partner to the metal casting industry for over 35 years, supplying advanced Optical Emission Spectrometers (OES) designed for precision alloy analysis. Our instruments are used worldwide to support everything from quick grade sorting to in-depth elemental analysis, including trace element detection.
With fast, accurate results and a user-friendly software interface, ARUN’s OES systems streamline quality control at every stage of the melt process. We also offer custom calibrations for a broad range of steels, aluminium alloys, copper, and other non-ferrous metals, ensuring reliable performance across all material types.

The HELIUS XRF series of metal analysers are a good choice for analysis in many fields; delivering rapid and accurate results right in the palm of your hand. Due to the advanced electronics and state-of-the-art mathematical algorithms, the HELIUS XRF instruments provide ultimate quality of measurement within a couple of seconds.
MERLIN 4 (OES)
Reliable Alloy Verification for Foundries
The MERLIN 4 is a robust mid-range CMOS Optical Emission Spectrometer, ideal for the day-to-day analytical demands of foundries and metal casting facilities. Available as both a dedicated single-base unit and a versatile multi-base system, it’s designed to handle a wide range of applications—from ferrous to non-ferrous alloys.
​
Choose from two models:
-
MERLIN 4 Ultra: Wavelength range 175–521 nm
-
MERLIN 4 Visible: Wavelength range 201–521 nm
Both models provide coverage for the essential calibration elements required for accurate melt control, incoming material verification, and final quality checks.
Built for efficiency, precision, and ease of use, the MERLIN 4 integrates seamlessly into foundry workflows, helping ensure every batch meets required specifications and industry standards—supporting reliable, repeatable results shift after shift.
CALIBUS (LIBS)
The CALIBUS is our laser-induced breakdown spectrometer (LIBS). It is the first and only CMOS-based LIBS analyser in the market to measure carbon in ferrous. The new CALIBUS is an ideal analytical solution for QA/QC, metallurgical manufacturing and machining, petrochemical industries, mining, scrap metal and recycling.
ARTUS 8 (OES)
High-Performance Analysis for Foundry Melt Control
The ARTUS 8 is engineered to deliver fast, precise, and highly accurate elemental analysis—making it the ideal solution for melt monitoring and quality control in foundries. Whether you're casting iron, steel, or complex alloy systems, the ARTUS 8 ensures each melt meets the required specifications before pouring.
​
Supporting a full range of analytical programmes—including cast irons, carbon- and nitrogen-containing steels, and essential alloying and trace elements—the ARTUS 8 gives foundries the confidence to certify material grades and maintain process consistency.
​
Built on advanced CMOS technology, this versatile and powerful spectrometer combines flexibility with performance. In fact, it rivals traditional photomultiplier-based systems, making it a cost-effective yet uncompromising choice for high-demand foundry environments.
