At FREXTO CAST SOLUTION PRIVATE LTD., we are committed to delivering excellence through a robust and technologically advanced infrastructure. Our facility, set to launch in May 2025 at Katrambakkam, Chennai, is designed with end-to-end systems and control mechanisms to support the complete aluminium casting process — from concept to seamless launch of products to the market.

We integrate cutting-edge machinery, automation, and stringent quality control processes to ensure that every casting meets the highest standards of precision, consistency, and reliability. Below is an overview of our key facilities:

1. Melting & Holding Furnaces

We are equipped with 500 kg capacity electrical hydraulic tilting furnaces for efficient and consistent alloy melting. These furnaces ensure uniform temperature control and enhanced energy efficiency. To support uninterrupted production, we also have 500 kg capacity electrical holding furnaces for continuous feeding into the casting process.

Understanding the importance of core quality in casting, we maintain a dedicated *sand testing laboratory* for incoming and in-process inspections. Equipment includes:

  • Sieve Analyzer for AFS Testing
  • Hot Tensile Strength Tester
  • Core Hardness Tester
  • Digital Core Gas Determinator
  • Peel Back Inspection.

These instruments ensure every shell core meets structural and thermal performance criteria, resulting in better dimensional accuracy and durability of the final castings.

Our advanced CCD-based Arc Spark Optical Emission Spectrometer allows precise analysis of aluminium alloy composition during melting. This fully digital, current-controlled spectrometer ensures:

  • Accurate and repeatable results across batches
  • Multi-base functionality without limitations
  • Scalable architecture that adapts to user requirements
  • Integrated re-standardization with single sample analysis

This tool is essential for batch-wise composition validation and maintaining metallurgical integrity.

To produce intricate core profiles for Gravity Die Casting (GDC), we utilize an automated double-shoot rollover shell core machine. Equipped with:

  • Die temperature sensing
  • Shooting and investment time monitoring
  • Poka-yoke systems for corebox temperature
  • PLC integration to prevent operation whenever out-of-spec conditions

This ensures precise and repeatable core making aligned with casting specifications.

Our tilting-type die casting machine supports both vertical and tilt pouring processes, offering flexibility for various casting applications. The machine features:

  • Rigid hydraulic cylinder mechanism
  • Die temperature and tilt angle monitoring
  • Poka-yoke and PLC-based operational controls

This system ensures consistent quality and eliminates human error in critical casting parameters.

To maintain metallurgical purity, we employ a mobile degassing unit with a graphite rotor and sleeve system for removing hydrogen gas using nitrogen. Features include:

  • Uniform bubble formation for effective degassing
  • Flow control valve for nitrogen regulation
  • Integrated poke-yoke for gas availability into N2 Cylinder.

This prevents gas porosity and ensures dense, defect-free castings.

Our post-processing section is fully equipped with:

  • Decoring Machines for sand removal
  • Band Saw Cutting Machines
  • Linishing Belt Grinders
  • Dedicated tables for 100% Line Inspection.

These operations ensure components are refined, deburred, and validated before dispatch, enhancing finish and function.

We utilize CNC machining centers to perform precision operations such as drilling, milling, turning, and threading on cast components. These systems ensure consistent accuracy across large production runs and enable complex contouring with minimal tolerance variations.

Key Highlights:

  • High-speed, multi-axis machining
  • Precision surface finishing and geometry control
  • Ideal for automotive, aerospace, and industrial parts
  • Supports both ferrous

Our VMCs are integral for high-precision vertical milling tasks, especially on complex cast components. These machines are ideal for intricate part geometries and critical dimensional tolerances required in prototype and production casting applications.

Key Highlights:

  • Vertical spindle with multi-tool turret
  • Enhanced stability and rigidity during operation
  • Accurate profiling, slotting, and cavity machining
  • Seamless integration with CAD/CAM software for design-based machining

To ensure the dimensional accuracy and conformance of our products, we use CMM inspection systems for final quality checks. These machines verify critical dimensions, surface flatness, and geometric tolerances with micrometer-level precision.

Capabilities

  • 3D coordinate-based measurement
  • Digital inspection reports with deviation analysis
  • Essential for prototype validation and serial production quality control
  • Reduces human error and ensures consistent part quality

With these facilities, FREXTO CAST SOLUTION PRIVATE LTD. is poised to become a trusted partner for aluminium casting needs, delivering innovation and precision at every step.
