Quality Assurance
At Rajal Industries, quality is our priority. We are committed to manufacturing high-performance industrial fasteners and precision-engineered components that meet global standards for durability, strength, and precision. Every product undergoes rigorous quality control, from raw material selection to final inspection, ensuring that our customers receive defect-free and reliable fastening solutions.
With ISO 9001:2015 certification, CE marking, and compliance with ASTM, DIN, ISO, and IS standards, we follow a zero-defect manufacturing approach to guarantee the best quality fasteners for industrial, structural, and automotive applications.
Our Quality Management System (QMS)
Our ISO 9001:2015 certified Quality Management System (QMS) is built around systematic inspections, material traceability, and multi-stage testing procedures to ensure consistent performance and reliability in every batch.
- Raw Material Inspection – Verifying steel, alloys, and coatings for strength and composition.
- In-Process Quality Control (IPQC) – Real-time monitoring of machining, threading, and forming processes.
- Final Product Inspection – Ensuring fasteners meet dimensional accuracy, mechanical properties, and surface finish standards.
- Batch Certification & Traceability – Providing Material Test Certificates (MTCs), Lot Traceability & Compliance Documents.
- Continuous Process Improvement – Investing in R&D, automation, and lean manufacturing for better quality and efficiency.
Multi-Stage Testing & Inspection Procedures
To ensure durability, tensile strength, and corrosion resistance, all our fasteners and precision components undergo stringent testing using advanced inspection tools and laboratory facilities.
Raw Material Testing
We use high-grade raw materials, including mild steel, stainless steel (304, 316), high-tensile alloy steel, and specialty coatings.
- Spectro Analysis (Spectrometer Testing) – Verifies chemical composition and material purity.
- Hardness Testing (Rockwell & Brinell) – Ensures ccorrect mechanical properties for strength and wear resistance.
- Tensile & Yield Strength Testing – Confirms that fasteners can withstand industrial loads without failure.
In-Process Quality Control (IPQC)
Our real-time quality monitoring during production ensures that every fastener meets design specifications and international standards.
- Dimensional Accuracy Check – Using Vernier calipers, micrometers, and thread gauges for precision.
- Thread & Pitch Inspection – Ensuring perfect fitment, threading depth, and uniformity in bolts & screws.
- Torque & Shear Strength Testing – Checking fastenerload-bearing capacity and impact resistance.
- Plating & Coating Thickness Measurement – Ensuring optimal corrosion resistance and longevity.
