Incoming Quality (IQA)
Before raw bar stock is unloaded, we verify Material Test Certificates (MTC). We conduct strict spectro-analysis and hardness testing to ensure the steel grade matches your exact automotive tensile requirements.
Zero Defect Engineering
Quality Policy & Compliance
Quality at Annectotech LLP is not an end-of-line sorting activity; it is engineered directly into the machining process. Operating in Faridabad, we enforce rigorous digital metrology, Statistical Process Control (SPC), and strict PPAP compliance to guarantee zero-defect automotive components.
Proactive Engineering
From Defect Detection to Defect Prevention.
In high-volume Traub and secondary drilling operations, producing thousands of parts per shift means that a minor tooling deviation can instantly multiply into a massive rejection rate. For Tier-1 automotive assembly lines, accepting out-of-tolerance components is simply not an option.
At Annectotech LLP, we have built a proactive quality culture. Rather than waiting to inspect parts after they are finished, our machine operators and quality engineers utilize real-time Statistical Process Control (SPC) on the shop floor. By measuring parts at standardized intervals and plotting dimensional trends, we predict and correct tool wear before a component ever falls out of the CAD tolerance band.
- ISO & ZED Aligned: Quality Management Systems (QMS) strictly adhering to ISO 9001 protocols and MSME Zero Defect initiatives.
- Empowered Workforce: Every machine operator has the authority to instantly halt production if a dimensional drift is detected.
Comprehensive Inspection
The Three Pillars of Verification
Our quality assurance is broken down into three distinct operational phases to ensure complete traceability and metallurgical integrity from raw steel to finished part.
In-Process Control (IPQC)
First-article setup must be signed off by a senior engineer. Operators then conduct routine gauge checks every 30 minutes, feeding data directly into our digital SPC tracking system to maintain Cpk targets.
Final Assurance (FQA)
Prior to packaging, batches undergo randomized AQL sampling. Parts are checked for surface roughness ($R_a$), visual burrs, rust prevention oil coating, and final Go/No-Go thread fitment.
Standardized Measurement
The Metrology & Calibration Lab.
Precision cannot exist without accurate measurement. At our Faridabad headquarters, Annectotech LLP maintains a dedicated, temperature-controlled metrology laboratory.
We rely exclusively on high-end digital measuring instruments—including Mitutoyo micrometers, optical profile projectors, and surface roughness testers. To ensure absolute compliance, every instrument and thread gauge on our factory floor is cataloged and subjected to a strict NABL-traceable calibration schedule. If a gauge is past its calibration date, it is instantly locked out of the production system.
- Optical Profile Verification: 50x / 100x Magnification checks.
- Dimensional Limits: Accurate down to ± 0.005 mm (± 5 µm).
- Surface Finish: Digital $R_a$ & $R_z$ Profilometers deployed.
Engineering Tolerances
Standard Verification Matrix
The rigorous inspection parameters and instrumentation used to verify our precision Traub components and secondary sub-assemblies.
| Quality Parameter | Standard Automotive Tolerance | Primary Verification Instrument | Inspection Stage |
|---|---|---|---|
| Outer Diameter (OD) | ± 0.01 mm to ± 0.05 mm | Digital Micrometers / Snap Gauges | IPQC (Every 30 Mins) |
| Internal Threads | 6H Class Fit | Calibrated Thread Plug Gauges | 100% Go/No-Go Verification |
| Cross-Hole Intersection | True Position ± 0.05 mm | Optical Profile Projector / CMM | First Article & FQA Sampling |
| Surface Roughness | $R_a$ 0.4 µm to 1.6 µm | Digital Surface Profilometer | FQA (Pre-Dispatch Batch Test) |
Automotive OEM Standards
New Product Development (PPAP)
When introducing a new high-volume component, we follow strict Advanced Product Quality Planning (APQP) frameworks to eliminate risks before mass production begins.
01
Feasibility & PFMEA
We conduct a Process Failure Mode Analysis (PFMEA) to identify potential machining risks and implement Poka-Yoke fixtures to prevent them.
02
Control Plans
A highly detailed Control Plan is drafted, specifying the exact micrometers, gauges, and inspection frequencies required for every dimension.
03
Initial Sample (ISIR)
An initial batch is machined. The First Article Inspection Report (ISIR) is generated and submitted alongside raw Material Test Certificates.
04
Level 3 PPAP
Once the client signs off on the Part Submission Warrant (PSW) and the Cpk targets are met, the component is cleared for bulk dispatch.
Lifetime Accountability
100% Forward & Backward Batch Traceability
In the automotive industry, component recalls are devastating. Every corrugated box that leaves our Faridabad facility features a unique barcode and Batch Lot Number. If an issue arises in the field years down the line, we can trace that specific part number backward through our ERP system to identify the exact machine operator, the date of manufacture, the calibration status of the micrometers used, and the original steel mill's heat number from the raw Material Test Certificate (MTC).
