Industry Segments We Serve

Precision Engineering and Foundry

The foundry and machining clusters in Coimbatore utilize ovens for core baking, stress-relieving of metal parts, and heat treatment of precision components. These units must maintain absolute thermal vigilance to ensure the mechanical properties of the castings are within specified limits. Inaccurate oven temperatures can lead to core breakage or structural weaknesses in the final casted products. Vega Calibration acts as a vital technical partner by ensuring these furnaces and ovens are calibrated against traceable standards to detect even minor sensor drift. Our NABL-accredited processes help prevent production scrap and safeguard quality, ensuring that your facility remains compliant with international engineering standards and passes rigorous annual audits with technically sound data.

Food Processing and Export

Coimbatore's emerging food industry, including major spice, flour, and snack units in Pollachi Road and Periyanaickenpalayam, relies on industrial ovens for roasting and moisture control. In these high-stakes environments, accurate temperature regulation is a safety mandate under FSSAI and HACCP guidelines to ensure the reliable prevention of microbial growth and consistent product quality. Inaccurate oven temperatures can lead to catastrophic public health risks or massive product recalls. Vega Calibration provides the low-uncertainty calibration required to support these hygienic requirements. By providing technically sound calibration certificates, we help food processors manage the risks associated with thermal deviations and process inconsistencies, ensuring that every safety operation meets the rigorous quality benchmarks expected by consumers.

Pump and Motor Manufacturing

Coimbatore is the "Pump City" of India, housing thousands of units in SIDCO Kurichi, Ganapathy, and Peelamedu that supply a significant portion of the nation's agricultural and industrial pumps. Ovens in these facilities are critical for the curing of varnish on copper windings and the drying of pump castings after coating. Maintaining consistent thermal uniformity is vital; if the varnish is under-cured, it leads to insulation failure, while over-curing makes it brittle. Vega Calibration acts as a vital technical partner by providing NABL-accredited validation that ensures these curing cycles are technically sound. Our precise mapping identifies potential "thermal dead zones," ensuring that every motor component undergoes uniform thermal treatment, thereby enhancing product longevity and reducing warranty claims in the 2026 cycle.

Textiles and Technical Fabrics

As a historic textile powerhouse, Coimbatore’s units in Thudiyalur and the surrounding Sulur belt utilize industrial ovens for fabric drying, color fixation, and the production of technical textiles. In these environments, uneven heating can lead to shade variation (pattas) or inconsistent tensile strength across the fabric roll. Vega Calibration provides specialized validation that accounts for high-capacity load variations and continuous operation patterns. Our NABL-accredited procedures ensure that your heating data remains technically sound and reproducible, which is vital for meeting the stringent quality requirements of global apparel brands. By providing high-resolution calibration, we help textile manufacturers maintain the metrological integrity of their finishing processes.

Industrial Use Cases

Depyrogenation and Sterilization

In the pharmaceutical plants of Coimbatore, hot air ovens are used for the depyrogenation of glassware and equipment. This use case involves maintaining temperatures, typically around 250°C, for a specific duration to ensure the complete destruction of bacterial endotoxins. Any deviation in temperature or time can lead to non-sterile products, posing a severe risk to patient safety. Vega Calibration provides the technical soundness required through NABL-accredited validation (IQ/OQ/PQ), ensuring the oven achieves and maintains the required lethality. We ensure your sensing systems are technically robust, protecting high-value industrial batches. By acting as your expert thought partner in process validation and audit-defense reporting, we help you facilitate successful regulatory inspections and provide metrologically sound data.

Textile Heat Setting and Color Fixation

Textile units in Sulur utilize ovens to support the heat-setting of synthetic fibers. The critical use case requires a highly stable temperature environment to prevent fabric shrinkage or color migration. If the oven output is too high, the fibers may melt or discolor; if too low, the set is not permanent. Vega provides the low-uncertainty calibration required to support these manufacturing requirements. By providing technically sound calibration data, we help manufacturers manage the risks associated with thermal deviations, ensuring that every operation meets the quality benchmarks expected by international buyers.

Core Baking in Foundries

Foundries in SIDCO utilize ovens for baking sand cores to remove moisture and gain strength. The critical use case involves keeping the core at a constant temperature to prevent "fragile cores" or "over-baked cores" that crumble during metal pouring. Inaccurate temperature regulation during this period can lead to casting defects and significant financial loss. Vega Calibration acts as a vital technical partner by ensuring these units are calibrated against traceable standards. Our NABL-accredited processes help prevent hazardous incidents and safeguard production data, ensuring that your foundry remains compliant with international quality norms.

Loss on Drying (LOD) for Material Testing

Engineering labs in Coimbatore utilize ovens for LOD tests to determine the moisture content in raw materials like polymers and sand. The critical use case involves the precise regulation of the internal environment to ensure moisture is removed without degrading the sample. Inaccurate temperature regulation during LOD can lead to incorrect readings, compromising the integrity of the manufacturing process. Vega Calibration provides high-resolution calibration for temperature stability and accuracy, accounting for the unique operational stressors of the lab environment.

Frequently Asked Questions (FAQs)

Q: Why is spatial mapping necessary? Can't I just use a single-point calibration?

A: A single-point calibration only tells you the temperature at the sensor's location. In an oven, air circulation patterns and insulation gaps create temperature gradients. Spatial mapping (9-point or 27-point) is the only way to prove that your entire batch is being heated uniformly, which is a mandatory requirement for pharmaceutical and automotive audits.

Q: How do you handle calibration for Vacuum Ovens where there is no air for convection?

A: Calibration in a vacuum is technically challenging because heat is transferred primarily through conduction via the shelves. We use specialized contact probes or "thermal pads" to ensure accurate measurement of the shelf temperature, which is the actual heating surface for your product.

Q: What is the significance of "Temperature Recovery Time" in an audit?

A: When you open an oven door to load a sample, the temperature drops. Auditors want to know how quickly the oven returns to its setpoint. If the recovery is too slow, your product might not spend enough time at the required temperature, compromising sterilization or curing. We quantify this recovery time as part of our validation.

Q: My oven display shows 150°C, but my internal thermometer shows 148°C. Is this a failure?

A: Not necessarily. Every system has a "Tolerance" or "Acceptance Criteria." As your Quality Manager, we help you define these limits based on your process requirements. We then adjust the oven's offset to align the display with the master standard, ensuring technical accuracy.
