RAW MATERIAL INSPECTION

PMI & ULTRA SOUND conducted on all the bars procured to confirm the grades received & detect cracks in bars stock.

RAW MATERIAL INDENTIFICATION

Color coded have been provided for all grade of alloy steel & stainless steel for Raw Material identification.

CHEMICAL ANALYSIS OF RAW MATERIAL

Chemical analysis of raw material is done randomly on each size of bars stock for 16 Components & confirms the composition as per the grade required.

SHOP FLOOR DRAWINGS & PRODUCTION PLAN

Detailed drawings for all the size are provided to shop floor to manufacture & Inspect the dimensions as per the drawings provided.
Production targets are given for each process involved to meet the delivery schedule.

MANUFACTURING PROCESS

Bars stock is cut to sizes by BANDSAWS For Bolts Bars are centered & Chamfered prior to forging.
BOLTS & NUTS are hot forged in open/Close dies.
Bolts /Nuts ate machined to required dimension & Finish.
Bolts are grinded to size on centre less grinder to obtain desired sizes.
Prior to Tapping of Nuts the blanks are finished by reamers for high Quality Threading.

HEAT TREATMENT

To achieve the required hardness, Tensile Strength & other mechanical properties.
Fasteners are heat treated by annealing, Solution annealing, hardening/Tempering
This process is sub-contracted to an ISO 9001 Heat Treatment company.

INSPECTION

Stage wise inspection of parts under production.
Random inspection of sizes in Semi – finished condition.
100% inspection by GO-NOGO gauges if requested by buyer.
Or it is conducted on 25 parts per 1000 parts.

FINISHING

The Fasteners are finished to buyer requirement such as Electro-plating, Hot Dip
Galvanizing, PTFE / XYLAN/ FLUORO CARBON Coating for Alloy Steel & Mild Steel
Fasteners (Coating Thickness is inspected)
Electro polishing & buffing for Stainless Steel Fasteners.

MARKING

Manufacturers Identification Mark ANC & the grade are clearly marked on each Fastener.

FINAL INSPECTION OF FASTENERS

Visual inspection is done for visible marks/cracks/deformities or Sharp edges. Bolts, Nuts & washers are assembled till end of threads.

PACKING

All the fasteners are packed in corrugated boxes with labels indicating Size, Qty, and Grade.
Weight of each box is below 30 Kegs for easy handling & storing. These Boxes are stuffed in wooden crates.
This is for all Export Order, for local order the packing as per purchase order terms.

DOCUMENTATION

All the Mill certificates, PMI, Ultra test, Spectro analysis, Drawings, Inspection reports are
documented for each order for traceability of Product.

CERTIFICATION

Conformity Certificate is provided by the manufacturer.
