At VSPL, quality control checks are conducted throughoutthe Laminationmanufacturing process, at half-hour intervals, on every machine, and the recordsare maintained separately.
The Laminations are checked for Edge Burrs, Width, Camber, Thickness, Stack Thickness, Wave Factor, etc., which have to be in accordance with the respective least measurements done by various measuring devices.

Standard Tolerance on various parameters is as follows:

Sr. No.	Characteristics	Acceptance Limit/Criteria
1	Width (mm)	0 to 100 (+/- 0.15) 100 to 130 (+/- 0.20) 230 to 380 (+/- 0.25) 380 to 580 (+/- 0.40) 580 and above (+/- 0.50)
2	Thickness (mm)	+ 0.03 mm
3	Edge Burrs (micron) Thickness - mm Up to .23 .27 to .30 .35	Burrs Micron 10 15 20
4	Length (mm)	Upto 350 (+0.00/-0.30) 350 to 1000 (+0.00/-0.60) 1000 to 2000 (+0.00/-1.00) 2000 and above (+0.00/-2.00)
5	Edge Camber	For material with a width greater than 150mm, edge camber shall not exceed 0.80mm for a length 1.5 Meter
6	Wave Factor (i.e, Deviation from flatness)	For material with a width greater than 150mm, the deviation from flatness expressed as a percentage shall not exceed 1.5%
7	Angle	+/- 5 Minutes
8	Stack Thickness of Individual stack except center step	+1-0mm

Although we follow IS Standards, however our plant works at the most upgraded technology with far ahead stricter quality norms than above mentioned standards to ensure the best of customer's needs.
