Manufacturing Process Paper passed through resin bath & impregnated with phenol
formaldehyde resin to obtain resin impregnated paper. These are used as Core Paper., while the top papers are Design Paper. Design Paper passed through resin bath & similarly Impregnated
through melamine formaldehyde resin. 4 Kraft Paper and 1 Design Paper arranged to form 1 Laminate. These sheets of paper are then laminated in the hydraulic press
applying pressure and heat to make a laminated sheet and during theprocess in hydraulic press, the resin passed through the pores of paperand acts as a binder between the said paper sheets.
The dry sheet is cut into the desired size and shape. The regular size ofthe laminates is 8x4 inches.
After that the inspection is done and finally it is sent for packaging.

Total Cycle Time: 565 min per cycle of 256 units (Approx).
Lot Size for Workstation 3: 256 Units
Total Value Added time for a unit: 47 min 23 sec = 48 min(approx)
Total Cycle time: 10 hrs 22 min Max Idle time for a unit at Workstation 3: 9 hrs 33 min (approx) Company using 2 production lines ahead of this Workstation 3, which
reduces Cycle Time to 5 hrs 31 min. D
Drastic reduction in the idle time before workstation 3 to 4 hrs 45min.
Similar approach is followed after workstation 3, to reducing theamount of idle time.

Optimal Reorder Point & Quantity Reorder Point:
Design Paper : D * L = 98000 * 2= 196,000 units.
Kraft Paper: D * L = 98000 * 4 * 3 = 1,176,000 units.
Lead time is considered for Imported Materials as it
constitutes 80% of Raw Materials. Reorder Quantity:
For Design Paper: Sqrt(2*D*S/H) =Sqrt(2*98000*(98000*10)/(270000)
= 843.449 units For Kraft Paper: Sqrt(2*D*S/H) =
Sqrt(2*98000*4*(98000*8*4)/(98000*4)
= 2504.396 units
