Sand Plant:

Two automatic sand plants for different moulding lines, consisting of two Sand Mullers of capacity 30 MT/hr. each (Make: Fonk -Taiwan) and two Sand Mixers of capacity 50 MT/hr. & 64 MT/ hr. (Make: DISA) are operational. There are also two rotary & vibrating sand coolers with world class De-Dusting system. The SMC (Sand Multi Controller) system helps total control of sand parameters, with SCADA automation. The sand plant is also equipped with Sand Drying System (5 MT/hr.) and larger Pneumatic Conveying System (6 MT/hr.) to convey the material in the correct time.
Advantage: Automatic systems can produce & control very consistent quality of sand property, which helps to reduce mould & casting quality variation, as a result the customer gets better quality castings with consistent wall thickness.

Cold Box Core System:

Equipped with an Automatic Laempe Cold Box Core Shooting Centre of 40 litre, 10 litre and 5 litre capacity and a Laempe mixture of capacity 4.2 MT.
