Garima Global supplies components for a wide variety of on road, off road, industrial and stationary applications such as: automotive light duty and light commercial, trucks heavy duty, tractors agricultural, earthmoving and construction machinery, generators, irrigation pumps, and defence special purpose vehicles.
Once the basic design principles and layout geometry have been decided on for a particular engine s cylinder head, designers have a limited, but complex, set of permutations and combinations to achieve the right compromise between the various conflicting demands placed on the head. These include block style inline vs.V, valves per cylinder, thermodynamics, complexity of valve train technology and of course, most importantly, the manufacturing process which directly impacts the cost.
The head also has to incorporate various ports to allow for circulation of coolant and lubricating oil, both of which have to be supplied generously to the components moving inside the head while keeping their pressure drop to a minimum.
Cylinder heads are principally made from cast iron and aluminium alloys using manufacturing processes like sand casting, die casting, lost-foam process and pressure die casting process. Mould and die design have to be undertaken with utmost care due to complexity of design of modern heads, a plethora of cavities, ports and channels that have to be cast into the head and the challenges of inspecting them during QC process. Considering the staggering complexity in design and manufacturing of cylinder heads, Garima Global has built relationships with leading manufacturers of cylinder heads in India to source heads for its global customers.
