In the past 24 months, Grainger & Worrall of Bridgnorth has carded out 11 separate diesel engine cylinder block
development programmes for leading European and North American automotive OEMs.
The remaining 40 percent of content, including cylinder blocks
and heads, is made in-house.
These castings include 34,500 cylinder blocks
and 5800 cylinder heads and several other components for 55 different automotive, truck and engine manufacturers, along with 72 industry suppliers (mostly machining companies) and research institutes.
The CGI cylinder blocks
would be produced at Tupy's Joinville foundry using the SinterCast process control technology, the company said.
Brazilian cast iron cylinder block
and head metalcasting group Tupy has received an order for a new high volume compacted graphite iron (CGI) passenger vehicle cylinder block
, to be produced at its North American base in Sakillo, Mexico.
This procedure is mirrored on the cylinder block
line where, again, a MecWash Midi is used for the initial wash with, this time, a Maxi installed for the final cleaning of the block and combined bedplate.
PurePower Technologies LLC, a Navistar company, recently started production of compacted graphite iron (CGI) cylinder blocks
at its Indianapolis casting facility.
The hydraulic pump and motor are 80% interchangeable, with identical pistons (nine in each unit), cylinder blocks
, housings and valving.
Rolls Royce cylinder blocks
and heads are aluminium coatings which, because of their relative softness, are prone to damage when deburring.
