Cores are used within grey iron castings to form the internal geometry of parts or undercut areas that cannot be moulded. Core making facilities at Chamberlin & Hill include:

A total of
automated shell machines

A total of
cold-box machines

The machines are used to manufacture the cores in both low and high-volume applications. The range and scale of core making facilities at Chamberlin & Hill allow the versatility to ensure the right core technology is used to meet a products quality and cost requirements.


The shell core making process lends itself to producing intricate, delicate cores where dimensional control and surface finish are critical. These characteristics make it ideal for smaller grey iron components with complex internal geometry such as turbocharging or hydraulic applications.


The cold box core making process provides a fast and cost-effective method of producing cores with even sand distribution and compaction in a wide array of applications. Suited to the production of larger cores, or to be paired with shell cores in non-critical areas to reduce cost, they are valuable technology used widely for the manufacture of grey iron castings for commercial vehicle components and general engineering applications.


As the leading UK Cast Iron foundry, we have been manufacturing castings on site for over 125 years. During that time we have produced castings for a variety of different markets in many countries.
