The application for cast iron are expansive and
we produce small one off architectural or replica castings for items such as
motorbikes or historic bridges. We also
operate a separate track for larger scale production giving us economies of
scale to ensure we offer competitive lead times and prices. Operating at up to 1000kg and all in sand casting covering
all the common derivatives such as Ductile SG, Grey Iron, Malleable, High
Chrome, Ni Hard, Ni Resist and Pearlitic.

Die casting with accuracy
If you want high volume castings with a high level of dimensional accuracy in aluminium or zinc then our Pressure Die casting plant is the answer.
High Dimensional Accuracy
If you require parts with a high dimensional accuracy but perhaps not the volume to consider die casting, then shell moulding provides an ideal solution.
Shell Core Products
Quality castings, in house
Being self-sufficient provides complete control over the quality of your castings so production of cores is always carried out in house.
Sand Casting & Pattern Production
Globally recognised for our skill

Gravity Die Casting & Tooling
Dedicated die casting zone
Our casting design consultants will work with you on your products to design a die that will deliver results time after time and is as cost effective as possible.
Engineering and Finishing
For a uniform surface finish
After careful fettling all our castings have the option of being put through our Sisson Lehmann shot blasting machine.
Completely Machined Castings
To provide a complete one stop engineering solution we can provide completely machined castings using our Haas CNC machining centres.
In gloss or matt finishes.
Our power coating facility allows us to supply castings painted uniformly, after shot balsting and etching.
Rumbling & Polishing
De-burr and shine!
Castings that may need to be handled are part of assembly or form part of a decorative item can be rumbled to de-burr the surfaces.
Heat Treatment, HiP & Impregnation
Make me stronger!
We perform heat treatment in a highly controlled environment to ensure that the casting retains its original shape without cracking.
Castings accurately finished
Simple conventional machining operations are also easily performed by our skilled machinists, to provide an accurate finishing to your castings.
