Pattern making

Sand casting

Whether cast iron, cast steel or aluminium: in order to cast a casting in a sand mould, a positive pattern is always required.
These are often wooden patterns. For large patterns and/or one-off pieces, polystyrene (foam) is commonly used. If durability is important, for example, a pattern can also be made in wear-resistant resin or aluminium.

For this we work together with experienced pattern shops.
If you already have an existing pattern, we can also supply castings based on your patterns.

Precision casting

Precision casting requires metal (negative) tooling (similar to an injection mould) into which liquid wax is injected. These wax pieces have the shape of the desired casting, and are assembled in "trees" to make a ceramic mould into which the pieces are cast.

Precision casting is used for steel and stainless steel, best suited for smaller pieces in medium to large series. Main advantages are the high dimensional accuracy (as a result of which finishing can be reduced or redundant), good surface quality, and the possibility of (locally) thin-walled casting.
