Sand casting is a casting process which can be used in manufacturing. It makes use of a pattern and a sand mixture. The pattern is pressed into the sand mixture and a mould is created by pouring molten metal into the cavity left behind.
This is quite a simple method of production and can be suitable for a number of industries and applications. Some of the products made using this process might include machine tool bases, cylinder heads, pump housings, valves and engine blocks. It’s also relatively cheap so will provide a cost-effective production method.
There are three main types of sand casting patterns which are made use of regularly: loose patterns, cope and drag patterns, and matchplates. The type of pattern will depend on the type of manufacturing. Sand casting is often a process used for low-volume production, though it can cover higher volumes of product if automated equipment is used. It is often used in conjunction with other processes such a 3D printing. Benefits can include cost reductions and accuracy.
