manufacturing are becoming increasingly important [1]. In Europe the use of cement and concrete (a mixture of cement, aggregates, sand and water) in large civic works can be traced back to antiquity. In 2008 there were 268 installations producing cement clinker and finished cement in the European Union with a total of 377 kilns [4].

Sand casting, while nowhere near as precise as investment casting, is a low-cost, low complexity manufacturing process that has repeatedly proven itself as an integral part of modern manufacturing. If investment casting is too cumbersome, or if large parts are needed, consider implementing sand casting into your production line.

Precast concrete elements produced in plants using modern techniques and machineries. Raw materials such as concrete, sand, and reinforcement bars are under high level of quality control. Formworks used are of higher quality than those used at construction sites. This allows truer shapes and better finishes in precast components.
