Precision casting - Lost-wax castings

Production processes

CMR Group also supplies sand castings up to 200 kg in weight in alloyed steel or stainless steel. Thanks to precision casting smelting technology, there are no limitations as to minimum lot quantities.

Stainless steel lobe pump housing

Growing demands from the market to reduce the cost of mechanical machining of sand-cast steel parts encouraged CMR Group to develop and expand their use of precision casting (or “lost-wax” casting) technology.

We produce stainless steel precision castings

The production facilities for these products are situated in the Far East for various reasons, among which:

Know-how, tried-and-tested production processes, modern machinery and the best leading-edge technologies plus qualified, expert personnel enable CMR Group to speed up and optimize the initial stages of the projects.

Main sectors

Other sectors: agricultural, flue industry.

Precision casting technology can be used to produce parts of very different sizes and weights, from just a few grams to as much as 30 kg.

Low cost precision casting moulds means that limited production lots can also be supplied, thus with low impact in terms of mould depreciation.

Precision casting technology produces parts very similar to finished products, even when their shapes are extremely complicated.

This technique also does away with problems concerning casting drafts and undercuts, which usually occur when sand casting techniques are used.

Very high-quality surface finishes can be obtained thanks to the use of the most advanced precision casting technologies, including the creation of logos and trademarks with excellent definition.

A vast range of materials can be used for precision casting: alloyed steel, stainless steel, aluminium, bronze and other alloys of various types enable parts for the most varied applications to be produced: from components for agricultural machinery and earth moving machines, to parts for the ship-building, food, mechanical, furniture industries and machinery components.

Based on the Customers’ drawings, CMR Group can supply both “blanks” and already machined parts using conventional machine tools and machining centers (CNC), also with mirror-polished or satin-finish surfaces.

CMR Group‘s industrialization department works together with the Customer to design, develop and produce precision-cast parts to replace those originally made by metal-working methods, often achieving cost reductions and obtaining aesthetically more attractive components.
