Foundries today face the challenge of managing a transformation process that requires new, and in some cases, complex geometries. At the same time, the focus is on marginal costs and the efficient operation of a core shop. For more than forty years, Laempe Mössner Sinto GmbH (LMS) has been the world market leader for core shooters in the foundry industry and covers all areas of modern core production with its comprehensive product and service portfolio. The German company is a complete solution developer with its headquarters in Meitzendorf. Approximatley 400 people are employed at the headquarters and the branches in Schopfheim and Mannheim, and at the subsidiaries in Pune (India) and Beijing (China).
Core shooters ‘Made in Germany’: complete in-house production at Meitzendorf
LMS designs and builds core shooting machines, core sand mixing and distribution systems, automation units and 3D-sand printing machines for all available core sand binder processes in various versions. The wide range of machines offer solutions for all types of use, whether small series with high demand on tool changes for the classical jobbing foundry with light and simple tooling or high speed machines for heavy and complicated tooling for serial production e.g. in the automotive industry. Shooting volume starts at one litre for small cores or lab applications up to 1,700 litres for serial production. For all cold-hardening gas-curing processes, LMS offers the suitable gassing technology and for heat-curing process best fitting heating options. LMS has integrated nearly all manufacturing steps from raw materials to ready machines in-house. The core competences of Laempe also include innovative automation solutions. In addition to the traditional construction of core shooters, Laempe specially developed a 3D printing technology for core production (additive manufacturing).
Efficient solutions for every application
Laempe machines are easy to maintain, and all core shooter type LFB machines are characterised by fast cycle times, high availability, reliability and a long service life. Thanks to the optimal use of machine components, energy consumption is low and thus Laempe machines and systems are energy-efficient in operation. In the field of sand preparation LMS offers well proven vertical mixers with capacities between 2 and 15 tons per hour. The mixer can be completed with sand sifters for dedusting, heating and/or cooling the sand. Such systems help to reduce scattering of mixing results due to ambient temperature variations. Highly accurate dosing systems for liquid and powder components deliver best mixing results. The high mixing intensity combined with the precise dosing of binders and additives in a narrow temperature range of the raw sand offers foundries a homogeneous quality with low addition of materials. This is an important part of becoming effective, both economically and environmentally.
Partner network, spare parts and new technologies: for maximum machine availability
Specialists at LMS and at the company’s worldwide network of partners support customers in all aspects around the core shop, might it be about the binder systems or the tooling design. The overall target is always the best product at the lowest possible costs.
Laempe has vast know-how in the field of maintenance and repair of core shooters and plants. In combination with a large spare parts warehouse and technical hotlines, LMS is able to help every customer at any time in machine operation.
