Shot blasting - steels and metals - Import export

At given need our experts can invoke extensive subcontracting.

Shot blasting is used for the production of metal parts subject to repetitive and cyclical stresses (landing gear, suspension parts, welding, engines, etc.). Faced with major safety constraints and problems of lightening the parts used, the interest of this technique is to be able to increase performance, slow down corrosion and increase the durability of the parts without increasing their weight. Our specialists can assist you in the development of your materials and products and in the control of industrial risks. At Mecasem, we have the latest shot blasting technologies at our disposal in order to best meet our customers' requirements. Our suspended load shot-blasting machine allows us to obtain a more varied range of impacts and opens up new perspectives for use.

The process is performed in closed chambers, where a jet of millions of glass microbeads, moving in a stream of compressed air, is directed on the product surface using a specialized gun. The abrasive removes all contaminants from the surface without changing the part geometry or damaging the product. It allows even fragile materials to be handled gently with this method. Controlled plastic deformation of the metal surface forms a light work-hardening that improves the service performance of the product. Due to the matting effect, this method is often used for finishing aluminum parts.

Continuous blasting – Excellent, highly automated processing The selected blasting medium is directed towards your workpieces at high speed using blast wheels. This ensures high blasting performance and optimum use of energy. Using this technology in a continuous process offers several advantages over batch processing: — Continuous workpiece feeding — Easy to integrate into production processes — Simplified parts flow That is why our continuous belt blasting units are frequently used to replace conventional batch systems. With their easy workpiece handling and excellent blasting results, they are even used as replacements for suspended-line systems.

Blasting is a structure-generating process for matt or satin-gloss surface structures. Small surface imperfections in the material can be concealed by the abrasive effect of stainless steel balls, which hit the material with the help of air pressure.

Due to the different thermal tempering, steel shot blasting abrasives type WIWOX® SK obtain different hardness classes from 40 – 43 HRC, 54 – 60 HRC up to greater than 61 HRC. Because of the different degrees of hardness, the steel shot in the operating mixture keeps its angular shape or becomes round during the application process.

Due to its extreme hardness, WIWOX® SG high-carbon cast steel abrasive reaches an extremely high blasting intensity right from the start. It is produced in a melting process and gets its round shape through the subsequent atomising process. The metallic structure of this low-carbon cast steel abrasive is decisive for its long service life.
