QINGDAO DONGHAILIN FOUNDRY MACHINERY CO.,LTD.

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.

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.

All required protective coatings are made in certified external companies. The basic condition for cooperation is meeting all environmental requirements. Our capabilities include the following metal protective coatings: - aluminum anodizing (soft and hard); - cataphoresis (electrophoretic painting); - electropolishing; - galvanic zinc; - hot-dip galvanized (galvanizing metal); - powder coating. As a production company, we offer: - metal sandblasting of crude steel; - removing paint coatings by sandblasting and soda blasting (without heating and damaging the surface); - glass blasting of stainless steel and aluminum; - unifying the surface after machining and welding; - large-area painting with a hydrodynamic, airless unit.
