Specialists from SKB-3 KMZ presented an innovative technology for the production of a propeller shaft bracket for a special purpose boat. The boat has a length of 49 meters, a width of 9 meters, and a draft of 2.6 meters. On board there is a superstructure with a wheelhouse, as well as living and technical premises.
The propeller shaft bracket is a large steel part, during the production of which there is a risk of defects, such as burn-on. (Formation of local overheating and adhesion of molten metal to the walls of the casting mold).
To prevent such problems, the SKB-3 team developed a unique slotted gating system. It allows to weaken the flow of metal during pouring, which protects the casting mold from overheating.
Thanks to this innovation, it was possible to manufacture castings without a single defect. All parts were successfully shipped to the customer on time. KMZ continues to develop its technologies, which allows the company to remain competitive in the market.
