Stainless steel Catamold lines
Sampling system for Stainless steel ceramic powders Catamold lines NDC Infrared Engineering has developed an in-line sampling system for moisture measurements in closed processes. The PowderVision sampling system, which is suitable for use with ceramics powders, allows moisture to be measured in powders, granules and flakes flowing in enclosed ducts or gravity fed conveying systems. Designed to work with an NDC 710e NIR Moisture or Multi-component Gauge, PowderVision collects samples every few seconds, with measurement values output via digital or analogue connectivity to a PLC or SCADA system for process control. PowderVision consists of a tube-mounted sampling cup made from 316 stainless steel which slides into a collar that is permanently welded into the appropriate duct in the process. It is optically coupled to the 710e NIR gauge via a sapphire window. The cup collects sample as it flows through the duct, allowing moisture and other
measurements to be made simultaneously. When the measurement is complete, the cup is emptied using a jet of compressed air and the next sampling sequence begins. Making continual on-line moisture measurements eliminates the need to send samples away for laboratory measurement and allows drying processes to be controlled automatically, helping users to achieve consistent product quality, as well as creating opportunity for increased product yield and reduced fossil fuel consumption through process optimisation. User-configurable software in the 710e HMI provides control of the PowderVision’s sampling timing sequences according to the required sample collection rate, and the gauge’s measurements are automatically synchronised with the filling and emptying cycle. The gauge reading is then held until the sampling process has been repeated.

BASF has developed Catamold 17-4PH K and Catamold 316L K for MIM. Catamold is a ready-to-use raw material for metal and ceramic injection moulding (MIM and CIM). The wide product range includes low-alloy and stainless steels, special alloys, and ceramics, and the two new materials are stainless steel variants. BASF says that it has also improved efficiency in the production process. “We’re passing on this economy of scale to our customers,” said Dr Matthias Pfeiffer, responsible for global business management for Catamold. “Thanks to the lower feedstock costs, our customers
will be able to exploit new markets and be more competitive in the face of competing technologies.” The new products are available internationally and technical support is offered in all. This follows news in December 2012 that BASF is to build a new Catamold plant in Kuanyin, Taiwan, in the second half of 2013.The company has also built an application technology lab for Catamold in Shanghai, China. “These investments reflect our commitment to driving growth in the metal injection moulding industry,” said Dr Stefan Koser, vice president metal systems at BASF.
Whisker-reinforced ceramic grades improve toughness Ssangyong Materials Corp has launched SW400 and SW800 silicon carbide (SiC) whiskerreinforced ceramic grades. Aluminium oxide has been used successfully as a cutting tool material for many years in high speed machining, mainly due to its excellent hardness and chemical stability at high temperatures. However, the application of aluminium oxide can be limited in interrupted cutting of high nickel based alloys at high cutting speed because of its low resistance to fracture. The SW400 and SW800 ultra-strong whiskers reportedly improve fracture toughness and notch wear resistance in the machining of super-alloys at high speed cutting.
The ceramic grades are made from silicon carbide.
SW400 and SW800 also have high productivity and extended reliability in the machining of nickel and cobalt-based alloys, as well as Inconel, Stellite, HSS and so on. They have excellent wear and thermal shock resistance at high surface speed. Ssangyong Materials Corp also offers coated whisker ceramic inserts for increased performance.
