Drilling deep holes up to 4mA deep hole is classified on the basis of a depth-to-diameter ratio of at least 10: 1 (with a minimum diameter of 10mm). Deep hole drilling is used in many industrial applications, but its origin comes from the need to drill very accurate and straight barrels, where the depth-to-diameter ratio can exceed 20: 1 (with a maximum diameter of 150mm and a length of up to 4000mm).
Screw segments of laboratory twin screw extrudersThe process of co-rotating twin screw extrusion is widely used in research and production processes. Multiple operations, including solids transfer, melting, pressure build-up, degassing and shaping, can be performed simultaneously in one process. The segmented auger elements may be configured to meet the processing requirements of multiple recipes using the same set of auger segments. However, this kind of unlimited flexibility is only meaningful if the geometry and operating conditions used to enter the formula are properly selected. How to optimize the choice of screw geometry and processing conditions?
New vulcanization linesThe innovative furnaces that are the subject of the offer enable the vulcanization of rubber in the field of infrared radiation - this ensures an effective process in terms of cross-linking time, product quality and process costs. ZAMAK MERCATOR has developed new lines for vulcanization of rubber and silicone, including: IR blast furnace and IR tunnel furnaces. Tunnel furnaces enable the vulcanization process to be carried out with the use of infrared heaters and can be used for the production of profiles of very different shapes. A key feature of these devices is the ability to control the atmosphere inside the furnace. During operation, the furnace can be filled with an inert gas, e.g. nitrogen (N2), thanks to which the influence of atmospheric oxygen on the vulcanized product is reduced to a minimum.
Zamak Mercator 2022 calendarLadies and Gentlemen, 2021 was undoubtedly the year that will go down in the pages of our history. The ongoing COVID19 coronavirus pandemic was not conducive to the stable development of many companies in our industry, both on the Polish and foreign market, and newer and newer sanitary restrictions and recommendations made it difficult to nurture interpersonal and business relationships.
