Decarfish precision casting 2-1 Features and advantages
(1) The maximum limit of the casting is 700mm, and the length of the easy -to -make is below 200mm. The maximum weight of the casting is about 100 kg, which is usually less than 10 kg.
(2) The size of the casting is 20mm+013mm100mm+0.30mm200mm+0.43mm, while the size accuracy of small parts is not easy to reach+0.10mm. The angle tolerance is+0.5+20 degrees, the minimum thickness of the casting is 051.5mm casting surface thickness RMAX4S12S
(3) There are no restrictions on casting materials, such as aluminum alloy, magnesium alloy, titanium alloy, copper alloy, various steel, cobalt -based and nickel -based heat -resistant alloys, and hard materials.
(4) Make complex shapes of workpieces, with good size accuracy and less cutting processing. (5) Save materials waste and can be produced in large quantities. Affairs machines, and other machine parts.
