Introduction of High-precision Ceramic Press Welding Characteristics

Mar 28, 2018

In the process of producing high-precision Ceramic Press Welding, we believe that high-precision ceramic molds are important production elements. Under normal circumstances, the use of high-precision textile ceramic mold casting can produce a variety of casting products with complex shapes and patterns on the surface.


The manufacturing materials used in high-precision Ceramic Press Welding

generally belong to alloy materials such as various die steels, stainless steels, alloy cast irons, and zinc alloys, copper alloys, and aluminum alloys. In comparison, the ceramic mold complex mold can save more than 40% of the cost, and the mold cavity is generally no longer cutting processing, the service life is often close to or exceed the mechanical processing mold.


At present, there are two kinds of casting methods that are mainly used in the production of high-precision Ceramic Press Welding. One is that the entire casting mold is filled with a ceramic-type slurry. This method is usually a small-size mold suitable for single-piece and small-batch production. The other is that the working surface layer of the cavity is made of ceramic slurry to ensure that the mold reaches the required dimensional accuracy and surface roughness. The backing part is made of sand or metal sleeves to save the expensive fused alumina. Powder and ethyl silicate raw materials reduce production costs. This type of mold is usually used for mass production of large and medium-sized molds.


Combined with the actual process flow, the high-precision ceramic press welding process includes: model preparation sand mold modeling grouting mold removal spraying drying boxing pouring cleaning heat treatment. Zinc alloy molds are often used in many varieties and batch productions, such as injection molds, blow molds, blanking molds, drawing molds, and the like.


In addition to these features, high-precision ceramic press welding has a good simulation forming performance. Compared with other similar processing methods, the production cycle of high-precision textile ceramic molds can be effectively shortened, which saves costs.
