We are capable of mixing and producing an infinite number of polyurethane compounds, and offer some of the most advanced manufacturing capabilities available, including custom molding and machining.
1.Cutting is going to take the part that we needed to make a machine from a whole stainless steel plate.
2.Circle barrels:The steel plate to make a round pot body.
3.Welding is a fabrication process that joins materials, usually metals, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal. In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that is usually stronger than the base material. This steps will give a promise of machines’sealing
4.Grinding in order to gain ground surface level off is smooth.At this time there were very fine grinding surface and uniform grinding crack.Polishing is divided into two kinds of coarse grinding and fine grinding.
4.1. The coarse grinding Coarse grinding is to amend the rough surface and irregular shape forming.
4.2. Fine grinding After coarse grinding of metal surface are now deep grinding crack, need to eliminate in the fine grinding, prepare the way for polishing.
5.Testing pressure:This step in order to test the resistance of boiler pressure,Steam heating boiler must have good compression capability
6.The surface of the polishing process is to get the light like a mirror machining process. Normally polishing wheel is used to polish on the surface of parts after repeatedly tiny uneven, will be used in coating surface modification.
Mirror polishing is the last process of coating surface or surface of machine, its purpose is to eliminate grinding crack that still remained on the surface after polishing process.Ideal polished surface should be smooth, shiny, perfect and day relief, pit, metal disrupt the layer as the state of the mirror surface.After grinding and polishing of mill.
