Bauma 2016 fair were holded in Shanghai, China and end on Nov 25th,2016. Over 3000 companies from demestic and overseas and over 170000 professional visitors attended this fair. Precision received more than 50 customers visit during the four days and well expressed our products and image as a leading manufacturer of precision machining parts. We showed automotive parts,hydraulic parts, agriculture parts ect.on this fair. 

But regardless of the method that is used, aluminum sand casting should result in a mold cavity being formed. These air set molds can be formed using a casting flask that has both a bottom and a top part.Next, the sand mixture is pressed together around the pattern of the mold cavity. The final part of the assembly will often require the sand to be vibrated in order to eliminate any holes or empty spaces in the mold. The casting liquid is ultimately what is poured into the mold cavity, and once the metal has cooled off and become solid, the casting can be finally divided from the sa......

Casting process is pouring the required smelt material liquid into the mold, then cooling the solidification, cleaning to get the required casting parts. Advantage and disadvantage of casting processMost casting parts are lowcost, especially the complex shapes casting parts with complex cavity, and with wide adaptability and good mechanical properties.But the casting material, such as metal, wood, fuel, modeling materials, etc, and the casting equipment, such as metal furnace, mixer, molding machine, core making machine, shakeout machine, shot blasting machine, etc, will genera......

Hardness Comparison Table-Drop Forging-Investment Casting-Steel Casting Hardness Test Process and Table We could use the Normalizing, Tempering, Annealing to reach the hardness our customer required. I attached the hardness comparison Table for customers to check the hardness.  Our main products are investment casting, lost wax casting, forging, large forging, mold forging, machining, steel casting, aluminum casting, etc. All our parts could be OK to reach the hardness required! ......

Drop Forging Manufacturer ProcessOur Forging machine press the metal blank to obtain the forging shape with required mechanical properties. Our forging presser is 560KG Air hammer, 750KG Air Hammer, 1T Air Hammer, 5T Air hammer, 2500T forging presser, etc Advantage of forging partsCompared with the same material casting process, forging process could eliminate the metal casting porosity, mechanical welding holes. So the forging parts are with much better mechanical properties than casting parts. The important parts with heavyload or applied in the rigorous condition, are produc......

Investment Casting provides dimensional accuracy and fine "presentable" casting surface than traditional casting.  Investment casting is also called "Lost  wax casting".  It involves the following 5 steps.     1. Mold Making: Make a mold to inject wax into.     2. WAX Pattern Forming:  Inject molten wax into a mold, then assemble formed wax patterns on a wax tree.     3. Wax Surface Coating: The wax needs to be strengthened  by a covering it in a solid shell. This is done by dipping the wax tre......
