Most other dunes are made with silica sand . Break away the sand mold and remove the casting. D printing saves up to 75% in sand casting costs. Gravity casting Sand casting Low pressure casting Products.
Comprehensive mold design is another aspect of our service offering. 针对这方面的知识我们应该了解到的是优先采用砂型 精密铸造。 What we should know about this knowledge is the priority of sand casting. Therefore, the design of the gating system must be different from the sand casting. 钢、铁和大多数有色合金铸件都可用砂型 铸造方法获得。 Steel, iron and most non-ferrous alloy castings can be obtained by sand casting. The sand casting molds for multi-purpose timber production, known as the wooden model. The precision casting plant has long been engaged in sand gravity casting and metal type. (1) Castings produced by metal type have higher mechanical properties than sand castings. Casting process can be divided into sand mold casting process and special casting process. The precision casting plant has long been engaged in sand gravity casting and metal type. (1) Castings produced by metal type have higher mechanical properties than sand castings. Sand casting to sand as the main modeling material, making the traditional mold casting process.您如何看待未来10年砂型 铸造和轻金属铸造行业的发展?? How do you view the development in sand mould and light metal cast in the next 10 years? 术语“砂型 铸造”,也可以指通过砂型 铸造方法生产的目的。 The term“sand casting” may also refer to an object produced via the sand casting process. 为了提高铸件的表面质量,常在砂型 和型芯表面刷一层涂料。 In order to improve the surface quality of castings, we often brush a layer of paint in the sand and core surface. 当湿型不能满足其要求时再考虑使用粘土砂表干砂型、干砂型或是其它砂型 。 When the wet type can not meet the requirements, consider using clay sand, dry sand mold or other sand molds. 因为这样能够更好地更快地得出一些有用的东西,所以都会使用砂型 铸造方法的。 Because it can be better and faster to come up with some useful things, so people adopt sand casting method. (2)铸件的精度和表面光洁度高于砂型 铸件,质量和尺寸稳定; (2) The accuracy and surface finish of castings are higher than those of sand castings, and the quality and size of castings are stable. 底座和盖有时称为铸件,因为它们通常由铸造工艺制成,通常是砂型 铸造技术。 The base and cover are sometimes called“castings,” because they are made by a casting process, usually through sand casting techniques. 又因为砂的整体性质软而多孔,所以砂型 铸造的铸件尺寸精度较低,表面也较粗糙。 And because the overall nature of sand is soft Porous, so sand casting castings have lower dimensional accuracy and rougher surfaces. 与此同时,砂型 3D打印机越来越多地被铸造厂引用,为重型设备和机械零件制造砂芯模具。 Meanwhile, sand 3D printers are increasingly put into service in foundries to make sand cores and moulds for parts in heavy equipment and machinery. 熔模铸件尺度精度较高,通常可达CT4-6(砂型 精细锻造为CT10~13,压铸为CT5~7),WEB. Investment castings have high dimensional accuracy, generally up to CT4~6(sand casting is CT10~13, die casting is CT5~7). 位於什罗普郡(Shropshire)的铸件公司Grainger&Worrall已投资逾英镑500,000,购买S-PrintHHS3D砂型 打印机。 Shropshire castings company, Grainger& Worrall, has invested over £500,000 in an S-Print HHS 3D sand printer. 目前,国际上,在全部铸件生产中,60~70%的铸件是用砂型 生产的,而且其中70%左右是用粘土砂型 生产的。 At present, internationally, in all casting production, 60 to 70% of castings are produced in sand , and about 70% of them are produced using clay sand . 我们开发的新功能和新技术旨在不断完善砂型 铸造工艺,从而节约成本、能源和材料。 New features and technologies we develop are designed to continuously perfect the sand casting process, delivering cost, energy and materials savings that add up. 我国或是国际上,在全部铸件产量中,60~70%的铸件是用砂型 生产的,而且其中70%左右是用粘土砂型 生产的。 Internationally, in all casting production, 60 to 70% of castings are produced in sand , and about 70% of them are produced using clay sand .
