What materials are used in precision casting?
In precision casting,we can use stainless steel,carbon steel,alloy steel,etc.,which can be used for precision casting.Nevertheless specific,still want to undertake choosing by specific circumstance.
Xi 'an Haosen Precision Casting Co., LTD
In order to enrich the workers'life,activate the company's cultural atmosphere,and cultivate the workers'spirit of unity and struggle,the company's trade union held a table tennis relay competition in the morning meeting on May 24th.
Precision casting technical requirements
For example,sand mold precision casting,mass production of the factory should create conditions to adopt advanced technology modeling,core making method.The production line of the old shock type or shock type molding machine is not high enough,the labor intensity of workers is big,the noise is big,do not adapt to the requirements of mass production,should be gradually transformed.
The use of casting materials
Since its appearance,the casting material Baozhu sand has been widely concerned by the casting industry,widely used in resin sand(furan resin,phenolic resin),sodium silicate sand(organic fat,CO2 hardening),coated sand.Suitable for all kinds of casting methods such as:V method,VRH,lost not only can greatly improve the quality of castings,easy and deoxidization,with sand process easy and convenient(local with sand sheet small batch,the large cast steel plant)with little or no artificial mixing with sand,can save the most casting coating,especially suitable for producing high quality castings.Good fluidity and filling,good formability and casting strength.
What exactly is an instrument?
Instrumentation is used to detect,measure,observe,calculate various physical quantities,material components,physical parameters and other instruments or equipment.Pressure gauge,measuring instrument,microscope,multiplier are all instruments.In a broad sense,instruments can also have automatic control,alarm,signal transmission and data processing and other functions,such as pneumatic and electric regulating instruments used in the automatic control of industrial production process,as well as distributed instrument control system are also instruments.
Analysis of development trend and prospect of foundry industry
Talent shortage.In the process of the development of China's casting technology,what is most lacking is not technology,but talents.The main reasons for the brain drain are the low salary and poor working environment of domestic casting enterprises.
2.Small enterprise scale.Many foundry enterprises,small scale.There are many working foundry enterprises,and many of them are small in scale and relatively backward in technological level,resulting in low labor productivity,low product quality,and sometimes safety accidents and vicious competition.These problems hinder the development of enterprises
Xi 'an Haosen Precision Casting Co., LTD. Tool procurement tender notice
Xi'an Haosen precision casting Co.,Ltd.is now the company's tool procurement open bidding,welcome good reputation,in line with the bidding requirements of enterprises to participate in the bidding.
Causes and preventive measures of surface pitting of precision casting
The condition of complete deoxidization is:choose dry and clean charge,add ferro manganese first after melting,then add ferrosilicon deoxidization,then add calcium silicon deoxidization,then stop power for 2min,then add aluminum final deoxidization after insulation casting.Immediately after pouring,add wood chips or waste wax to recover the box for sealing and cooling.
What testing equipment is needed for foundry laboratories?
Lab need furnace in foundry industry or furnace hot metal silicon carbon analysis before the molten iron carbon si-mn analyzer,furnace top five elemental analyzer(chemical analysis),five elements analyzer is commonly known as,actually many elements can be analyzed and five element analyzer
Precision casting is also called investment casting
Sand casting production of precision castings,surface finish,the density of material and microstructure and mechanical properties are often poor,so when casting these performance requirements higher,other casting method should be used,such as casting,lost wax casting
