Product Name: Custom-Made Stainless Steel Checking Valve Body Certification: CE, RoHS, ISO 9001:2008 Standard: ASTM Machining Tolerance: +/-0.01mm Surface Roughness: Ra0.8 Surface Preparation: Sand Blast Material: Alloy Steel Application: Machinery Parts Molding Technics: Gravity Casting Process: Investment Casting Casting Method: Thermal Gravity Casting Deliver Time: 25-35 Days Trademark: ODM Transport Package: Bubble Bag, Carton, Pallets or Wooden Box Specification: OEM Origin: China Product Description Two types of investment cast processes:Silica Solprocess and the water glass process. The Silica Solprocess is used to cast complex high quality parts with requirements of a very good surface finish and close dimensional tolerances.This processcan range from a weight of just a few ounces to approximately 80 pounds. If you are concerned with precision in very small parts, we are especially proficient at very fine detail work including teeth and serrations. The water glass process is typical of the process in the early stages of investment castings. It generally is capable of much larger castings than theSilica Sol process, but does not have as good of surface finish or tolerances.The water glass process provides parts that have better surface finish and dimensional tolerances than sand castings. This process may range in weight from several ounces to approximately 200 pounds.We have the capacity to provide OEM, ODM service.We can provide casting, machining, heat treatment, surface treatment service according to your drawings, ideas or samples.MaterialProduction processProduction equipmentProductsOur service:1.20yearsofmanufacturingsuccessinChinaandexportingexperienceworldwide2.Globalspecializedproducerofmachinedcastings.3.Wecombineourownresourceswithsomeotherwell-developedfactoriestofulfillawiderangeofcontractmanufacturingcapabilities.Workingwithonesource,savestimeandmoney.4.Satisfiedsupplierof7bigcompaniesfromNorthAmericaandEurope.5.Lowcostmoldmaterialsandfocusonefficiencyofferacost effectivesolutiontoyourmetalcomponentpurchasingrequirements.6.Normalleadtimesrangefrom1to6weeksforfully-machinedcomponents.7.Strongcapacitytohelpcustomersdevelopnewprojects.8.Oursalesdepartmentis24hoursavailableinordertohelpourcustomerssolveproblemsquickly.FAQ:1.
