WHAT SERVICE WE OFFER?
We offer you OEM service for casting parts , especially in sand casting.
Sand casting,also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process.Sand casting is relatively cheap and sufficiently refractory even for steel foundry use. In addition to the sand,a suitable bonding agent is mixed or occurs with the sand. The mixture is moistened with water to develop strength and plasticity of the clay and to make the aggregate suitable for molding.The sand is typically contained in asystem of frames or mold boxes known a flask. The mold cavities and gate system are created by compacting the sand around models, or patterns, and or carved directly into the sand. Can maintains typical tolerance accuracy within CT12-CT14 standard, with a surface finish of Ra50-100.
CAN WE OFFER CNC CATING PARTS?
Yes, We offer CNC service to make the surface of casting parts as polished & precise as you request.
WHAT KIND OF SURFACE TREATMENT CAN WE GET?
Heat Treatment, shot blasting, sand blasting, machining, polishing, plating, powder coating, anodizing, zinc plated(galvanization,), oxide, etc.
HOW WE MAKE THE PARTS COMPLY TO CUSTOMER'S REQUIREMENT?
Useing our coordinate measuring machine, tensile testing machine, spectrograph and other testing equipments to make all the goods qulified.
HOW CAN WE QUOTE FOR YOU?
As our factory only supply OEM service, Please send us enquiry by email, with all the technical drawings youhave, with all of your requirements, such as material grade, tolerance, machining demands, surface treatment,heat treatment, mechanical property requirements, etc. Our specialized engineer will check and quote for you, we would appreciate the opportunity and will respond in 3~5 working days or less.
