            Casting Parts



            Aluminum Foundry

            When "sand casting" the second half of the first type

            on the plate,put sand box filled sand compaction Calibrating

            made under type finish, made a good sand will be rotated

            180 degrees, put a halfsize, sprinkle parting agent,

            put the sand box, fill and compaction of sand, Calibrating

            the sand box will be rotated 180 degrees,respectively,

            to remove the upper and lower mold halves,

            then flipped 180 degrees on the type and the lower Hao,

            sand making finished, waiting for pouring.

            This process, commonly known - "foundry."





            Carbon Steel Casting Gear Parts

            1.according to use can be divided into the carbon steel,

            carbon structural steel ,carbon tool steel and free cutting

            steel three, steel structure is divided into engineering

            construction steel and machinery manufacturing steel two;

            2.by refining methods can be divided into open hearth steel,

             converter steel;

            3.according to the deoxidation methods can be divided

            into boiling steel (F), steel (Z),semi killed steel (b) and

            special steel (TZ);

            4.according to the carbon content of the steel can be

            divided into low carbon steel(WC ≤ 0.25%), carbon

            steel (WC0.25% - 0.6%) and high carbon steel (WC>0.6%)

            5.according to the quality of the steel can be divided into

            ordinary carbon steel(carbon steel containing phosphorus,

            sulfur, carbon steel (high quality),

            low phosphorus sulfur) and high-grade steel

            (phosphorus, sulfur less) and super high quality steel. Description:

            the higher the hardness greater carbon content of

            general carbon steel,strength is high, but low plasticity.


            SUS Casting Parts

            Sandblasting is powered by compressed air,

            to form a high-speed jet beam will spray

            material (copper sand, quartz sand, silicon carbide, iron ore, sand)

            high-speed jet to the surface to be treated,

            so that the surface appearance or shape changes.

            Due to impact and abrasive cutting action on the work

            piece surface, the surface of the work piece

            to obtain a roughness of different cleanliness,

            the mechanical properties of the surface is improved,

            thereby improving the fatigue resistance of the work piece,

            and the coating increases its adhesion between the coating

            extends the durability,

            but also conducive to peace and decorative paint flow.





            Foundry Casting

            Foundry casting sand with clay bonded molding

            materials for the production of castings, is the

            historic process method is the most widely used

            process method. Speaking of a long history,

            dating back thousands of years ago; On its scope

            of application, you can say that no one around

            the world do not have.




            Cast Iron Frame

            Cast iron is easy to cast shape complex parts;

            cheaper; internal friction of cast iron, and have a

            good vibration resistance. The disadvantage

            is the long production cycle, higher unit production

            costs; casting easy to produce waste, quality is

            difficult to control; casting allowance big,

            big machining costs. Common gray cast iron,

            there are two: HT200 suitable shape is simple,

            the unit pressure greater (p> 5 kg / cm 2) of the rail,

            a large bending stress or (σ ≥ 300 kg / cm 2) and

            other bed ; HT150's liquidity is good,

            but somewhat less mechanical properties

            suitable for complex shapes and load small base.

            If the wear resistance of gray cast iron can not meet the

            requirements, should be cast iron.
