    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.
