Overview ning Valve Casting

1. Nanu ing casting

Ing likidu a metal mibubu ya keng mold cavity a maki hugis a makayagpang keng bage, at kaybat nang me-solidify, metung a bage a maki hugis, sukad ampo kalidad ning babo ing makwa, a awsan dang casting. Atlung maragul a sangkap: alloy, modeling, pouring ampo solidification. Ing pekamaragul a advantage: malyari lang gawan deng komplikadung bage.

2. Panyulung ning pamag-cast

Ing produksyun megumpisa ya kanitang 1930s gamit ing pneumatic machines ampo artificial clay sand processes.

ing cement sand type linwal ya inyang 1933

Inyang 1944, ing cold hard coated resin sand shell type linwal ya

CO2 hardened water glass sand mold linwal ya inyang 1947

Inyang 1955, ing thermal coating resin sand shell type linwal ya

Inyang 1958, linwal ya ing furan resin no-bake sand mold

Inyang 1967, linwal ya ing cement flow sand mold

Inyang 1968, linwal ya ing water glass a maki organic hardener

keng milabas a 50 banua, bayung paralan ning pamaglalang casting molds kapamilatan ning pisikal a paralan, antimo reng: magnetic pellet molding, vacuum sealing molding method, lost foam molding, atbp. Miyayaliwang paralan ning pamag-cast base kareng metal molds. Antimo ing centrifugal casting, high pressure casting, low pressure casting, liquid extrusion, atbp.

3. Features ning casting

A. Malawak a pamagbayu at pamagbayu. Egana ganang metal a produktu. Ing pamag-cast ali ya limitadu keng timbang, sukad ampo porma ning bage. Ing timbang malyari yang manibat mapilan a gramu anggang dinalan a tonelada, ing kapal ning pader malyari yang manibat 0.3mm anggang 1m, at ing porma malyari yang maging masyadung komplikadung bage.

B. keraklan kareng raw ampo auxiliary a materyales a gagamitan da malawak la at mura la, antimo reng scrap steel ampo balas.

C. Deng casting malyari lang magpasanting keng dimensional accuracy ampo keng surface quality da reng casting kapamilatan ning advanced casting technology, para deng bage malyari lang maputol mas ditak ampo alang pamagputol.
