Shrinkage growong ora bisa dihindari ing casting. Nalika logam kelangan lan solidifies, volume bakal nyilikake, lan shrinkage.
Apa kita kudu ngatasi iku kanggo nggawe growong shrinkage dumadi ing bagean sing ora impact ing kualitas casting.
Nalika nggawe jamur, nyetel riser ing posisi ngendi volume logam gedhe lan kira-kira rongga shrinkage bakal kelakon, supaya growong shrinkage bisa kui ing riser. Iki minangka prinsip dhasar, sing gumantung saka wangun casting.
Casting shrinkage growong amarga casting solidifies ing cara lapisan dening lapisan solidification, lan Cairan lan solidification shrinkage luwih saka shrinkage ngalangi, mbentuk bolongan gedhe lan klempakan ing bagean solidification pungkasan casting. Solidification urutan, Kajaba saka riser lan wesi kadhemen, lan desain cukup struktur casting kanggo nyegah casting shrinkage.
