Kunyangwe iyo chaiyo yekukanda ine zvirema zvekukanda, senge shrinkage cavity, trachoma, fractal surface, gomba rekudira;Forgingspane rimwe divi.

Iwe unogona zvakare kudonhedza chigadzirwa pasi, uye teerera kune ruzha rwekuparara, kazhinji ruzha rwekukanda muffled,kuumbakunzwika kuderera!

A castingichidimbu chakagadzirwa nekukanda, umo mold kana modhi inodirwa nesimbi yakanyungudutswa. Iyo nzira iyo iyo simbi inonyungudutswa kuita mvura inosangana nezvimwe zvinodiwa uye inodururwa muforoma yekukanda, uye ipapo kukanda (chikamu kana chisina) chine chimiro chakafanotemerwa, saizi uye kuita kunowanikwa mushure mekutonhodza uye kusimba.

A forgingchidimbu chakagadzirwanenzira yekugadzira. Aforgingchidimbu chakagadzirwa nesimba rekuita.Forginginzira yekugadzira neimwe mechanical properties, maumbirwo uye saizi nekuisa pressure pamabhiliti esimbi kuti abudise mapurasitiki deformation.
