Sinthani Mwamakonda Anu ndi Zojambula Zanu
Pazojambula zojambulazo, dipatimenti yaukadaulo idzayang'ana mosamala zojambulazo ndikuwonetsetsa ngati kulekerera kwajambula kuli koyenera komanso ngati ukadaulo wathu ndi zida zomwe zilipo zitha kukwaniritsidwa. Malo, kukula, font ya mtundu wa foundry ndi yoyenera kwa mankhwalawa panthawi ya galasi lamadzi.
Pazofunikira za Material and Mechanical properties, titha kuthandiza monga pansipa:
1.Kaya zomwe zili pachithunzichi zidzakwaniritsa zofunikira zamakina? Pali mitundu yosiyanasiyana yamakina pazinthu zilizonse.
2.Kodi malo omwe mankhwalawa amagwiritsidwa ntchito ndi ati? Malo ogwirira ntchito osiyanasiyana, monga kutentha kwakukulu, kutentha kochepa, chinyezi chambiri. Tikupatsirani chithandizo chosiyana koma choyenera chapamtunda kuti mufotokozere.
3.Kodi tingatani pamene zofunikira zamakina sizisintha ndipo sizingasinthidwe? Ndife odziwa kusintha zinthu zamakina azinthu kuti tikweze zida zamakina ndikutha kusinthira zinthuzo kwa inu.

Sinthani Mwamakonda Anu ndi Zitsanzo Zanu
Zitsanzozi zidzakhala ndi mayesero angapo ndikuwunika pambuyo polandira.
1.Dimension muyeso
2.Chemical composition test
3. Mayeso a katundu wamakina
4. Jambulani zojambula zoyambira ndi kulolerana molingana ndi zomwe zili pamwambazi ndi deta, kuti mutsimikizire ndikutsimikizirani.

Gawo Lachitsanzo
1.Ngati pakufunika, potengera kuponya, mainjiniya athandizira kupereka malingaliro osinthika osinthika amiyeso yosakhala yovuta kuti akwaniritse zabwino kwambiri. Zoonadi, zosinthazi sizidzakhudza kugwiritsidwa ntchito kwenikweni kapena kusonkhana.
2.Pakupanga kuponya opanda kanthu, nthawi zonse timayesetsa kuti ndalama zogulira zikhale zochepa, kuchepetsa kulemera kopanda kanthu kuti zikuthandizeni kuwongolera mtengo.
3.Pakati pakupanga, tidzachita zomwe tingachite kuti tikuthandizeni kuthetsa mavuto.
