- Uku{0}}Modular biyan diyya na matsa lamba (sauyi ƙasa da ko daidai da 2N)
- Matsi{0}}algorithm ɗin sarrafa haɗin kai na yanzu
- Nazarin Case: Wani sabon aikace-aikacen shari'ar baturi mai ƙarfi ya inganta daidaitaccen ƙarfin walda daga ± 30% zuwa ± 3%.
V. Tsarukan Tabbatar da Ingancin Hankali
1.Tsarin Kula da Yanar Gizo
- Kulawar juriya mai ƙarfi (daidaita ± 0.1mΩ)
- Ganewar fashewar ƙura (yawan ganowa kashi 99.9%)
- Nasarar: Kamfanin kera sassan chassis na kera ya rage ƙimar walda ta karya daga 1.2% zuwa 0.005%.
2.Tsarin Babban Dandalin Bayanai
- Gina bayanan bayanai mai ɗauke da sigogin walda 2000+:
- Shawarar tsarin AI (digiri 98% daidai)
- Tsarin bincike na kai{0} (95%)
- Aiki: Mai kera kayan masarufi ya gajarta sabbin zagayowar haɓaka samfur da kashi 70%.

Kammalawa: Tsallewar Fasaha a cikin walda ta Galvanized
Ta hanyar daidaitawa na mitar inverter 1000Hz da tsarin sarrafawa na hankali,MFDC tabo waldasun yi nasarar magance ƙalubale guda uku na duniya a cikin walda na ƙarfe na galvanized: lalata Layer zinc, zafi ya shafi faɗaɗa yanki, da matsalolin daidaita ma'auni. Tabbatarwa a cikin masana'antu 38 ya nuna cewa wannan fasaha yana rage ƙimar farashin walda don abubuwan haɗin gwal da kashi 45% kuma yana haɓaka haɓakar samarwa da kashi 180%. Kamfanonin da suka fara aikin fasahar waldawa ta MFDC suna samun fa'idodi biyu masu fa'ida a cikin haɓaka inganci da haɓaka farashi.
