Kòm yon manifakti chenn asye won depi 30 an, faktori nou an te rete ak epi sèvi peryòd enpòtan evolisyon endistri fabrikasyon chenn Chinwa a, ki satisfè bezwen min (min chabon an patikilye), leve bagay lou, ak transpò endistriyèl pou chenn asye won ki gen gwo rezistans. Nou pa rete sèlman kòm pi gwo manifakti chenn asye won nan Lachin (ak yon ekipman anyèl ki depase 10,000T), men nou kontinye kreye ak inovasyon.
