Olw’okutandika okulwawo, entandikwa entono n’ensengeka y’amakolero etali ya magezi ey’amakolero g’amakolero aga fitting agakolebwa nga tegannabaawo mu China. okuva mu nnongoosereza n’okuggulawo, wadde ng’amakolero g’okukola ebitundu eby’enjawulo agakoleddwa nga tebinnabaawo gakulaakulanye mangu, ekituli kikyali kyeyoleka bw’ogeraageranya n’amawanga agakola mmotoka. naddala bw’ogeraageranya n’amakampuni agakola ebitundu eby’ebweru, ekituli kisinga kweyoleka{{2}
In addition to the gap in scale, the gap between China's prefabricated spiral parts manufacturing industry is more important than manufacturing technology and management technology. According to relevant information, there are more than 5,000 non-state-owned accessory enterprises with state-owned, state-controlled and sales income of over 5 million yuan, and the total number of small-scale village enterprises, small non-state-owned enterprises and family workshops will exceed 7,000-8,000. More than 80% of sales are below 100 million yuan, and only 130 are over 100 million yuan. Nearly 70% of the domestic component suppliers have high production costs and low overall efficiency, which is relatively or significantly lacking international power. Bosch prefabricated spiral accessories company's sales revenue in 2008 reached 47 billion Euros, wadde nga China esinga obunene mu kutunda ssente za Spiral Accessories ezikola nga tezinnabaawo buli mwaka teziwera kawumbi ka ddoola za Amerika (enyingiza ya Wanxiang Group eya 2009 mu kutunda yali ya bukadde 51,480), ekituli kino kyeyoleka nnyo.
