Ningbo Daxie Development Zonam Tianshan Cylinder Clausus Co., LTD. (infra postea ut "Tianshan Cylinder Clausus") anno 1992 condita est, cum capitis descripserunt 5 decies centena milia Yuan, in Ningbo, Provincia Zhejiang, adiacentem ad centrum translationis internationalis Beilun Portus.
Tianshan cylinder block adheres to the technology orientation as the core, sets product research and development and application services in one, and gradually realizes the leap from traditional manufacturing to advanced manufacturing. At present, Tianshan cylinder sleeve covers an area of 24,000 square meters, with advanced machinery and equipment of more than 200 sets, and is a professional KZY (Φ57.3/58) motorcycle durabilis cylindri accessiones suppliers and KZY (Φ57.3/58) motorcycle durabilis cylindri accessiones factory. The company has always focused on technology, deep cultivation, forging ahead, strong technical force, advanced manufacturing technology, and continues to scale, with science and technology advancing.
Sicut praelata electio clientium, Tianshan cylindri obstructio producta cum "technologia provecta, technologia bona, qualitas plena, varietas" nota in mercatis domesticis et externis, et per totam terram vendidit, et in Asiam Australem et alias regiones et regiones exportavit, nunc plus quam 300 varias species exemplaris habet.
