Standard/custom cylinders, made to drawing
Custom manufacturing by drawing is a dedicated service by Shiguang Xingyao for customers needing non-standard parts. Customers provide drawings, samples or detailed technical parameters, and we arrange specialized domestic factories for custom production. The product range covers machined parts, sheet-metal parts, welded structures, castings/forgings and heat-treated parts.
Import-substitution parts for imported equipment, repair and remanufacturing of old-equipment parts, design and machining of non-standard parts for special conditions, custom parts for equipment upgrades and small-batch trial parts.
Flexible lead time, with urgent orders delivered in 7-15 days; prices 50-80% lower than original imported parts; single-piece orders supported with no MOQ; traceable quality with material and inspection reports.
