Aluminum Shock Absorber Housing Casting for Automotive Suspension
汽车减震器壳体
A356-T6 gravity cast shock absorber housing for OEM automotive suspension programs, CNC-machined on bore and mount faces by an IATF 16949 supplier in Ningbo.
Product Overview
This A356-T6 shock absorber housing is gravity cast for automotive suspension systems where fatigue life, bore concentricity, and mounting point accuracy directly affect ride quality and safety.
Bohua manufactures shock absorber and strut housings for passenger car and light truck OEM programs from our Ningbo facility.
Gravity casting is selected over die casting for this part type because the T6 heat treatment delivers the elongation and fatigue resistance that suspension load cycles demand.
CNC machining is applied to bore IDs, upper mount faces, and bracket interfaces per customer GD&T.
As an IATF 16949 certified supplier with 20+ years of automotive casting experience, we handle tooling, sample validation, SPC reporting, and export logistics.
