Thickened Base Stamped Parts

Name: Thickened Base Stamped Parts
SKU: 122

Thickened Base Stamped Parts from XIAYI are CNC-turned in one clamping from solid 6061-T6 aluminum, weighing one third of steel yet holding coaxiality at 0.015 mm. As the manufacturer, we machine thickened flanges exactly where the load lands — light, precise, and rust-free by nature.

Product Description

The Thickened Base Stamped Parts kit — a conical positioning cap plus a sink cylinder support base — breaks the steel rule book: it is integrally CNC turned from solid 6061-T6 / 6063 aluminum bar, with thickened wide flanges where load concentrates. No split welding seams, one-third the weight of steel, natural corrosion resistance that outlasts any zinc coating on salted winter roads.

Structure That Solves Assembly Problems

Feature	Benefit
Automatic centering conical guide on the cap	Corrects piston rod coaxiality during press-fitting — assembly eccentricity eliminated at the root
Thickened wide flange load-bearing rims	Disperses lateral impact over a larger contact area — no flange warpage or sliding
Sealed sink cylinder buffering cavity	Fully wraps buffer rubber, blocking silt and rainwater to slow rubber aging
One-step CNC turning, no joints	No weld seams to crack, no fatigue line — and aluminum cuts unsprung mass to 1/3 of steel

Aluminum Grade Selection

Grade	Performance	Best For
6061-T6 tempered aluminum	Tensile ≥ 260 MPa, pore-free, anodized 500 h salt spray without white rust	SUV, off-road, coastal, mountain, EV chassis
6063 aluminum	Ultra-light, moderate strength, as-machined finish	Inland dry sedans, short-range EV commuters
Recycled aluminum casting	Internal pores and lamination — fractures under bump impact	Rejected — safety hazard, no assembly scenario

CNC-Grade Tolerances, Stamped-Part Simplicity

Coaxiality of matched central holes ≤ 0.015 mm — tighter than the typical 0.025 mm of stamped steel, ending piston rod eccentricity
Flange end face flatness ≤ 0.01 mm — full contact with sheet metal brackets, no local stress concentration
±0.008 mm micron tolerance on cone angle, cylinder depth and flange thickness — full interchangeability on automatic lines
Mating surface roughness Ra ≤ 1.6 μm — no tool marks or burrs to scratch buffer rubber or rod chrome coating

FAQ

Q: Why aluminum instead of zinc-plated steel?

A: Three reasons: weight (1/3 of steel reduces unsprung mass and improves handling), corrosion (native oxide layer plus anodizing outlasts zinc on salted roads — no seizure during disassembly), and precision (single-clamping CNC turning holds 0.008 mm, far beyond multi-process stamping).

Q: We ship to humid overseas markets. Will these rust in transit?

A: No — anodized aluminum kits carry stable factory surface protection that resists moisture and salt through ocean freight, protecting your review ratings and return rate.

About XIAYI aluminum sourcing: only genuine solid 6061/6063 bar is machined in-house — recycled castings with hidden pores never enter the line, because an internal void is a fracture waiting for a bump.
