Gravity Casting Wrought Iron Part

Our company specializes in Gravity Casting Wrought Iron Part for customers who need both aesthetic appeal and mechanical reliability. By pouring molten iron under gravity into chemically bonded sand molds, we achieve a dense, pore-free structure that machines beautifully and accepts powder-coating or hot-dip galvanizing without pinholes. From 50-piece prototypes to 20,000-piece annual programs, this Gravity Casting Wrought Iron Part delivers consistent dimensions, superior surface finish and cost-effective batch pricing for fence post caps, gate hinges, lamp brackets and vintage furniture legs.

Gravity Casting Wrought Iron Part

Key Features

Gravity-fed sand molds eliminate turbulence and gas entrapment
Wall thickness from 3 mm to 50 mm in a single pour
Cast-in logos, date codes or part numbers at no extra cost
Compatible with CNC machining, threading, drilling and tapping
Shot-blasting, e-coat, powder-coat or liquid paint ready

Product Advantages

Compared to traditional green-sand casting, our Gravity Casting Wrought Iron Part shows 30 % higher tensile strength and 20 % better elongation, allowing you to downsize sections without sacrificing safety factors. Near-net-shape geometry reduces machining stock by 35 %, cutting cycle time and tool wear. Dimensional repeatability of ±0.25 mm CT8 keeps automated assembly lines running smoothly.

Customer Benefits

≥ 400 MPa tensile strength lowers field failure rates
Reduced machining stock saves 15 % on freight per container
Cast-in threaded bosses eliminate welding and secondary operations
Classic wrought-iron texture adds premium value to ornamental products
