Gray iron contains flake graphite and is excellent for vibration damping, while ductile (nodular) iron contains spherical graphite, offering much higher strength, toughness, and plasticity.
For highly complex geometries, we recommend lost-wax or vacuum moulding. For larger industrial parts with specific tolerances, lost-foam or resin sand casting are often most efficient.
Yes, we provide precision machining for aluminum, alloy steel, stainless steel, brass, and various plastics such as nylon, PMMA, and teflon.
Our CNC precision machining services can produce parts ranging from 1mm to 300mm, depending on the material and complexity of the design.
Yes, after the CNC prototyping or production is completed, we can handle all secondary processing and sub-assembly work to provide a ready-to-use product.
With over 16 years of specialized experience in hydrant and valve bodies, we use rigorous material quality control and improved production crafts to ensure superior surface finish and durability.
