Grey iron contains flake graphite and is excellent for vibration damping, while ductile iron features spherical graphite, offering significantly higher strength, toughness, and plasticity, making it ideal for high-pressure valve applications.
Yes, we specialize in OEM services. We can manufacture parts according to your specific drawings using a variety of crafts including resin sand, lost-wax, and lost-foam casting.
Our CNC precision machining capabilities allow us to produce metal and plastic parts ranging from as small as 1mm up to 300mm in diameter/length.
The best method depends on the required tolerance and quantity. Generally, sand casting is cost-effective for large volumes, while lost foam or vacuum moulding is preferred for more complex geometries and tighter tolerances.
Yes, we offer a full suite of secondary processing including surface grinding, CNC engraving, and complete sub-assembly work after the initial production is completed.
In addition to various cast irons, we work with aluminum, alloy steel, stainless steel, brass, and a variety of plastics such as nylon, PMMA, and teflon.
