As key fittings designed for water and wastewater systems, municipal piping, building plumbing and other critical applications, our premium cast iron fittings are produced by sand casting from molten cast iron.

Coated (shell) sand is used, consisting of quartz sand, pre-coated with thermoplastic phenolic resin and a hardener - hexamethylenetetramine. The metal model plate is heated to 180–340 °C.  

Rocker arms made of high quality cast iron for automobile engines. Made from high-strength cast iron grades QT450/QT500 with CNC-machined working surfaces. The foundry is ISO 9001 and IATF 16949 certified. High fatigue strength and wear resistance. Export worldwide from Qingdao, China.

Agricultural machinery operates in harsh field conditions with high loads, where the reliability of spare parts directly determines uptime and harvesting efficiency.

Our sand cast hanger clamp is a durable, specialized line fitting designed for overhead power lines, substation busbar systems and new energy grid connections.

In industrial hydraulic systems, key components of pumps and valves are critical factors that determine the pressure load capacity, tightness and service life of the entire equipment.
