Our static casting foundry and foundry expert have more than 30 years of production experience, we is focusing on the castings for heat treatment furnace components, our heat resistant casting for heat treatment fixtures are casted by investment casting , namely lost wax casting, and sand casting methods. Main products includes casting stackable baskets for heat treatment furnaces, trays and grids for furnace, roller hearth trays , serpentines trays , furnace fixtures, jigs, for chamber furnace, pit furnaces. Our company work with german companies for long term cooperation, most of our castings are exported to germany, france, italy, spain, usa, south america, turkey, sa and get very good reputation from our valued customer, more products like fan wheel, skid riders, link belt casting, loading bars, cross beams, walking beams. (cast furnace fans, grids, and baskets, high alloy heat resistant casting base tray and basket)

What is a heat exchanger?
It is used to warm or cool a product by exchanging heat between the process fluid and a service fluid,which is typically water, ice water, glycol or steam. The hot or cold service fluid flows around the tubes within the tubular heat exchanger and heat is transferred between the product and the media.
