We supply high precision gray iron turbocharger bearing housing castings produced by resin coated sand casting process. This turbo intermediate housing is the core supporting component of turbocharger, connecting turbine wheel and compressor wheel, with built-in oil passage for lubrication and cooling. It features good thermal conductivity, vibration damping performance and stable mechanical property under high temperature working conditions. Our turbo shell castings are widely matched with diesel engines for heavy trucks, construction machinery, generator sets and marine power equipment. We support OEM and ODM custom production according to customer drawings, samples and technical specifications. We can customize oil channel structure, flange size, mounting hole position and casting tolerance. All raw cast iron materials are strictly tested for chemical composition before melting. We strictly control casting quality to eliminate slag inclusion, porosity and shrinkage defects which are critical for turbo parts. After casting, secondary processing services including shot blasting, machining, oil hole drilling and tapping can be provided as required. Our foundry can handle small trial orders and mass bulk production with stable lead time. As a professional casting sourcing platform, we connect qualified foundries and provide overseas buyers with competitive price, full dimensional inspection report and production progress tracking. The resin sand casting process ensures smooth casting surface and high dimensional accuracy for complex internal runner structure of turbo housing. We can provide rough casting blanks or semi-finished machined parts as customers need. The turbo bearing housing must keep stable oil sealing and heat dissipation in long time high-speed operation, so each batch will be sampled for penetration test and hardness inspection. Material certificates and inspection documents can be issued on request. We accept FOB, CIF and other trade terms, and adopt anti-collision packaging to avoid damage during long sea shipping. Global engine and turbocharger purchasers are welcome to send drawings or specifications for quotation, we look forward to establishing long-term stable supply cooperation of turbo casting parts with you.
