Investment Castings of Mechanical Parts

Investment Castings of Mechanical Parts, also widely known as lost-wax precision castings, are core industrial components manufactured by professional silica sol investment casting technology. Adopting advanced lost-wax molding and high-temperature shell firing process, these castings perfectly integrate precise dimension control, exquisite surface quality and stable mechanical performance. They can realize one-piece forming of complex-shaped mechanical parts that are difficult to complete by traditional casting and machining processes, greatly reducing subsequent processing procedures and production costs.

We support a full range of customizable material options, including carbon steel, alloy steel, stainless steel, ductile iron and special alloy steel such as 16Mn, 10# steel, 4140 QT and QT340HV. All raw materials strictly comply with international ASTM, DIN, BS and Chinese GB standards, with complete material certification and test reports available, ensuring high strength, good wear resistance, corrosion resistance and impact resistance of the castings under long-term working conditions.

With standardized production processes from wax pattern injection, shell making, dewaxing, high-temperature pouring, heat treatment to finishing, our products feature high dimensional accuracy, smooth surface without sand holes and air holes, stable structure and no deformation. The precision tolerance can reach CT grade and meet GB/T 1804-m standard. It is suitable for mass production and small-batch customized prototype production, realizing near-net shape forming and saving raw material and processing cost for customers.

These precision investment cast mechanical parts are widely applied in construction machinery, agricultural machinery, forklift accessories, automobile and truck spare parts, petroleum machinery, railway locomotive components, ship accessories, food machinery and engineering hardware industries. They are ideal for manufacturing structural parts, connecting parts, transmission parts, impellers, shell parts and other key mechanical components.

We provide one-stop OEM & ODM customized service, supporting production according to customers’ drawings, samples or technical requirements. Strict quality inspection is implemented in every production procedure, with professional dimensional inspection, mechanical property testing and appearance quality control. All products pass SGS and ISO standard quality system certification, with stable delivery cycle and perfect after-sales technical support, providing reliable long-term precision casting solutions for global industrial equipment manufacturers.
