We offer integrated services, from demand integration to end-to-end support. Based on specific customer requirements (such as material, precision, batch size, cost, and performance), we customize the most suitable “process + material + service” combination, combining technical feasibility and economic efficiency, ultimately achieving high-quality and efficient delivery of castings.

Design Collaboration Solutions: We participate in the customer’s product design phase and use CAE simulation (such as casting flow and temperature field analysis) to optimize casting structure (e.g., adding process feeding and avoiding sharp corners) and reduce late-stage production defects.

Supply Chain Integration Solutions: We provide one-stop services from raw material procurement (custom alloy smelting), casting production, heat treatment, machining, and final assembly, streamlining customer supply chain management.

Quality Traceability Solutions: Establish a full-process data recording system (raw material batches, process parameters, and test reports), enabling full lifecycle traceability of castings through blockchain or information systems to meet compliance requirements in industries such as aviation and medical.

We provide tailored casting solutions tailored to the specific operating conditions of different industries (such as high temperature, high pressure, corrosion resistance, and high precision):

Aerospace: Solutions for high-temperature resistant alloy castings (such as nickel- and cobalt-based alloys) meet the high strength and creep resistance requirements of components such as engine blades and casings. Vacuum melting combined with precision investment casting ensures low porosity and uniform microstructure.

Automotive: Solutions for lightweight aluminum alloy and cast iron castings, including engine blocks, transmission housings, and chassis components, utilize processes such as high-pressure die casting and sand casting to achieve a balance between high productivity and cost, while optimizing the structure to reduce fuel consumption.

Medical Devices: Titanium alloy and stainless steel precision casting solutions. For surgical blade holders and implants (such as artificial joints), we utilize zero-wax investment casting combined with surface passivation to ensure biocompatibility and dimensional accuracy (tolerances up to ±0.02mm).

Energy & Power: Heat-resistant steel castings for thermal/nuclear power plants (such as turbine blades and valves) combine water glass sand casting with aging heat treatment to enhance high-temperature oxidation resistance and fatigue strength. Ductile iron wheel hub solutions for wind turbines enhance toughness through austempering.

Engineering Machinery: Wear-resistant cast iron and low-alloy high-strength steel casting solutions. For vulnerable parts such as excavator bucket teeth and crane gears, we utilize lost foam casting combined with surface hardening to improve wear resistance and service life.

Based on the complexity, precision requirements, and production batch size of the casting, we select the appropriate casting process and optimize the process:

Investment Casting Solutions: For castings with complex cavities, thin walls (minimum wall thickness 0.5mm), and high precision (tolerances IT7-IT9), we offer full-process technologies such as wax pattern 3D printing, multi-layer shell coating (zircon sand + silica sol), and vacuum casting. These technologies are suitable for small batches of precision parts (such as aircraft engine nozzles).

Sand Casting Solutions: For medium-to-large castings (up to several tons) and medium precision requirements, we offer optimized molding sand formulations such as resin sand and water glass sand. Combined with vacuum molding and vibration compaction processes, we reduce production costs and are suitable for mass production (such as machine tool beds).

Die Casting Solutions: For thin-walled parts made of low-melting-point metals such as aluminum alloys and zinc alloys (such as mobile phone midframes and motor housings), we offer high-pressure die casting mold flow channel design and vacuum-assisted die casting (VAD) technology to reduce porosity and improve surface quality, making them suitable for large-scale production.

Centrifugal Casting Solutions: For tubular and cylindrical castings (such as steel pipes and bearing sleeves), this solution uses centrifugal force to evenly distribute the molten metal and optimize wall thickness consistency. It is suitable for rotating parts requiring high density.

Vacuum Casting Solutions: For easily oxidized metals (such as titanium and magnesium alloys) or for castings requiring a porosity-free design, this solution provides an integrated melting and pouring process under a full vacuum environment to prevent gas inclusions and improve mechanical properties.

Targeted technical solutions are provided for common defects or performance deficiencies in casting production:

Defect Repair Solutions: We use argon arc welding, laser cladding, and other technologies to repair defects such as porosity, shrinkage, and cracks in castings. Repair results are verified using non-destructive testing (UT/MT) to reduce scrap rates.

Performance Enhancement Solutions: We optimize casting mechanical properties (strength, hardness, and toughness) through heat treatment processes (such as solution aging and carburizing). We also enhance corrosion or wear resistance through surface treatments (electroplating, spraying, and anodizing).

Cost Optimization Solutions: For mass-produced castings, overall costs can be reduced while ensuring quality through process simplification (e.g., near-net-shape production to reduce machining), material substitution (e.g., replacing steel with aluminum alloy to reduce weight and cost), and mold life extension (e.g., surface nitriding).

Rapid Prototyping Solutions: For small-batch trial production during the new product development phase, rapid casting technologies such as 3D-printed wax/sand molds and low-pressure casting can be used to shorten the design-to-prototype cycle to as little as one-third of that of traditional processes.
