Industrial Precision Valve Body: Investment Casting + 4-Axis CNC Finishing Solution

A professional industrial fluid control equipment manufacturer requires customized aluminum alloy precision valve bodies. The product has complex internal flow channel structures, requiring zero burrs in flow channels, hole position tolerance within ±0.02 mm, and assembly verticality and parallelism strictly controlled within 0.03 mm.

New Energy Vehicle Motor Housing: Die Casting + 5-Axis CNC Precision Machining Solution

A leading domestic new energy vehicle parts manufacturer requires high-performance aluminum alloy motor housing components. The key technical indicators include bearing hole coaxiality within 0.01 mm, sealing surface flatness controlled within 0.03 mm, and ultra-low roughness of Ra≤0.2 μm for key fitting surfaces.

2500T Integrated Die-Casting Solution for Mass Production of NEV Transmission Housings

For transmission products supplied to a major domestic new energy vehicle manufacturer, extremely high precision is required: flatness within 0.05 mm, positional tolerance within 0.1 mm, and aperture tolerance within 0.005 mm.

High-Precision LED Structural Components: Integrated Die Casting + CNC Solution

A large listed LED display manufacturer in China requires high product precision, especially flatness and verticality within 0.1 mm. Stringent surface salt spray resistance requirements must also be satisfied.

Frequently Asked Questions

Are you a trading company or a direct manufacturer?

We are an experienced factory with more than 20 years of expertise in casting and machining. We boast profound professional knowledge and technical capabilities in this industry. You can rest assured that we are a legitimate manufacturer—you will always see our workshops busy with actual production.

What types of manufacturing services does your company provide?

We offer a comprehensive range of die casting and gravity casting services, including mold design and manufacturing, aluminum alloy die casting, precision CNC machining, surface treatments (such as sandblasting, painting, and polishing), as well as product quality control and inspection.

Can you provide a quotation based on 3D drawings?

Certainly. We can provide a formal quotation once we receive your CAD files or editable 3D models. Please note that 2D drawings alone are not enough for the production of high-precision components.

We accept 3D CAD models from various design software, including SolidWorks (.sldprt), Pro/E (.prt), as well as universal file formats like IGES (.igs), STEP (.stp), ACIS (.sat) and Parasolid (.x_t).

Do you provide samples?

Yes, we provide samples for customers to assess the quality and performance of our products. The sample fee covers production and shipping costs and is calculated based on the order quantity and product complexity.
