Import Aluminum Investment Casting — Buy in wholesale FOB from Supplier in China

Qinhuangdao AnYe Metal Industry Co., Ltd. produces aluminum investment castings using A356-T6 alloy via the silica sol (water glass replacement) shell process, with facilities on Qiantangjiang Road in Qinhuangdao, Hebei Province. The T6 heat treatment, comprising solution treatment followed by artificial aging, is standard for this alloy to achieve specified mechanical properties. A356 is an Al-Si-Mg alloy with 6.5 to 7.5 percent silicon and 0.25 to 0.45 percent magnesium, offering excellent castability and corrosion resistance. The supplier also maintains gravity die casting and pressure die casting capabilities, providing process selection based on part geometry and volume requirements.

The silica sol investment casting process produces near-net-shape components with surface roughness typically Ra 3.2 to 6.3 micrometres, superior to sand casting but coarser than ceramic shell investment casting using ethyl silicate binders. The shell build-up involves multiple dips in silica sol slurry with refractory stucco, with drying between coats. Critical process controls include shell thickness uniformity, dewaxing autoclave parameters to prevent shell cracking, and molten metal pouring temperature. The supplier lists CNC machining centers, turning machines, milling machines, and lathes for post-cast finishing, plus mirror and electrolytic polishing capabilities for cosmetic or fluid-dynamic surfaces.

End-use sectors cited include aerospace, military, automotive, and electronic equipment, where investment casting permits complex internal geometries that would be impossible with machined billet or forged alternatives. Typical aerospace applications include bracketry, valve bodies, and sensor housings subject to moderate stress and tight dimensional requirements. Buyers should confirm whether the supplier holds NADCAP accreditation for aerospace work, or IATF 16949 for automotive, as these are not stated. The machining equipment count suggests medium-scale operation, though actual spindle utilization and shift patterns would indicate true capacity. First article inspection reports, including radiographic or CT scan data for internal soundness, should be requested for critical applications.

Qinhuangdao AnYe Metal Industry Co., Ltd. operates from an address on Qiantangjiang Road in Qinhuangdao, a port city in Hebei Province on China's northeast coast, approximately infinite300 km east of Beijing. The company's name appears in variant forms in source materials (Qinhuang Dao AnYe Metal Pars. Inc. versus Qinhuangdao AnYe Metal Industry Co., Ltd.), suggesting possible translation differences or historical naming changes. The trust tier is harbor, with zero recorded response rate and zero average response hours, indicating limited or unmeasured digital engagement rather than verified trading history. No founding year, employee count, or annual turnover is disclosed.

The supplier's equipment inventory includes 10 CNC machining centers, 8 CNC turning machines, 15 CNC milling machines, and 20 CNC lathes, suggesting a machining-heavy operation relative to foundry floor area. The capability to perform mirror polishing and electrolytic polishing in-house indicates vertical integration for cosmetic-critical parts. However, the listing does not state foundry capacity in tonnes per year, number of wax pattern injection machines, shell making capacity, or melt furnace specifications. Buyers should verify whether the supplier is a foundry with machining, or a machining house with foundry subcontracting. Quality system certification (ISO 9001, AS9100 for aerospace, or IATF 16949 for automotive) should be requested and validated for current status.
