Import Aluminum Deep Drawing Sleeves — Buy in wholesale FOB from Supplier in China

Aluminum deep drawing sleeves from Zhejiang Invitech Precision Technology Co., Ltd are precision-engineered cylindrical components used in metal forming operations, specifically designed for multi-station transfer molding systems. The source specifies material as Aluminum Alloy 6061-T6 or 7075-T6, both heat-treatable wrought alloys with documented mechanical properties. These sleeves function as draw dies, blank holders, and container rings in progressive and transfer press operations where aluminum's strength-to-weight advantage reduces tooling mass and improves press dynamics compared to steel counterparts.

The 6061-T6 temper offers typical yield strength of 276 MPa with excellent corrosion resistance and weldability, suitable for general industrial drawing applications. The 7075-T6 temper provides significantly higher typical yield strength of 503 MPa with lower density, preferred for aerospace structural forming where every kilogram of tooling mass affects cycle economics. Both alloys in T6 condition achieve their properties through solution heat treatment and artificial aging per AMS 2770 or equivalent; verify that Invitech's heat treatment lot certification includes actual tensile test results rather than nominal values. Surface finish and dimensional tolerances for bore concentricity, outer diameter, and wall thickness variation are critical for draw sleeve performance but are not quantified in the source.

Primary buyers span automotive body panel stamping, aerospace structural component forming, and precision consumer goods manufacturing. The sleeves reduce die set weight for faster press stroking and lower energy consumption. When sourcing from Zhejiang Invitech, confirm whether the quoted specification includes rough-machined or finish-machined condition, as deep drawing sleeves often require final grinding or honing to achieve the precise bore-to-OD concentricity demanded by multi-station tooling. The supplier's location in Deqing Economic Development Zone, Huzhou, places it within Zhejiang Province's advanced manufacturing corridor with established CNC machining and heat treatment infrastructure.

Zhejiang Invitech Precision Technology Co., Ltd is located at No. 916 Fengqing Road, Deqing Economic Development Zone, Huzhou City, Zhejiang Province, China, postal code 313200. Deqing sits within the Yangtze River Delta manufacturing region, providing access to precision machining subcontractors, heat treatment services, and aluminium alloy distributors. The supplier holds a harbor trust tier, though its response rate is recorded at 0.00 percent with zero average response hours, indicating no documented buyer communication history on the platform.

The company positions itself as a precision technology manufacturer with capability in aluminium deep drawing sleeves for demanding sectors including automotive and aerospace. No founding date, employee count, factory floor area, revenue figures, or specific quality certifications are stated in the available profile. The mention of custom grades, sizes, and surface treatments suggests in-house engineering and CNC machining capability. Buyers should verify current ISO 9001, AS9100, or IATF 16949 certification status directly, as these are standard expectations for aerospace and automotive supply but are not confirmed in the source material.
