Import Aluminum Punching Machine — Buy in wholesale FOB from Supplier in China

The Jinan Kingdear Machinery aluminum punching machine is a dedicated station for punching aluminum profiles in window and door fabrication, built around a six-station rotary turret that lets an operator switch between dies without changeover downtime. The unit runs on a three-phase 380V / 50Hz supply and is driven by a 2.2kW motor turning at the rated spindle speed. A 5MCY oil pump delivers hydraulic pressure up to 16 MPa, generating 50 kN of pressing force with a 30 mm stroke length and a cycle rate of 30 punches per minute. The closed die height is 185 mm, and the overall footprint measures 900 mm by 950 mm by 1420 mm, with a 20-litre oil reservoir. Processing accuracy is quoted at a surface straightness tolerance of ±0.1 mm and a surface roughness of Ra 12.5 μm.

The machine is designed for aluminum extrusion profiles used in fenestration systems. Six combination punching dies are mounted on a disk worktable, and each die can be brought into position by rotating the table, so multiple hole patterns (drainage slots, lock pockets, handle holes, and mounting apertures) can be produced on a single machine without manual die swapping. The hydraulic circuit uses a fixed-displacement pump with a 20-litre tank, typical for compact punching stations in this class. The 50 kN pressing force is standard for aluminum wall thicknesses of 1.4 mm to 3.0 mm found in residential and light commercial window frames. The ±0.1 mm straightness tolerance aligns with common assembly clearances in curtain-wall and window-line production.

Buyers are typically aluminum window and door fabricators, curtain-wall subcontractors, and profile finishing shops. The machine suits batch production where multiple punch patterns run in sequence. The supplier is located on Jiqi Road in Jinan, Shandong Province, a region with a dense cluster of aluminum processing equipment manufacturers. Trade terms, lead time, and packaging are not stated in the listing and should be confirmed with the supplier directly. Importers should verify voltage compatibility, die availability for their specific profile series, and whether commissioning support is offered.

Jinan Kingdear Machinery Co.,Ltd is located at 218 Jiqi Road, Jinan City, Shandong Province, with the postal code 250000. The company holds a harbor trust tier on the platform and currently shows a response rate of 0.00 percent with an average response time of zero hours, which indicates that response data is either not yet collected or not yet representative. The supplier's profile does not state year of establishment, registered capital, production floor area, or employee headcount, so any such figure would need to be confirmed directly with the company.

The listing presents a single aluminum punching machine for window and door profile fabrication, with technical parameters given in detail but without pricing, minimum order quantity, packaging specification, quoted lead time, or stated certifications such as CE or ISO. Buyers should treat this as a machinery quotation stage and request a formal proforma invoice along with references from other window machinery importers before committing to an order.
