Import Cnc Vertical Four-Point Corner Crimping Machine — Buy in Bulk from Supplier in China

The CNC vertical four-point corner crimping machine model LM4-CNC-1800×3200A is a precision industrial tool designed to apply uniform crimps to metal profiles at four corners simultaneously. It operates on 380V/50Hz input voltage with a 7.5kW power draw and uses hydraulic pressure of 15MPa to ensure consistent force application. The machine accommodates profile widths up to 100mm and handles workpieces ranging from 500×500mm to 1800×3200mm in size, making it suitable for large-frame applications such as window and door manufacturing.

The machine’s air pressure system operates between 0.5 and 0.8MPa, consuming 0.45 litres per cycle, while the hydraulic oil reservoir holds 40 litres for continuous operation. The overall dimensions are 4500×2000×2600mm, and it is shipped in a wooden case for protection during transit. Standard industrial-grade hydraulic components and servo-controlled vertical actuators are typical in machines of this class, ensuring repeatable accuracy without manual adjustment. The design avoids pneumatic-only systems, relying instead on hydraulic stability for high-torque corner crimping.

This machine is commonly purchased by manufacturers of aluminum window frames, steel door assemblies, and architectural metal structures requiring high-volume, low-defect corner joining. Buyers typically require confirmation of cycle time per unit, repeatability tolerance, and tooling compatibility with standard profile types such as 6063-T5 or 6061-T6 aluminum. Trade terms are typically FOB Qingdao or CIF port of destination, with packaging in a wooden crate. Minimum order quantity and lead time must be confirmed directly with the supplier.

Jinan Tecno Machinery Manufacturing Co., Ltd. is based in the Tianchen Street Hi-Tech Area of Jinan, Shandong Province, China. The company is listed as an imported supplier with harbor trust tier, indicating it has passed basic export compliance checks but has no verified response rate or average response time on record. The listing does not disclose factory size, years in operation, or client names, and no certifications such as ISO or CE are referenced.

The supplier specializes in CNC-controlled machinery for metal forming, particularly corner crimping and profile joining equipment. The company’s focus appears to be on mid-volume production machines for the architectural aluminum and steel framing industries. No information is provided about R&D capacity, after-sales service, or technical support availability. Buyers should verify operational training and spare parts access directly before purchase.
