Jinzan Profile Bending Co., Ltd.

Application Areas: Real Estate, Sports Venues, Exhibition Centers, Museums, Shopping Malls, Airports, High-speed Railway Stations and all other construction fields.

Main Materials: Aluminum alloy window and door profiles, UPVC (Unplasticized Polyvinyl Chloride) window and door profiles, stainless steel window and door profiles, etc.

Process Flow: Manufacturing sophisticated molds and shaping tapes for filling; protecting the outer surface of materials during the bending process to prevent abrasion; controlling the deformation of profile interfaces during the bending process.

Process Characteristics: Direct processing of finished materials; processable regardless of batch size; fast processing cycle.

Application Areas: Large public construction projects, large sports venues, airport terminals, high-speed railway stations, exhibition centers, intercity bus terminals, museums

Main Materials: Various types of round pipes, rectangular pipes, square pipes, angle steel, channel steel, I-beams, H-beams, C-channels

Process Flow: Cold bending processing, hot bending processing

    Cold bending processing: Shaping materials by applying external force through mechanical equipment to make the materials reach a certain yield limit for forming

    Hot bending processing: Mainly used for materials that cannot be bent by cold bending or when the bending radius is too small

Process Characteristics:

    Cold bending advantages: Low cost, short processing time; disadvantages: Unable to process large cross-sections or small radii

    Hot bending advantages: Capable of processing profiles with any cross-sections; disadvantages: High cost, long processing time

Technical Features: No change to the outer shape of materials, no material deformation, good flatness.

Application Areas: Large sports venues, airport terminals, high-speed railway stations, exhibition centers, museums, residential real estate, schools, hospitals, and various other construction fields.

Main Materials: Aluminum alloy curtain wall profiles, aluminum crossbeams, aluminum square tubes, aluminum gratings, aluminum louvers, aluminum sheets.

Process Flow:

    First, create molds, then produce precision backing plates to protect the outer surface of materials from scratches during processing.

    After bending and forming, conduct precise arc verification to ensure accuracy.

Process Characteristics:

    Direct stretch bending and delivery of finished profiles.

    Bent finished products can be directly installed on-site without secondary processing through other techniques.

Application Areas: Aerospace, automotive, high-speed rail carriages, coach bodies, bus bodies, ships.

Main Materials: Aluminum alloy profiles, steel profiles, stainless steel profiles.

Process Flow: Manufacturing molds according to the cross-sections of profiles, using appropriate supports, precision shaping tapes, and high-precision backing plates; after bending and forming, the profiles are verified with precision instruments.

Process Characteristics: High precision requirements, relatively high difficulty coefficient, and strict demands on the R&D capabilities and innovative capabilities of enterprises.

Application Areas: Wide-ranging applications including residential interior finishing, large shopping malls, jewelry display cabinets, airports, high-speed railway stations, and large venues.

Main Materials: Stainless steel sheets.

Process Flow: Cutting stainless steel sheets → grooving → corner folding → forming → stretch bending processing.

Process Characteristics: Eco-friendly, highly practical, customizable for any batch size, short processing cycle with fast turnaround.
