Residential Air Conditioner & Refrigerator Making Machines

Nantong Zhenhuan Trade Co., Ltd. is specialized in machines for fabricating & manufacturing home-used split air conditioners, refrigerators & fridges, as well as machines for other heat exchanger purposes.

    1. Air Conditioner Fin Punching MachineFor split air conditioners production, aluminum / copper fin punching is the first step. There are various punching press machines in different speeds and configurations. We can provide you aluminum / copper fin punching press machine lines with progressive dies according to your fin size and desired productivity.
    1. Hairpin Tube BenderHairpin tube bender is for bending copper tubes into long U shape for condenser coils used in air conditioners or other heat exchangers.
      It can straighten & burrless cut coil copper tubes and then bend them into long U shape full automatically. No operator is needed.
    1. Vertical Tube ExpanderThere are vertical type and horizontal type. For home-use air conditioners, vertical type tube expander is enough.
      It can expand copper tubes, enlarge tube ends and flare tube ends in one cycle, to make copper tubes and aluminum/copper fins connect tightly for better heating exchanging efficiency.
    1. Return Tube Bending MachineThis return tube bending machine is specially designed for decoiling, straightening, bending, and cutting coil copper tubes into return U bends and crossover C bends, used in air conditioners and heat exchangers.
    1. Copper Tube Straightening & Cutting MachineThis copper tube straightening & cutting machine is for straightening coil copper tubes, detecting length and burrless cutting automatically.
      This machine adopts pull-apart cutting technology which is the most advanced cut-off method in the world, which eliminates or minimizes tube ID reduction that could occur and brings burr-less cutting results as well.
    1. Bundy Tube Straightener & CutterBundy tube is one kind of galvanized iron tube diameter 4.6mm ~ 10.6mm, used in automotive and refrigerator. This machine is just for straightening coil Bundy tubes and detecting length and burrless cutting automatically.
      This machine adopts same pull-apart and orbital cutting technology.
    1. Capillary Tube Cutting & Beading MachineThis capillary tube cutting & beading machine is for fully automatic straightening of copper capillary coil tubes, detecting length, pre-stretching, beading, and burrless cutting.
    1. Copper Tube Flaring & Cutting MachineThis copper tube flaring & cutting machine combines straightening and end flaring, offering decoiling, straightening, burrless cutting and one end flaring, widely used for copper/aluminum tube processing.
    1. Copper Tube Straightening Flaring & Bending MachineThis copper tube straightening flaring & bending machine is specially designed for decoiling, straightening, end forming, bending, and cutting coil copper tubes into different shapes, used in air conditioners and heat exchangers.
    1. Bundy Tube Serpentine Bending MachineThis machine is specially designed for bending multiple round Bandy tubes to be serpentine shape for refrigerator condensers.
      This machine is comprised of auto clamping & feeding device, auto bending head and PLC control system.
      This machine is PLC control, HMI operation.
    1. Copper Tube End Forming MachineThere are many kinds of tube/pipe making, rolling and processing machines, like post-tension corrugated pipe forming machine, spiral filter core forming machine, flexible hose forming machine, steel pipe welding machine, tube swaging machine etc.
