How to Process Air Conditioner Shell With CNC Plate Rolling Machine?

The outer shell of the air conditioner or some internal metal air ducts usually use CNC plate rolling machines to bend the flat metal plates into specific shapes and curvatures according to design requirements to meet the shape of the outer shell or the structural needs of the air duct, making the manufacturing of air conditioner components more accurate and efficient. When choosing air conditioner materials suitable for plate rolling machine processing, two aspects should be considered:

1.Ductility of Air Conditioner Materials

Materials with good ductility can withstand large deformations and are not prone to cracks or breaks when bent by plate rolling machines. For example, aluminum alloy materials have good ductility and are suitable for processing air conditioner components with complex shapes and large bending degrees, such as some decorative housings of air conditioners or more delicate internal air duct components.

2.Thickness of Air Conditioner Materials

It is necessary to consider whether the thickness of the material meets the processing range of the plate rolling machine. Different types of plate rolling machines have different processing limits for material thickness. If the material is too thick, it may exceed the processing capacity of the CNC plate rolling machine, resulting in reduced processing accuracy or equipment damage; if the material is too thin, problems such as excessive bending or wrinkling may occur during processing. Generally speaking, for the shell parts of small air conditioners, it is more appropriate to use materials with a thickness of 0.8 – 1.2mm.

After determining the material, it is time to choose a plate rolling machine. Here, Shanghai ANTISHICNC engineer recommend a CNC four-roller plate rolling machine suitable for air conditioner processing. The model reference is as follows:

Model	W12-16×3000
Upper roll diameter	Φ320mm
Lower roll diameter	Φ300mm
Side roll diameter	Φ250mm
Maximum rolling plate thickness	16mm
Maximum pre-bending thickness	12mm
Maximum coil width	3000mm

This W12-16×3000 CNC plate rolling machine has strong processing and forming capabilities. For the outdoor unit shell of the air conditioner, the internal metal air duct and other parts that require specific shapes and curvatures, it can accurately bend the metal sheet into the required shape and can achieve continuous bending processing. The CNC plate rolling machine can also automatically complete the curling process according to the preset program. For the processing of a large number of metal parts in air conditioning manufacturing, the high efficiency of the plate rolling machine can effectively shorten the production cycle and improve production efficiency.
