Introduction to Process of Production

Chromating Line

The chromating line is to clean the lubricating grease and antioxidative grease adhesive to the surface while being rolled, and other impurities such as silicon,- magnesium, iron and copper that deposit on the surface of aluminum materials.The company uses qualified industrial chemicals and advanced technology from German Henkle co,. ltd. to have a chromating dealing with the surface of aluminum materials.Through this technology, the aluminum surface is covered with a honeycomb oxidative coating of high density,which becomes an agent to make paint and aluminum firmly adhesive with each other. This agent has very strong adhesive force.

Precision Coating Line

The precision coating line is to coat the chemisynthesized aluminum roll with various paints according to the needs of the customers. The company has an advanded three-roller reversal precision coating machine that can operate under sealed, dustless condition so that the thickness of coating and its outer appearance are under proper control.The oven is divided into four temperature-controlled areas ± 1’C to make the coating reach the best condition in its solvent resistance. hardness, flexibility and good glossiness, strong adhesive force and corrosion resistance.

Continuous Laminating Line

This is the key equipment of producing aluminum composite panel. It can make aluminum material. PE core and adhesive polyolefine film firmly adhesive to one another under high heat and high pressure so that the panel is smooth in its surface.With imported qualified adhesive Polyolefine film,advanced equipments, perfect technology and strict quality control:we have produced the aluminum composite panel whose peel strength is two times of the national standard and superior to the quality index of imported panels.

Processing Method

MED panel is very easy to process. All cutting, milling, slotting, side-folding and curving can be easily fulfilled by simple tools used for processing timber and metal. It can be shaped into various shapes, such as curve, reserve curve, curve corner and sharp curve,according to requirements of building design. It is incomparable for other decorating materials. Normal aluminum product processing machinery and wood product processing machinery can be used for processing of MED panel without special device.

Saw Cutting	It can be easily processed with wood product processing saw and plate saw. It’s recommended to use hard alloy blade.
Slotting	It’s important to make the V type slotting process with a distance of 0.2-0.4mm from the polyethylene substrate. The recommended slot angle is 110. · (1)milling machine and trimmer Use the modified drill as showed in the left chart. Running speed:20000-30000rpm Feed speed:3-5m/min Material: hard alloy · (2)When processing large quantity of V type slots, it’ s recommended to use round saw and belt saw. And the following is an example of slotter: · material: hard alloy flake · outer diameter:305mm · number of teeth:24 · running speed:3000-5000rpm · feed speed:5m/min
Bending with panel folder	If operated on the platform, bending part can be made very tidy
Bending with panel bender	When plate folder is used to finish the MED panel, dies shall be placed on with appropriate radius
Bending with 3-roller panel bender	3 – roller panel bender is more preferable for bending of large internal diameter to plate folder.
Riveting	Countersunk rivet can realize easy
Bolting	Considering from deformation limit, formulae>2D is the best calculation way of aperture D and distance from hole centre to plate end.
