Medium-density fibreboard (MDF) is an engineered wood product made by breaking down hardwood or softwood residuals into wood fibres, often in a defibrator, combining it with wax and a resin binder, and forming panels by applying high temperature and pressure.MDF have many advantages.

Firstly,cheaper than plywood. It is made up of separated fibres, but can be used as a building material similar in application to plywood.

Secondly, It is stronger and much denser than particle board.

Thirdly,making it more uniform than natural woods during cutting and in service.

Fourthly, Excellent substrate for veneers.

The main material of the MDF is Poplar,Eucalyotus,hardwood,pine ect

Possess:

Thick MDF adopts flat pressure line flow

①Peel the logs and break them into sawdust ②The wood chips are screened, cleaned, and put into the hot mold process, followed by dispersants and tree myron ③Drying, fiber screening, all raw materials into the glue, into the tank, continuous flat molding④Sawing MDF ⑤polishing⑥checking⑦packing

Thin MDF adopts rolling line flow

The third step of the sheet is to roll the sheet on both sides, the rest of the process is the same

The advantages of the sheet manufacturing process are: high density, good sandingDisadvantages are, thickness is not uniform, tolerance

The advantage of the thick plate production process are:Uniform thickness, stable product quality, small tolerance Disadvantages: low density, relatively poor sanding。

Common density board still has waterproof density board and hard boardwhich can be used to make picture frames.The density plates are graded as follows:E1 E2 E0 CarbP1,P2

common density board particle board,tubular particle board ect

PVC edge banding is made from PVC, extrusion products edge banding also can be made by ABS and Melamine, Acrylic, PE material. PVC edge banding's width ranges is from15mm to 650mm, thickness ranges is from 0.2mm to 3mm.PVC edge banding possess the characteristics of smooth and glossy surface appearance slight depigmentation, excellent flexibility, excellent bend.

It can be used for furniture, cabinet and equipment of schools, offices and laboratories.

Melamine edge banding is made of German raw paper and the plastic resin

Pvc main colors are:wood grain color,solid color,high glossy color,or as customized,

Application:Furniture, Cabinet, Offices, Cloakroom, Laboratory and so on.

Process:

Direct extrusion process①Mix different color powder materials together②After adjusting the color, put it into the extruder to extrude small particles③Directly into the extruder, extrude the edge bands of corresponding thickness and width④Printing colors and wood grain⑤Forming and packing⑥checking⑦Packing and shipping

Slitting process:①Mix the raw materials, mix the colors, enter the extruder, and extrude a long strip②Into the roller press, roll out the die of the corresponding width and thickness to form the background color③Printing and coloring, laminating a film on the surface, laminating④Slicing into corresponding width, thickness, forming⑤checkin⑥Packaging and delivery
