First, buy to see paint
1, see, touch the fullness of the paint film, this will have to compare several times will read. The fullness of the paint film indicates that the paint is of good quality, has a strong cohesive force, and has a good seal on the wood. At the same time, it shows that the painting process is relatively complete and there is no suspicion of cutting corners;
2. Oblique side of the station to the door to find the reflective angle of the facade, to see if the surface of the paint film is smooth, orange peel phenomenon is obvious, there are no protruding small particles. If the phenomenon of orange peel is obvious, it indicates that the baking process of the paint film is not closed;

3, fancy style door, depends on the shape of the edge of the line, in particular, the inside corner (that is, can not see the angle) but there is no film cracking phenomenon.
4, then ask the type of paint, the basic answer is PU paint (polyurethane paint), we note that the advantages of PU paint is easy to sand, the process saves time and effort, the disadvantage is the film is soft, a slight bump easily produce white shadow dent. If at least one layer in the lacquer layer is a PE lacquer, this will be greatly reduced. The advantage of PE paint (polyester paint) is that the paint film is hard, the hiding power is strong, the transparency is good, and the veneer texture can be expressed better. The disadvantage is that it is difficult to polish, the processing process is time-consuming and laborious, and most manufacturers do not want to use PE coating.
Second, look at the surface roughness
1, veneer blisters, indicating that the veneer in the process of attachment uneven heating, or coating uneven, flat hot press machine can be calculated to solve the flat door when the skin is heated uneven problem;
2, the flatness of the wooden door surface is not enough, indicating that the use of cheaper plates, plate flatness is not enough, you can imagine the environmental performance is also very difficult to meet the standard, a little leaf to know what it means;
3, to see whether the process is uniform and small joints: see whether the process is uniform and even small joints, this point is almost the same as the election of the car, a direct reflection of the company's integrated level of technology;
4, to see the installation quality: Although the finished product door is completed in the factory, but it is truly a product to the customer to use the product is completed, so the door is only considered semi-finished products, installation is the key link. Good installation procedures, good installation tools, and experienced installation technicians are the keys to success.
Third, look at the hardware
Finally talk about hardware, hardware is a very easy to let the wood door manufacturers and customers in determining the quality of the door to wrap things, it is recommended that customers try not to buy their own hardware parts, if the manufacturers can not provide a satisfactory hardware products, their choice must be selected Brand-name manufacturers of hardware products, such products are generally lifetime warranty.
