7. Laser cutting machine<\/strong><\/strong><\/h4>\n\n\n\n

Generally used for processing doors with hollow patterns in the middle.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

8. Transfer<\/strong><\/strong><\/h4>\n\n\n\n

For the transfer of door surfaces, the transfer paper is placed on the door panel after it has been sprayed and then pushed into the transfer machine for transfer. The pattern of the transfer paper will determine the effect of the transfer.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

9. Welding<\/strong><\/strong><\/h4>\n\n\n\n

Welding the door sheet and small parts inside the facade that needs to be put in early, such as the hinge fixing plates, the upper and lower sealing plates, the main lockbox.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

10. Hot press machine<\/strong><\/strong><\/h4>\n\n\n\n

After the doors have been welded and formed, they are pressed in a hot press for a period of time to keep the surface of the doors flat.<\/p>\n\n\n\n

How to make the door frame <\/strong><\/strong><\/h3>\n\n\n\n

1. Raw material<\/strong><\/strong><\/h4>\n\n\n\n

The door frame is made of a cold-rolled sheet and is usually 290mm ~ 340mm wide.<\/p>\n\n\n\n

2. Formant<\/strong><\/strong><\/h4>\n\n\n\n

Door frame embossing machine<\/strong><\/strong><\/p>\n\n\n\n

The door frame embossing machine is pressing different patterns and forming on door panels. The feature of it is high precision and low efficiency. For different sizes, just change the mold, suitable for producing non-standard doors.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n
\"\"<\/figure><\/div>\n\n\n\n

Machine de formage de cadre de porte<\/strong><\/strong><\/p>\n\n\n\n

Generally used to produce mass production of standard doors of the same size. The feature of it is with low precision and high efficiency. One machine can generally only produce one size, not suitable for the production of non-standard doors.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

3. Perforation<\/strong><\/strong><\/h4>\n\n\n\n

The multi-head combination hydraulic punching machine<\/strong><\/strong><\/p>\n\n\n\n

The multi-head combination hydraulic punching machine is used to punch lock holes, corners, and hinge holes. It can ensure the correct size of the product. Because the combination punch is a multi-station punch, it is possible to work simultaneously the work efficiency can be greatly improved.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Electric punching machine<\/strong><\/strong><\/p>\n\n\n\n

For punching cat eyes, corners of upper and lower door frames, punching mounting holes, connectors, and other small parts.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

4. Cutting<\/strong><\/strong><\/h4>\n\n\n\n

The door frame is cut at a 45-degree angle and can be spliced into a right angle. There are manual and automatic cutting machines.<\/p>\n\n\n\n

5. Soudage<\/strong><\/strong><\/h4>\n\n\n\n

The door frame is made by welding together the reinforcement bars for the expansion screws, the cement cover plate and the 4 sides of the door frame. Inspectors, check and spot check the accuracy of the dimensions.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Spraying line<\/strong><\/h3>\n\n\n\n

The doors and frames go through the phosphating line before entering the next process, which ensures that the surface of the steel plate is cleaned of acidic embroidery material and put on a layer of phosphating film, which facilitates the adhesion of the plastic powder in the subsequent spraying process.<\/p>\n\n\n\n

\"\"<\/figure><\/div>\n\n\n\n

Assembly<\/strong><\/h3>\n\n\n\n

The door frame is assembled with the hinges and the door frame is assembled with the cat’s eye, doorbell, lock body, lock cylinder, and a leather strip.<\/p>","protected":false},"excerpt":{"rendered":"
