What are the important contents of the door embossing machine?

Working features
Structure type
Drive system
Working medium
Common failuresDoor embossing machine is a special machine for making and forming patterns for security doors, steel doors, interior doors, stainless steel doors, iron doors, etc. In recent years, it has been popular among security door manufacturers, steel wholesale markets and other factories. The machine has the features of high efficiency, convenience, safety, energy saving, beauty and low cost. The surface of the embossing roller has a clear pattern to ensure the quality of embossing on the surface of metal sheet. Many of our experienced engineers have improved the design to make the machine simple in structure and excellent in performance. Easy to operate and easy to learn, a person can learn how to do it in just a few minutes.

What machines are needed for steel door production?

press brake, shearing machine, punching machine, door embossing machine, door frame embossing machine, door frame cutting machine, folding machine, hot press machine, transfer printing machine, laser cutting machine, CNC V-grooving machine.

You can visit this link to know more details:

What is the hot press machine?

A hot press machine is a device that heats two pre-fluxed and tinned parts to a temperature sufficient to melt and flow the solder, cure it, and form a permanent electro-mechanical connection between the
part and the solder. The heating up speed is selectable according to different products.

What is the thickness of a door?

Common thickness is one and three-eighth inches with the other options being 1.5. one and five-eighth, and one and three-fourth inches. Especially large or oversized varieties with a height over 90 inches or a width of over 36 inches tend to be thicker than the standard door sizes

How do you make a simple steel door?

1. Production preparation before steel structure processing
1) Technical preparation: drawing review, in-depth design, processing and production plan, process test.
2) Material preparation: procurement, inspection, storage.
3) Equipment preparation: transportation, processing, welding, painting, testing.
4) Labor organization preparation: special operation certificate, pre-job training, technical disclosure.

2. Manufacturing process of steel structure
1) Lofting, number material
① Lofting: The first process in the steel structure manufacturing process is to draw the entity of the product or the parts and components on the lofting table or at the scale of 1:1 according to the shape and size required by the product construction details or the parts and components drawings. On the flat plate, the process of obtaining the actual length and making the model.
② No. material: Draw the actual sample of the component on the steel according to the template, and mark various processing marks to prepare for the cutting and blanking of the steel.
2) Cutting: Cutting is to separate the shape of the parts of the staked and numbered materials from the raw materials. Commonly used cutting methods are: gas cutting, mechanical cutting) and plasma cutting.
3) Forming: According to the design requirements, the process method of bending the plate or section steel into a certain shape using processing equipment and certain tooling molds. Generally, there are two methods of cold bending and hot bending.
4) Correction: Steel will be deformed during storage, transportation, hoisting and processing, and steel and components that do not meet technical standards must be corrected. Correction methods: flame correction, mechanical correction and manual correction.
5) Edge processing: edge processing methods are: shovel edge, planing edge, milling edge and carbon arc gouging edge.
6) Hole making: including rivet holes and bolt holes, which can be drilled and punched. The allowable deviations such as hole-making accuracy and hole spacing should comply with the design and specifications.
7) Assembling: also known as assembling, assembling, and assembling, it is to assemble the processed parts and semi-finished components into independent finished products according to the requirements of the construction drawings. The methods of assembling steel structures include ground-sampling method, copy-copying assembly method, vertical assembly method, horizontal assembly method, and tire mold assembly method.
8) Welding: Welding is a key step in the fabrication of steel structures.
9) Milling end, drilling mounting holes and friction surface treatment
10) Rust removal, painting and numbering

3. Steel structure pre-assembly
Due to the limitation of the capacity of transportation and installation equipment, or in order to ensure the smooth progress of the installation, a plurality of finished components are set and assembled in the factory according to the space required by the design to check the connection between the parts, which is called pre-installation. assembled.

What are the types of folding machines?

Manual folding machine:
This series of manual folding machines is developed on the basis of summarizing the production and use of manual folding machines for many years. It integrates the advantages of various manual edge folding machines. A box or plate with four sides and one bottom. Moreover, a flange can also be folded on the upper part of the box. When all the upper dies are installed, the straight sheet can be folded.

Mechanical folding machine:
An edge folding machine is a machine that processes the edge of the product. For example, a lithium-ion power battery automatic folding, packaging and folding machine adopts a multi-station rotating cycle method. The lithium-ion power battery is folded and packaged through three stations. , has the characteristics of low cost, stable performance, high degree of automation, and convenient adjustment.

The lithium-ion power battery is folded and packaged through three stations. , has the characteristics of low cost, stable performance, high degree of automation, and convenient adjustment.

The folding machine is a simple bending machine, which can be either manual or motorized. The easiest way to do this is to use a model with a bending radius to hold the steel plate firmly on the machine table. The protruding part of the material is placed on another table that can be rotated around the center of the bend radius. As the movable table rises, it bends the stainless steel to the desired angle. The stainless steel slides on the table when the bend is made. Therefore, to prevent scratching the stainless steel, the surface of the workbench must be smooth. In actual processing, the stainless steel surface is usually protected with a plastic film.

How do you manufacture a steel door?

What Is Galvanealed Steel?
Galvanised steel is a steel surface that's received a galvanized coating that has been annealed, which is a process of heating and allowing to cool slowly, to make it easy to paint.

How does the Steel Get Shaped?
Next the steel doors go through a process called Shearing. This process cuts the sheet metal to the specified size needed for manufacturing.

Spot Welding The Metal Doors
One of the most important parts of the metal door manufacturing process is called Spot welding. Spot Welding is used to attach hinge, closer and lock reinforcements within the body of the door, as well as securing any additional stiffeners.

After the steel shell is assembled, a core is then added to the door. The core is used not only to provide a more rigid door, but also allows for additional features such as energy efficient door insulation, bullet resistance and sound proofing. There are three types of door cores: Honey Comb core, the steel stiffened core, and finally the polystyrene core. While in past the honeycomb core was most popular, environmental efficiency in modern buildings has demanded that a polystyrene core door become an industry standard.

Finishing The Door With Some Edge Welding
Finally, after all the components of the door are assembled, the metal door is then placed through a machine called an edge welder. This automatic welder merges both of the edges of the two door halves into one finished product.

The next step is to move the door into the finishing room. Here workers grind the edges of the weld down to a smooth finish, and make any finishing touches by sanding imperfections and stains. The door is then inspected one last time for quality before being mounted to hangars and entering the painting booth.
