How the embossing roller is made

According to the customer pattern requirements in the roller surface processing pattern. This is a crucial part of the embossing roller production process, requiring embossing roller production personnel to have rich experience, according to customer pattern requirements, to develop production processes. In the production process, the embossing division should be careful, careful and meticulous, and the patterns produced should be clear, rich in levels and strong in three-dimensional sense.

Now on the market so many varieties of embossing machine, but which is popular or automatic embossing machine, why this happens? In fact, the main function of the automatic embossing machine is more powerful, in the operation of the above more convenient and simple. Of course, there may be some other factors affecting it, and now people are more respected automatic machine, no matter which industry in the automatic machine is good

Although you have purchased the best equipment, if you cannot install the ultrasonic embossing machine correctly, you still cannot achieve good results. Then let's learn about the installation precautions with our experts. We know that there will be some bumps and collisions during transportation that may cause damage to our equipment, so after the packaging is removed, the surface of the machine is inspected to ensure that all parts are not damaged.

Why is the automatic embossing machine so popular?

Now on the market the embossing machine varieties so much, but which is popular or automatic embossing machine, why does this happen? In fact, the main function of the automatic embossing machine is more powerful, in the operation of the above more convenient and simple. Of course, there may be some other factors affecting it. Now people are more respected for fully automatic machines. No matter which industry, fully automatic machines seem to be more popular. In fact, this phenomenon is expected.

Maintenance of embossing roll

In the process of use, equipment maintenance and maintenance is very important. The staff of the embossing machine manufacturer told us that we also need to maintain it constantly in the process of using the embossing roller. After a long period of use, the embossing roller will rust, which will lead to the need to process the material pollution. Then we need to remove the rust. It is usually used to remove the rust from acidic liquid. In order to prevent the recurrence of corrosion, we usually have a certain anti-rust treatment. Sometimes there will be some oil stains on the embossing roller on the equipment. We will use colorless machines to remove the stains and keep them under pressure.

Steel plate industry is through the trough

With the steady growth of the economy, the demand for patterned steel plates has gradually improved. Although the pattern of oversupply of the steel plate industry chain has been formed, with the support of national policies, the steel plate industry is about to pass the trough. As we all know, the profit of steel plate is not declining for a day or two. Since last year, the profit of steel plate has basically declined. But not as obvious as this year. However, the hope of patterned steel plate marketers can still be seen. Now China is in a state of "three-phase superposition", economic development has entered a new state, and the economy is developing in a good direction.

Galvanized zinc steel sheet

Galvanized steel plate substrate is composed of 55% of aluminum, 43.5 of zinc and 1.5 of silicon alloy coating, its anti-corrosion ability of the same conditions of galvanized steel plate substrate 4-6 times, is used for roof, outside the wall is ideal material. Galvanized zinc plate has been proven to have the following characteristics: extraordinary weather resistance and the use of more than 20 years without maintenance. The recent test results of the early products of the roof/wall system show that the main body performance is intact without any maintenance under the action of decades of strong sun rays, exposure, erosion of industrial excrement and temperature stress. Worldwide over 0.5 billion

Introduction of curing process of color steel coil

In the production process of color steel coil, the substrate can pass through the baking furnace at a maximum speed of 140 m/min. In order to ensure a satisfactory curing time, the length of the baking furnace is generally 30~50m. After the substrate is painted, both sides are wet paint film. In order to make the substrate hang through the furnace chamber, there are generally two furnace types: air floating type and hanging type. The air flotation type uses the upward airflow in the furnace to hold the substrate. The overhang type uses the tension of the front and rear tension rollers of the strip to control the orientation of the strip steel in the furnace. Because the interval is long, the substrate will have a certain overhang degree. It is necessary to plan the furnace cavity into an anti-bow type. Color coating unit generally use hot air heating, there are also options
