How to choose a good CNC spring machine

        There are many types of CNC spring machines. Each type has different strengths and weaknesses depending on the price. However, this cannot be seen from the outside, and only when used can we find the gap.

       The CNC spring machine is a high-end product. Like the notebooks that people often use, the appearance looks no different. However, once used, it will find that the boot speed is much different, and the accessories and running speeds inside are very different. Therefore, when purchasing the CNC spring machine, it is best to purchase according to your own use requirements, do not blindly purchase, or it is easy to buy a spring machine that does not meet the requirements, the spring can not be said.

        When purchasing CNC spring machine, it is best to choose the products of big brands. First, the quality is guaranteed. Second, there is guarantee after sale. To buy the spring machine to be used, the price is second, and all aspects should be considered.

What is the reason why the pe zipper bag machine is not tightly sealed?

        Different types of bag making machines have different requirements, mainly to see the characteristics and use of the bag making machine model, as well as the material of the bag.

         Pe zipper bag machine is not sealed for any reason? This is to see the side seal of the bag making machine, or the bottom seal. If the edge seal is not strong, you need to look at the bag on both sides and the seal on the other side is not strong. If the two sides are not strong, it may be that the cutter is too profitable. If the one is not strong, the angle of the knife may not be adjusted.

         Also need to check whether the temperature of the equipment has reached the sealing temperature of the bag-making material. If the bottom of the bag is sealed, the general sealing is not strong. The pressure is mainly reflected in the sealing knife. Check whether the heating plate of the sealing knife is damaged or not. Also check if the cutter temperature is not up to standard.

        There is also the product printing position. If the sealing position is very low and close to the edge, then the sealing at this position is not strong, the material is too slow, and it is not easy to seal.

       In summary, the zipper machine is not tightly sealed and can be checked in these aspects.pe zipper bag machine

Why does the Hot melt adhesive turn black after heating?

       Why does the Hot melt adhesive turn black after heating?

        The color of Hot melt adhesive generally does not change much before and after heating, but it may sometimes be black when it is found in actual use. What is going on?

        At the time of production, the hot melt adhesive generally changes in color due to the added content and components. After the production is completed, what color is the colloid at normal temperature, and there is no obvious change in the general color after heating and dissolving, but there are also many factors that will change the hot melt adhesive.

        It may be that there is too much carbide in the rubber pot, and there may be some glue remaining in the rubber pot. After many long-term work of hot melt adhesive equipment, the equipment operator did not have the awareness of cleaning the plastic pot. In the case of cyclic heating, the performance degradation of the hot melt adhesive is intensified, and it may cause more and more carbides in the pot, and the carbide hinders the performance of the glue.

       If it is not cleaned up in time, the amount of impurities may be mixed with a lot of black impurities, so the glue will easily turn black.

      Of course, it is also possible that the quality of the hot melt adhesive itself is not good, resulting in variation at high temperatures. The molecular structure variation caused by the reaction between raw materials may not only break the original characteristics of the raw materials, but also cause color changes, which may not necessarily turn black, or may become other colors.

What is the skill of 304 stainless steel sheet welding?

 304 stainless steel sheet welding process is necessary to apply pressure to the weldment, can use the metal material lower than the melting point of the base material to make the brazing material, or use the liquid brazing material to wet the base material, thus filling the gap of the joint, The link weldment can be realized after the mutual diffusion with the base metal. This is generally suitable for the welding of various materials, and of course for the welding of different metals and heterogeneous materials.

         During the welding process, the melting of the workpiece and the solder forms a molten region, and the molten pool solidifies and forms a joint between the materials. In the process, it is usually necessary to apply some pressure. There are many choices for welding energy, such as gas flame, arc, laser, electron beam, friction and ultrasonic.

Several aluminium glass window cleaning methods

         Nowadays, many people use aluminum doors and windows for doors and windows, but aluminum is a special metal material. Many people don't know much about its characteristics. It is inevitable that some people will be overwhelmed when cleaning. Today, I will teach you how to clean some aluminum alloy doors and windows. Let's go.

        The general aluminium glass window can be cleaned with a soft cloth dampened with water or a neutral detergent, but it is best not to use ordinary soap and washing powder, or to clean the strong acid and alkali detergents such as detergents and toilets. Will corrode the surface of the profile.

         Sealing tops and glass glue are the key structures to ensure the insulation of aluminum doors and windows. If these materials fall off, it is necessary to repair them in time or to keep the glass and door and window frames dry and tidy. In general, check the connection parts of the door and window frames and damage them. Parts should be tightened or replaced in time. Some parts that are relatively easy to damage, such as positioning pin, wind bracing and floor springs, should be checked from time to time. If the use is not flexible, it is necessary to regularly add lubricating oil to keep it clean and normal.
