Do you need to punch holes when using screws to connect aluminum profiles?

Screws are also called bolts, and there are many kinds. Different screws have different uses. If they are used together with nuts, they are only used to install accessories, so there is generally no need to punch holes. You can put the screw or nut into the groove of the profile first, and then fix it with the nut or screw. Commonly used screws are: flat machine bolt, T-bolt and so on.

If it is a connecting screw that can fix two profiles, it needs to be punched in the predetermined position. The size of the hole should be determined according to the size of the bolt. Commonly used bolts are: special semi-circular head bolts, hexagon bolts and so on. Bolted connection is hidden inside the profile, so it is beautiful in appearance. Moreover, punching holes can increase friction and make the connection stronger.

Matters needing attention in protective cover of aluminum profile equipment

Equipment shields made of aluminum profiles can be seen in many factories, because they are easy to assemble and disassemble, and can be flexibly designed to meet various styles and requirements. The protective cover of aluminum profile equipment is used for safety, whether it is the machine itself or the operator. So what are the precautions for the protective cover of aluminum profile equipment?

The first is stability. When the machine is running, it will vibrate. Therefore, the protective cover of the machine should have certain stability, so that the machine can operate normally. Here, it is necessary to choose a suitable aluminum profile specification to make it, so as to bear the due weight and avoid shaking.

Second, the structure and layout should be reasonable. At the beginning of the design, we should consider the possible factors clearly, so that the machine protective cover can be used reasonably and will not cause trouble in subsequent modification. It is also considered that the protective cover of the machine should be coordinated with the environment in which it is used.

Third, the panel used should be selected according to the usage. The types of panels are acrylic board, glass board, aluminum-plastic board, sheet metal parts, PVC board and so on. If you want to observe the running condition of the machine, you should use a panel with a good view, and if you need to block the light, you need to use an opaque panel. So we can't choose a panel that doesn't suit us just to look good.

Differences between European standard aluminum profiles and national standard aluminum profiles in assembly line

People who use industrial aluminum profiles in the industry know that assembly line aluminum profiles are divided into European standard and national standard, so what is European standard aluminum profile and what is national standard aluminum profile?

Many customers believe that European standard aluminum profiles are aluminum profiles produced according to European standards, and the dimensional accuracy will be higher than the requirements of national standards. The national standard aluminum profile is produced according to domestic standards, and its accuracy is slightly lower than that of the European standard aluminum profile. In fact, it is not such a distinction. 

The difference between European standard and national standard aluminum profiles in the industry lies in groove and chamfer.

1. Different aluminum profiles have different groove types, and different nuts are placed in the groove when the aluminum profiles are fixedly connected. The notch of national standard aluminum profile is square, and ordinary square nuts are placed. The notch of European standard aluminum profile is trapezoidal, and special special-shaped nuts need to be placed.

2. The corner chamfers of aluminum profiles are different, and the four corner chamfers of national standard profiles are very small, almost right-angled. The four corners of the European standard aluminum profile have large arc chamfers.
