Once the straight line mark is cut off, it means that the screw is Has been moved by other people and has left the initial position. As long as you look at the color, you can know who is responsible for this screw. As long as there is industry on the earth, the function of screws will always be important. Personnel can check the chassis of the vehicle here. are used for both large and small screws.

One is to mark the position of the screw after being tightened to check whether the maintenance personnel have inspected the equipment according to the specifications. Is this any use? It turns out that these color marks have two functions. The entire repair area is divided into two parts. Every night, when the joyous crowd disperses, Disneyland will enter the busy maintenance inspection phase. Screws have important tasks in industry. The screw manufacturer wants to say: Every screw has a story!

Disneyland is a place that brings happiness to people.The anti-theft screw should first detect the screw from the wire of the screw. In the screw forming, the first is the detection of the mold for the production of the screw. The appearance of the formed screw is inspected to see if there are burrs, and the size and length of the formed screw are inspected. There is also detection of thread pitch and so on. How smooth is the surface of the screw? The salt spray test detects the rust time of the screw or how many hours the salt spray screw passes before it rusts.

It Cement Board Screws Company is the inspection of the machine that produces the screws, which is conducive to safe and smooth production. The anti-theft screw is followed by the detection of the head forming of the screw. Ensure the quality of the screws. Screws that are opened by a good screw wire are more beautiful. The quality of a precision screw is directly related to the wire used to produce the screw. See if these dimensions and length meet the national standard or the specific requirements of the customer. All rules pass, only rules stop. Only a good mold can produce a good screw product.

The formulation of self-tapping screw performance standards suggests that our manufacturers should follow special standards as the basic standard while formulating self-developed self-tapping screws and self-tapping screw fastener product standards. There are two standards for identifying self-tapping screws and self-locking and anti-loosening screws or whether their performance is good or bad.

Despite the national military standards, only testing methods are provided. One is the national standard, and the military is the national standard. After entering the tempering furnace, iron oxide occurs due to the effect of carbon and temperature, forming a red rust color; The water quenching medium is used for a long time, and the rust prevention in the medium can be reduced to form part rust.

The way to deal with this question, such as pre-treatment before the screw feed into the heat treatment, that is, clean with alkali or acid, and remove the phosphate film on the surface China Concrete Screws factory of the workpiece. After the blackening agent is used for a period of time, usually half a year, the blackening agent must be exchanged throughout the tank. The application temperature should be maintained between 40-50 ℃, and it must be often mixed when not in use to keep the blackening agent in good condition.

The change to abrupt change will eventually damage the application function. For the above questions, the solutions are as follows: Remove the phosphating film; Improve the heating temperature of zone 1 of the mesh belt furnace; When using oil quenching agent, the reasonable temperature should be below 60°C to reduce the aging process of the oil; The control of the carbon potential in the furnace, under the premise of ensuring no decarbonization, reduce the carbon potential as much as possible; Always check the data of water quenching medium, and add rust inhibitor when necessary.

If you find that you are unwell, you must leave the job immediately and report it to the leader. When the machine is working, it is forbidden to reach into the working area of ​​the slider, and it is strictly forbidden to pick and place the workpiece by hand.
