Service HotlineCopper nuts, also known as embedded nuts and embedded copper nuts or plastic embedded nuts, are divided into hot melt copper nuts, hot pressed copper nuts, embedded copper nuts and ultrasonic copper nuts according to different methods of use. This product is widely used in mobile phones. Shell / Pen meter shell / injection molding / insert of plastic parts, used as an internal thread. Generally embossed on the outer circle. To prevent sliding.
In the modern industrial field, products such as nuts and bolts are widely used to lock structural parts, but at the same time we also find that in many cases, especially when applied to vibration, we often need to lock the already locked Structural parts are regularly repaired and strengthened to prevent structural dislocation caused by loose nuts and bolts.
There are two types of bolt detection: manual and machine. Manual is the most primitive and the most commonly used consistent detection method. In order to minimize the outflow of defective products, general production enterprise personnel inspect the packaged or shipped products by visual means to exclude defective products (defects include tooth damage, mixed materials, rust, etc.). [2] Another way is automatic machine inspection, mainly magnetic particle inspection. Magnetic particle inspection is to use the interaction between the leakage magnetic field at the defect of the bolt and the magnetic powder, aiming at the difference between the magnetic permeability of the bolts (such as cracks, slag inclusions, mixed materials, etc.) and the magnetic permeability of steel, these materials are discontinuous after magnetization. The magnetic field at the place will be turbulent, and a leakage magnetic field will be generated on the surface of the workpiece where part of the magnetic flux leaks, thereby attracting the magnetic powder to form the magnetic powder accumulation at the defect—magnetic traces. The accumulation of these magnetic powders is observed and explained, and the purpose of rejecting defective products has been achieved.
The opening circlip is widely used in many industrial fields and plays a role in limiting the position of the parts. When in use, as long as the circlip is installed in the circlip groove of the part, the position of other matching parts can be effectively limited, so as to avoid the axial displacement of the matching parts. Since some opening circlips do not have circlip pliers installation holes, circlip pliers cannot be used and can only be installed by hand, which not only cannot effectively ensure the installation quality of the circlip, but also limits the efficiency of installation work.
The tail of the drill tail screw is in the shape of a drill tail or a pointed tail, and no auxiliary processing is required. Drilling, tapping and locking can be directly carried out on the setting material and basic material, which greatly saves construction time. Compared with ordinary screws, its toughness and pull-out force and maintenance force are high, and it will not loosen for a long time after combination, so it is safe to use. Especially in the combination of construction, construction, residential and other places, self-tapping and self-drilling screws are the best economical fasteners in terms of workability, cost and reliability. Now the construction of high-rise buildings and high-speed traffic in mainland China requires more high-quality drill screws;
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: providing hexagonal nuts, self-locking nuts with non-return, precision manufacturing stainless steel, headless screws and other products, we can provide you with suitable fasteners for you solution.
