Screw Anchor Factory

Cold Forming Anchors are fasteners used in marine applications. They are typically available in blue, white, or stainless steel. Marine versions can be custom-made for specific applications. These fasteners use a mechanical interlocking system based on torque moments applied to a screw contained within a plastic sleeve. When this screw is inserted into a hole, it forces the anchor to be pressed against the wall of the hole.

When choosing an anchor, it is important to ensure that the strength of the product is appropriate for the application. To do this, you will need to evaluate the strength and durability of the cold form anchor. In addition, you must check the anchor's bolts for damage. You will also need to adjust the nuts if the anchor does not have threads.

When installing the anchor in concrete, you should start by drilling a hole that is larger than the diameter of the anchor. Once the hole is prepared, insert the anchor, clipped end first. Then, using a hammer, insert it slowly and carefully until it is completely embedded into the concrete. Make Cold Forming Anchor  sure the threads are at least two to three inches below the surface of the concrete. This will give the anchor enough room for the washer and nut.

Cold-formed anchors are typically used to connect precast reinforced concrete elements. Experimental and numerical studies are used to evaluate the mechanical behavior of the two most commonly used anchors. This investigation compares a patented sliding block bolt with a commercially available bolt. These studies provide insight into the mechanical behavior of the two bolts and the tensile load bearing capacity of the connection for two different working configurations.

Anchor channels are often used in industrial and residential buildings to connect precast structural elements. They can also be used to connect elevator rails, parapets, and mechanical systems. In addition, anchor channels are structurally sound and dust-free. For these reasons, cold-formed anchors are an excellent choice for many different applications.

OEM Cold Forming Anchors are available in a variety of materials and can be used in marine applications. They are typically available in stainless steel, blue, and white, with some versions specifically suited for marine use. Designed to fit in tight spaces, they are tightened by applying a torque moment to a screw inside a plastic sleeve.

OEM Cold Forming Anchors are a more cost-effective alteative to custom cold formed anchors. They offer the same high-quality and flexibility, but are much more affordable. Additionally, they are Cold Forming Anchor  versatile and provide a cost-effective way to produce various types of fasteners. OEM Cold Forming Anchors are a great alteative for companies who are looking to save money on production while ensuring the quality of their end product.

When installing an anchor, the clipped end of the anchor should be inserted first, and the anchor should then be hammered to embed a certain distance into the concrete. The threads should be at least two to three inches below the surface of the concrete. This should provide enough space for the nut and washer.

Bolts mainly play the role of connection and fastening, and their quality directly affects the connected parts. In order to prevent the surface wear and corrosion of the bolts, most people choose to surface treatment of the bolts, and hot-dip galvanizing is a commonly used method. Hot-dip galvanized bolts are also called hot-dip galvanized bolts. After removing the oil stains and rust on the surface of the bolts, they are immediately immersed in an aqueduct containing zinc liquid, and a zinc layer is formed on the surface of the bolts to prevent direct exposure, oxidation and wear of the bolts.

The surface treatment cost of hot-dip galvanized bolts is low, the corrosion resistance is good, and it can be kept free of rust for 15 years during use. The thickness of the zinc coating of hot-dip galvanized bolts is greater than 50 microns. The protective film of zinc oxide, zinc hydroxide and basic zinc carbonate formed on the surface of the zinc layer by atmospheric corrosion can slow down the atmospheric corrosion of the zinc layer.

Hot-dip galvanized bolts are not only plated with a thicker zinc layer, but also form a zinc-iron alloy layer. This plating method not only has the corrosion resistance of electro-galvanizing, but also has a strong incomparable with electro-galvanizing due to the zinc-iron alloy layer. Corrosion resistance, so this plating method is especially suitable for strong corrosive environments such as various strong acids and alkali mists.

principle
When the zinc is liquid, the hot zinc layer is formed through three steps, and the surface of the iron base is dissolved by the zinc solution to form a zinc-iron alloy phase layer. The Steel Masonry Concrete Screw Anchor Manufacturers  zinc ions in the alloy layer are further diffused onto the substrate to form a zinc-iron mutual soluble layer, and the surface of the alloy layer is surrounded by the zinc layer.

Features:

1. The surface of the bolt is covered with a thick layer of pure zinc, which can avoid the contact between the steel matrix and any corrosive solution and protect the bolt matrix from corrosion. Generally, a very thin and dense zinc oxide layer is formed on the surface of the zinc layer, which is insoluble in water and has a protective effect on the base of hot-dip galvanized bolts. more ideal.

2. It has a zinc-iron alloy alloy layer and has compactness, showing corrosion resistance in seawater salt spray environment and industrial environment. Due to the strong bond, zinc and iron are mutually soluble and have strong wear resistance.

3. Since zinc has good ductility and its alloy layer adheres firmly to the steel substrate, hot-dip galvanizing can be used in various forming processes such as cold punching, rolling, wire drawing and bending without damage coating.

4. After hot-dip galvanizing of steel structural parts, it is equivalent to one-time annealing treatment, which can effectively improve the mechanical properties of the steel matrix, eliminate the stress during forming and welding of the steel parts, and is conducive to the tuing of steel structural parts.

5. The surface of hot-dip galvanized bolts is bright and beautiful, and the pure zinc layer is a plastic galvanized layer in the process of hot-dip galvanizing. Its performance is basically close to that of pure zinc, and it has good ductility.

Compared with other processing techniques, cold extrusion has the following advantages:

1) Save raw materials. Cold extrusion is the use of plastic deformation of metal to make parts of the desired shape, which can greatly reduce cutting and improve material utilization. The material utilization rate of cold extrusion can generally reach more than 80%.

2) Improve labor productivity. Using cold extrusion process instead of cutting to manufacture parts can increase productivity several times, dozens of times, or even hundreds of times.

3) The workpiece can obtain ideal surface roughness and dimensional accuracy. The precision of the parts can reach IT7~IT8 grades, and the surface roughness can reach R0.2~R0.6. Therefore, parts processed by cold extrusion are generally rarely re-cut, and only need to be fine-ground where the requirements are particularly high.

4) Improve the mechanical properties of parts. The cold work hardening of the metal after cold extrusion and the formation of reasonable fiber streamline distribution inside the part OEM Cold Forming Anchor Fasteners Manufacturers  make the strength of the part much higher than that of the raw material. In addition, a reasonable cold extrusion process can form compressive stress on the surface of the part and improve the fatigue strength. Therefore, some parts that originally need heat treatment and strengthening can be omitted after cold extrusion process, and some parts originally need to be made of high-strength steel, and can be replaced by lower-strength steel after cold extrusion process.

5) Parts with complex shapes that are difficult to be machined can be machined. Such as special-shaped sections, complex inner cavities, inner teeth and inner grooves that are invisible on the surface.

6) Reduce the cost of parts. Because the cold extrusion process has the advantages of saving raw materials, improving productivity, reducing the amount of cutting of parts, and replacing high-quality materials with inferior materials, the cost of parts is greatly reduced.
