11 January Another galvanizing process and action for the shackle surface - zinc-nickel plating

Zinc-nickel plating is the plating of Zinc and nickel on the surface of objects respectively to play the role of anti-corrosion, beautiful appearance and wear resistance.

Better corrosion protection

Zinc-nickel plating can prevent surface corrosion, especially in a humid environment, zinc has good rust resistance, can resist the oxidation of the surface of the object, to prevent the surface of the object rust. The nickel layer of galvanized nickel can prevent the zinc layer from losing its anti-corrosion effect because of oxidation, so as to achieve better anti-corrosion effect.

More beautiful surface

Zinc-nickel plating can improve the gloss of the surface of the object, make the surface of the object more smooth, and increase the beauty of the object. In many household goods, electrical appliances, etc., the application of galvanized nickel has been very extensive, because it can make items look more high-end and fashionable.

Abrasion resistance

The zinc layer and nickel layer of zinc-nickel plating can make the surface of the object harder, thereby increasing the wear resistance of the object. In some mechanical equipment, automobiles, etc., galvanized nickel is also widely used, because it can increase the wear resistance of the surface of the object and improve the service life of the object.

Electrolytic action

The zinc layer and nickel layer of zinc-nickel plating can form a battery and form a protective film on the surface of the object to prevent the surface of the object from losing its anti-corrosion effect because of oxidation. At the same time, this layer of protective film can also make the surface of the object harder and improve the wear resistance of the object.

Environmental protection

The application of zinc-nickel plating can reduce environmental pollution because it can make the surface of the object more durable, reducing the number of times people need to replace because of the aging of the item, thus reducing environmental pollution. At the same time, the application of galvanized nickel can also reduce waste generation, thereby reducing environmental pollution.

04 January The Difference between Haosail Mooring Swivel and Ordinary Swivel

Ordinary Swivel: It is made of two parts, a bolt similar to a D-ring and a D-ring, and then the two parts are connected together and a hex nut is welded on it. However, the hex nut is easy to rust and fall off. HAOSAIL Mooring Swivel: It is different from ordinary Swivel in that it is composed of three parts: Two D-rings and a Screw in the middle, the head of the Screw is thickened, the two D-rings are connected with the Screw, and then the D-rings and Screw are welded at the back bottom of it. It is true that the screw's head is not easy to fall off, and the surface is hot dip galv. We can do this production method, is much stronger.

01 November How to understand the meaning of CDD / CDK / CDH marking on the plate clamp?

Explanation of CDD / CDK / CDH marking on the plate clamp，typically indicate different models or variations of plate clamps. Here's a general understanding of the meanings associated with these markings: 1. CDD: This stands for "Close Die Dovetail." A plate clamp labeled as CDD is designed with a dovetail-shaped lower jaw. The dovetail shape allows the clamp to securely grip and hold onto a groove or recess in the workpiece. The CDD model is suitable for applications that require a high clamping force and stability. 2. CDK: This stands for "Close Die Knurled." A plate clamp marked as CDK features a knurled lower jaw. The knurled surface provides enhanced gripping power and prevents slippage, ensuring a firm hold on the workpiece. CDK plate clamps are ideal for situations where a strong and secure grip is necessary. 3 .CDH: This stands for "Close Die Hex." A plate clamp labeled as CDH has a hexagonal-shaped lower jaw. The hexagonal design allows the clamp to effectively grip hexagonal-shaped workpieces, providing stability and preventing rotation. CDH plate clamps are suitable for workpieces with hexagonal profiles. It's important to note that these markings may vary depending on the manufacturer or supplier of the plate clamps. Always refer to the manufacturer's documentation or product specifications to understand the specific features and capabilities associated with each marking. #rigging sling #lifting sling #wire rope #shackle #G80&G100 chain #hooks #thimble #master link #connecting link #ferrule
