GB12618
The information of GB12618  is as follows.
diameter:Â Â 3Â 3.2 4Â 4.8Â 5
length:Â Â 3Â 4Â 5Â 6Â 8Â 10Â 12
material:  304      carbon steel  aluminium
surface finishing:  natural     coating       galvanizing    and  so on
According to the material classification of the open-end blind rivets specified in GB12618, there are mainly the following categories:
– Aluminum alloy material: It has the characteristics of light weight and corrosion resistance, and is often used in fields such as aerospace, automotive manufacturing, and architectural decoration. For example, it is applied to the structural connections where there are requirements for weight and a certain degree of corrosion resistance is needed.
– Stainless steel material: It has good corrosion resistance, high strength, and high temperature resistance, and is suitable for connections in harsh environments, such as chemical equipment, marine engineering, outdoor facilities, etc., and can resist the erosion of seawater, acids, alkalis, and other substances.
– Carbon steel material: It has relatively high strength and a lower cost. Generally, it undergoes surface treatment to improve its corrosion resistance. It is often used in general machinery manufacturing, building structures, furniture assembly, and other occasions where there are higher requirements for strength but not particularly strict requirements for corrosion resistance.
The above are the common material classifications of open-end blind rivets in GB12618. In practical applications, appropriate materials of rivets can be selected according to specific requirements.https://pangjinfasteners.com/about-us.html
The surface treatment methods of open-end blind rivets specified in GB/T 12618 mainly include the following:
– Cadmium Plating: It can improve the corrosion resistance of the rivets, especially suitable for harsh industrial environments and marine environments. However, due to the toxicity of cadmium, its application is somewhat limited.
– Zinc Plating: This is a common surface treatment method that can form a protective film on the surface of the rivets, effectively preventing the rivets from rusting. It includes electro-galvanizing and hot-dip galvanizing, and hot-dip galvanizing usually has better corrosion resistance.
– Nickel Plating: Nickel plating can endow the surface of the rivets with good wear resistance and corrosion resistance. At the same time, it can also improve the appearance quality of the rivets, giving them a beautiful silver-white luster.
– Oxidation Treatment: For open-end blind rivets made of aluminum alloy materials, anodizing treatment is often adopted, which can form a hard, wear-resistant and corrosion-resistant oxide film on the surface of the rivets. Different colors can also be obtained through electrolytic coloring or dyeing processes to meet different decorative requirements.
1. About package
1.1 In our daily production operations, we always maintain a rigorous and scientific attitude towards the product packaging process. When it comes to selecting materials for the inner packaging of products, we typically use plastic films, plastic bags, or plastic trays. Thanks to their excellent sealing properties and corrosion resistance, these materials can effectively protect products and perform the functions of moisture prevention and rust prevention remarkably well. Especially for those fastener products with high manufacturing precision or those that are relatively fragile and vulnerable, we will additionally use cushioning materials with excellent shock absorption performance, such as foam plastics and sponges, to further enhance the protection. In this way, we can avoid product damage caused by various collisions and jolts during transportation, ensuring the integrity and quality of products to the greatest extent. Regarding the outer packaging, we usually choose corrugated cardboard boxes, wooden cases, or plywood cases. Corrugated cardboard boxes are lightweight and cost-effective, making them suitable for fasteners with relatively light weights. Wooden cases and plywood cases have high strength, which not only allows them to bear heavier loads but also enables them to meet the fumigation requirements for export packaging, making them ideal for heavy-duty or vulnerable fasteners.
1.2 In addition, we attach great importance to the personalized needs of each customer and are committed to providing customized packaging services. If customers have unique design requirements for the color, pattern, and size of the packaging, or if they expect to print exclusive brand logos on the packaging to enhance their brand image, we will go all out, mobilize various resources of the company, and make every effort to meet each special requirement of the customers. We strive to create unique packaging solutions for customers that are in line with their brand concepts and market positioning.
2.About payment
Our company uniformly adopts T/T (Telegraphic Transfer) as the payment method. For regular orders, a 30% advance payment is required at the time of placing the order to initiate the order process. The remaining 70% balance must be fully settled before the goods are loaded onto the vehicle to ensure a seamless connection between the payment transfer and the goods transportation process.
In the case of customized products, considering the particularity of their production, the advance payment proportion is adjusted to 30% - 50%, which needs to be paid upon finalizing the customized details and signing the contract. The remaining balance is also required to be paid off before the goods are loaded. Only when the balance is cleared can the goods be guaranteed to be delivered to your designated location on time and smoothly, avoiding any possible delays or disputes.
3.About Delivery & shipment
For in-stock products, with the support of our efficient logistics distribution system and internal coordination mechanism, we promise to complete the delivery within 10 days, enabling you to obtain the desired goods promptly. As for customized products, since they need to be produced according to specific specifications and requirements, involving multiple processes such as design confirmation, raw material procurement, and production, we will generally complete the delivery within one month, ensuring that you can receive the customized products that meet your needs as scheduled.
