As an important protection product for mechanical parts, plastic rubber bushings for bolts are widely used in automobile manufacturing, construction engineering, aerospace, electronic equipment, home appliance manufacturing and many other fields. This article will be from the material selection, molding process, product characteristics, application areas and customized services in five aspects, a detailed discussion of the bolt plastic rubber sleeve knowledge.
1. Material selection
The main materials of the bolt plastic rubber sleeve include nylon, polypropylene, polyethylene and other high-strength plastic and rubber materials. The choice of these materials determines the corrosion resistance and high temperature resistance of the product.
Nylon: Nylon material has good elasticity and corrosion resistance, very suitable for use in harsh environments. For example, nylon protectors protect threads from abrasion or corrosion, keeping them clean and isolated from the outside environment.
Polypropylene: Polypropylene material has a long service life and toughness, and is resistant to acids and alkalis, protecting screws from the elements. Polypropylene protection sleeve is commonly used in a variety of construction machinery and mining hydraulic equipment protection.
Polyethylene: polyethylene material also has excellent abrasion resistance and anti-aging properties, commonly used in the manufacture of spiral plastic protective sleeve, instead of the traditional metal spring, the outer surface of the hose for anti-aging and anti-abrasion protection.
2.Molding process
Bolt plastic rubber sleeve molding process mainly includes injection molding, molding and so on.
Injection molding: injection molding is a granular or powdery raw materials added to the hopper of the injection molding machine, the raw material is heated and melted into a flow state, and then in the injection machine screw or piston drive, through the nozzle and the mold pouring system into the mold cavity, hardening and shaping in the mold cavity. Injection molding has a short molding cycle, high production efficiency, easy to realize the advantages of automation, suitable for mass production.
Molding: Molding is a certain amount of rubber material directly into the mold cavity, and then close the mold, through the pressure, heating and vulcanization process to get products. Molding is suitable for the manufacture of rubber bushings, especially thin-walled sleeve structure of rubber bushings, such as shaft precision products within the protective sleeve.
3.Product Characteristics
Bolt plastic rubber sleeve has a variety of excellent characteristics, making it an ideal choice for the protection of mechanical components.
Wear-resistant and corrosion-resistant: plastic rubber sleeve can effectively prevent threads from being abraded or corroded, prolonging the service life of threaded connectors.
Anti-aging: Plastic rubber bushings made of special materials, such as nylon and polyethylene, have good anti-aging properties and can be used for a long time in harsh environments.
Good sealing: the rubber sleeve can closely fit the threads, providing a good sealing effect, preventing moisture and dust from entering and keeping the interior clean.
Easy to install: The plastic rubber sleeve is easy and quick to install, no special tools are needed, just put it on the bolt.
4.Application areas
Plastic rubber sleeve for bolts has a wide range of applications, covering a variety of industries.
Automobile manufacturing: the automobile industry is one of the main application areas of the bolt plastic rubber sleeve. With the rise of new energy vehicles such as electric cars and smart cars, the demand for high-performance plastic rubber bushings for bolts will further increase.
Construction Engineering: In construction engineering, bolt plastic rubber bushings are often used to protect bolt connectors from corrosion and wear, ensuring the stability and safety of the building structure.
Aerospace: The aerospace industry has high requirements for plastic rubber bushings for bolts, requiring them to have excellent high temperature resistance, corrosion resistance and sealing performance.
Electronic equipment: In electronic equipment manufacturing, bolted plastic rubber bushings are used to protect bolted connections on circuit boards from dust and moisture.
Home Appliances: In the manufacture of home appliances, the bolt plastic rubber boot is often used to protect the bolted joints of home appliances to improve the durability and safety of the products.
5.Customized service
In order to meet the needs of different customers, bolt plastic rubber sleeve provides customized service.
Material customization: Customers can choose suitable materials according to specific application scenarios, such as nylon, polypropylene, polyethylene, etc., to meet different corrosion resistance and high temperature resistance requirements.
Size customization: Customers can provide specific size requirements, such as the diameter and length of the bolt, as well as the thickness of the rubber sleeve, etc., to ensure that the product can closely fit the bolt and provide good protection.
