Discussion on plastic laser welding rivet technology - replacing traditional locking screws

With the rapid development of materials science and laser technology, plastic laser welding, as an advanced connection technology, plays an increasingly important role in the manufacturing industry. Especially in the fields of automobiles, electronics, and medical care, the demand for lightweight and high-performance plastic parts has led to the widespread application of plastic laser welding technology. Among them, plastic laser welding rivets, as an innovative connection method, combine the advantages of traditional riveting and laser welding, and provide a more reliable and efficient solution for the connection of complex structural parts. This article aims to deeply explore the technical principles, application advantages and development trends of plastic laser welding rivets.

1. Technical Principle

Plastic Laser WeldingRivet technology is a method of locally melting plastic materials through a laser heat source and embedding or forming a rivet-like structure in the melted area to achieve connection. Its basic principle can be summarized into four steps: laser heating, material melting, pressure molding, and cooling and solidification. First, the laser beam is focused on the plastic connection interface, generating high heat to rapidly heat up the local area of the plastic to above the melting point, thereby achieving melting of the material. Then, appropriate pressure is applied to the melted area, so that the melted plastic flows and forms a rivet-like structure under the guidance of the mold or fixture. Finally, after the plastic cools and solidifies, the connection process is completed.

2. Application Fields

Plastic laser welding rivet technology has been widely used in many fields due to its unique advantages. In automobile manufacturing, this technology can be used to connect body panels, interior parts, fuel tanks and other parts, which not only reduces the weight of the body, but also improves the connection strength and sealing performance. In the electronics field, plastic laser welding rivet technology can be used for the assembly of the shells of electronic products such as mobile phones and computers to achieve precise and beautiful connection effects. In addition, in the fields of medical equipment, aerospace, etc., this technology also shows broad application prospects.
