Metal and plastic are two different types of materials. Generally speaking, plastic and metal cannot be fused together. However, there are ways to connect the two. Here are some ways to connect plastic and hardware.

①Use screw fastening method

By drilling holes on the surface of the material and then using fastener screws to fix the two materials, the effect of connecting the two materials, plastic and hardware, can be achieved. There are three commonly used screws, namely machine screws, ordinary self-tapping screws and triangular self-tapping screws. The use of machine screws requires processing threads on the hardware, or using threads for fastening; ordinary self-tapping screws are used for thinner sheet metal and aluminum parts, and softer hardware; triangular self-tapping screws are used for tapping holes on sheet metal parts.

②Use bonding method

Some plastics and hardware have relatively flat surfaces and can be connected by bonding. There are generally two ways of bonding. One is dispensing, which is also called glue coating, glue pouring, glue dripping, etc. It refers to applying, dripping, and pouring electronic glue, oil, or other liquids on the material to achieve the effect of adhesion.

③Use the buckle

A snap fit is a structure used to embed and connect one part with another, or to lock the whole part. It is usually used for connections on plastic parts and is widely used in many products.

④Use ultrasonic riveting

Ultrasonic riveting is a welding method of ultrasonic welding machine, which refers to the use of thermoplastics as rivets to penetrate another material to form the effect of welding two materials together. This connection method is widely used, and it will not affect the surface of the product, nor cause pollution. It can also be used for products with complex structures. Taking Zhaoqing ultrasonic apsonic ultrasonic welding machine as an example, the apsonic ultrasonic welding machine has a precision of up to 0.01mm and a welding speed of up to 0.6s, which can achieve high product output in a short time. The product welding quality is good, and the equipment will not affect the surface of the product under the appropriate welding method, nor will it affect the functional use of the product.

The above is the connection method between plastic and hardware. If you are interested in Zhaoqing Apsonic Ultrasonic, please call the company: 0756-8698786, or visit the company's official website: http://www.apsonicchina.com/. We are happy to serve you!
