The main technology of precision plastic pepper ball welding is divided into five steps. Before precision welding of plastic products, the surface of the products to be welded should be cleaned, which directly affects the welding strength and precision of plastic products in the later stage. At present, the most commonly used method is ultrasonic cleaning of plastic products.

Plastic pepper ball products used for precision welding belong to the thermoplastic range, and the precision welding of thermoplastic products is mainly divided into the following steps:

The surface cleaning of plastic pepper ball products is mainly carried out by ultrasonic cleaning machine, which can clean the surface of plastic pepper ball products with special cleaning solution.

There are several methods to heat the welding surface of precision welding plastic pepper ball products, and laser heating and rotary heating are the main heating methods used in precision welding.

The two heated plastic pepper ball fittings are pressed together. There are several pressing methods, such as mechanical pressing, pneumatic pressing, hydraulic pressing and manual pressing. The pressing must be used together with corresponding tools to ensure that the two welding surfaces are welded together according to the set position.

Diffusion and welding, the melted part of the two plastic parts after pressure fuses with each other, and diffusion finally becomes a whole.Cooling and curing, the plastic parts after pressurization, diffusion and fusion are completely integrated after cooling and curing for a certain period of time. It should be noted that the two plastic parts should be continuously pressurized through the fixture during the whole process of cooling and curing until the cooling and curing is completed.
