The main reason for the burrs on the lead-tin alloy badge is that during the production process, the pressure of the badge mold is uneven or the surface of the mold is uneven, resulting in the edges of the badge not being completely cut off and leaving some burrs. This situation

Not only does it affect the appearance and aesthetics of the badge, but it can also easily cause harm to the body, so it must be dealt with.

There are several main methods for handling burrs:

1. Grinding method: Use a grinding head to grind the rough edges flat, and then use a polishing machine to polish them to make their surface smooth. However, this method requires a high level of skill and experience from the machine operator.

2. Trimming method: Cut off the rough edges and maintain the integrity and original appearance of the badge while cutting, making its edges smooth.

3. Edge scraping method: Use a scraper to scrape off the rough edges, and then use a polishing machine to polish them to make their surface flat and smooth. This method is easy to operate and has obvious effects, but requires a certain level of craftsmanship.

4. Punching method: Using computer-assisted cutting machines for cutting, this method has the advantages of high work efficiency, correct designated parts, and easy operation.

In order to ensure the aesthetics and safety of badges, manufacturers should carry out quality control and testing work before, during, and after badge production to ensure that the badges are free of obvious defects such as burrs and fisheyes, and to ensure the quality of the badges produced

High, beautiful appearance. Meanwhile, corresponding measures should be taken for lead-tin alloy badges with defects such as burrs to avoid unnecessary harm to users.

In short, manufacturers should pay attention to quality control and testing as one of the important links in badge production, ensuring that the badge has a beautiful appearance and no defects such as burrs. The method of handling burrs should also be selected according to production conditions and needs

Choose a suitable method for processing to make the edges of the badge smooth and meet the requirements of safety and aesthetics.
