At present, the production of wiring terminals can be divided into two parts: plastic injection production and copper production. The finished terminals can be produced by assembly! In the process of plastic production, it is necessary to prevent impurities from entering, because impurities may affect the strength and insulation of insulating parts. How can impurities be avoided during the production of plastic terminal blocks? The following Zhuo Neng Xiaobian will introduce it to you!

Hazards of impurities mixed in the production process of terminal plastic?

Impurities in the plastic of the wiring terminal will affect the strength and various properties of the product, especially the metal powder, which will cause the product shell to conduct electricity and cause installation accidents!

Why are impurities mixed in the production process of terminal plastic?

1、 Impurities may come from the plastic raw material itself

Some manufacturers say that "we use brand-new materials without or impossible impurities". Is that true? This statement has its own problems. Manufacturers of plastic raw materials cannot guarantee that any batch of raw materials does not contain metal impurities! Even if it can do this, its manufacturing process and control process are very complex, and the price of the product must be very expensive. However, who can guarantee that the possibility of mixing metal impurities can be completely avoided in the subsequent transportation, use or processing process?

In fact, high-quality plastic granule raw materials only reduce the metal impurities in the plastic as much as possible, or to a level acceptable to users. So you need to be careful when purchasing materials.

2、 Processing of plastic raw materials

In the process of reprocessing (plastic modification, reuse after crushing, etc.), the following potential factors cause impurities to be mixed into the plastic:

1. Open containers shall be used for production and transportation;

2. Additives in granulating materials can also cause unqualified plastic parts;

3. Damage to fragments of crushing or grinding equipment;

How to avoid the entry of impurities during the production of plastic terminal blocks?

1. When purchasing raw materials, try to choose the original materials of the original factory, and do not be greedy for cheap;

2. In injection molding production, a powerful magnet can be installed in the barrel, which can effectively solve the suction of most of the metal.
