At present, China generally uses ordinary brass as a raw material to produce copper inserts for meter boxes. In addition to ordinary brass, there is actually a lead-free environmentally friendly copper. This raw material is good in material, but the price is relatively expensive. It has not been popularized, and there are far fewer manufacturers using ordinary brass. In some European and American countries, it has been widely used. The components used in the copper inserts of the meter box produced by Ye Hao Electric are the more expensive but very good lead-free environmentally friendly copper, which is fully in line with the EU standards. The lead-free environmentally friendly copper is a copper material with a lead content of 50PPM.
The range of copper inserts for the meter box is very wide, on the casing of the TV or computer or on the meter box. Do you know why the copper inserts in the meter box are so common in our daily life? In fact, the reason is the characteristics of the copper inserts in the meter box. Because it is a copper insert, it is not easy to rust and is not easily corroded, and has very strong electrical and thermal conductivity. It is generally used in some specific occasions, such as faucets and valves, where anti-corrosion is needed, as well as various Various electrical switches and other places that require very good electrical conductivity. Where high temperature resistance, rust resistance, electrical conductivity, and thermal conductivity are required, copper inserts for the meter box can be used.
In addition to the direct use of the copper inserts in the meter box, the copper inserts in the meter box also have a major use in injection molding. After heating, it is embedded in the plastic part, or it is injection molded by the mold. Because the copper material is used, it has very good thermal conductivity. It is embedded in the heated copper insert. On the one hand, the copper material can quickly heat up to speed up the work efficiency. On the other hand, the copper insert has very good thermal conductivity. The heat can be quickly transferred to the plastic parts, so that the surroundings of the plastic parts will gradually become softer, which is more conducive to pressing into the holes.
Why use copper inserts instead of steel inserts? The reason is that the plastic will cool and harden very quickly after the copper nuts are injection molded. If the steel inserts are used, it will cause the high temperature after injection. The state will cause looseness or cracks around the plastic parts. Therefore, copper inserts are used instead of steel in injection molding.
There are two ways to form the knurling on the general surface of the copper insert of the meter box used in injection molding. The first knurling method uses copper material itself to be drawn and then produced on the equipment. The drawing pattern produced by this drawing method is straight, and the other method is used during the production process. Embossing while tapping, this kind of processing method can be used in some knurled copper and copper inserts that are not standard sizes. The shape of the copper insert of the meter box can be selected according to customer needs. The common knurled patterns are textured, embossed and other patterns.
The above introduces the materials and uses of the copper inserts of the meter box. To sum up, the raw material of the copper box inserts used by Ye Hao Electric is the relatively expensive but very good material. The characteristics of the parts and the use of the copper inserts of the meter box are very common, whether used independently or in injection molding.
