The price of raw materials is an important factor affecting the manufacturing cost of refrigerators. Since 2017, the prices of major raw materials for refrigerators such as PVC, polyurethane, hot-rolled steel and coking coal have risen to varying degrees. The rising cost of raw materials has led to an increase in the manufacturing cost of refrigerators, making the refrigerator market There is a clear trend of price increases.
The rise in refrigerator prices has made the development of the Chinese refrigerator market in 2018 less than expected. According to the national retail monitoring data of GfK China, the retail sales of the refrigerator in the second quarter of 2018 was the same as that of the same period in 2017. Under the environment of high average price growth, the retail volume showed a significant downward trend.
Different types of refrigerators are affected by the increase in cost. The low-end products of one or two doors and three doors have low gross profit margins, and the rising prices of raw materials have led to more obvious price increases. The multi-door and the door-to-door refrigerators are equipped with The richer product performance makes them have a larger premium space and is therefore less affected by fluctuations in raw material prices.
According to GfK China's national retail monitoring data, in the second quarter of 2018, the retail sales of each door of the refrigerator ranked the top 50 comparable models, the price of the refrigerator model increased compared with the second quarter of 2017 The proportion accounted for more than 50%. Among them, the price of one or two refrigerators increased the most, the number of models accounted for 82% of the door; the ratio of the number of models for multi-door and door-to-door products was 30%.
In the second quarter of 2017, the number of refrigerator models with a year-on-year increase was only 28%; the number of models for one or two refrigerators increased by only 57% in the door. Among these comparable models, a single model The most obvious increase was one or two refrigerators, the highest rose 22%, the three-door refrigerator rose 18%, the door-to-door refrigerator rose 11%, and the multi-door refrigerator rose 8%.
Under the cost pressure of rising raw material prices, the Matthew effect in the refrigerator market will become more apparent. Manufacturers must increase more technology investment and achieve more differentiation in the refrigerator to improve the competitiveness of their products, and to counter the impact of rising raw material prices by increasing the premium capacity of their products.
Plug-in Terminal Block
It is made of two parts of plug-in connection. One part compresses the wire and then plugs it into the other part, which is welded to PCB. The mechanical principle of the connection bottom and the anti vibration design ensure the long-term airtight connection of the product and the use reliability of the finished product. The two ends of the socket can be equipped with lugs, which can protect the lug to a large extent and prevent the poor arrangement of the lug.
At the same time, this kind of socket design can ensure that the socket can be inserted into the matrix correctly.
The socket can also have assembly and locking positions. The assembly buckle can play a more stable role in fixing to the PCB, and the lock buckle can lock the mother body and the socket after the installation. Various socket designs can be matched with different insertion methods of the parent, such as: horizontal, vertical or inclined to printed circuit board, etc., and different ways can be selected according to the requirements of customers. Either metric wire gauge or standard wire gauge can be selected, which is the most popular terminal type in the market at present.
