In these aspects, the water purification effect of the water filter can be optimized and the life can be longer. However, in real life, the Water Filter Spare Parts(KOKOELECTRIC) https://www.kokoelectric.com/
are inevitably encountered some common faults. What should I do? Please ask the master to repair the door? Actually, it is not necessary, some common glitch, sometimes we only need to do it ourselves. He repaired it well, of course, this requires us to understand some of this knowledge.
1. The new machine has a smell of water
After the water filter is installed, the water filter should be rinsed first, and the correct flushing method ensures the normal use in the later period. If the flushing sequence is wrong, more problems will occur, especially for the water purification. If the washing sequence of the ultrafiltration... less

manufacturing, there are many factors that affect the quality of the mould. Mold design, mold processing, mold assembly and debugging are all the key factors that affect the final quality of the mould. Furniture mold design is the most critical link that determines the inherent quality of the mold. The quality of furniture mold and product directly depends on the quality of mold process design and structure design. Designers should not only consider meeting customer's requirements but also consider the machinability, reliability, maintainability, convenience, safety and service life of furniture mould.
The furniture mold processing process is also an important part to ensure the quality of the mold. The processing method and precision in the furniture mold manufacturing process will affect the service life of the mold. The machining accuracy of furniture mold parts directly affects the overall assembly quality of the... less

If the market supply does not meet the demand, it will affect the price of metal materials, which will lead to market confusion. The application of Copper Clad Aluminum Winding Wire(XINYU) http://www.xinyu-enameledwire.com/product/enameled-rectangular-copperaluminum-wire/
in our lives can be said to be very extensive, but there is also the safe existence of copper clad aluminum winding wire.
With the continued growth of copper consumption, the lack of copper resources in China, the market demand for metal materials has improved. However, in recent years, due to the rapid increase in copper prices, products in the cable market have experienced unqualified cable diameters, unqualified cross-sectional areas, and the use of hybrid copper counterfeit products. With the emergence of these counterfeit and shoddy products, the normal order of the market has been disrupted. In the case of national regulations, the aluminum wire should not... less

It uses charcoal, bamboo charcoal, various shells, and high-quality coal as raw materials to crushing, sieving, catalyst activation, rinsing, drying and screening of raw materials through physical and chemical methods. It is manufactured by a series of processes. It has the dual characteristics of physical adsorption and chemical adsorption. It can selectively adsorb various substances in tap water to achieve decolorization, deodorization, chemical pollution removal, and volatile organic compounds. Do you know how important activated carbon is in the Water Filter Spare Parts(KOKOELECTRIC) https://www.kokoelectric.com/
?
When buying a water filter, you will always hear or see "activated carbon". Whether it is ultrafiltration, reverse osmosis or nanofiltration, the key technology has changed, but the constant is always activated carbon. It can be seen that activated carbon is very important. The common types of activated carbon are as... less
(1) Requirements for injection molding materials Different plastics should be selected from different materials such as high polishing requirements and corrosion resistance requirements;
(2) Heat treatment. The surface treatment of household product mould is also very important. Nitriding - can enhance the surface hardness of steel, effectively extend the life of the mold; electroplating - can effectively modify the mold steel, for some high-brightness and corrosion-resistant plastic parts can use electroplating to enhance and improve the performance of steel.
2. Mold processing
The arrangement of the mold process is particularly important, and the reasonable process arrangement can speed up the production cycle, shorten the processing time, and... less
