PCR Plates, 96 Well PCR Plates, and 348 well plates are disposable consumables in the laboratory. They are widely used in genetics, biochemistry, immunology, medicine and other fields. They are not only used in basic research such as gene isolation, cloning and nucleic acid sequence analysis, but also Diagnosis of disease or any place where there is DNA or RNA.
The new line of white PCR products is designed specifically to optimize results when performing quantitative Real Time PCR (qPCR). The new 96 Well PCR plates are free of DNA, DNase, RNase, and other PCR inhibitors. 96 Well PCR plates have thin, uniform walls to ensure consistent, precise thermal transfer and excellent results.

From the perspective of worldwide observation of the development of China's manufacturing industry, it can be seen that China's manufacturing industry has developed rapidly in recent years. For the tool industry, this means a huge market. In this context, China's low level of manufacturing costs is a recognized fact. From the perspective of labor productivity, statistics show that compared with developed countries such as Germany, the United States, and Japan, the gap is about three to five times.
Such a large market, low levels of labor productivity, coupled with the continuous advancement and development of manufacturing technology, are both opportunities and challenges for the tool industry. The demand for tools in the market is not only the growth of quantity, but more importantly, the improvement of quality. From the perspective of the user industry, there are seven major industries that have the most demand for tools.
One is the power generation equipment manufacturing industry. In the context of global energy supply tensions and rising oil prices, the demand for power generation equipment has become more and more obvious. In the manufacturing process of power generation equipment, the cost of only the tool part is very considerable.
Mold manufacturing is also one of the industries with the largest tool consumption. In the mold manufacturing process, tools are required in almost all of the forming molds, hot molds, cold molds, and molds. In addition, automobiles, high-speed trains, general machinery manufacturing, and the wood processing industry, which has gradually expanded in recent years, have become major users of the tool industry.
The aerospace industry is the most traditional and important tool application area. In this industry, tools are commonly used to cut aircraft structural components. These structural members are generally bulky, and in the past a large number of aluminum alloys have been used. With the expansion of the application fields of titanium alloys and composite materials, the requirements for tool processing are becoming higher and higher.
As one of the key national support industries, in recent years, the government has invested a large amount of money for the research and development of large passenger aircraft in the aerospace industry. These R&D are all aspects. We take out the aspects related to the tool and analyze it, focusing on the use of structural materials.
As can be seen from the latest Boeing 787 fuselage, the method of directly covering aluminum alloys in the past has been gradually abandoned, and the direct laying and winding of composite materials has been replaced. In addition, the amount of titanium alloy is also increasing. Compared to the past, the new method can greatly reduce the weight of the aircraft, save fuel and energy consumption, which is especially important for large passenger aircraft.
Titanium alloys are recognized as difficult to machine materials. Composite materials that only need to be laid and entangled do not seem to require a large amount of processing, but the processing quality requirements are getting higher and higher. For the tool industry, this is no small challenge.
In addition to the fuselage structural components, the processing of aircraft engines is also a difficult point. The engine is generally made of difficult-to-machine materials, and has a complicated shape. It requires grooving, blade processing, etc., and the actual cutting effect of the tool is very high. In addition, in order to meet the high quality requirements of aircraft structural parts, in general, the whole blank is used for processing, and more than 90% of the materials will be cut off. Due to the large processing volume, the processing efficiency is extremely high.
