Prototype is a functional template which is made first according to the product appearance or structure drawings without opening the model to check the appearance or structure rationality.
Today, the development of domestic prototype industry has gone through a difficult process. Since 1977, with the vigorous development of China's machinery, electronics, light industry, instrumentation, transportation and other industrial sectors, there has been an increasing demand for casting dies in quantity, higher quality requirements and shorter supply period. Therefore, the relevant departments of our country attach great importance to the foundry model industry. They have listed the model as a key scientific research project, sent people abroad to study and investigate, introduced advanced technology of foreign foundry model, and formulated national standards for foundry model. Through these measures, the foundry die industry has made great progress, and some technical breakthroughs have been made. Second automobile manufacturing factory has adopted new technology and new materials to manufacture high-quality and large-scale foundry models for Japan's Isuzu Factory, which has won good international reputation.
With the increasingly fierce competition in the social market and the development of industrial design industry, enterprises attach importance to industrial design, but also pay attention to the production of product models. The development quality and actual effect of products need to be validated by prototype model. In this case, the prototype industry gradually separated from the industrial design process, and became a relatively independent industry and flourished. Many professional hand model companies have sprung up, and large-scale enterprises and industrial design companies have set up their own hand model departments. According to incomplete estimates, the number of prototype practitioners in China has reached 200,000, mainly distributed in the Yangtze River Delta, Pearl River Delta and Bohai Rim industrial developed areas, of which Shenzhen has more than 1,000 enterprises, and Shanghai has more than 200 enterprises. Prototype industry can be called the sunrise industry in the future. The development of the industry has its own advantages. Firstly, the social demand is large. The direct reason is the increase of enterprises' investment in product R&D, and the indirect reason is related to the development of domestic social economy. Secondly, the entry threshold of this industry is low, and the production plant and equipment that meet the production requirements can be built without a large amount of capital investment. Finally, the added value of this industry is relatively high, and the actual gross profit is much higher than that of the usual manufacturing industry, even higher than that of many design companies.
In recent years, prototype cluster production mode has been developed. There are more than 50 "prototype cities" in China. The built "prototype cities" play an active role. At the same time, they extend the industrial chain, reduce the cost of comprehensive operation, promote competition and cooperation within the cluster, and promote the formation of professional markets and production bases. Cluster production mode is not to attract more factories, but to share the platform and improve the production level together. In addition to the development support of hand panel cluster, hand panel industry has also trained a large number of elite talents, and is also moving towards precision in products, which will support more industries such as machine tool industry to refine.
