1. Self development
Sand casting is the basic industry of industry and has an irreplaceable position. From high-end industrial machinery and equipment, aerospace aircraft and marine equipment, to auto parts, engineering machinery and even daily necessities, many are related to. However, the traditional sand casting method is an industry with high labor intensity, bad working environment and great impact on environmental pollution. In recent years, with the rapid development of China’s economy, when ensuring the basic material needs, they began to favor the pursuit of spiritual needs, and began to pay attention to whether the working environment is conducive to physical health, whether the work they are engaged in has a certain technical content, etc. Young people pay more attention to the working environment when choosing a career. Therefore, the traditional sand mold foundry generally has the phenomena of shortage of employment, difficult recruitment, difficult retention and so on. Changing the traditional sand casting environment and improving the working environment of employees has become one of the common problems in the sand casting industry.
2. Product structure
At present, customized and personalized demand has become the mainstream of social development. The multi variety and small batch production mode has become more and more normalized. The demand driven supply mode has become the main way for enterprises to take the road of sustainable development. With the continuous rise of management costs, a large number of backlog and inventory will form a huge burden on enterprises, resulting in a sharp decline in capital utilization and a sharp decline in enterprise flexibility. Therefore, it is urgent to use emerging technologies to promote enterprise transformation and upgrading. As an industrial base, sand casting enterprises must transform rapidly to enhance their vitality and competitiveness.
3. Environmental protection policy
With the increasing awareness of ecological environment protection and the introduction of relevant environmental protection policies, sand casting industry has become one of the major industries concerned by the state and local governments. In response to the national policy, variousenterprises invest a lot of environmental protection equipment to control the existing pollution. This rectification method costs a lot of money, and belongs to the mode of pollution first and then treatment. For the traditional sand mold casting industry, it only plays the role of treating the symptoms rather than the root cause. The pursuit of clean sand mold casting and sustainable development is also the road that the sand mold casting industry must take.
