Insert is a general term. In the mold, it refers to the irregular mold parts used in the mold, which plays a role in fixing the space between the template and filling the template.
Inserts can be square, round, or flat. Like all mold accessories, the precision requirements are very high. Generally there is no finished product, customized according to the needs of the mold.

In recent years, China’s social and economic and other undertakings have developed rapidly, and in particular, the process of urbanization has accelerated, and sanitation vehicles have developed rapidly. During the “Twelfth Five-Year Plan†period, 178 new special-purpose vehicle manufacturers (209-278 batches) were added. Some of the newly-added companies used environmental-protected vehicle products as the entry point for the enterprise's market competition, and have devoted themselves to this segment. According to statistics, from 2010 to October 2015, the number of manufacturers of special environmental sanitation products increased from 172 to 245.
According to the minister of the Technical Department of China Railway Vehicles Technical Service Center and professor-level senior engineer Gong Lei, the cumulative number of special vehicles for the four categories of vehicles (garbage, watering, cleaning, and sewage collection) in the period from January to October in 2015 was 47,981, a year-on-year decrease of 31.25. %, of which heavy, medium, light and mini vehicles accounted for 41.95%, 37.21%, 20.46% and 0.38%, respectively. Zoomlion, Hubei Chengli, Fujian Longma, Suizhou Dongzheng, and Hubei Heli together accounted for 41.2% of the total output of the industry.
Yan Lei said that the current policy direction of the government in the sanitation vehicle sector is to promote new energy vehicles. According to the "Notice on Continuing the Work of Promoting and Using New Energy Vehicles," government agencies, public agencies and other departments must lean toward new energy vehicles, and add new or updated public transport, official, logistics, and environmental sanitation vehicles to new energy vehicles. The proportion is not less than 30%. With the introduction of the government subsidy system, it also promoted the rise of the new energy sanitation vehicle market. By the end of 273 batches of announcements, the number of effective announcements for electric utility vehicles has reached 207. There are three categories of products, including garbage collection and transfer vehicles, excrement vehicles, and road surface cleaning vehicles, involving 19 models of 46 special-purpose vehicles. However, due to the lack of cruising range and lack of facilities such as charging piles, the procurement of new energy sanitation vehicles by the environmental and sanitation departments at this stage is not large, which is about 1% to 2% of the total.
In spite of this, Hao Lei is still optimistic about the prospects for the development of new energy sanitation vehicles. From January to October 2015, China's total production of pure electric garbage trucks was 301, and that of pure electric road sweepers was 120, both of which have significantly increased. 
In addition, Yan Lei also believes that with the change of government functions in the future, the sales target and model of Sanitation vehicles will change greatly. In the process of government decentralization, sanitation has turned to third parties in some areas, and the government has purchased services from third parties. In the future, a large number of environmental sanitation projects will be undertaken by sanitation vehicle manufacturers and third-party companies. At the same time, under the BT/BOT model, companies are required to change the single or small number of models in the product structure, to change to system product solutions, and to establish various integrated system solution modules in the sanitation sector. The way to change, while requiring companies to have a financial platform.
“Although there are more than 200 manufacturers, most of them are characterized by multiple, small, and scattered characteristics. There are 132 companies with an annual output of less than 100 vehicles, and the vicious competition and unregulated competition have shown obvious performance. Lei believes that the marginal contributions of many Sanitation trucks are generally not high, and they do not pay attention to technical inputs and market development. The production links are mostly hand-based. Most of the local governments in China are land finances. At present, under the condition of unsustainable land finance, many local governments are under pressure, forcing the government to shift to the market. With the transformation of government functions in the future, it is a great challenge for many special-purpose vehicle companies.
