Since the SMC is a fast curing system, the quick closing of the press is important. If the press is closed too slowly after feeding, it is easy to appear pre-cured patch on the surface of the product, or it may be short of material or oversized. While achieving rapid closure, the mold closing speed should be carefully adjusted at the end of the press stroke to slow down the closing process and facilitate the exhaust.
Molding Pressure The SMC forming pressure varies with the structure, shape, size, and degree of SMC thickening. The simple shape of the product requires only 25-30Mpa of molding pressure; the shape of the complex product, molding pressure can reach 140-210Mpa. The higher the degree of SMC thickening, the greater the molding pressure required.

According to the “Notice on Doing the 2011 Spring Fertilizer Supply Work†issued by the Development and Reform Commission, the Ministry of Industry and Information Technology, and the Ministry of Finance, in order to ease the cost pressure of chemical fertilizer companies and maintain the stable price of chemical fertilizers, electricity and natural gas for fertilizer production must be used everywhere. Continue to implement price concessions, continue to implement preferential tariffs on fertilizer rail transportation and exempt railway construction funds.
The "Notice" also requires all relevant departments to supervise enterprises such as power supply, gas supply and transportation to conscientiously implement the state's preferential policies for the fertilizer industry, and to resolutely correct the non-implementation of state preferential policies.
The circular also requires industrial and commercial administrations, quality inspections, and agricultural departments at all levels to intensify market supervision, severely crack down on illegal production and sale of counterfeit fertilizers, content of virtual targets, steal nutrients, and other violations of laws and regulations, and publicly expose major cases and cases.
The notice requires all localities to do a good job in the production and supply of chemical fertilizers in the spring, so as to guarantee the normal production and use of fertilizers by fertilizer companies and the supply of raw materials for chemical fertilizer production.
The size of the molding pressure is also related to the mold structure. The forming pressure required for the vertical parting structure mold is lower than that of the horizontal parting structure mold. A mold with a smaller gap requires a higher pressure than a mold with a larger gap.

China will continue to implement preferential policies for fertilizer production and distribution
The National Development and Reform Commission, the Ministry of Industry and Information Technology and other departments recently issued a notice requiring all localities to continue to implement preferential policies and prices for fertilizer production and distribution, and to maintain the basic stability of fertilizer prices.
