According to data released by the Korea Statistics Office on the 31st, the average operating rate of Korean manufacturing in July reached 84.8%, which was a 0.9% increase from the previous month. This is the highest level since the relevant statistics began in the 1980s. Data show that South Korea’s industrial production in July increased by 15.5% year-on-year and 1.1% month-on-month. In addition, the output value of the service industry increased by 3.4% year-on-year, and retail sales increased by 8.6% year-on-year. In addition, due to the record high manufacturing start-up rate in July, Korean companies’ investment in production facilities also increased significantly, with equipment investment increasing by 33.5%. According to the person in charge of the Ministry of Planning and Finance of South Korea, South Korea’s industrial production has exceeded the level before the economic crisis, trade conditions are good, domestic demand continues to expand, and South Korea’s recovery of the real economy is also relatively good. The overall economy of South Korea has entered a normal track.
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.

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.
