According to sources in the industry, the latest automobile tire pressure related regulations have entered the brewing stage and are expected to be launched soon. The new regulations set the mandatory standards for tire pressure, that is, automobile manufacturers must install tire pressure monitoring systems on vehicles in accordance with relevant requirements. The industry expects orders for automotive sensor companies to increase significantly.
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.

At present, China's tire pressure monitoring system mainly includes “direct tire pressure monitoring system†and “indirect tire pressure monitoring systemâ€. The direct tire pressure monitoring device uses a pressure sensor installed in each tire to directly measure the tire air pressure, and uses a wireless transmitter to send pressure information from the tire to the system on the central receiver module, and then to each tire pressure data. Conduct monitoring. When the tire pressure is too low or leaks, the system will automatically alarm. Even if the tires are slowly dispelled, the direct tire pressure monitoring system can be sensed by the driving computer, allowing the driver to directly inspect the tire pressure figures of the four tires from the driver's seat, thus real-time understanding of the real pressure condition of the wheels. The working principle of indirect tire pressure monitoring is that when the pressure of a tire is reduced, the weight of the vehicle will make the wheel's rolling radius smaller, resulting in faster rotation speed than other wheels, so that it can be used to compare tires. Speed ​​difference, to achieve the purpose of monitoring tire pressure.
Market analysts said that if tire pressure monitoring is implemented as a mandatory standard for automobiles, the demand for relevant sensor markets is expected to increase significantly, and the space for the automotive aftermarket is expected to open up. At present, the listed companies are Aerospace Electronics (February Research Reports), Feile Shares (Research Reports), AVIC Electric Measurement (Research Reports), Guoteng Electronics (Research Reports), Phoenix Optics (Research Reports), Tongfu Microelectronics Electricity (reports report), Silan Micro (marketing research report), Junsheng Electronics (marketing research report), Goer acoustics (research report), Hanwei Electronics (reports report) and other companies involved in automotive sensor business.
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.
