There are many methods of plastic molding. Injection molding is one of them. Injection molding is also called injection molding, which is called injection molding for short. It is a main molding method of thermoplastic. Because it has the advantages of wide application, short forming cycle, high production efficiency, good production conditions, easy mechanization and automation, it plays an important role in the whole plastic forming process.Injection molding refers to injecting granular or powdery plastic from the hopper of the injection machine into the high-temperature barrel, heating, melting and plasticizing to make it a flowing melt, and then under the high pressure of the plunger or screw of the injection machine, it passes through the nozzle at a large flow rate and is injected into the mold cavity. After a period of pressure maintaining, cooling and shaping, When the mold is opened, the Plastic Parts with certain shape and size can be detached from the mold cavity. In this way, the time required to complete an injection cycle can range from a few seconds to tens of seconds, which mainly depends on the size and thickness of the workpiece.

Raise seed germination virtual environment
There are many variables in the external environment. When germinating the seeds or other times, the variables in the natural environment directly affect the measurement results. Usually we will use a variable with less space to measure these times. We can use artificial climate boxes or smart artificial climate boxes to operate.
This artificial climate chamber is an intelligent micro computer artificial climate chamber control system of the FPID control mode developed by our company. It has temperature control (hot and cold temperature control), humidity control (humidification and dehumidification), and light control (with or without light ) And time program control (temperature, humidity, and light time program switching) and other functions. All technologies are in line with all requirements of the national industry standard JB/T 6823-93 "Technical conditions for biological artificial climate chambers." Its temperature control adopts FPID fuzzy control. It influences all factors that affect the growth chamber temperature such as ambient temperature, growth chamber set temperature, light intensity, and dehumidification conditions, etc., to participate in the temperature FPID adjustment, so that the temperature control quality is almost perfect. This technology is at the leading domestic level. At the same time, its moisture control system also uses FPID fuzzy control. It not only performs bit PID control according to humidity deviation on dehumidification and humidification, but also introduces the cooling condition into the humidity control system and also introduces the relationship between humidification and dehumidification to the moisture control system. Its power switch adopts three-phase air switch with leakage current protection, and is equipped with phase loss protection, compressor overload protection, and air blower overload protection.
Its planar structure is as follows:
