In the detection of seed germination rate, the use of advanced seed germination test equipment such as artificial climate incubators is an important prerequisite for obtaining correct and reliable germination test results. Therefore, it can be said that in the seed testing laboratories, the most essential instrument is artificial Climate incubator. The seed inspection test is the use of artificial climate incubators in the process, but also summed up a lot of experience in use, to grasp these experience for us to use good artificial climate incubators, do a good job in seed germination test has a very important help. Chemical Parts Investment Casting Chemical parts investment casting is one branch of alloy steel precision casting, which is widely used in chemical industry markets. Casting for chemical parts adopts lost wax casting, also called investment casting.
In wax pattern process,we mix stearic acid and paraffin wax. In wax pattern making, as you know, it is better than polyethylene, and the wax deformation is small. In dipping slurry process, most of the suppliers adopt water glass technics in domestic area,but we adopt compound technics or silica sol technics.
In shell making,we adopt automatic sand-covering production line, which was invented under the guidance of our general manager.The indoor temperature was controlled by air-conditions,keeping the temperature at 24℃±1℃, which can make the castings much more stable,the internal tissues much more well-proportioned.
In dewaxing process, about 95% of the castings suppliers adopt the original water dewaxing technics, but we using the advanced steam dewaxing technics, which we are very proud of.This can effectively avoid the air-hole and sand-hole,making the casting look much nicer.
In smelt process,we use middle frequency furnace,avoiding the emergence of the oxide; in molten steel control part, we use Germany-imported direct reading spectrometer machine,assuring its quality before the molten steel out of the furnace. During this process we use ERP production and management software to get the feedback information.
In heat treatment process, we use electric furnace,and adopt double-temperature control in order to heat the products equally. As a result, the products will have great metallurgical structure.
Our tolerance can reach at the grade of 5-7 according to our country`s tolerance standard.
In machining process, we have 12 CNC machining centers and some other machines, so we can make further machining if the customers need.
Our chemical parts investment cast has quality assurance in accordance with ISO9001: 2008, strict material inspection and exact dimension control, with 100% quality control. OEM order is welcome. The investment casting of chemical parts can be made completely based on your specifications such as drawing, design, sample etc.

1. Although the artificial climate incubator is a seed germination test device with very high precision, it can be used to simulate the natural ecological environment according to the germination needs of different kinds of seeds, but it should be noted that in the artificial climate incubator, the The temperature of each layer in the body is different, especially the incubator with a larger volume, this phenomenon is more obvious.
2. The selection of artificial climate incubators is also very particular. In general, artificial climate incubators have different models and specifications. There are many types of artificial climate incubators produced by Top Cloud Yunnong, and different models have different sizes and sizes. There are differences in functions, etc. Therefore, in order to perform the seed germination test, it is necessary to select the correct specifications of the artificial climate incubator. For example, we can select an artificial climate incubator with a small volume and a relatively uniform temperature for smaller experiments with smaller sample sizes or seed germination tests.
3. If precise seed germination tests are to be carried out, we suggest using precision seed germination boxes to carry out the work, so that the temperature and humidity in the housing can be guaranteed to the utmost, and in addition, thermometers can be used to calibrate the actual work. This can further reduce the gap between the set temperature and the actual temperature and improve the precision and accuracy of the seed germination test.
