Precision seed germination box for precise control of environmental conditions

We know that in order to successfully germinate the seeds, in addition to the seed itself has a sound germination power and the release of dormancy, it must also have certain external environmental conditions to support, so the external environmental conditions have a great impact on seed germination. In order to accurately determine the germination of seeds, we need to provide constant environmental conditions for seed germination to avoid the impact of environmental changes on the test results. The precision seed germination box can achieve fine environmental regulation and provide ideal and stable environmental conditions for different seed germination.

Temperature, humidity, and illumination are important environmental parameters for the germination of the impression seeds. Therefore, the precise control of the precision seed germination box is the three major environmental conditions. The temperature mainly affects the swelling rate of the seed, the respiratory intensity, and the activity of various enzymes or the hydrolysis, transportation and synthesis of the stored substances, thereby affecting the speed of seed germination. Therefore, the precision seed germination box is used to create the humidity, temperature, etc. suitable for seed germination. Conditions can promote seed germination, increase seed germination rate, shorten experimental time, improve experimental efficiency and experimental results.

Qualified commercial seeds generally have a high germination rate. For example, the germination rate of qualified commercial wheat seeds is generally 90% to 95%. High germination rate is an important indicator for measuring seed quality and an important guarantee for crop growth. Therefore, with the acceleration of the process of seed commercialization, seed germination experiments are becoming more and more frequent. The precision seed germination box utilizes powerful program control ability, and can arbitrarily set the temperature, humidity and illuminance within the range according to the experimental needs. It not only satisfies the basic environmental conditions of the experiment such as the determination of the germination rate of the seed, but also facilitates the operation by simplifying the process. Intelligent management has also greatly reduced the threshold of germination experiments, improved the efficiency and accuracy of seed germination experiments, and provided an important force for the development of seed commodification, ensuring the quality and safety of seeds.

Die Casting

The Die Castings that are created in this process can vary greatly in size and weight, ranging from a couple ounces to 100 pounds. One common application of die cast parts are housings - thin-walled enclosures, often requiring many ribs and bosses on the interior. Metal housings for a variety of appliances and equipment are often die cast. Several automobile components are also manufactured using die casting, including pistons, cylinder heads, and engine blocks. Other common die cast parts include propellers, gears, bushings, pumps, and Valves.

Die casting is a manufacturing process that can produce geometrically complex metal parts through the use of reusable molds, called dies. The die casting process involves the use of a furnace, metal, die casting machine, and die. The metal, typically a non-ferrous alloy such as aluminum or zinc, is melted in the furnace and then injected into the dies in the die casting machine. There are two main types of die casting machines - hot chamber machines (used for alloys with low melting temperatures, such as zinc) and cold chamber machines (used for alloys with high melting temperatures, such as aluminum). The differences between these machines will be detailed in the sections on equipment and tooling. However, in both machines, after the molten metal is injected into the dies, it rapidly cools and solidifies into the final part, called the casting. The steps in this process are described in greater detail in the next section.


Die cast parts can vary greatly in size and therefore require these measures to cover a very large range. As a result, die casting machines are designed to each accommodate a small range of this larger spectrum of values. Sample specifications for several different hot chamber and cold chamber die casting machines are given below.

The selection of a material for die casting is based upon several factors including the density, melting point, strength, corrosion resistance, and cost. The material may also affect the part design. For example, the use of zinc, which is a highly ductile metal, can allow for thinner walls and a better surface finish than many other alloys. The material not only determines the properties of the final casting, but also impacts the machine and tooling. Materials with low melting temperatures, such as zinc alloys, can be die cast in a hot chamber machine. However, materials with a higher melting temperature, such as aluminum and copper alloys, require the use of cold chamber machine. The melting temperature also affects the tooling, as a higher temperature will have a greater adverse effect on the life of the dies.
