How to choose the vertical injection molding machine, because the vertical mold clamping vertical injection, the upper mold movable lower mold fixed. Straight-line injection molding machine is the most optimized solution for insert injection molding. The following are related to the purchase and classification of vertical injection molding machines. The most basic four elements of the injection molding machine are selected: 1. The modulus of the mold, the length*width* height of the mold, the specific specifications suitable for the mold of the factory product and slightly larger than the mold, which is the effective spacing in the Corinthian column. The amount is generally calculated as the plastic material PS in ounces (oz), because the PS density ratio is a vertical centimeter specific gravity of 1.05g, which is the conventional calculation unit. Different plastics have different structural density ratios, so the net weight of the product should be selected. The most effective injection volume of the injection molding machine is not more than 80% and not less than 20%. It is suitable for the model 3. Product accuracy, the precision of the plastic product. Directly related to the purchase and configuration requirements of the machine, for example, engineering plastics must use alloy screw and material tube, screw length to diameter ratio L / D more than 20 times, in order to achieve good plasticization standards and requirements. According to the precise requirements of the product, it is possible to use specific pressure + specific flow or semi-closed loop or full closed loop oil control. 4. The clamping force is the most important part of the injection molding surface. The clamping force is expressed in units per ton ( T), the standard for selecting the clamping force is the length*width of the plastic product* and the resistance of the plastic inside. Classification of vertical injection molding machines: Vertical injection molding machines can be divided into the following categories. First, the vertical injection molding machine series: This model is mainly for the injection line, all kinds of electronics, computer data lines and power plug wire injection molding, injection molding products are not required to meet the high precision standards, generally PVC, PE and other plastic materials injection molding As the mainstay, the specific applicable model specifications for this product generally range from 15T to 35T. Due to the specific modulus and configuration of each manufacturer's model, the manufacturer must be required before purchase. The factory determines the specific parameter specifications of the model. Second, the vertical horizontal injection molding machine, C-type injection molding machine series: the machine vertical mold clamping, horizontal injection rubber because there is no guide column, because the mold clamping part into an English letter "C" named. The machine is complex in structure and has a large amount of injection glue. Due to the wide working area of ​​the non-guide column, it is mainly suitable for injection molding of various types of safety power plugs, such as French head, American plug, British plug and so on. Third, vertical single slide type injection molding machine, double slide type injection molding machine series: This machine is mainly for engineering plastics, the products have strict precision requirements, precision or small inserts are injection molded together, and it is also optimized for insert injection molding. One of the molding schemes. Because the machine has the upper mold fixed, the lower mold slides out. The double slide type has an upper mold double lower mold, and the two molds alternate work, which is suitable for embedding or removing precision hardware. General molded products, such as electronic precision connectors, mobile phone connectors, integrated circuit components and other Atlas air compressor accessories. Fourth, vertical disc injection molding machine, rotary series: vertical disc injection molding machine rotary series can be described as the optimal solution for precision parts embedded injection molding, because the machine can design an upper mold two lower mold or multiple lower mold The function is more suitable for complex embedding and manual saving. Concerned about surprises Label: How to choose vertical injection molding machine Previous: Selection criteria for colony counters Next: Micro vacuum pump, micro air pump selection instructions Salinity sensors are used to measure the salinity (i.e. the amount of salt dissolved in water) in a liquid. They are commonly used in oceanography, hydrology, water quality monitoring, aquaculture and other fields. The Daruifuno DEC35 salinity sensor has a four-electrode structure, and the shell is made of titanium alloy, which is resistant to seawater corrosion.
In the farming industry, salinity probes are usually used together with dissolved oxygen probes, if you want to know about this combination, please contact us.

The salinity sensor has the following characteristics:
1. High precision: The salinity probe can provide high-precision measurement results to ensure the accuracy of the data.
2. High reliability: The salinity sensor is made of high-quality materials, which has high reliability and durability.
3. Easy to install and use: Salinity probe usually have a compact design and simple installation, and can be easily integrated into existing monitoring systems.
4. Real-time monitoring: The salinity sensor can provide real-time monitoring data to help users understand the changes in salinity in the liquid in time.
5. Cost saving: Using salinity electrode can reduce the cost and workload of manual monitoring and improve work efficiency.
