Drip die is an important tool for manufacturing drip irrigation head. According to incomplete statistics, there are at least several hundred varieties of drip die on the market at present, and the manufacturing materials and technologies are also very different. For users who want to make their own dripper, it is very important to choose a suitable drip mold. However, for many users, how to choose their own drip mold is still a difficult problem. This article introduces to the user how to choose their own drip die.
1. Selection of drip irrigation system
Before choosing a drip mold, it is important to understand the drip irrigation system you are using. Currently, drip irrigation systems on the market are generally divided into three types: flat, continuous and line.
Flat drip irrigation system is generally used in ground drip irrigation, water outlet height is large, water flow is large; Continuous drip irrigation system is generally used in underground or top drip irrigation, uniform flow, can be very good control of drip flow; Split-line drip irrigation system is generally used in agricultural irrigation of trellis and glasshouse. The drip head and pipe are connected through connectors, which has a high leakage rate.
2. Selection of material
The material of the drip die has a great influence on the performance of the drip die, so it is necessary to choose the material carefully when choosing the drip die. The current market popular materials are ABS, PVC, PP and so on. ABS is a kind of polypropylene plastic, strong plasticity, good wear resistance, impact resistance, and relatively low price; PVC is polyvinyl chloride, has excellent chemical resistance and low temperature resistance, but the price is relatively high; PP is a type of polypropylene with high temperature and corrosion resistance.
Therefore, when choosing the drip mold, we should choose the right material according to our own needs, and do not blindly rely on the price.

3. Selection of dropper aperture
The aperture of the dropper is an important consideration in selecting the dropper mold. The choice of aperture depends on factors such as the flow rate of the droplet, the environment and the plants. If the aperture is too small, it will slow down the drip rate and lead to poor irrigation effect. If the aperture is too large, the water flow will increase accordingly, which is not conducive to saving water.
Therefore, when choosing the drip die, we should rationally match it according to our own needs and drip irrigation system, and choose the right aperture. Generally speaking, under the conditions of centralized water supply and same spacing for common public drip irrigation, the drip head with aperture of 0.8~2.0mm is a better choice.
4. Selection of drip exit Angle
The larger the exit Angle of the drip head, the farther away from the ground the water will be, and the greater the possibility of water interfering with each other. Therefore, the exit Angle is also one of the important factors to consider when selecting the drip die. Generally speaking, the dropper with an exit Angle of about 70 degrees is a more appropriate choice.
5. Choice of brand and quality
Brand and quality should also be taken into consideration when selecting the drip mold. Choose the brand with good reputation to ensure the quality and performance of the product. After all, the quality of raw materials, manufacturing process and technical level all determine the quality and performance of the dropper.
In a word, it is a matter of discretion to choose the drip mold suitable for yourself. It is necessary to have a deep understanding of the nozzle aperture, exit Angle and drip irrigation system that you need, and understand the material and brand quality of the drip mold. In this way, the appropriate drip mold can be selected to better irrigation, improve crop yield and ensure farmers' income.
