Slotted sieve can be manufactured using different technologies. Each method has its own advantages and disadvantages. The choice of slotted sieve manufacturing method will depend on the desired request: mesh size, material and production volume.

Weaving

One of the most popular methods includes weaving. Weaving is a sieve manufacturing method in which wire mesh is woven in a specific pattern to create slots. Here, wire is used to make the sieve, which is woven together to form a mesh. The size and shape of the slits are determined by the thickness of the wire, the size of the weave and the weave pattern. This weaving method allows for the creation of high precision sieves with uniform slit sizes and shapes. It is used to produce slotted sieves with small slot sizes and stringent error standards.

Stamping

Another method of manufacturing slotted sieves is called stamping. Stamping is a method that manufactures perforated metal sieves by punching holes in a plate using a special die. The die is applied under pressure to the metal plate to make it take the desired mesh shape.

Stamping is one of the most efficient methods of manufacturing slotted sieves, as it allows for high accuracy in mesh size and shape. This method is also used to produce sieves with large size and high mesh density. It is suitable for high-volume production. However, there are limitations in the choice of material here: this method of slotted sieve manufacturing requires the use of certain metals that are suitable for punching the cells in it.

Electroplating

Galvanoplasty, also known as electroplating, is a process in which a layer of metal is applied to an electrically conductive surface using a current. In the context of making wire mesh sieves for sieving and filtering by applying a thin layer of metal to a metal base with a pattern. The advantage of using such a method is that it allows the creation of high-dimensional and precise mesh patterns, and this ability to endow metals with a special property such as corrosion resistance or high electrical conductivity. However, this process is a more expensive and labour intensive process compared to other methods of making slotted sieves.

Extrusion

Extrusion is a semi-automatic method for manufacturing slotted sieves. This method is used to produce plastic sieves with smaller mesh size. It is based on the use of an extruder, which forms the plastic mass into a tube, which is then cut into the required parts. The plastic mass used in extrusion must have good plasticity and hold its shape after cooling. Polymers such as PVC and PE are used as the material.

Extrusion can produce sieves with more accurate size and shape and also produce sieves with more uniform and accurate hole sizes, which can improve efficiency. However, these sieves are not designed for aggressive substances and materials and have a high wear rate.

Conclusion

In conclusion, there are many different methods for making slotted sieves. Each method has its own advantages and disadvantages and the choice of method will depend on the desired mesh size, material and production volume. It should be remembered that each of these methods has its own features and advantages, and the choice of method depends on the goals and requirements of the end result. It is important to look at factors such as accuracy, strength, durability, service life and efficiency when selecting a method of manufacturing slotted sieves.

The overall quality of the sieve is not only determined by the manufacturing method, but also by the material, texture and thickness.
