Under the influence of new retail, electronic price tags have begun to be applied on a large scale. Electronic price tags mainly appear in supermarkets, convenience stores, pharmacies, 3C stores and other retail scenarios where there are many styles of goods and different price types, and the frequency of price changes is high.

The electronic price tag is an electronic display device that can replace the paper price tag. Its most basic function is to display the price information of the product.However, a good electronic price tag is not just as simple as displaying the price information of the product. Electronic price tags used in special areas also need to be waterproof.

For example, electronic price tags placed in the freezer area of ​​supermarkets need to be exposed to air conditioning for a long time. The electronic price tags here need to be waterproof, otherwise the electronic price tags will be easily damaged by water vapor.In the fresh food area of ​​supermarkets, water is generally used to feed fish, shrimp and other seafood products. Sometimes electronic price tags accidentally fall into the water.When the waterproof level of the electronic price tag reaches IP67, a brief immersion in 1M deep water will not cause harmful effects. Therefore, the waterproof level of the electronic price tag used in the fresh food area should preferably reach IP67.

The electronic price tag that Hai Ruisi made for the customer this timeAir tightness testing equipment, the tested waterproof level is IP67. Even if the electronic price tag accidentally falls into the water, just pick it up and wipe it dry. It will not affect the use of the electronic price tag.

It can be seen from the appearance of the product that the product tested this time does not have any inflation port. It is necessary to make a mold according to the shape of the product. By inflating the mold, the air pressure changes inside the mold are detected to determine whether there is leakage of the product in the mold.This method of testing the air tightness of the product through the mold is called indirect testing.

Hirays air tightness testing equipment is divided into air tightness testers and tooling fixtures. The tooling fixtures are mainly used to assist in completing air tightness testing, and their main function is to seal products.For test products that have an inflatable port, they can be directly tested through quick-cooking joints, and there is no need to make fixtures for testing.

After making a sealed tooling fixture for the product, you can connect the airtightness detector and the tooling fixture through the factory air source and start the airtightness test. For different products, the airtightness test data are also different. The IP67 waterproof test parameters of this electronic price tag are as follows: air intake time 5s, the test time is 5 seconds, the voltage stabilization time is 5 seconds, and the complete air tightness testing process of a product is 15 seconds. This is a single-station air tightness testing equipment. If you want higher testing efficiency, Hirays can also customize double-station, three-station and multi-station non-standard air tightness testing equipment for customers.Because the customer's test product has an IP67 waterproof level, the test pressure we use is 10kpa, the lower air intake limit is 9.5kpa, and the upper leakage limit is 0.05kpa. A test product must have an air inlet pressure of more than 9.5kpa and a leakage value of no more than 0.05kpa before the instrument will judge the product as a qualified product. Otherwise, the product will not meet the IP67 waterproof standard and the instrument will judge it as unqualified.

The electronic price tag I will share with you this timeAir tightness testing, belongs to electronic communication products. For electronic communication products, our company has the most waterproof testing equipment, and the technology is also the most mature. If your product needs to be waterproof, please call Hirays Technology, and we can bring your product to our company for air tightness testing.
