The date stamp is a variety of words and patterns left on the plastic products, recording the production date, brand, trademark and service life of the plastic, so as to facilitate the quality management of the products. It is the main way to identify the future maintenance and service life of the products.
2. The date stamp can be divided into date stamp, month stamp, year stamp, year stamp, number stamp, environmental protection stamp, letter stamp, shift finger stamp, material stamp and other fonts and patterns. It can be combined with different specifications of product content to meet the needs of users. The date can be adjusted by simply rotating the shaft wheel.
3. For enterprises with strict management, each important plastic part should be marked with the production date, so as to determine the later maintenance or scrap date for televisions, cars, air conditioners, etc. Therefore, in order to facilitate future inspection, because the instability or mold repair changes in the injection process of plastic products will cause differences, the date stamp is added to distinguish the production date
