The creasing line of the carton is tied out by the mold and used to fold the carton into a shape. It refers to the line where the carton is folded. As an important material for post-press die-cutting, the carton creasing line is important for the creasing and forming of the carton Impact. The carton creasing line plays the role of facilitating folding, straight crease, beautiful appearance, and determining the outer size of the carton during the carton forming process. The crease standard can improve the compression resistance of the carton. Therefore, Changsha Packaging Carton Factory must choose the indentation line.
But if you want to get the perfect indentation, a high-quality indentation line is an indispensable helper. However, in today’s market, there are many low-quality indentation lines, which are shoddy. If each carton factory chooses inferior indentation lines, it is easy to cause the quality of the carton indentation to decrease, the production efficiency to decrease, and even the customer to return the goods. Bring great losses to manufacturers. Therefore, the correct selection of the indentation line and the identification of the pros and cons of the indentation line will help each manufacturer to create greater profits. How to distinguish the quality of the product, now from the following four aspects to distinguish the quality of the carton indentation line.
First, the width and height error discrimination of the indentation groove
Inferior indentation lines are mostly produced by small factories. These small factories generally do not have professional laboratories for product development and quality monitoring. Therefore, the products produced are uneven, with poor accuracy and large errors. For example, the model is 0.5X 1.5mm indentation line, according to strict laboratory tests, the indentation groove width of the inferior indentation line is actually 1.6mm-1.8mm, and the actual measured value is completely out of its standard value of 7.5mm. Within range. For high-quality indentation lines of the same model, the width of the indentation groove ranges from 1.48mm to 1.53mm, and the error can be controlled within 2%. Another example is the height of the indentation groove. The measured value of the indentation groove height of inferior quality is 0.52mm~O. 55mm, the maximum error reached 10%. For high-quality products of the same model, the measured value of the indentation groove height is between 0.50mm and 0.51mm, and the error is completely controlled within 2%. It can be seen that the indentation groove error of the inferior indentation line is very large, and it is easy to cause a series of quality problems.
Second, raw materials
The high-quality creasing line is produced with higher-quality raw materials, and the products are more uniform and consistent. The inferior indentation line uses inferior raw materials, which makes it difficult to improve the performance of the product. For example, the protective tape of the bottom mold, in order to ensure that the quality of the protective tape can meet the strict requirements, the high-quality indentation line manufacturer did not purchase from the tape manufacturer, because the general tape is not suitable for the production of the indentation line, and the quality of the tape The error range cannot meet the requirements. Therefore, the powerful creasing line production plant will set up a tape production line specially to produce the tape used in the creasing line. However, ordinary creasing line production plants obviously do not have the strength to invest in a professional tape production line. They often stock up ordinary tapes from the market for the production of creasing lines, and use such materials to produce creasing lines. The quality can be imagined.
