As an important material for post-press die-cutting, the indentation line has an important influence on the indentation and molding of the carton. How to distinguish the quality of the product, we teach you four tricks:
Identifying the carton indentation line has a move: the width and height error 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 not uniform, the precision is poor, and the error is very large. If the model is 0.5X1.5mm indentation line, according to the strict test of the laboratory, the width of the indentation groove of the inferior indentation line is actually 1.6mm-1.8mm, and the measured value is not in the range of 7.5mm. Inside. The quality of the same type of indentation line, the width of the indentation groove is 1,48mm~1.53mm, the error can be controlled within 2%. Another example is the height of the indentation groove. The measured value of the inferior indentation groove is 0.52mm~O. 55mm, the maximum error is 10%. The quality of the same type of product, the measured value of the indentation groove height is between 0.50mm - 0. 51mm, the error is completely controlled within 2%. It can be seen that the indentation groove of the inferior indentation line has a very large error, and it is easy to produce a series of quality problems.
Identifying the carton creasing line has a move type 2: material difference identification
Inferior products, in addition to poor precision, large errors, cut corners in many important parts, resulting in a decline in product quality. In order to seize market share, inferior creasing line manufacturers use cutting corners to reduce product costs, so that their products can enter the market at relatively low prices. For example, the width of the indentation line bottom mold, for example, the indentation line of type 0, 5x7.5mm, the bottom mold width of the inferior product is generally only 1.82mm, and the quality product reaches 2.5mm. The wider bottom mold width means a larger contact area, which helps the bottom mold to be more firmly attached to the spear die-cut base.
Another example is the tape that protects the bottom mold. The tape used in inferior products is even narrower than the bottom mold. The consequence is that some of the bottom molds have lost the protection of the protective glue before use, and it is easy to lose the viscosity when used. When the die-cutting machine is running at high speed, the bottom die is likely to fall out, causing damage to the die-cutting machine. The damage caused by downtime, machine maintenance, etc. will be even greater. The bottom mold protection tape of the high-quality indentation line can completely wrap the bottom mold, so that the entire bottom mold has strong adhesiveness when used, effectively avoiding the damage of the indentation line and causing damage to the machine, and also improving the precision of the die cutting. .
Identifying the carton creasing line has a move three: raw material identification
The high quality indentation line is produced with better quality raw materials and the product is more uniform. 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 the quality of the protective tape can meet the strict requirements, the high quality indentation line production factory does not purchase from the tape production factory, because the general tape is not suitable for the production of indentation lines, and the tape is The error range also does not meet the requirements. Therefore, the strong indentation line production plant will specially open a tape production line, specializing in the production of tape for creasing lines. The general indentation line production factory obviously does not have the strength to invest in a professional tape production line. It often buys ordinary tape from the market for the production of indentation lines, and the indentation line produced by using such materials. The quality can be imagined.
Identifying the carton creasing line has a move four: product development identification
High-quality indentation line production plants pay more attention to product research and development, while inferior creasing line production plants only focus on local interests. The lack of research and development has caused these inferior creasing line factories to lose the thrust of moving forward, but just wait for other manufacturers to develop newer products, and then slightly change their faces to plagiarize them, but they often know it because they don’t know why, but they get it. The product is not class. For the positioning strip of the indentation line, the indentation line of each size should be matched with the positioning strips of different sizes to ensure the complete alignment of the indentation line positioning. The general indentation line manufacturer does not necessarily find the mystery. All the indentation lines use the same type of positioning strip, so the use of the indentation line often causes inaccurate positioning and easy displacement. .
Inferior indentation lines can easily degrade the quality of the indentation and can easily cause great damage to the die-cutting machine. If the carton manufacturer purchases these inferior indentation lines, it seems to be cheap and can reduce the production cost. However, these products have low precision, large specification errors, and no guarantee of quality. On the contrary, they are likely to cause a decrease in production efficiency and uneven products. If the delivery is not timely, the customer returns, etc., the loss is even greater.
