Indentation line as an important material for die cutting after printing, has an important impact on the indentation and molding of the carton. How to identify the quality of the product, we teach you four strokes:
Identifying the carton creasing line has a move: the width of the creasing groove and height error discrimination
Inferior indentation lines are mostly produced by small factories. These small factories generally do not have specialized laboratories for product R&D and quality control. As a result, the products produced are not uniform and have poor accuracy and errors. If the model is 0.5X 1.5mm indentation line, according to the laboratory strict test, the width of the indentation groove of the inferior quality indentation line is actually 1.6mm-1.8mm, and the actual measured value is not at its standard value of 7.5mm. Within range. The quality of the same type of indentation line, indentation groove width range of 1,48mm ~ 1.53mm, the error can be controlled within 2%. Another example is the height of the indentation trough, the measured value of the inferior indentation trough height is 0.52mm~O. 55mm, the maximum error reached 10%. For high-quality products of the same type, the measured height of the indentation groove is between 0.50mm and 0.51mm, and the error is completely controlled within 2%. It can be seen that the indentation groove of the inferior creasing line has a very large error and it is easy to produce a series of quality problems.
Identifying the carton indentation line moves two: the difference in the material
In addition to the poor accuracy and the large error, inferior products are still cutting corners at many important sites, resulting in a decline in product quality. In order to seize the market share, low-quality indentation line manufacturers use cutting-edge methods to reduce product costs, so that their products can enter the market at a relatively low price. For example, the width of the indentation line bottom mold is based on an indentation line of model number 0,5 x 7.5mm. For example, the bottom mold width of a poor quality product is generally only 1.82mm, while that of a high quality product reaches 2. 5mm. A wider width of the bottom mold means a larger contact area, which facilitates the bottom mold to be more firmly attached to the spear cutting base plate.
Another example is to protect the bottom mold tape. The tape used in inferior products is even narrower than the bottom mold. The consequence of this is that parts of the bottom mold have lost the protection of the protective rubber before use and can easily lose its viscosity when used. When the die-cutting machine runs at a high speed, the bottom mold easily falls out, resulting in damage to the die-cutting machine. Losses caused by downtime, machine maintenance, etc. will be even greater. The bottom mold protection tape of the high-quality indentation line can completely cover the bottom mold, so that the entire bottom mold has strong adhesiveness during use, effectively avoids the indentation line from falling off and causes damage to the machine, and at the same time, improves the accuracy of die cutting. .
Identifying cartons indentation line moves three: raw material identification
Quality indentation lines are produced with better quality raw materials and products are more uniform. The poor quality of the indentation line uses inferior raw materials and it is difficult to improve the performance of the product. If the protective tape of the bottom mold, in order to ensure that the quality of the protective tape can meet stringent requirements, the high-quality indentation line manufacturer has not purchased from the tape production plant because the general tape is not suitable for the production of the indentation line, and the adhesive tape The error range can not meet the requirements. Therefore, the strong indentation line manufacturer will specially open a tape production line to produce adhesive tapes for indentation lines. In general, indentation line manufacturers obviously do not have the strength to invest in a professional tape production line. They often store ordinary tapes for indentation line production from the market, and indentation lines produced using such materials. The quality can be imagined.
Identifying the carton creasing line moves four: product development and identification
Quality indentation line manufacturers pay more attention to product development, while inferior indentation line manufacturers only pay attention to local interests. The lack of research and development has caused these inferior indentation line production plants to lose their push for further progress. It is only waiting for other manufacturers to develop newer products and then plagiarize them with a slight change of face, but often it is because they know it but they do not know why, but it has made it worse. The product is neither fish nor fowl. Such as indentation line positioning strips, each size of the indentation line should use different sizes of positioning strips in order to ensure complete alignment of the indentation line positioning. The general indentation line manufacturer may not necessarily have the mystery of the pupil. All the indentation lines use the same specification of the positioning tape, so the indentation lines often appear to be misaligned and easily displaced. .
The poor quality of the indentation line can easily reduce the quality of the indentation, and it is also very easy to cause great damage to the die cutting machine. Carton manufacturers who purchase these inferior indentation lines seem to be cheaper and can reduce production costs. However, these products have low accuracy, large specification errors, and unqualified quality. On the contrary, they can easily cause a drop in production efficiency and products are not uniform. If the delivery is not timely, customers return, etc., the loss is greater.
As the old saying goes: If a worker wants to do good, he must first sharpen his tools. Choosing a good supplier and purchasing high-quality indentation lines can be your weapon to produce the perfect product.
