The cost control code for creasing lines: The money-saving approach from "frequent replacement" to "long-term use"

For packaging manufacturers, although the procurement cost of creasing lines is not high, the "hidden costs" brought about by frequent replacement cannot be underestimated - the equipment downtime caused by replacing creasing lines, labor costs, and product defect losses due to untimely replacement often add up to several times the procurement cost. Many manufacturers fall into the trap of choosing low-priced creasing wires to save on procurement costs, but they end up spending more money due to frequent replacements. In fact, only by choosing the right creasing line and "extending its service life and reducing hidden costs" can one master the true cost control code.

Our high cost-performance creasing lines, through "material upgrade + process optimization", have reduced the overall usage cost from the source. In terms of material, the common carbon steel commonly used in low-cost indentation lines has been abandoned, and 20CrMnTi alloy steel has been adopted. The carbon content of this steel is precisely controlled between 0.18% and 0.24%, which not only ensures hardness but also has good toughness. After carburizing and quenching treatment, the surface hardness can reach HRC60-62 degrees The core hardness is maintained at HRC30-35 degrees, avoiding the problem of brittle cracking caused by excessive hardness. Comparative tests show that in the same corrugated paper creasing operation, the service life of ordinary carbon steel creasing lines is about 200,000 times, while the service life of our alloy creasing lines can reach 1.2 million times, which is six times that of ordinary products.

Process optimization further reduces hidden costs. Firstly, there is the precise cutting process, which adopts CNC laser cutting. The length tolerance of the indentation line is controlled within ±0.1mm. The cut edges at both ends are smooth and free of burrs. During installation, there is no need for secondary grinding; it can be directly connected to the indentation die. The installation time for a single indentation line is shortened from 15 minutes to 3 minutes. Calculated based on replacing 10 lines per day, it can save 2 hours of manual time. Secondly, there is the anti-sticking and wear-resistant coating process. A ceramic composite coating is sprayed on the surface of the creasing line, with a friction coefficient as low as 0.02. This not only reduces the friction loss with the cardboard but also avoids the blurring of the creasing caused by the adhesion of paper fibers, reduces the number of shutdowns due to cleaning paper fibers, and increases the effective operating time of the equipment by 15%.

Take a medium-sized packaging factory as an example. Previously, it used ordinary creasing lines, requiring the purchase of 120 each month, with a procurement cost of 3,600 yuan. The monthly downtime due to the replacement of creasing lines was approximately 8 hours, with a labor replacement cost of 1,600 yuan. The loss of defective products caused by creasing line issues was about 2,000 yuan, resulting in a comprehensive monthly cost of 7,200 yuan. After switching to our alloy creasing wire, only 20 pieces need to be purchased each month, with a procurement cost of 4,000 yuan. The downtime has been shortened to 1 hour, the labor cost is 200 yuan, and the scrap loss has been reduced to 300 yuan. The comprehensive monthly cost is only 4,500 yuan, saving 37.5% compared with the same period last year. Calculated on an annual basis, it can save 32,400 yuan in costs, truly achieving the goal of "spending a little and saving a lot".

To enable manufacturers to control costs more precisely, we have also launched a "usage calculation service" - based on the customer's daily output, processed materials, and equipment parameters, we accurately calculate the replacement cycle and purchase volume of the indentation line, avoiding capital occupation caused by excessive inventory and ensuring that production is not affected by insufficient inventory. In addition, for long-term cooperative clients, we also offer a "trade-in" service. Old creasing lines can be used to offset part of the procurement costs, further reducing procurement costs and making cost control more efficient.
