The key to cost reduction and efficiency improvement - Cost control strategies for knife plate spring pads and indentation strips

In the cost structure of packaging manufacturing enterprises, the expenditure on "consumable accessories" such as ejection rubber and creasing strips, although seemingly scattered, accumulates over a long period of time and accounts for a considerable proportion. Many enterprises often fall into the trap of "blindly choosing low-priced products" in cost control, which instead leads to a decline in product qualification rates and production efficiency, creating a vicious cycle of "the more you save, the more you spend". In fact, scientific cost control does not rely on low prices, but rather achieves the best balance between accessory costs and production efficiency through multiple strategies such as precise procurement, optimized usage, and recycling.

Precise procurement is the first line of defense in cost control, with the core lying in "selecting models based on demand and refusing excessive allocation". Some enterprises blindly pursue high-specification accessories when purchasing. For instance, they choose high-end wear-resistant spring pads in ordinary cardstock die-cutting. Although this extends the service life of the spring pads, it significantly increases the procurement cost. The correct approach is to match parameters based on production requirements - for production scenarios with small batches and multiple batches, cost-effective general-purpose knife plate spring pads can be selected. For large-scale and continuous production lines, high-end elastic pads with high wear resistance should be selected to reduce the total cost by extending the replacement cycle. The procurement of creasing strips is the same. For ordinary packaging of short-term orders, standard-sized creasing strips can be selected. For special products of long-term orders, although the single purchase cost of customized indentation strips is relatively high, it can avoid the increase in the scrap rate caused by size mismatch, and thus is more economical. In addition, establishing long-term cooperative relationships with suppliers and striving for price discounts through bulk purchasing, joint research and development, and other means are also effective ways to reduce procurement costs.

Optimizing usage and maintenance is the core link in reducing the consumption of accessories. During the production process, many parts wear out due to improper operation - for instance, excessive stretching of the spring pad of the knife plate during installation, and loose adhesion between the indentation strip and the knife plate, all of which will accelerate the aging of the parts. By standardizing the operation procedures and providing professional training for the operators, such unnecessary losses can be effectively reduced. At the same time, establishing a "tiered usage" system can also enhance the utilization rate of accessories: the elastic spring pads of the knife plates that have been replaced from the production line can be used in small-batch trial production or low-precision die-cutting scenarios; Use slightly worn creasing strips for creasing thinner paper to achieve "making the best use of everything". In addition, the scientific maintenance methods mentioned earlier, such as regular cleaning, timely inspection, and standardized storage, can extend the service life of accessories by more than 30%, directly reducing the frequency and cost of replacement.

Recycling and reprocessing add a new dimension to cost control. For repairable ejection rubber, their elasticity can be restored through professional repair techniques and they can be reused. The repair cost is only one-third of that of new parts. For irreparable elastic pads and indentation strips, some materials such as polyurethane can be recycled and regenerated. Enterprises can cooperate with professional recycling institutions to reduce the cost of waste disposal through resource recycling and obtain certain recycling profits at the same time. Through these diversified cost control strategies, enterprises can not only avoid the "low-price trap", but also achieve reasonable control of accessory costs, truly reaching the goal of cost reduction and efficiency improvement.
