Shenhua Printing: Scientific storage and inventory management of die plate spring pads to prevent premature aging and waste

The knife plate elastic pads, as the frequently used and high-frequency consumables in printing enterprises, their storage and inventory management are often overlooked. Many enterprises randomly stack the elastic pads in the corners of the workshop or accumulate a large amount of inventory, which leads to premature aging, failure of the back adhesive, and permanent deformation of the elastic pads. This not only makes them unusable but also causes unnecessary waste. Moreover, it may lead to production stagnation due to the shortage of consumables. Deephua Printing, based on over ten years of industry experience, has compiled a comprehensive guide for the scientific storage and inventory management of knife plate elastic pads, helping enterprises standardize consumable management, avoid waste, and ensure stable production.

Improper storage methods are the main cause of premature failure of knife plate elastic pads. The core material of the elastic pads is synthetic rubber, which is extremely sensitive to temperature, humidity, light, and pressure. Long-term storage in a high-temperature environment will accelerate aging, causing hardening, cracking, and rebound failure; storage in a humid environment will cause the back adhesive to fail and the rubber to mold and deteriorate; long-term compression or bending storage will lead to permanent deformation of the elastic pads, making them unable to fit the knife plate smoothly; direct sunlight will damage the molecular structure of the rubber, accelerating aging and degradation. Additionally, mixing elastic pads of different specifications and hardnesses will cause inventory confusion and difficulty in access, affecting production efficiency.

Deephua Printing suggests that the scientific storage of knife plate elastic pads should follow the following five principles:

Environmental control principle: The storage environment should be kept dry, ventilated, cool, and shaded from light, with a temperature controlled at 5℃-30℃ and a relative humidity controlled at 40%-60%. It is strictly prohibited to store the elastic pads in open-air or damp basements, and to come into contact with corrosive substances such as acids, alkalis, organic solvents, and direct sunlight.

Flat storage principle: Unopened complete rolls of elastic pads should be placed vertically on the shelves, and it is strictly prohibited to lay them horizontally, stack them, or place heavy objects on top, to avoid deformation of the elastic pads due to pressure; after opening, the elastic pads should be resealed and stored flat, avoiding bending and twisting, and the remaining part should be promptly wrapped with cling film to prevent the back adhesive from failing due to moisture.

Classification identification principle: Elastic pads of different specifications, hardnesses, and batches should be stored separately, and clear labels should be attached, indicating product models, specifications, hardness, production date, and shelf life, etc., to facilitate access and first-in-first-out management. It is strictly prohibited to mix different models of elastic pads, to avoid incorrect access and production failures.

First-in-first-out principle: The shelf life of knife plate elastic pads is generally 12 months. Elastic pads beyond the shelf life will have their performance significantly reduced. Enterprises should strictly implement the inventory management system of first-in-first-out, using the elastic pads with earlier production dates first to avoid inventory accumulation leading to expired waste.

Safe inventory principle: Based on the production rhythm and order volume of the enterprise, a reasonable safe inventory should be set. Regular models should maintain a usage of 1-2 months, and during peak seasons, it can be appropriately increased to 3 months of usage. This avoids production stagnation due to consumable shortages. At the same time, it is not advisable to blindly prepare large quantities of inventory, which may lead to inventory expiration and waste.

To help enterprises manage inventory well, Deephua Printing provides comprehensive supporting services. Deephua has established a complete product traceability system, with each roll of elastic pads having a unique batch identifier, allowing for traceability of the entire production process. For long-term cooperative customers, it provides exclusive inventory custody services, preparing goods in advance and shipping as needed according to the customer's production plan, helping enterprises achieve zero inventory management. At the same time, Deephua will regularly remind customers of inventory status and product shelf life to avoid expired waste.

Scientific storage and inventory management not only extends the service life of knife plate elastic pads, reduces unnecessary waste, but also ensures the continuity and stability of production. Deephua Printing always takes customer needs as the core, not only providing high-quality knife plate elastic pad products, but also sharing professional consumable management experience to help enterprises achieve refined cost control.
