Shenhua Printing Plate and Die Pad: Suitable for digital printing of short runs with fast turnaround, unlocking a new path for personalized packaging.

With the widespread adoption of digital printing technology and the explosive growth in personalized and customized demands by brands, the order structure in China's printing and packaging industry is undergoing a fundamental transformation. The production model that was previously dominated by large-scale production and long-term orders is rapidly shifting towards a short-order model featuring small batches, multiple batches, and quick delivery. Currently, over 60% of printing enterprises in China have a short-order business share exceeding 50%, and personalized customization and small-batch quick response have become the core development trends of the printing industry in the future.

However, the short-order quick-response model also brings significant challenges to printing enterprises: they need to change the die plate several times a day, and each change requires a lot of time for cutting, pasting, and adjusting the die plate spring pad. The effective production time is severely compressed; small-batch orders require frequent debugging, with a high waste rate, and profits are continuously diluted; traditional universal die plate spring pads cannot adapt to the flexible demands of the short-order quick-response model, becoming the core bottleneck for enterprises to seize the personalized packaging market. After 22 years of deep involvement in die-cutting consumables, Shenhua Impression has accurately grasped the industry's transformation trend and, in response to the core needs of digital printing short-order quick-response, has created an exclusive die plate spring pad product matrix and a flexible service system to help printing enterprises solve the pain points of short-order production and unlock the new path of personalized packaging.

Under the short-order quick-response model, the three core shortcomings of traditional die plate spring pads are magnified infinitely, becoming the core pain points of enterprise production. Firstly, the efficiency of changing die plates is extremely low, which is the core pain point of short-order production. Traditional universal spring pads are all supplied in whole rolls, requiring the machine operator to manually cut, shape, and paste according to the knife line, and repeatedly adjust the die-cutting pressure. Each die plate change takes at least 1-2 hours, and many enterprises spend more than half of their 8-hour working day on die plate debugging, resulting in less than half of the effective production time and a significantly extended order delivery cycle, completely unable to meet the requirements of short-order quick delivery.

Secondly, the waste rate of small-batch orders is high, and profits are severely diluted. The characteristic of short orders is small quantity and multiple types, and the machine operator does not have enough time to repeatedly debug, while traditional universal spring pads can only cover all materials and all processes with one product, requiring repeated trial cutting and adjustment, often adjusting the parameters before the order is quickly produced, and a large number of debugging products directly become waste. Many enterprises have a short-order waste rate even exceeding 15%, and the already meager profits are further eroded.

Thirdly, the waste of consumables is serious, and the overall cost remains high. Many enterprises, when facing small-batch orders, use one set of die plates with one new spring pad. After the order is completed, the used spring pad is directly discarded, and the waste of spring pads alone amounts to tens of thousands of yuan per year; at the same time, the back adhesive of traditional spring pads is mostly strong permanent glue, which cannot be completely removed and reused during die plate changes, further exacerbating the waste of consumables, and significantly increasing the cost of consumables for short-order production.

In response to the core pain points of the short-order quick-response model, Shenhua Impression has created a comprehensive solution from three dimensions: product design, production mode, and service system, completely solving the efficiency and cost problems of short-order production. In product design, Shenhua Impression has launched a fast-change die plate spring pad series, significantly shortening the die plate change time in two dimensions. One is the pre-segmented standardized spring pad, which is pre-cut into 2mm, 3mm, 5mm, 10mm and other width specifications, covering the 25-70 Shore A hardness range, and the machine operator does not need to manually cut, directly selects the corresponding width and hardness spring bar for pasting according to the knife line, reducing the cutting time by more than 80%; the second is the removable back adhesive design, using low-residue removable pressure-sensitive adhesive, during die plate change, it can be completely removed without leaving glue stains on the die plate, not affecting the secondary pasting use, significantly reducing the time for repeated pasting and debugging of the spring pad.

In response to the demand for customized replacement of irregular-shaped die plates, Shenhua Printing Materials has launched a pre-cutting customized cushion service. Customers only need to provide the die plate design drawings, and Shenhua Printing Materials can use laser precision micro-cutting technology to pre-cut completely matching irregular-shaped cushions according to the die line shape. Even for the most complex irregular die lines and fine hollow structures, 1:1 precise matching can be achieved. After receiving the cushions, customers can directly apply them on the machine without any secondary processing. The single replacement time is shortened from 1 hour to within 15 minutes. Even if there are 5 replacements per day, there will still be sufficient effective production time.

In terms of reducing waste rates, Shenhua Printing Materials has developed a universal material type die plate cushion. Through gradient hardness and balanced rebound formula design, it can simultaneously adapt to all types of substrates ranging from 80g thin paper to 5-layer corrugated paper. There is no need to frequently change the cushion model, significantly reducing the number of debugging times. At the same time, Shenhua Printing Materials has created a "Short Order Quick Anti-Padding Selection Manual" for short-order production, providing clear padding selection standards and die-cutting parameters suggestions for different materials and processes orders. The machine operator does not need to repeatedly try and make mistakes based on experience. They can directly select according to the manual. The first debugging pass rate can reach over 95%, reducing the short-order waste rate from over 15% to within 1%.

In terms of cost control of consumables, Shenhua Printing Materials has optimized the base material structure of the cushions. It uses high-density anti-deformation polyurethane base material. Even after multiple cycles of removal and reattachment, the cushion still maintains stable rebound performance, without deformation or collapse. This enables the cushions to be reused multiple times. At the same time, Shenhua Printing Materials has provided a short-order cushion reuse management plan for short-order production, guiding customers to classify and mark used cushions of different specifications and hardness. Categorized orders of the same specification and type can be directly reused. For partially worn cushions, only the damaged parts need to be replaced, without discarding the entire sheet. Through this solution, enterprises can reduce the cushion consumable cost of short orders by over 60%.

In addition, Shenhua Printing Materials has built a flexible intelligent production line that can achieve rapid delivery of small-batch customized cushions within 72 hours. Even for special specifications and special formulas of hundreds of meters of cushions, it can respond quickly. It perfectly meets the delivery requirements of short-order quick response.
