Why does traditional die-cutting always "drop the ball" when making game cards?
In the card production part of the printing industry, game cards and animation cards have shown that small batches and large batches can be produced, because the market demand is so diverse. This puts a lot of pressure on the flexibility of the die-cutting process. However, in this production environment, traditional die-cutting machines often have problems such as low efficiency and inconsistent quality, which are the main problems restricting the increase of production capacity. From a technical point of view, the "chain dropping" of traditional die-cutting machines is more common in these four major pain points.
First, the positioning is not accurate enough, and the finished product does not meet the standard. The edges of game cards must be much smoother than those of ordinary cards, and the patterns must be much more precise. Most traditional die-cutting machines use mechanical positioning, which is affected by material expansion and contraction, feeding errors, and other factors, and the positioning accuracy is difficult to guarantee. Actual production data shows that the position error is usually greater than ±0.5 mm when the traditional equipment die-cuts game cards. This can cause problems such as burrs on the edges of the cards and pattern offset. The scrap rate is usually between 8% and 12%. For small-batch orders, high scrap rates directly increase the production cost of each card, reducing the competitiveness of enterprises in the market.
2. Small batch orders are not flexible and take a long time to modify. Customized small-batch orders are the most popular type of game card orders at present. The traditional die-cutting equipment makes for a painful process of changing the mold and adjusting the machine. Changing a set of dies usually takes more than 30 minutes, and adjusting and proofreading the machine takes longer. There are even cases of "two hours of machine adjustment and ten minutes of production." This way of changing orders is not efficient, and the effective production time of the equipment is less than 40%, which cannot meet the production needs of multiple batches and fast turnover. Moreover, traditional machines mostly use metal molds, which are heavy and difficult to replace. The long production cycle and high cost make it more difficult to meet the production needs of small batch orders.
Third, the production process is scattered and the subsequent connection is not good. A standard die-cutting machine can only complete one die-cutting process at a time. After die-cutting, the finished products need to be picked up and sorted manually, and the waste needs to be cleaned manually. This process not only consumes a lot of labor costs but also easily leads to problems such as mixed materials of finished products and secondary damage. More importantly, traditional equipment cannot be connected to the packaging process at the back end, and semi-finished products need to be manually handled. This causes the production process to stagnate, making it difficult to improve overall production efficiency. Data shows that about 30% of the entire production cycle is spent on manual collection and collation of data. This is a big problem for improving efficiency.
Finally, the material has a small range of adaptation and poor process compatibility. There are many kinds of materials for making game cards, including paper, film, soft magnetic sheets, etc. The physical properties of different materials vary greatly, and the pressure and speed required for die cutting are also different. The power system and paper feeding mechanism of the traditional die-cutting machine are relatively rigid, and it is difficult to change them to meet the needs of different materials. When die-cutting special materials such as films and soft magnetic sheets, problems such as excessive indentation and material tearing often occur. At the same time, traditional die-cutting requires nail holes and connection points to be left on the product to ensure product positioning. This means that more trimming is required later, which makes the process more complicated and reduces the material utilization rate.
Three designs of high-precision game card die-cutting machines make it more efficient.
The design concept of the high-precision poker die-cutting machine is "short, flat, and fast," which solves the main problems of the traditional die-cutting machine. Through three major technological innovations, the production efficiency has achieved a great leap forward on the premise of ensuring the stability of product quality. The equipment is widely used in the production of various cards and small boxes, such as game cards, smart cards, business cards, playing cards, animation cards, and bank cards. It has three main parts that work together to improve efficiency: a precision positioning feeding system, a structure for quick order and mold changes, and integrated production optimization.
The first core design is the visual correction positioning of the layout and the stepping precision feeding system. This design solves the problem of inaccurate positioning of traditional equipment. The equipment has a high-definition visual detection module, which can see the positioning marks on the printing layout in real time and automatically change the feeding position by using intelligent algorithms. The correction accuracy can reach ±0.1 mm, ensuring that the die-cutting position is completely consistent with the printed pattern and the scrap rate is controlled below 2%. At the same time, the stepping feeding structure is adopted to decompose the whole feeding process into smaller and easier-to-control steps. The servo motor precisely controls each step, thereby controlling the speed and distance of the feed. This prevents the stretching and skewing problems that can occur with traditional continuous feed. This design is not only suitable for paper. It also works with materials of different properties, such as thin films and soft magnetic sheets. This makes the device compatible with a wider range of materials.
The second major design is that the machine can quickly change orders and adjust orders, as well as the wooden lightweight mold structure. The equipment has achieved a great leap in the efficiency of changing orders, meeting the needs of large and small batch production. The first step was to use lightweight wooden molds, which are 70% lighter than metal molds. Changing the mold does not require heavy tools and can be done by one person. Changing the mold takes only 2 to 3 minutes, saving more than 90% of the time compared with the old equipment. Second, the equipment has a built-in memory function for multiple sets of order parameters. The operator can set and save parameters such as die-cutting pressure, paper feeding speed, and correction settings for each order. When changing orders, you only need to call the correct parameters. The visual operation interface allows you to control the adjustment time within 15 minutes. This design increases the effective production time of the equipment to more than 85%, greatly improving the efficiency of small batch orders.
The third design is the full servo power drive and integrated production optimization. The power source of the equipment is a 7.5 kW servo motor. The response speed is faster and the power output is more stable than the traditional asynchronous motor. It not only stabilizes the die-cutting process and reduces burrs but also saves 30% of energy. The equipment integrates die cutting, waste removal, and finished product collection, optimizing the production process. The built-in negative pressure system can remove waste in real time during the die-cutting process, avoiding accumulation and affecting production. There are two modes for finished product collection: "sequential collection" is suitable for continuous production of standardized orders, and "classified collection" is suitable for mixed production orders of multiple specifications, without manual secondary sorting. More importantly, the equipment can be connected to the packaging equipment at the back end to form a fully automated production line from die-cutting to packaging. It completely solves the problem of segmentation of traditional production processes, making the overall production process more efficient. At the same time, the equipment adopts die-cutting technology, without nail mouths or connection points, which saves the trimming process and improves the material utilization rate by 10% to 15%.
Let's see: how much more efficient and less costly is your single card now?
For printing plants, the improvement of production efficiency will eventually lead to the reduction of costs and the increase of profits. We compare the production cost difference between traditional die-cutting equipment and high-precision game card die-cutting machines with the cost structure of the printing industry (paper cost, processing fee, labor cost, energy consumption cost, waste loss, etc.). We take a batch of 10,000 game card orders as an example to show the cost reduction brought by the efficiency improvement.
First, the basic figures are clear: the cost of paper is 0.1 yuan per sheet, the cost of die-cutting with traditional equipment is 0.05 yuan per sheet, and the cost of die-cutting with a high-precision game card die-cutting machine is 0.04 yuan per sheet. Traditional equipment requires two operators at 30 yuan per person per hour, while high-precision equipment requires one operator. The power consumption of traditional equipment is 20 kWh, the power consumption of high-precision equipment is 7.5 kWh, and the electricity fee is 1 yuan/kW·h. The defective rate of traditional equipment is 8%, and the defective rate of high-precision equipment is 2%. Traditional equipment requires 40 minutes for mold changing and adjustment, while high-precision equipment requires 18 minutes (2 minutes for mold changing and 15 minutes for adjustment).
When it comes to direct costs, the main differences are reflected in three aspects: labor, energy use, and waste loss. Labor costs: It takes 4 hours to produce 10,000 orders with traditional equipment, and the labor cost is 240 yuan (2×30×4=240 yuan), and the labor cost per card is 0.024 yuan. However, it only takes 1.3 hours for high-precision equipment to produce the same number of orders, with a labor cost of 39 yuan (1×30×1.3=39 yuan) and a cost of 0.0039 yuan per card. That is to say, each card saves 0.0201 yuan. The electricity cost of traditional equipment is 20×4×1=80 yuan, and the electricity cost of each card is 0.008 yuan. The electricity cost of high-precision equipment is 7.5×1.3×1=9.75 yuan, and the electricity cost per card is 0.000975 yuan. That is, each card saves 0.007025 yuan. Cost of waste loss: 800 waste cards from traditional equipment, loss of 800×0.1=80 yuan. The cost of each card is 0.008 yuan; the number of defective products of high-precision equipment is 200, and the cost of defective products is 200*0.1=20 yuan, so the cost of each card is saved by 0.006 yuan.
From the perspective of indirect costs, the improvement of the efficiency of order change saves a lot of time costs. It takes 40×9=360 minutes (9 times of order change) to complete 10 small batch orders of 10,000 sheets with traditional equipment, that is, 6 hours. The cost of equipment idling and workers waiting is 30×2×6=360 yuan. Using high-precision equipment, the total changeover time is 18×9=162 minutes, i.e., 2.7 hours, and the waiting cost is 30×1×2.7=81 yuan. This means a total saving of 279 yuan. Each card saves 0.0279 yuan per 10,000 orders.
The total cost of producing a playing card with a high-precision playing card die-cutting machine is 0.0201+0.007025+0.006+0.0279≈0.061 yuan less than the total cost of producing a playing card with old equipment. If a company produces an average of 1 million game cards per year, it can save 61,000 yuan per year. If 5 million cards are produced in a year, 305,000 yuan can be saved in a year. At the same time, the material utilization rate of the equipment increased by 10%. The average annual use of 50 tons of paper materials (unit price of 8,000 yuan/ton) can save 40,000 yuan of material costs each year, and the cost advantage is more obvious.
