1. Accuracy comparison: Flat knives are more precise, while round knives meet conventional requirements
In terms of precision, flat die cutting has more advantages. Because the flat knife is used for static pressing cutting, the material does not move, the mold and material are tightly adhered, and the cutting force is uniform. It can accurately control the size and flatness of each incision, even for complex irregular and small incisions, it can achieve accuracy and is suitable for high-precision scenarios such as die-cutting of electronic accessories and medical consumables.
The precision of round knife die-cutting belongs to the level of "as long as it is sufficient". Due to the rolling cutting process, there may be slight deviation of the material during transportation, and the centrifugal force during drum rotation may have a certain impact on the accuracy of small cuts. It is suitable for large-scale products with low precision requirements and standardization, such as ordinary packaging and adhesive labels.
Gaoqi strictly controls the accuracy of both flat and round die cutting. Flat dies are optimized for fine requirements, while round dies adjust the drum speed and feeding speed to ensure that each batch of products meets the customer's size requirements without deviation.
2. Efficiency comparison: Round blade crushes flat blade, preferred for mass production
In terms of efficiency, there is a significant difference between the two. The efficiency of circular cutting is 3-5 times that of flat cutting. Round knife is a continuous rolling cutting method that does not require any pause. It can feed, cut, and dispose of waste in one step, making it suitable for large-scale production. For example, if tens of thousands or hundreds of thousands of products are needed per day, choosing a round knife for die-cutting can greatly save time and improve production efficiency.
Flat blade die-cutting is a "single press, single cut" process that requires pausing, feeding, and retrieving each cut, resulting in relatively low efficiency. It is suitable for small batch and multi variety die-cutting needs, such as customers requiring small batch trial production and customized shaped products. Flat blade die-cutting is more flexible and does not require a large amount of mold and equipment costs.
3. Cost comparison: Flat knives have lower initial costs, while round knives are more cost-effective for bulk production
In terms of cost, there is no absolute high or low, the key depends on the production batch:
If it is a small batch with multiple varieties, choosing a flat knife for die-cutting is more cost-effective. Flat blade mold customization has low cost, short cycle, and relatively small equipment investment. Even small batch trial production will not cause cost waste, making it suitable for start-up enterprises and customers with small batch customization.
If it is large-scale and standardized, choosing a round knife for die-cutting is more cost-effective. Although the customization cost and equipment investment of round knife molds are higher than those of flat knives, in mass production, the efficiency is high and the labor cost is low. The cost of single piece die-cutting will be significantly reduced. The larger the batch size, the higher the cost-effectiveness, making it suitable for customers with stable large-scale demand.
Gaoqi will recommend the most suitable die-cutting process based on customers' batch requirements and precision requirements, helping customers control costs without wasting budget, while ensuring quality and efficiency.
