The C2A2 head combination is a modular head solution designed for multi-hole-position, multi-specification processing requirements, consisting of a coordinated dual punching module and dual tool holders: the two circular punching modules can simultaneously load punches of two different hole diameters, working with an oscillating knife and a bevel knife to complete contour cutting, and can be equipped with modules such as CCD vision components and inkjet heads as required by the process. This combination mainly addresses the efficiency bottleneck of multiple hole diameters on the same workpiece requiring separate clamping and repeated tool changes, enabling the full-process operation of punching and cutting in a single clamping.
Core Features
- Dual circular punches online simultaneously: The two punching modules can respectively load circular punches of different specifications, completing both hole diameters on the same workpiece in a single travel, eliminating the need for mid-process punch changes and secondary clamping.
- Dual tool holders for divided cutting: The two tool holders carry an oscillating knife and a bevel knife respectively; the oscillating knife handles conventional contour cutting, while the bevel knife handles cutting requirements with angles or special edges, reducing tool-change waiting.
- Full-sequence completion in a single clamping: Punching and cutting are performed continuously under the same datum, making the relative position accuracy of holes and contours more stable and avoiding cumulative deviation caused by multiple clampings.
- Modular configuration on demand: Modules such as tool holders, punching, spindle, CCD vision, and inkjet heads can be flexibly combined according to product processes; future capacity expansion or model changes can be upgraded module by module without replacing the entire machine.
- Vision and marking expandable: CCD vision components can be added for positioning and alignment, and combined with inkjet heads for marking or numbering, facilitating identification and traceability in subsequent processes.
Applicable Materials and Industries
This combination is suitable for processing sheet materials with dense hole positions and diverse hole diameter specifications, such as insoles, packaging backing boards, cardboard, honeycomb panels, EVA, foam, and some composite materials. Typical applications are concentrated in industries such as shoe materials and footwear supporting, packaging and printing post-press, automotive interior trim, and sports protective gear, and it is particularly suitable for order structures requiring grouped punching on the same layout followed by overall cutting.
Selection and Configuration Recommendations
If the product has more than two hole diameters, a large number of hole positions, and complex contour shapes, or if you wish to replace multi-process flow with a single setup, the C2A2 model is a more suitable choice; if only a single hole diameter or pure contour cutting is required, a more streamlined head configuration can be selected to control costs. In terms of supporting equipment, it can be linked with roll or sheet feeding platforms and automatic loading/unloading devices, and combined with layout and cutting software to achieve unified nesting of hole positions and contours, improving material utilization and overall cycle time.

In the footwear materials and packaging industries, multi-hole punching and contour cutting often need to be completed in separate operations, resulting in repeated clamping and tool changes. The C2A2 head combination integrates dual punching modules with dual knife holders, merging the two processes into a single setup and reducing positioning errors and auxiliary time. Tests show that for processing insoles with densely distributed holes, the cycle time per piece can be shortened by about 25%, while the positional accuracy of holes relative to the contour remains stable within ±0.1 mm, meeting the tolerance requirements of most mid-to-high-end products.
When selecting, it is necessary to evaluate the types of hole diameters and the batch size. If two or more hole diameters exist on the same layout and the contour is complex, the C2A2 model offers clear advantages; if there is only a single hole diameter or pure cutting, a single-punch single-knife configuration can be chosen to reduce costs. For supporting equipment, it is recommended to link with a roll-fed feeding platform or automatic loading/unloading device, and to combine nesting software to optimize hole and contour layout, which can improve material utilization by 10%-15%. In addition, CCD vision and inkjet heads are optional modules, allowing users to invest in stages according to traceability requirements.
For maintenance and upgrades, the C2A2 model adopts a modular structure; both the punching modules and knife holders can be independently removed and replaced, and routine maintenance only requires cleaning the guide rails and checking punch wear. When product changes require additional hole diameter specifications, it is only necessary to add the corresponding punching module without replacing the entire machine. The electrical interfaces use a standardized design and support quick plug-and-play, with single-module replacement time controllable within 15 minutes, effectively reducing downtime losses.
