FULL AUTOMATIC MODE:
● AUTOMATIC
- This is the standard working cycle. The operator inserts the cabinet inside
the machine, pushes start button and waits until the cycle finished. The clamp pressure elements automatically open and eject the cabinet via conveyor.
REGULATION OF PRESSURE
● To regulate the vertical pressure, turn potentiometer VERTICAL FRAME at
anytime.
● To regulate the horizontal pressure, turn potentiometer HORIZONTAL FRAME at anytime.
Description of working cycle (standard machine):
● After you place the cabinet on the conveyor the cabinet moves into the clamp and the machine cycle begins.
At the same time, horizontal frame will descend and touch the cabinet
before ascending and positioning itself 1-2 cm from the top of the cabinet.
● The vertical frame moves the cabinet and begins to press the side of cabinet.
● After that the horizontal frame will press the cabinet from the top.
● The pressing starts with a low pressure and proceeds to the established
time and force of pressing.
● In case of electricity failure during the pressing, there is no risk because the
cabinet stays in position as the machine cannot move.
FEATURES:
● Heavy duty welded frame with CNC precision milling.
● 40mm diameter hardened guides that keep the pressing frames in true parallel.
● Lateral pressing bar gearbox with clutch for furniture protection
● Security devices with photocell on front and back side
● Dual pressing frames (horizontal & vertical) square the box to the fixed reference of the machine.
● Closing force is accomplished by a gearbox and steel reinforced tooth belt with dual pressing frames (horizontal & vertical)
● Patented double pulley traveler system. This traveler system quadruples motor power and transfers it to the pressing frame to ensure square closing of boxes with multiple fixed shelves. Power is adjustable to both horizontal and vertical pressers. This system is superior to pneumatic cylinders as Bonacin allows precise pressure regulation. It is faster than screw systems.
● Standard with loading conveyor and full automatic press and ejection
Specifications
BONACIN CLOSER 2500 Feed Through Case Clamp — Frequently Asked Questions
1. What is the BONACIN CLOSER 2500?
The BONACIN CLOSER 2500 is a feed-through case clamp designed for high-efficiency cabinet box assembly, allowing continuous loading and clamping of case goods in production environments.
2. How does the CLOSER 2500 differ from traditional case clamps?
Unlike stationary case clamps, the CLOSER 2500 uses a feed-through system that allows cabinets to move through the clamping cycle, increasing throughput and supporting continuous production workflows.
3. Who manufactures the CLOSER 2500?
The CLOSER 2500 is hand-built in Italy by Bonacin, a small family-owned manufacturer known for precision engineering and long-term mechanical durability.
4. What does the “2500” designation represent?
The 2500 designation refers to the machine’s maximum working length capacity, accommodating a wide range of cabinet box sizes.
5. What types of products can it assemble?
The CLOSER 2500 is designed for cabinet boxes, case goods, drawer carcasses, and rectangular assemblies used in residential and commercial cabinetry.
6. Why choose a feed-through case clamp?
A feed-through design improves assembly speed by allowing operators to load and unload cabinets efficiently while maintaining consistent clamping pressure.
7. How does it improve cabinet squareness?
The synchronized clamping system applies uniform pressure from multiple directions, ensuring consistent 90-degree alignment during glue curing.
8. Does it increase assembly throughput?
Yes. The feed-through format supports higher production rates compared to manual clamping or single-station case clamps.
9. Is the CLOSER 2500 suitable for high-volume cabinet shops?
Yes. It is designed for production environments requiring consistent, repeatable assembly cycles.
10. Can it be used in commercial millwork operations?
Absolutely. Its durability and precision make it suitable for both residential cabinet manufacturing and commercial casework production.
11. What materials can it assemble?
The CLOSER 2500 is suitable for plywood, MDF, particleboard, hardwood panels, and other common cabinet substrates.
12. How does it compare to manual bar clamping?
Manual bar clamping is slower, less consistent, and labor-intensive. The CLOSER 2500 automates pressure application, reduces labor time, and improves squareness accuracy.
13. Does it improve glue joint integrity?
Yes. Even, controlled pressure across all joints enhances glue bond strength and reduces the likelihood of joint gaps.
14. Is it compatible with dowel, confirmat, or cam-lock construction?
Yes. The machine is compatible with various cabinet construction methods, including dowel, confirmat screw, and cam-lock systems.
15. How does it support lean manufacturing?
By reducing bottlenecks in the assembly department and standardizing clamping cycles, the CLOSER 2500 improves takt time and production predictability.
16. Is the machine customizable?
Bonacin offers configuration options to suit different cabinet sizes and production layouts.
17. Is the CLOSER 2500 built for long-term durability?
Yes. As a hand-built Italian machine from a family-owned manufacturer, it is engineered for long-term industrial use.
18. What production advantage does feed-through clamping provide?
Feed-through clamping allows continuous part flow, reducing idle time between cycles and increasing total daily output.
19. Is installation complex?
Installation requirements vary by configuration and layout, but professional setup ensures optimal performance and alignment.
20. Is customer and technical support available?
Yes. Customer and technical support for the BONACIN CLOSER 2500 Feed Through Case Clamp is available through Centex Automation.
