Clinching Machine

Model DFTL Clinching Machine

The Ductformer DFTL Series of Clinching Machine, made in St. Louis, MO, fastens two pieces of metal together via a Toggle Lock Fastening System. Toggle locking is the fastest and most cost-effective method to join two pieces of metal.

Benefits of Ductformer’s Clinching Machines:

  • Faster production: Clinching is significantly faster than welding or riveting, reducing overall production time and labor costs.
  • Cleaner process: No heat, sparks, or fumes mean a safer and more environmentally friendly work environment.
  • Material versatility: Clinching works with various materials, including pre-painted steel, galvanized steel, and aluminum.
  • Stronger joints: Clinched joints offer excellent strength and fatigue resistance, ideal for demanding applications.
  • Reduced damage: Clinching eliminates the risk of heat distortion or burn-through common in welding.
  • Cost-effective: Lower operating costs due to reduced energy use, no consumables, and minimal maintenance.


In the fast-paced world of metal fabrication, safety is paramount. When it comes to clinching machines, concerns about pinch points and powerful punches can arise. Ductformer, a leading manufacturer of metalworking machinery, addresses these concerns head-on with a range of safety features integrated into their clinching machines. Let’s delve into what makes these machines safer for operators and explore the technologies that empower confidence on the shop floor.

Low Down-Force Safety: A Built-in Guardian Angel

Ductformer’s clinching machines boast a unique low down-force safety feature as standard. This ingenious mechanism applies minimal pressure during the initial downstroke, increasing force only when the punch tool is less than 1/4″ form the full contact position. This crucial safeguard significantly reduces the risk of serious injury in case of accidental contact, offering peace of mind to operators and minimizing the potential for accidents.

Laser Precision: Guiding the Way to Accuracy

Another safety aspect lies in the integrated laser light locator. This feature precisely indicates the punch location on the workpiece, eliminating guesswork and ensuring accurate positioning of metal sheets. By minimizing the need for manual adjustments and close-up inspections, the laser light locator reduces the risk of operator error and potential injury.

Simplicity is Safety: Design for Ease of Use

Ductformer’s clinching machines prioritize user-friendliness. Their simple design minimizes the risk of operator confusion or misuse. Clear controls, intuitive operation, and readily accessible maintenance points contribute to a safer working environment. Additionally, the machines’ minimal use of air reduces the risk of pressure-related hazards, further enhancing overall safety.

Beyond Standard Features: Embracing a Culture of Safety

While Ductformer’s clinching machines offer robust safety features, the company emphasizes the importance of a comprehensive safety culture. They encourage users to:

  • Thoroughly read and understand the operator’s manual.
  • Wear appropriate personal protective equipment (PPE).
  • Never place hands or fingers near the punch area while the machine is operating.
  • Regularly inspect and maintain the machine according to manufacturer’s recommendations.

By combining advanced safety features with a commitment to user education, Ductformer empowers metal fabricators to work with confidence and efficiency. Our clinching machines are a testament to the fact that safety and productivity can go hand-in-hand, paving the way for a more secure and successful metalworking environment.

Remember, safety is not a feature; it’s a responsibility. Choose Ductformer’s clinching machines and embrace a culture of safety for a more productive and worry-free workshop.
