High-precision bonding solutions for your industry

For 40 years now, Lohmann has been answering to increasing demands on the market. Customized, certified bonding solutions and high-precision die-cuts for applications in the fields of bio, process, sensor and medical technologies as well as automotive, electronics and consumer goods industries are developed with Lohmann’s “Smart-Bonding-Approach”:

From the initial idea to the final implementation into the customer’s process, the Bonding Engineers are competent partners at their customers’ side. Design and manufacturing are reconciled, if required by means of specially developed machines. Quality assurance, too, is essential to guarantee an error-free and smooth function. Geometrical, with tolerances in a micrometer range, as well as functional. During the entire production process Lohmann leaves nothing to chance.

The latest innovation is a state-of-the-art “laser-on-the-fly” process which allows for precise die-cuts roll-to-roll. Recently we accompanied this technology in the course an entire production process with the camera. Have a look for yourself and find out more about our comprehensive manufacturing possibilities.

  • Formats with lowest web widths
  • Unlimited format length
  • Smallest holes of 0.2 mm diameter and more are possible
  • Finest contours (channels, too) can now be implemented
  • Combination with die-cutting tools enables multilayering
  • Delivery form: on rolls or as individual parts

Flatbed

Flatbed die-cutting is one the two most frequently used die-cutting processes, with rotary die-cutting being the second one. Flatbeds are used for a wide range of materials, from lightweight ones such as paper to plastics and IML (In-Mould-Labeling). Flatbed die-cutters are used in particular for processing smaller quantities, for example in packaging and label production.

  • Sheet preparation
  • Especially suitable for small volumes in larger sizes
  • Preparation of sheet material for die-cutting cylinder
  • Inline lamination of jumbo rolls

 

Rotaries

Rotary die-cutting is one of the two standard die-cutting processes, with the second one being flatbed die-cutting. In this process, a cylindrical die rotates on a rotary press. Rotary die-cutting machines can include several stations with various functions that can all be synchronized into the same speed by geared tools to allow for low tolerances.

  • Different layers with different geometries
  • Inline measurements
  • Inline printing (ink jet)
  • Pre-treatment of materials (corona)

 

Prototyping via Laser Plotter

Laser plotters are widely used for prototyping, model and tool making. Because they can be applied to a wide range of materials, they are fit for testing new components and materials and developing prototype groups. Laser plotters work similarly to flatbed die-cutters, with their main functions being marking, cutting or engraving.

  • Laser plotter for sheet preparation
  • Prototyping & design verification, small volumes
  • Only few material restrictions

 

Full Metal Dies

One of the most widely used press systems are full metal dies. These electromechanically driven processing machines are characterized by the relative movement of their tools. Full metal dies are used in the die-cutting process for cutting, embossing or bending, often in short-stroke applications. The lifting force can be variably adjusted and tolerances are narrow.

  • Male/female dies
  • Very narrow tolerances

 

Site Remscheid

Lohmann’s Competence Center Die-Cutting in Remscheid was founded in 1972. Today, on an area of more 4.000 m² with about 130 employees, the site offers a wide range of converting machines: 16 rotaries (three in cleanrooms), three flatbeds, one full metal die, one central cylinder (in a cleanroom as well), a prototyping and an inline laser, state-of-the-art robotic and measuring devices, fully automated 100% measurement for running processes as well as cleanroom classes for pick & place processes.

Lohmann Remscheid has been certified many times over. Please click here, to find an overview of the certificates.
