Cutting Technologies

Curvilinear Milling

Milling allows for precise cutting of any shapes from various materials, ensuring a smooth, matte edge surface. For clear plexiglass, diamond milling can be used to give the edges a mirror-like transparency effect. Milling is an excellent choice for projects requiring high precision and aesthetic finish.

Laser Cutting

Laser technology enables fast and precise cutting of shapes from many types of materials. The laser cutting process melts the edges, resulting in a transparent and glossy effect. Although the edge surface is not perfectly flat, slight irregularities add a distinctive visual effect.

Plotter Cutting

Plotter cutting is mainly used for materials such as self-adhesive films or thin cardboard. It allows for precise cutting of both simple and complex shapes in a short time. This method is ideal for projects requiring high repeatability and low production costs.

Guillotine or Knife Cutting

Traditional guillotine cutting provides a simple and economical processing method. Small marks and indentations may remain on the cutting edges, which can be easily removed using sandpaper. The option to smooth the edges allows for an aesthetic finish.

Summary:
Each cutting technology has its unique features that can be tailored to the specifics of the project. With wide technological capabilities, we can ensure precise and aesthetic processing of any material, meeting even the most demanding customer expectations.

Edges

Elements cut on the milling machine have sharp edges and remnants of the top layer of the material. Edge rounding and removal of remnants are the responsibility of the Customer - we recommend using sandpaper with a grit of 150-200.

The Kimla 1326 milling machine provides precise and versatile processing of various materials, making it an ideal solution for the advertising, industrial, and packaging production industries.

The process of edge polishing with a monocrystalline diamond blade on the Kimla machine applies to clear plexiglass and involves using a special diamond tool to achieve smooth, transparent edges after milling.

How is edge polishing done on the Kimla machine?

• Pre-processing - plexiglass is first milled to give it the desired shape.
• Diamond polishing - the diamond cutter performs additional edge processing, smoothing the surface and removing the matte finish that usually occurs after standard milling.
• Final effect - the edges achieve a high gloss and transparency, similar to the effect obtained by flame polishing plexiglass, but without the risk of thermal deformation.

Advantages of Diamond Polishing

• Achieving smooth, transparent edges without additional manual polishing.
• Greater precision and repeatability compared to flame polishing.
• No risk of overheating and material deformation, which can occur with thermal methods.
• Possibility of processing thicker plexiglass (e.g., 10 mm and more), where manual polishing would be more time-consuming.

Diamond polishing is an effective method, especially for high-quality plexiglass elements used in advertising and displays, where perfect finish and detail aesthetics are important.

Bending composite materials, such as Tu-Bond (DiBond), is performed by cutting a V-groove using a conical cutter. This process allows for precise bending of the panel without damaging the outer aluminum layers, ensuring an aesthetic and durable finish.

We also use Tu-Bond edge bending in the plaque and sign calculator. This is to stiffen the front surface and transform the flat panel into a spatial structure. This process increases the durability of the plaque and improves its aesthetics, eliminating the need for additional frames or reinforcements.

How does bending work on the milling machine?

• V-groove milling - the conical cutter removes the core layer to the appropriate depth, leaving only a thin layer of aluminum.
• Bending the material - after cutting, the panel can be manually bent along the milled line, achieving a clean and precise angle without the risk of cracking the outer aluminum layer.
• Edge stabilization - after bending, the structure increases its stiffness, and the bends remain stable, allowing the elements to be mounted without the need for additional reinforcement.

Advantages of Bending Tu-Bond (DiBond) with Conical Milling

• Precise execution - allows for obtaining perfect bending angles without damaging the outer coatings.
• Aesthetic finish - no visible cracks or deformations on the panel surface.
• Speed and repeatability - the process can be easily automated for larger production series.
• Versatility - method used in the production of advertising lightboxes, decorative panels, and exhibition systems.

Thanks to the use of a conical cutter, the Kimla milling machine allows for precise and repeatable bending of Tu-Bond (DiBond), making it an ideal solution for the advertising, construction, and industrial sectors.

Creasing/folding is a process that allows for aesthetic and precise folding of printed materials.

Folding

Machines:

• Eurofold two-cassette folder - two parallel folds on a sheet up to B3 format.

Media:

• Paper up to 170 g/m² (Eurofold) or over 200 g/m² (Duplo). The paper cannot be varnished or laminated.

Folding Formats:

• A4 - into 2 or 3 parts (letter "U" or "Z").
• A5 and smaller - in half.

Creasing

Machines:

• ANGRO 504 creaser - manual feeding.
• Duplo DC-445 - automatic creaser
• Duplo CF-375 - automatic creaser-folder.

Media:

• Cardboards from 200 g/m² and papers of any weight. The surface can be varnished or laminated.

Notes:

• We only perform parallel creases.
• Minimum distance from the edge: 50 mm, between creases: 40 mm.

Marking Creasing/Folding

Standard Products

• For products such as folded leaflets, folders, etc., creases are predefined, and the file should be prepared according to the dedicated template.
• Templates for individual products can be downloaded from the respective calculators.

Non-standard Works

For creasing, perforating, or folding non-standard projects (not defined in templates), you should:

• Add a detailed description of the crease location and folding direction in the comments when placing the order.
• Folding directions may include:
  • V - folding in half.
  • C - folding in "C - to the center".
  • Z - folding in "accordion".
• If possible, crease locations should be marked with a thin yellow line at the edge of the utility.

Exceptions for Plotter-cut Prints

• For works of any shapes cut by plotter, both creasing and cutting lines should be included on the project grid.
• Detailed guidelines can be found in the Help section: Cutting any shapes.

Perforation is a bookbinding process that involves making a series of small cuts along a line, allowing easy tearing of parts of a paper sheet. This solution allows for convenient separation of material fragments, such as coupons, forms, or tickets, without using scissors or cutting tools.

Machines

• Duplo DC-445 - allows for a maximum of 2 perforation lines on one sheet.

Media

• Paper with a weight of 200 to 350 g/m².

Notes

• Minimum distance of the perforation line from the edge of the sheet: 20 mm.
• Minimum distance between perforation lines: 40-45 mm.

Saddle stitching is a bookbinding method where paper sheets are folded and stapled with metal staples along the spine. This way of connecting pages is durable and aesthetic, and also allows easy opening of the brochure. Saddle stitching is ideal for thin brochures, guides, notebooks, and booklets.

Machine

• Duplo System 5000, two Duplo gathering towers + DBM spine shaping machine

Technology

• Stapling with regular or loop staples (for inserting brochures into binders).
• Maximum number of sheets stapled: 25 sheets of 80 g/m² offset paper.

Spine

• We profile (press) the spine of the brochure to be close to rectangular. Thanks to the profiled spine, brochures are flatter and do not open by themselves, which improves their aesthetics and functionality.
