Services with laser
Laser Nova use lasertechnology for cutting, welding, engraving and drilling.
Laserwork in really small dimensions
We use laser technology for cutting, welding, engraving and drilling. Much of what we do is welding, but cutting is also a large part of our production.
Lasers have properties that make them perfectly suited for work in tiny dimensions. We can cut complex geometries and make cuts as narrow as 0,015 mm wide. We also laser drill holes that are invisible to the eye, and weld joints as small as a few tenths of a millimetre in width.
One of the major advantages of using lasers is that you can quickly and simply create a prototype of a tool, for example, that can be mass produced at a later time. That means that several different geometries can be tested quickly and cost-effectively.
This allows us to take on projects that other technologies can't manage. And we can do this for sectors that require high standards of accuracy and precision. We also know that laser processing offers unique flexibility as it's often cheaper and faster than other techniques.
All our work is carried out using YAG lasers and CO2 lasers, including:
- Cutting
- Welding
- Drilling
- Engraving
- Surface structuring
We can also offer lathing and milling services. We can analyse our processes using a high-speed camera and carry out post-production analysis using a scanning electron microscope (SEM analysis). This allows us to study everything we do in detail and ensure the correct process is in place at an early stage.
We are quality certified according to ISO9001:2015 och ISO 13485 medical devices and approved by the American FDA.
Process areas:
- Research and development
- Prototyping
- Planning and project managment
- Production planning and production
- Design
- End-to-end prosses solution
We will help you find the technical solutions you need
The earlier we become part of your product development process the better. Working closely with your product development team and your design engineers we ensure the best, most efficient and cost-effective production for your product.
Cutting
Laser Nova works with cutting anything from the thinnest foils to materials that are up to 5 mm thick. Our finished products are often tiny micro-components that require the utmost precision.
We handle a wide range of materials. Most commonly, we work with stainless steel, titanium, tungsten, carbon steel, ceramics, aluminium and copper.
Complex cuts and narrow radii
Our lasers give a very narrow kerf and a fine, clean cut that often doesn't require any subsequent work. They can also manage complex geometries, narrow radii or very thin sections. One area where we often use this technique is in manufacturing surgical tools.
Welding
By far the greatest expertise we have is in welding - in tiny formats. A laser's unique properties make it a perfect tool for welding.
The laser's high power density provides a deep and narrow weld with a minimum heat-affected zone. This means adjacent areas don't risk being damaged and results in no or minimal deformities.
This technique is used both in precision engineering and when welding close to heat-sensitive electronic components or glass droplets, for example on the casing clips for titanium pacemaker casings. Another example is in the membrane of pressure sensors.
We mostly weld in stainless steel, titanium, low alloy steel, carbon steel etc. Almost all materials that can be welded using conventional methods can also be laser welded.
Since a laser can weld very quickly, it's a popular method. Laser welding is in high demand in car manufacturing and in other mass production industries that constantly strive to shorten delivery times.
Engraving
In industry, there is often a need to engrave or tag a product, or to make it traceable. We can do this using Nd:YAG lasers and CO2 lasers.
Examples of different types of engraving include logos, dates, patterns, alphanumeric characters, designations, bar codes or serial numbers. Laser engraving is a quick process and we can also engrave non-flat, spherical, surfaces. No chemicals are needed.
Fast, flexible and lasting
The marking happens at high speed and with high precision. It is a non-contact method and gives a permanent result. It's particularly suitable for products that are impact or shock-sensitive. It's also a very flexible method in terms of the font, text size and shape of the pattern.
You can laser engrave almost all materials, for example, anodized aluminium, stainless steel, carbon steel, titanium, tungsten, paper and many different kinds of plastics.
Drilling
Another major application for lasers is in drilling. Lasers mean that we can drill holes that are only about ten microns in diameter.
Usually holes are between 0.02 and 0.2 mm however.
Drilling happens largely in the same way as cutting, and we can work with the same materials as with laser cutting (read more under cutting). Holes with smaller diameters are created by "drilling" with one or several laser pulses on the same or almost the same point.
We can create holes that have a wider entrance hole than exit hole and holes with very oblique angles. We can also drill tiny holes in dense patterns using a very high speed. This method is used in thin foil filters.
Surface structuring
We use lasers to transform the surface and the surface characteristics of a product.
To obtain the exact characteristics needed, we control the production process using a scanning electronic microscope, i.e. SEM analysis.
Product examples: Dental products, seals.
