Individual laser engraving and laser marking of different materials

As an experienced manufacturer and service provider, we offer you high-quality solutions for individual laser marking. With our extensive laser engraving contract manufacturing services, you benefit from the highest precision with outstanding quality.

The advantages of laser engraving


Modern laser technology enables precise and detailed marking on a wide range of materials such as wood, leather, paper, cardboard, metal and much more. With our state-of-the-art CO² laser technology, we can even cut desired contours such as seals, precision-fit covers and any other geometries from various materials. We place great emphasis on quality and accuracy in every marking.


Whether you need promotional items, gifts or products with custom branding, laser engraving offers a versatile solution. You can have logos, lettering, images or custom designs engraved in a variety of sizes and styles. Every business is unique, so we offer custom laser engraving solutions to meet your unique needs and bring your vision to life.


Laser engravings are extremely durable and abrasion resistant. They provide long-lasting lettering or embellishment that can withstand even the most demanding requirements. This makes them ideal for products that are used often or in tougher conditions.

Laser engraving applications

Marking using laser technology has numerous applications in various industries. Here are some examples:

Industrial Marking:

Laser engraving is ideal for industrial marking, such as engraving nameplates, metal plates, and stainless steel signs. With precision laser engraving, you can create permanent markings that meet the demanding requirements of industry.

Quality Marking and Traceability:

Laser marking allows you to provide high-quality products with precise and permanent markings. In this way, you signal quality and professionalism to your customers.
Engraving with a laser can also be used for product traceability. This makes it possible, for example, to apply unique codes or serial numbers to trace the origin and thus the provenance of your products.

Promotional items and gifts:

Personalized promotional items and gifts are an effective way to strengthen customer relationships and showcase your brand. With laser engraving, you can add your logo or custom messages to products such as lighters, glasses, wooden products, power banks, water bottles, USB sticks and more.

Design and decoration:

Laser engraving also allows for creative design and decoration options. You can decorate wood, slate, metal and other materials with artistic engravings to create unique and appealing designs for your business or customers.

Laser welding at zwerenz industries

Laser welding is a modern and precise process used in various industries. A focused laser beam is used to join workpieces together, creating a permanent weld. It is also used to process or repair production molds for injection molding as well as die casting tools by repair welding, in which broken-out or indented defects are welded on. Due to its high precision and the possibility of welding different materials, laser welding offers many advantages over conventional welding methods. Depending on the specific requirements of your project, we select the appropriate material.

Advantages of laser welding

zwerenz industries is a leading company in Europe providing high quality laser welding solutions for business customers. Our modern machines and qualified specialists enable us to implement almost all customer requirements.


Laser welding enables an extremely precise weld with low heat effects. This ensures high quality and minimal deformation of the workpieces.


Laser welding can be used to process various materials such as aluminum, stainless steel and magnesium. This gives you the flexibility to use very complex geometries in your projects.


Laser welding allows you to join workpieces quickly and efficiently. It reduces welding times and increases the productivity of your manufacturing processes.


Laser welding produces only a small amount of weld spatter and smoke. This ensures clean working conditions and facilitates post-processing of the welded parts.

Areas of application for laser welding

Mold and tool making:

In our in-house mold and tool making shop, we weld using the laser welding process. This minimizes downtime on production equipment and ensures smooth manufacturing.

Contract work:

In addition to our own production, we also offer laser welding as contract work. If you have special welding requirements, we are at your disposal with our expertise.

Key technologies in laser welding

We use various key technologies to ensure high quality laser welding:

CO² laser engraving:

This technology enables laser engraving of workpieces by a laser beam that is amplified with CO2 gas. With this method, we can create high-precision layouts as well as cut contours in materials.

Laser welding:

With YAG lasers, we can mark and engrave almost any metal. This technique is particularly well suited for applications where permanent and precise marking is required.

Ink transfer process:

In this particular marking method, we use materials that change color at the point marked with laser technology. In this way, we create unique visual effects and enable individual design options.

Quality and expertise

At zwerenz industries we are proud to offer you high quality material processing using laser technology. Our company is known for its state-of-the-art and highly diverse machinery, which is operated by experienced and skilled personnel.

To ensure that the welded parts meet the highest standards, we employ various quality assurance measures. During the welding process, we continuously monitor parameters to ensure that welds meet specified requirements.
In this way, we minimize potential defects and ensure high quality.

With our many years of experience and know-how in laser technology, we are able to deliver first-class results. Through efficient processes and careful planning, we ensure that your orders are completed on time and reliably. We work closely with our customers to exceed their expectations.
