Our foundry LIVARNA GORICA, shortly called LIGO Foundry is located very centrally located next to the Italian-Slovenian border north of Trieste, and is for 11 years, a 100% subsidiary of the company ERNST ZÜRN in Munich. The foundry has been greatly modernized in recent years, with new technologies. Our production has been greatly expanded in recent years and new capacities have been created.
Your advantage: You have one contact in Munich (Sales / Technical) and if necessary a security camp here in Germany.

The foundry is mainly specializes in gray iron castings in the range 0.5 - about 24 KG, which are produced on a modern and very fast DISAMATIC line. LIGO has over 60 years experience in the Graugußproduktion for a variety of customers in the automotive, agriculture, hydraulics and pumps industry, engineering, construction, industry, etc.

AGS-additionally provides the possibility of processing castings and machining
and mounting options in their own branch in Germany and takes over the complete acquisition of logistical tasks to delivery.Our logistics network reaches customers throughout Europe to go up to Sweden.

Besides its own Gußherstellung in Slovenia ZÜRN also has a wide network of foundry partners in Eastern Europe and the Far East, which enabled us to you in addition, different materials (eg, aluminum, nodular cast iron, malleable iron, etc.) on a variety of molding equipment cost and from reliable sources produce.

Please find below our company presentation about LIGO and ERNST ZÜRN. More information is also available on our website (which is not quite finished yet, unfortunately).

I would be pleased to receive a request packet on your part for cast iron products (including nodular cast iron) and the consideration in future tenders much so that we can test our ability to compete for your business and the possibilities of cooperation together.

If you should have any questions regarding pre-or ERNST LIGO ZÜRN You can reach me at any time in Munich.

Thank you in advance and a pleasant week.

ZVIREX, Tržič, d.o.o. is a private family-owned company, which was founded in 1991 and based in Zvirče in the municipality of Tržič. In 1998 the company relocated to new commercial premises in the industrial zone at Loka near Tržič, which is today home to the company headquarters.

zwerenz industries characterized by high quality standards that are realized by the coincidence of experience and development.

All parts are manufactured in Germany. Motivated employees and flexibility and allow a high level of customer service a reality. The use of modern communication technology enables our officers a constant flow of information on project and production levels.

Die-cast zinc / zinc die casting
The hot chamber die casting machines, used zinc die casting ensure reliable production with consistently high quality. You can reach clamping forces from 75 kN to 700 KN for castings with a gravity of 0.05 up to 1,000 g. As a standard alloy we process ZL0410, also called ZnAl4Cu1 or Zamak5. We can, however, other Zinkdruckgußlegierungen such as ZL0400 ZL0430 or are possible.
Thanks to optimized production processes also extremely thin-walled castings with excellent properties can be produced.To realize topics such as material and weight savings for the customer is the in-house mold design available incl. This can already be in the ground floor each font, so pass on the railways in the tool so that a fault-free production and an optimal result is achieved.

Plastic injection molding
Plastic parts made on modern machines - this makes it possible to process highly sensitive plastics efficiently.
Our machinery consists of injection molding machines with clamping forces from 25 to 100to. Due to the largely automated production creates the basis for a flexible, cost-effective and environmentally friendly mass production.
Through the in-house mold with design department can already be in the planning and development of the railways invest so that an optimum Ergebis is obtained by an error-free production.
Additional Manufacturing Technologies
• Veredelungs-/Kennzeichnungsverfahren like: pad printing or laser marking
• Installation and commisioning of assemblies
• encapsulation of metal parts with plastics

Materials used:
All common thermoplastics suchExample: ABS, PA, PA6.0, PA6.6, PC, PE, PMMA, POM, PP, PPN, PS, etc.
The materials may be colored by the master batch pigments.

Toolmaking
In the field of tool we offer our customers a comprehensive portfolio of services. We distinguish ourselves above all by our high standard of quality. This is made possible by precision in all operations.
The implementation of individual customer requirements, flexible order handling and a high level of customer service are basic requirements that we can provide.

Laser Technology / Laser inscription
The modern way of laser marking enables the processing of almost all materials.
Many of our machines working in CO ² methods by which incorporate by laser beam headings, or similar motives in the works. With this method it is also possible to cut from materials desired contours.
Another lettering style is achieved with YAG lasers.This technique allows the marking / engraving of almost all types of metal.
The third area is the lettering in the color change process dar. Here materials are used which change by the addition of specific components by marking with laser technology at the appropriate place their color.
In zwerenz industries is in this future-oriented field of work by one of the leading companies in Europe. Conceived at the highest technical level of machines and the technical personnel employed enable the implementat...

Over time, our company has developed from a craft business to a modern industrial company.
Starting with shiny turning and milling tools made from natural diamonds to
to cutting and grinding tools made of polycrystalline diamond (PCD) and cubic boron nitride (CBN).

In order to meet the high demands of industry, our machines and measurement equipment are state of the art
and are subject to continuous development.
