Material Expertise

Georg Jordan uses different manufacturing techniques – vacuum casting [VG] and automatic pressure gelation [APG] – as well as cast resins regarding types of insulators and applications – indoor and outdoor use. All material variants meet the required different property profiles to the area of application.

In line with these requirements, epoxy cast resin materials were developed as aromatic and cycloaliphatic formulations for the production of insulating parts (DIN 16946).

The specified values were determined on standard rods as a means to compare different materials under the same test conditions. The various production techniques (vacuum casting, automatic pressure gelation APG, etc.) and the wide range of applications for insulators (indoor and outdoor) also give rise to differing property profiles that the affected material must exhibit.

In line with these requirements, epoxy cast resin materials were developed as aromatic and cycloaliphatic formulations for the production of insulating parts (DIN 16946). All formulations used are suitable for tropical environments and termite proof.

The plastic materials we use undergo continuous internal and external monitoring. The used material is also UL listed: QMFZ2.E303635.


Standard material formulations:

  • Indoor use – aromatic base (61.A/M, 62.A)
  • High temperature use – aromatic base (65.A)
  • Outdoor use – cycloaliphatic base (CEP) (64.A)
  • Outdoor use – hydrophobic; cycloaliphatic base (HCEP)
  • Outdoor use – semi-flexible; hydrophobic; cycloaliphatic base (S-HCEP)

The random we do not leave anything. Who like us, want to provide the best quality must master in particular the complexity of the production. Therefore, our machine park is on the cutting edge of technology, the degree of automation is very high and our employees are highly trained. Certified raw materials and an absolutely constant quality are the basis of our reliability. Our customers appreciate that.


Production process

Georg Jordan uses regarding different manufacturing techniques two proven casting procedures:


  1. Vacuum casting[VG]; casting under vacuum
  2. Automatic pressure gelation[APG]; casting with overpressure


With these two methods a large flexibility exists in order to react quickly to customer requests. The quality of the products or of both processes convince all at once.

The raw material processing is carried out with fully automatic computerized process engineering. The casting resin is passed through pipelines directly to the casting chambers. A continuous supply and secure quality is so guaranteed.

In the production process of GEORG JORDAN more modern technologies are used:

  • Mixing and metering components
  • Degassing equipment
  • Casting chambers
  • Forms
  • Dryers respectively ovens


All “out of one cast” – according to your requirements and your needs.

The project management GEORG JORDAN has a central task to fulfill our customers’ expectations on the project.

The systematic and methodical application of processes and procedures is thereby controlled and monitored centrally. The professional approach makes the development of products that better plannable and verifiable. Effectiveness and efficiency characterize the process and the actual end product.


GEORG JORDAN holds within the meaning of project success always the critical success factors in mind.

  • Time: duration and dates
  • Budget and costs
  • Content, scope and quality of project results


Quality Assurance

Procedures and products are continuously tested both internal and external at Georg Jordan and are multiple certified.

Our goal is it to provide our customers safe, environmentally and their expectations corresponding goods and services.

Temperature range

In compliance with VDE 0441 Part 3 and IEC 60660 respectively, the mechanical and electrical properties of all insulators are suitable for a minimum temperature range of -20 to +75 °C. Insulators may be produced on request for other temperature ranges as well.


Tolerance data

With respect to the dimensions, please consider the tolerances according to the standard DIN ISO 2768g.


Tool Making

Here takes your idea a shape.

The tool respectively the tool manufacturing is the crucial final step between innovative development and economic production.

Georg Jordan sets also here from the outset on performance and quality: We develop based on our decades of experience modern tool concepts. Modern CAD systems, CNC machines and closely cooperating partners guarantee professional product solutions.
