Our company history

1970 Foundation of the company by Helmut Diebolder in Osterberg. Range of activity: job order and production of machine controls

1972 Transformation of the company into an electrical installation company with approximately 20 employees.

1975 Helmut Diebolder develops a cable reel as the first manufactured product. The international patented construction enjoy of such a large demand that the old premises for production aren't sufficient any longer. The production and storage space are trebled.

1977 HEDI GmbH was established in October of this year (the name "HEDI" comes from the first letters of the company founder HElmut DIebolder).

1980 A modern industrial company is built at the new commercial area in the neighbouring Babenhausen, after it make no sense to expand the production location in Osterberg.

1985 A new cable reel developed by HEDI receives the test note "good" as only from 16 evaluated products from the donation goods test. The enterprise HEDI employs meanwhile 60 employees. The free manufacturing areas at the location Osterberg are used to establish the new 2nd main pillar, the assembly of cables. There are produced cable harnesses and electrical devices for industrial customers.

1991 A modification and a move of the department assembly of cables to the location Babenhausen is necessary, because the division increased so much. The manufacturing area Osterberg results as manufacturing of small series and custom-made-products as well as for the construction of the manufacturing of new products. 1993 The production program is expanded on plastic socket distributors and industry cable reels. 1994 Robert Diebolder is appointed managing director and at the same time he becomes a shareholder.

1994/95 The company in Babenhausen has to be expanded by another hall for the plastic injection molding, toolmaking and administration departments due to the high demand of the products. The company now has about 80 employees.

1998 Our quality management system rolled out in conformity with ISO 9001 including ISO certificate.

2002 For the production of the new developed cable reels StarLite, Primus and Professional is built a further production hall in Babenhausen. The manufacturing of the new cable reels is made of a highly automated production line. 2003** Further expansion of the manufacturing areas in the division assembly of cables after the redecoration and modification of the older manufacturing halls on the location Babenhausen. The production location in Osterberg is closed. A new product line with various machine lamps is introduced to the market and sets new standards in the price-performance ratio.

2006 The company founder Helmut Diebolder leaves the management at the turn of the year 2006/2007, although he continues to have a close relationship with the company as a shareholder and advisor. The company is then managed by the sole managing director Robert Diebolder.

2008/2009 Rolling out of the new "e.STATION" and "m.STATION" socket distributor series. The production hall for ready-made cables and certain areas of the warehouse are totally refurbished.


Entry into LED technology. The first machine lamp "LED PRO!" with the corresponding cooling technology for high-performance LED´s were developed and introduced to the market.

2012 / 2013

Encouraged by the outstanding success of our LED pro! machine light, we are devoting even more attention to LED technology and are developing our LED Cube as our next lighting product. This sets new standards in the field of work lamps. Even during the market launch phase, the product is further optimised and development on the product is continued.


Our own combined heat and power plant with natural gas technology goes into operation. We generate our own electricity according to demand and use the heat generated in our buildings.

2013 / 2014

Demolition of the old office building from the year 1980. The result is a new, modern and larger administration building so that enough space for the next growth and restructuring steps is available. Some pictures of the demolition and new building can be found "here":https://www.hedi.de/unternehmen/geschichte/neubau-verwaltungsgebaeude-2013-2014.html

July 2016

The founder Helmut Diebolder dies at the age of 74 years. Until recently, he had been involved in the company and contributed his ideas.


HEDI develops an absolute new product - two products in one: HEDI distribution station LED.STATION HEDI, with its lighting distribution stations, is establishing a completely new product category on the market. The development team succeeded in perfectly integrating the light module into the housing design of the two product lines LED e.STATION and m.STATION. HEDI thus creates real all-round talents that compete on the construction site, in the trades and in industry.

2017 / 2018

Introduction of our new machine and workbench luminaire LED ZOOM. For the first time a lamp was developed with magnification function. Two integrated lenses: Ø 90mm: gain 1.75x (= 3 dioptres) Ø 20mm: amplification 3-fold (= 8 diopters) This marked another path in the lighting sector.


The new all-plastic cable drum from HEDI was already presented at the International Hardware Fair in Cologne and at Light & Building in Frankfurt. Already the 7th generation could be presented here. HEDI Generation 7

Already during the development some adjustments and improvements were made. The new cable drum is designed to meet the current (and future) safety standards and requirements of our customers and users to a large extent. For the production of the all-plastic cable drum, investments were made in further machines and another production line was set up within the Babenhausen site.

In the first step, this cable drum will be available as an AC version. Later, more variants will follow.


The company in Babenhausen has to be expanded by another hall.
