In 1905, Friedrich Heitz resigned from his employment relationship with Carl Benz and founded the craftsmen's firm Friedrich Heitz Modellbau in a suburb of Mannheim. In the following years, HEITZ established himself as a model builder and independently produced foundry facilities as a contract partner and supplier for his previous employer.
Already in the 1920s, after the first world war, the company had 25 employees.
In 1943 the company shifted almost entirely to Grünstadt after three bombs of the Mannheimer plant and changed into E. A. Heitz oHG. Named after the operating son of the founding father Ernst Albert.
By the end of World War II, HEITZ began to focus on its core business of mold making and supplied foundries all over the world with castings, molds and other equipment.
With the introduction of expandable polystyrene (EPS) by BASF Ludwigshafen at the beginning of the 1950s, the operating environment gradually changed to machines, molds and accessories for EPS and EPP processing. During this time, HEITZ was a pioneer in EPS development.
In 1957 HEITZ built the world's first fully automatic molding machine for EPS processing for a British customer. HEITZ, for example, has gradually developed into a plant and machine manufacturer for plastics processing, with the mold construction, which has existed since 1905, still an important part of the business.
In the course of the further development of the automatic molding machines, since the 1970s, machines for casting resin have also been produced, which are mainly used for the production of medium and high voltage insulators.
To this day, HEITZ is constantly pushing ahead. Over the years, the company has developed a special name as a problem solver. Many of the special machines are developed in close cooperation with our customers in order to meet your high requirements.
In addition, HEITZ has expanded the product range with the planning and implementation of turnkey plants. HEITZ is setting up its individually planned, turnkey production facility worldwide.
