Auszug aus der Geschichte
Wilhelm Hossinger and his three brothers founded the company Rahmenerzeugung Hossinger in Wassersuppen (now CZ).
The company was first established in Roding.
To be able to manufacture purchased parts in-house in the future, the company purchased its first injection molding machine.
The company moved into its current location on Robert-Bosch-Straße.
Erhard Hossinger became the second-generation head of the family-run company.
New production facility for expanded injection molding and plastic window manufacturing.
Just 20 years later, the building was expanded and the new spray painting facility was inaugurated. In the years that followed, the technologies were also continuously refined.
Armin Hossinger, the current managing director and owner, joined the family business and used his expertise to support operations in many areas.
The monosandwich technique was introduced.
One year later, internal gas pressure technology was used for the first time.
This was followed by multicomponent technology
Shortly before the turn of the millennium, the company ventured into a new industry and began cleanroom manufacturing.
To stay on the cutting edge, the company acquired seven fully electric injection molding machines. At the same time, a joint venture was established with Wise-Optotech Limited. The joint venture partner is headquartered in China.
As a full-service partner, the company is highly regarded in the industry, which is why the assembly area was redesigned and expanded to include an ESD zone.
Armin Hossinger, a third-generation member of the family, succeeded his father Erhard as sole managing director and owner.
The acquisition of a second mobile cleanroom made it possible to label and package products.
The first products were registered with the FDA.
A stationary cleanroom was added to the assembly area.
The company responded to its growing business by constructing a new warehouse and logistics center. This resulted in an eightfold increase in storage capacity.
New projects called for a strategic expansion, which tripled the production area for injection molding.
100 years after its founding, whr Hossinger is a specialist in plastic injection molding with 72 employees. The family-owned business sees itself as a full-service provider and offers everything from production to assembly and in-house toolmaking.
