Dresden - cradle of the camera industryDresden - one of the birth places of the camera industry. PENTACON has a long history, starting in the early 20th century.
The
first time the company did business by the name PENTACON was in 1964
when several companies in the area in and around Dresden were unified.
The name comes from the Pentaprism of modern SLR cameras and the early brand name Contax, which was the predecessor before world war II. After the company merger the state-owned PENTACON became the biggest employer in the region and in 1980 around 9,000 people worked for PENTACON.Part of the Jos. Schneider groupIn 1990, parts of the company trust were sold to the Jos. Schneider group
in Bad Kreuznach and from then on is subsidiary of one of the leading
enterprises in the fields of optics. In 1997, the present PENTACON GmbH
has beend founded and employs ca. 125 people.From the medium to the large scale productionWith
decades of experience in precision engineering and the processing of
metal and plastics, PENTACON continously invests in production
technology. Starting with turret lathes and small size grinding
machines, we step-by-step enhanced our capabilities. New technologies
had been tested and so, change towards a large scale production has been
completed.
Today, PENTACON uses
various Swiss turning machines, chained puncture milling machines for
extruded parts and INDEX machines for large batch optical parts.High quality plastic injection moldingAlso
the plastic injection molding had been an integral part with PENTACON
for several decades. After 1997, we started with standard production on
machines with clam forces of 50-150t but quickly enhanced our
activities in this field. Using the experience in manufacturing
cameras, PENTACON specialised in coating of inserted parts. Optical and
medical plastic products, which require clean room production are part
of our portfolio just like two-shot parts are in large scale batch
production.Camera manufacturing 'Made in Germany'The
camera manufacturing is still part of PENTACON. Here, we have
specialised in developing and manufacturing system solutions for
industrial partners and concentrate on digital scan cameras with high
resolutions.
Also the developing of
industrial image processing systems offered new possibilities to
monitor the own production as well as external production to secure
high quality requirements and downsize costs. Today we are a respeced
partner for the inspection of synchronizing rings, the inspection of
surfaces for scratches, blowholes and fissures as well as the
inspection of boreholes and threads.DAkks accredited measuring and calibration laboratoryTo
support the quality control, PENTACON installed an own measuring
laboratory. By the end of the 1990s, we applied for an accreditation at
the German Accreditation Body for gauge blocks. Since then we are
undergoing annual revisions for the accreditation and earn the required
certificates. We continously enhance our service portfolio and also
counsel external partners as a measurands calibrator.
