3defacto’s mechanical engineering develops efficient, high-end, top-quality special-purpose machines: the long standing experience and specialisation in one-stop engineering services allows machine construction “made in Germany” where individual wishes and requirements are optimally implemented. This is already reflected in planning, the selection of individual hardware components, the project-based production engineering, the adjusted control engineering, and ultimately the energy-efficient turn-key machine. This enabled 3defacto to hand over to many satisfied customers optimised,
customised machines which impress with their economic efficiency, dependability and high security standards even after years. In order to lastingly keep up the own demands on the qualitative competence and state-of-the-art know-how, 3defacto intentionally nurtures the experience and knowledge exchange among the engineers from construction and mechanical engineering. This method results in many successful engineering projects and innovative constructions in special-purpose machine building, e.g. the big-bag emptying station BBU 2000 filed for patent application.



3defacto offers professionally and individually optimised mechanical engineering from one source and supports his customers from the idea to the start-up. Our services for the Mechanical Engineering business unit include:

  • Component optimisation for individual solutions
  • Process engineering design
  • Calculation of project costs and effort

Construction and machine building

  • Construction of components, special-purpose machines (made in Germany)
  • Implementation of already existing customer constructions
  • Space-saving designs
  • Implementation of customer-specific designs concerning paints and materials
  • Project-related production engineering according to state-of-the-art standards
  • Optimised and timely construction of products

Delivery and start-up

  • Handover of ready-to-use machines, i.e. completely assembled prototypes and small series
  • Timely delivery of hardware
  • Including control and automation technology

After-sales service

  • Development of documentations
  • Support in technical and functional questions
  • creation of project-specific FMEAs according to customer standards

Delivery programme

3defacto looks back on 15 years of experience in mechanical engineering: our products are “made in Germany” and of highest quality. We deliver energy-saving and efficient special-purpose machines
across the globe and in accordance with high security standards. The following machines are manufactured in our Darmstadt production site and handed over as turnkey projects:

The big-bag emptying station BBU 2000

This automatic emptying station has been developed by our specialists for bulk materials and registered for patent approval. The BBU 2000 is energy-saving and reliable, and stands out for its short handling time. It is an optimised plant with maximum customer benefit. Its use yields substantial savings in production, dependability, and user safety. The big-bag emptying station convinced our customers thanks to its pivoting frame, the defined loading and unloading, integrated weighing system, automatic operation, and compact design. Further information about the BBU 2000 can be found here.


The container unloading stations

Whether for polyol, isocyanate, resins, waxes, or paints: our container unloading stations are optimised for the relevant product and ready to use. The versions are adjusted to the general conditions and requirements of our customers: with or without agitator/ stand pillar, with electric pump or compressed air-operated membrane pump, or in a heated version and with 150 litres buffer container in the collection tray, including the embodiment according to ATEX. More information on our unloading stations can be found here. If you have any questions, do not hesitate to contact us.


Non-hydraulic XY adjustment device

This innovative, hydraulic-free XY adjustment unit for automotive is safe, requires little maintenance, and is highly efficient. The electro-mechanical version involves little maintenance effort and low operation costs. The adjustment device allows flexible positioning of the vehicle, as all four modules can be set in a biaxial fashion, and a quick and accurate adjustment to the vehicle size by means of a rack and pinion system with servo drive. The machine features a compact construction, simple assembly, and highest level of safety: the self-locking construction of the clamping device guarantees maximum protection even in case of a power outage. The configurable adapter allows a flexible connection to operating cylinders or actuator. The XY adjustment device can be delivered in manual, motor-driven, and automatic variant and can be used for vehicles of up to a maximum weight of 3,500 kg. For further information, please do not hesitate to contact us.
