Innovative Engineering Solutions for Your Project

Provision of Engineering Services for Design and Development

ABOUT US

We are an international outsourced engineering bureau offering professional engineering services.


Our activities include:


Design and engineering of instruments, technological devices and equipment, test benches, and new consumer products — from concept to production preparation.


Development of design documentation, calculations, creation of 3D models and drawings, without subsequent manufacturing.

ENGINEERING SOLUTIONS

  • Equipment & Instrument Design

    Custom equipment design and engineering — from concept to production readiness.


    We take your idea and turn it into a product ready for manufacturing. From concept and component selection to a complete set of documentation for production handover.


    We take on the development of custom assemblies, tooling, and test benches — from technical specifications to drawings for your production facility.


    Experienced in precision mechanics, optics, and vacuum technology — we understand the specifics of your requirements.

  • 3D CAD Modeling

    Development of 3D models and technical drawings for production.


    3D modeling of complex assemblies and enclosures. We turn sketches and ideas into accurate 3D models, ready for prototyping or manufacturing.


    We create 3D models using industry-standard design software:

    • SolidWorks
    • Autodesk Inventor
    • AutoCAD

    Available formats: SLDPRT, SLDASM, IPT, IAM, STEP, IGES, and others.

  • Design Documentation

    Creation of a complete set of design documentation for new products.


    Design documentation is what turns a great idea or 3D model into a real product — one that can be manufactured, certified, and brought to market.


    We provide a full service — from initial sketches to complete drawing packages compliant with DIN, ISO, or ESKD standards.


    Our clients receive not just documentation, but the confidence that their product can be manufactured without errors, scaled to series production, and certified without delays.

  • Tooling & Fixture Design

    Design and development of:

    • Manufacturing tooling and fixtures (jigs, molds, patterns)
    • Test benches and rigs for product validation
    • Welded structures and fabrications for industrial applications

    Types of fixtures we design:

    • Machine fixtures (vises, chucks, drilling jigs)
    • Assembly and welding fixtures (tilting tables, positioners, assembly jigs)
    • Inspection tooling (gauges, templates, inspection benches)
    • Test benches (mechanical, pneumatic, vacuum)

    Drive types:

    • Mechanical (screw, eccentric)
    • Pneumatic
    • Hydraulic
    • Electro-mechanical

    Experienced with various materials including steel, aluminum, plastics, and vacuum-compatible materials.

  • Innovative Product Development

    Development of new consumer products, including:

    • Medical devices
    • Electronic devices
    • Opto-mechanical instruments
    • Measuring instruments

    We turn your scientific idea or concept into a functional engineered product. We take on the development of complex assemblies or new product lines on a turnkey basis.


    Full confidentiality guaranteed. We offer unconventional engineering solutions built on experience in optics, vacuum technology, and precision mechanics.


    We guide you from laboratory prototype to engineering sample, ensuring reliability and performance in real-world conditions.


    We combine mechanics, optics, and electronics into a single integrated device.

  • Precision Mechanics & Engineering Analysis

    We design systems that move with high precision and reliability.


    Motion systems:

    • Linear motion (ball screws, rack and pinion, linear motors, sliding and rolling guides)
    • Rotary devices (rotary tables, circular interpolators, positioning stages)
    • Kinematic mechanisms (linkage mechanisms, cam mechanisms)
    • Drives and transmissions (servo drives, stepper motors, gearboxes — planetary, harmonic drive, couplings)

    Engineering analysis:

    • Kinematic analysis (trajectories, velocities, accelerations)
    • Dynamic analysis (loads, moments of inertia)
    • Structural analysis for stiffness and fatigue
    • Positioning accuracy calculations (backlash, elastic deformation)
    • Motor and gearbox sizing (torque, inertia, thermal performance)

WHO WE SERVE

Manufacturing Companies 

(Metalworking, Instrumentation, Mechanical Engineering, Vacuum Technology)


We design equipment that solves your production challenges.

We take on the development of custom assemblies, tooling, and test benches — from technical specifications to drawings for your production facility.

We prepare your idea for series production. We create a complete set of drawings and specifications that any manufacturer in Europe or Asia can use to produce your product.

We relieve your in-house engineers by taking on routine design work or reverse engineering, and creating 3D models from your sketches for CNC machining.

Startups & Product Developers 

(Hardware, MedTech, DeepTech)

You have a brilliant idea but lack the engineering team and experience to turn it into a functional product ready for series production.

You have an idea or a sketch on paper, but no budget or time to hire an in-house engineer.

We bring your invention to life and ensure reliability and performance in real-world conditions.

We take you from concept and component selection to a complete set of documentation ready for manufacturing.

Flexible, fast, and comprehensive turnkey project management.

R&D Centers & Laboratories 

(Optics, Microelectronics, Biotechnology)

When launching a new product, a complete design documentation package is required for production. It's unprofitable to divert your own resources to this.

We implement complex scientific and technical problems in metal. We have experience in precision mechanics, optics, and vacuum technology, and understand the specific requirements.

We handle all the paperwork involved in the development process. We strictly adhere to standards (ISO, Unified System for Design Documentation), ensuring confidentiality and accuracy. You receive a ready-to-implement package.

We undertake the development of a complex component or a new product line on a turnkey basis. We ensure complete confidentiality and offer innovative engineering solutions.

Welded Structure Manufacturers

Welded structures of any complexity — chambers, frames, racks, supports, and more.

Load calculations.

Structures in steel and aluminum.

How We Work

  1. Inquiry — Client submits a request.
  2. Analysis — We ask clarifying questions and provide extended portfolio information relevant to your request.
  3. Proposal — We prepare an initial commercial proposal.
  4. Discussion — We discuss project details — technical, financial, and organizational.
  5. Agreement — We define the scope of work, contract, and acceptance terms.
  6. Execution — Work is carried out according to the agreed scope and contract.
  7. Review — We provide interim results and discuss design concepts throughout the process.
  8. Delivery — Client accepts the completed work.

We understand that every project is unique.

We are ready to adapt our approaches, methodologies, and workflows to meet your specific tasks and deadlines.

Clear planning, transparent reporting, and open communication at every stage of collaboration.
