Since 2011, we have been dedicated to developing successful projects that blend multidisciplinary know-how with innovative thinking.
Our mission: to design and deliver projects that empower your success.
At DIENG, a winning design is just the beginning.
With expertise spanning mechanical, electrical, materials, and manufacturing engineering, we ensure that every idea evolves seamlessly from concept to reality.
Our engineering expertise is outstanding, but our ideas are what truly set us apart — the added value that drives innovation, product improvement, and higher productivity.
An exclusive Project Manager will be dedicated to your project, following every stage with care and precision — ensuring effective coordination, on-time delivery, cost efficiency, and clear communication
Our structure is designed to ensure top quality and fast project development.
At the core of every successful project lies a highly organized and efficient team.
Concept design represents the beating heart of Dieng’s creative and technical process.
It’s the stage where ideas take shape and become tangible solutions, guided by a combination of strategic vision, engineering expertise, and innovation.
Starting from each client’s specific needs, our team of experts develops tailor-made concepts, translating goals and constraints into functional and sustainable models.
Every detail is carefully analyzed — from ergonomics to design, from technical performance to system integration — ensuring the perfect balance between aesthetics, functionality, and cost.
In the concept design phase of a new machine or product, our engineers combine mechanical, design, and electronic expertise to define the core principles and guidelines that drive each project.
At Dieng, concept generation is a serious matter. We begin by analyzing the challenge to define key operating principles. Working side by side with our clients, our team develops conceptual layouts and models that consider both technical and economic factors, ensuring the most efficient and cost-effective solutions.

We bring our machines and systems to life through advanced electrical engineering and automation expertise.
Our team designs and develops electrical systems, control panels, and PLC software that ensure efficiency, safety, and reliability in every project.
From the definition of control architectures to on-site commissioning, we manage the entire process — integrating hardware, software, and field devices into a cohesive and high-performance system.
Design of electrical diagrams and control systems
PLC and HMI programming
Development of automation architectures and control logic
Integration with mechanical and pneumatic systems
Testing, commissioning, and technical documentation
For many years, we have been supporting our clients with the design and manufacturing of special equipment and custom machinery that assist in production processes and mechanical component testing.
This expertise stems from our extensive experience in the manufacturing sector, allowing us to deliver efficient, practical, and reliable solutions
Engineering and manufacturing of special production equipment
Design and development of custom machinery for specialized processes
Design and manufacturing of testing machines for mechanical components
We assist our clients through technical consulting services aimed at achieving CE certification for products, special equipment, and custom machinery — ensuring compliance, safety, and conformity with European regulations.
Our CE Certification service is closely integrated with our structural analysis expertise, allowing us to produce all the documentation required for the Technical File and the calculation report.
We guide our clients through every phase of the process — from system setup and technical documentation to Notified Body certification and ongoing compliance.
We also provide technical writing and translation services to support full CE conformity.
Each directive defines its own compliance procedures and documentation depth depending on the product’s level of risk and complexity.
Typically, the certification process includes:
Preparation of the Technical File and supporting documentation
Execution of structural analyses and calculation reports
Implementation of a production control system
Notified Body audits, where applicable
We are proud to be a Dassault Systèmes partner for SIMULIA solutions — powerful simulation tools that enhance performance evaluation, reliability, and safety assessments of materials and products well before physical prototyping, accelerating innovation and reducing development time.
