In the packaging industry, a high-performance machine is far more than a sequence of automated operations. It must meet a specific need, integrate seamlessly into a production environment, comply with sometimes complex product requirements, and support a company’s growth. Behind every transformation of a customer’s requirements into an industrial solution is a dedicated team: the Engineering Department.
As a French manufacturer of packaging solutions since 1991, CDA places its Engineering Department at the heart of every project. Whether developing a filling machine, capping machine, labelling machine, monobloc system or a complete packaging line combining several functions, the objective remains the same: to transform a real production requirement into a reliable mechanical solution perfectly suited to the product.
But how does this transformation actually take place? What are the different stages involved in turning a customer’s request into a machine? And how does the Engineering Department help secure the success of a packaging project? Here is a step-by-step overview of how CDA’s Engineering Department turns a customer requirement into a mechanical solution.
Understanding the Real Requirement: The Engineering Department’s First Mission
Before discussing mechanics, conveyors, production speeds or automation, the first priority is understanding how the machine will actually be used. The starting point of any packaging project is not the machine itself, but the customer’s requirement.
That requirement may take many different forms:
- Automating a previously manual production process;
- Increasing production output that has become insufficient;
- Improving filling accuracy;
- Ensuring more consistent cap tightening;
- Achieving precise label application;
- Combining several operations within a compact monobloc machine;
- Integrating new equipment into an existing production line;
- Anticipating future format changes or increased production volumes.
The Engineering Department’s role goes far beyond the customer’s initial request. A customer may simply say, “I need a filling machine.” In reality, the questions to answer are much broader:
- What product needs to be packaged?
- What is its viscosity?
- Should the filling process be volumetric, gravimetric, gravity-fed or peristaltic?
- What type of container is used: bottle, vial, jar or jerrycan?
- What are its dimensions, material and shape?
- Does the container need to be screw-capped, capped, crimped or simply closed?
- Will labels be applied to one side or several?
- What production rate is required today… and in the future?
- Does the customer need a standalone machine or a complete packaging line?
This analysis phase prevents one of the most common mistakes: selecting a standard catalogue machine when the actual requirement calls for a tailored solution. The Engineering Department therefore acts as a translator between the customer’s industrial reality and the future mechanical design.
Analysing the Product, the Container and the Packaging Process
An efficient packaging solution is designed around three essential pillars:
- the product to be packaged;
- the container and its closure system;
- the customer’s production process.
The Product: The Starting Point of Every Design
In any filling project, the characteristics of the product directly influence the technology selected. A free-flowing liquid, syrup, oil, cream, gel, foaming product or sensitive formulation all require different filling approaches.
The Engineering Department therefore evaluates several key parameters:
- viscosity;
- density;
- filling temperature;
- the possible presence of particles;
- sensitivity to air or foam;
- hygiene and cleanability requirements;
- compatibility between the product and the filling components.
This assessment determines the design of the most suitable filling machine: the number of filling nozzles, pump technology, required accuracy, production speed, ease of recipe changeover, cleaning procedures and many other technical aspects.
The Container: A Key Element for Filling, Capping and Labelling
The same product may be packaged in 10 ml vials, 250 ml bottles, 5-litre jerrycans or uniquely shaped jars.
The container itself directly influences:
- the conveying system;
- guide rails;
- holding tooling;
- centring devices;
- positioning beneath the filling heads;
- the label application method.
For this reason, the Engineering Department never focuses solely on the machine itself. Instead, it considers the complete combination of product, container, closure, label and production speed to deliver a fully coherent solution.
The Overall Process: A Machine Must Fit the Reality of the Production Facility
Designing a packaging machine is not simply about making an isolated station perform efficiently. It also requires understanding:
- the layout of the production facility;
- the available floor space;
- product flow direction;
- interfaces with existing equipment;
- operator constraints;
- feeding, discharge, inspection and marking requirements;
- medium-term production development objectives.
This is where the Engineering Department provides exceptional added value. Rather than designing an ideal machine in theory, it develops a solution that integrates seamlessly into an existing production environment.
From this point onwards, the project becomes much more tangible. It evolves into a clearly defined set of technical functions to fulfil.
Choosing the Right Solution: Standalone Machine, Monobloc or Complete Packaging Line
At this stage, the Engineering Department works closely with the Sales Department. Together, they answer a key question: which packaging solution best meets the customer’s requirements? Depending on the project, several approaches may be considered.
A Standalone Machine: Meeting a Specific Requirement
In some projects, the customer’s needs focus on a single operation:
- A filling machine to improve dosing accuracy:
- Semi-automatic models such as the K-Net, K-Dy, K-Dense or the Piston Trolley;
- Automatic models such as the K-Net Auto and K-Line S.
- A capping machine to automate the closure process:
- A labelling machine to improve application quality and production speed:
- Semi-automatic models such as the Ninette 2 and Ninette Flat;
- Automatic models such as the Viti, Solo and Ninon ranges.
This approach is particularly suitable for manufacturers wishing to automate their production line gradually or those who already have part of the necessary equipment in place.
The Monobloc: Combining Several Functions Within a Compact Machine
When several successive operations are required, for example filling, capping and labelling, the Engineering Department may recommend a monobloc.
At CDA, monobloc systems combine the main packaging operations within a single machine, offering a compact footprint, smooth product flow and valuable space savings.
This solution is particularly well suited when:
- available floor space is limited;
- production flow needs to be simplified;
- several operations must be synchronised;
- increased productivity is a key objective.
The Complete Packaging Line: Designing a Fully Integrated Process
For more advanced projects, the Engineering Department can go beyond a single machine and design a complete packaging line.
Rather than simply automating one stage of production, the objective is to organise the entire packaging process, including:
- container feeding;
- filling;
- capping or screw-capping;
- labelling;
- conveying;
- and, where required, inspection, marking or product accumulation.
This approach is especially relevant for manufacturers seeking to standardise their production, significantly increase output or improve the repeatability and reliability of the entire packaging process.
Designing the Solution: When an Idea Becomes a Machine
This is where the Engineering Department fully enters its core area of expertise: transforming a functional requirement into a practical mechanical solution.
To achieve this, engineers must solve a wide range of technical challenges, including:
- ensuring containers move steadily throughout the machine;
- positioning each container accurately at every station;
- maintaining reliable filling accuracy despite product variations;
- applying a consistent tightening torque during capping;
- positioning one or more labels precisely at the required speed;
- enabling quick and simple format changeovers;
- ensuring the machine is accessible, easy to adjust and straightforward to maintain.
Adapting the Technology to the Application
The Engineering Department does not simply apply the same standard technology to every project. Instead, each solution is selected according to the customer’s actual production requirements.
This includes choosing:
- the filling technology according to product viscosity and the required level of accuracy;
- the capping head according to the type of closure;
- the labelling configuration according to the container format and the number of labels to be applied;
- the conveyor architecture according to product stability;
- the tooling according to the expected format changes.
Every technical choice is therefore driven by practical application rather than by standardisation.
Testing and Fine-Tuning: Improving the Solution Before Production
For every packaging project, the Engineering Department incorporates a comprehensive validation and optimisation phase before the machine enters production.
At CDA, this involves:
- product and container trials;
- validation of guide systems;
- adjustment of tooling;
- optimisation of format changeovers;
- integrating feedback from real production environments.
This stage is essential for ensuring the reliability of the final solution. The closer the collaboration between the Engineering Department and the technical, sales, assembly, automation and after-sales teams, the better the machine will match the customer’s operational requirements.
Turning Customer Requirements into a Packaging Solution
Transforming a customer’s requirements into a packaging solution is not simply a matter of selecting a machine from a catalogue. It is a process of analysis, interpretation, engineering and continuous optimisation.
In the packaging industry, that solution may take the form of a filling machine, a capping machine, a labelling machine, a monobloc system or a complete packaging line. Whatever the configuration, the guiding principle remains the same: understand before designing, adapt before standardising, and engineer for long-term performance.
