Aluminium parts

Please note that Dejoie will be closed from Friday 29 July to Sunday 28 August 2022.

We will have an office and shop on duty during weeks 31 and 34.

The Dejoie team

To bring you a complete service, we are able to provide you with a complete product integrating elements of your supply.

We can also take care of all the supplies linked to this finished product, whatever their manufacturing process or material (example: mailboxes).

Dejoie provides logistics and storage throughout the product life cycle, from the management and maintenance of your tools to the dedicated packaging of your parts. (Number of parts per box and pallet size) with your referencing.

Thanks to our partners, we will ensure delivery on site, on logistics platforms or directly to your customers or partners.

In order to bring you more services and to provide you a complete service, we are able to take care of :

- Machining of the parts according to the established plans.
- Heat treatment of the parts (T6 tempering) to improve the mechanical characteristics.
- Surface treatment (anodizing, painting...).

We have an in-house semi-automated surface treatment line before painting, in compliance with the ROHS* directive.

Our structure has a solvent-based liquid paint booth with conveyor, different finishes are available :

- Finishing with the tint in direct.
- Primer + tinted finish.
- Primer + tinted finish + protective varnish.
- Other systems on request (filling primer + sanding for high quality finish).

We are able to offer you a powder paint, in subcontracting.

*ROHS is a European directive that provides legal preventive measures to limit the use of certain hazardous substances.

The Dejoie team

For the realization of a series, it is necessary to count 6 to 8 weeks for an order of series part except machining or painting. And 10 to 12 weeks for a serial order of finished parts or sub-assemblies.

1. Assembly / Adjustment of the mould

The manufacturing process begins with the assembly and adjustment of the mold. When the mold is installed, the team can carry out the casting of the parts.

2. Casting of the parts

Dejoie has 5 melting furnaces with capacities ranging from 200 to 500 kg.
We also have 9 hydraulic moulding machines, one of which is a tilting machine, which are used to open/close the mould and eject the cast part.
The casting is done with a ladle by gravity.

3. Deburring of the parts

Once the part is solidified and its feeding system removed, it is deburred by our teams.
The operation is carried out with a backstand, a disc sander, or with manual means (angle sander, belt grinder, etc.)
We are equipped with a tribofinishing machine with ceramic media and a polishing machine with stainless steel balls.
This operation allows; to eliminate the marks of the feeding system and the burrs.

4. Drilling and tapping

On request, we can provide drilling and tapping services on the parts.

5. Packaging

We package your parts according to your needs (number of parts per box, pallet size, pallet height, labelling, etc.) to facilitate reception and storage operations.

The Dejoie team

After having well defined your need, and your specifications. We can submit you a 3D printed plastic model.

If you want a functional prototype of the aluminum part, we can realize from a 3D printed sand mold, a simulation of the part. This will allow us to evaluate the "resistance" of the part.

The material of the mold is adapted to the life of the mold (steel or cast iron).

After joint validation of the part or the whole. We launch the creation of the serial tools, which you will own.

Upon receipt of the mold, some initial samples are made, allowing the drafting of the manufacturing range. These samples are used to test and validate the product in its environment and to make modifications, if necessary.

The Dejoie team

You have a project, a part, an assembly to be realized in foundry and/or in sheet metal work.

- We can help you define your needs and design your product
- We produce aluminum castings: prototype and/or series.
- From 50 grams to 15 kg in foundry or sheet metal work.
- Machined or assembled, with heat treatment and/or surface treatment (painting).
- Small and medium series: from 100 to 30 000 parts per year.

To meet your needs, our teams will accompany you throughout your project with the help of its know-how, complete production equipment, and a set of partners.

The production of a part can be divided into 6 steps.

At first, you can send us your project by email to our business manager: julien.guillaume@dejoie.com and on our address contact@dejoie.com.

To be the most efficient in the analysis of your request, please provide the following information to define your need :

- Technical definition of the product (The mass of the part, material, a plan identifying the different machining operations.).
- Use/functionality of the product (The technical and environmental constraints).
- Aspect of the product (integration in an assembly, desired finish).
- Annual volume and/or rate of production envisaged.

The definition (plan) of the product can be treated :

- From the existing product / assembly : we can propose the realization of a 3D scan.
- 2D files, paper plan in formats (PDF, DXF, DWG, Native SolidWorks, or other formats).
- 3D files in formats (STEP, Parasolid, Native SolidWorks, IGES, or other formats).

During product development we are able to study a new design, check the mechanical stresses of the product, and perform numerical simulations of the foundry filling, thus reducing development time.

L’aluminium est un matériau totalement recyclable ;
100% de l'aluminium trié est recyclé. En recyclant l'aluminium, on économise des ressources naturelles et 95% de l'énergie nécessaire pour fabriquer l'aluminium en première fusion. il est soumis à une opération de refusion et d'affinage: introduit dans un four, le produit est fondu et dégazé.
L'aluminium peut être réutilisé afin de confectionner de nouveaux produits et de lui donner une seconde vie.

DEJOIE recycle donc l’ensemble des chutes de sciage ou systèmes d’alimentation, en l’intégrant dans la préparation de nos fours, à hauteur de 30 à 50% avec des lingots de 1ère fusion.
Nous envoyons les résidus de meulage ou copeaux, en recyclage en filières agréées qui les traiteront et affineront pour donner de nouveaux lingots.
