Products and Processes

R&D office to design and industrialize your products :

In order to help you in each step of your parts development, Sival Group owns CAD software such as Top Solid or the Magma flow simulator software.

title

During the early stage of parts design, our engineer can advise you on the best design to match your technical requirements. We will improve as well the quality price ratio from the beginning of the design stage.

Our engineer will build 3D models on your parts, looking to optimize the technical specifications such as mechanical constraints, pressure resistance, visual aspect, deformation… and will help you choosing the best aluminium alloys to increase technical requirements over the EN1706 standard.

We think the parts design integrating our own constraints (foundry and CNC machining) as well as other functions such as surface treatment, painting, …

A few examples of the current used aluminium alloys :

AS7G, AlSi7Mg, EN AC-42000, AC-42100, AC-42200, AU5GT, AlCu4MgTi, AlCu4Ti, AC-21000, AC-21100,2017, 2017A, AU5NKZr, AlCu5NiCoZr,AS13, AlSi13, AS12, AlSi12,AS10G, AlSi10Mg, AG3, AlMg3, AG3T, AlMg3Ti, AZ10S8g, AZ5G, AU4T,….

Process and production flow :

The Sival Group implement the gravity sand casting or gravity resin bonded sand casting for small and medium size parts from a few grams up to 400kg.

We are building internally our sand cores with 4 semi automatic machines, using our core boxes having a capacity from 2,5 to 25 litres

We are using gravity die casting technology for few grams products up to 30kg with half dozen of semi automatic workstations

Your foundry is also offering you the possibility to die cast complex parts integrating sand core or metallic inserts technology into the mould.

For heat treatment, Sival Group is owning 2 furnaces qualified for aircraft industry (class 3- tolerance ±3°C) and 2 tempering furnaces

Our staff is qualified as well to readjust parts after heat treatment, control on 3D machine…

Whenever it’s necessary, grit blasting and sand blasting processes can be implemented internally.

The CNC machines production unit is composed by homogeneous range of Mazak equipment, all equipped by CNC 4 and 5 axis, for parts size up to 800mm3.

Another high speed drilling production unit, with 4 Brother equipment can machine parts up to 800mm3.

Le Pôle Usinage Grande Cadence comporte un parc homogène de machines à commandes numériques MAZAK 4 et 5 axes pour des pièces allant jusqu'à des volumes de 800mm3.

The pool of machines is completed by CNC Mazak turning equipment for parts Ø450mm x 800mm.

This pool of equipment allows us to match expertise, competitiveness, accuracy and big production batches for any kind of raw material.
