TARAMM manufactures titanium precision cast parts meeting following criteria :

Size and Weight

  • The castings must be accommodated in an annulus defined by two cylinders of 60 and 650mm diameters and 450mm in height.
  • Minimum part thickness : from 0.5 mm to 1.5 mm depending on the magnitude of the area.
  • Part weight must not exceed 7 kilograms (15,4 pounds).
Mechanical properties

The ultimate strength of cast titanium alloys is very high. It is equal to the cast steel alloys ultimate strength, but the titanium density is only 4.5 as compared 7.8 for steel alloys.

A heat resistance up to 400°C/500°C and an exceptional corrosion resistance and their bio compatibility (no rejection by human body) justifies the use of cast titanium alloys in many fields.

Shapes

There is practically no limitation concerning the complexity of shapes that can be obtained. However TARAMM company will propose, when necessary, shape modifications in order to make the manufacturing easier or to reduce the cost.

Machined castings

Thanks to a subcontractor network (machining subcontractors approved by TARAMM), we are able to supply machined castings (with bearing fittings if required) ready for fitting on aircraft or engine.

.Product advantages
There are many advantages in using titanium investment castings :

Economical : Melting bars or sheets remnants with traceability and a cost six times lower than the virginal metal ingot.

The investment casting process enables shapes which are very close to the final shape. Machining is restricted to contact or functional areas for which very tight tolerances are required.

Waste of material resulting from machining parts is consequently significantly reduced.

The investment casting process enables to obtain very complex shapes at a low price in comparison with other shaping processes such as : machining from a massive block, machining from a forged part, assembly by welding, etc...

This is even truer for titanium which is an expensive metal and difficult to machine.
Technical : Possibility of obtaining castings with very thin walls due to the " superheating " of the melted metal.

Possibility of increasing parts rigidity while reducing their weight providing that the design of the casting is optimized for investment casting process. TARAMM is helping its customers to optimize their design.

Elaboration of any kind of alloy
Quality : No pollution of the liquid metal by the crucible. The metal is in " semi levitation " and has a very small contact area with the crucible.

The liquid metal resulting from electromagnetic induction stirring is perfectly homogeneous.

No Alpha case (metal superficial pollution by the ceramic mold) due to the pouring into a cold mold allowing a quick solidification.

Optimal conditions to obtain above advantages :

The earliest TARAMM can be involved in a project, the highest will be technical and financial gains for a customer.

TARAMM will be happy to help you on the design of your castings in order to optimize quality, mechanical performances, cost and delivery times of your parts.

 
.Taramm's flexibility
TARAMM's structure enables quick adaptation to various working methods of our customers.

Examples :

  • TARAMM is working with computerized data file exchange and with Suplly Chain Management tools.
  • TARAMM is supplying certificates of conformity and delivery notes with bar codes to several customers who asked for this possibility.
  • Standard manufacturing cycles being 3 months, TARAMM got organized to ship parts within 10 days from orders releases related to AIRBUS contracts.

 
.Customer support
TARAMM can provide expert consultation on the design of your cast parts :

We collaborates frequently with our customers on the design of their precision titanium castings.

For example, we will be able to increase your parts rigidity while reducing their weight (Investment casting process enables ribs and hollowing out, that are difficult or impossible to obtain by other shaping processes).

In addition to technical gains, you will also be happy to get cost reductions thanks to TARAMM's design advises.

by TARAMM with CAD tools

Most important gains are obtained by involving TARAMM in your project at the beginning of your cast parts design. However, TARAMM has already got successful results in projects which were in an advanced stage .

TARAMM is using Vellum Solids CAD software that can import the following formats :

- IGES
- STEP
- ACIS SAT
- DXF
- DWG
- ProE
Technical trainings organized by TARAMM :

Investment casting process advantages are not yet very well known by design offices. TARAMM is ready to perform conferences with slides or video projection in order to show and demonstrate the possibilities of this process and to prepare design engineers to use successfully this technology.

We invite design office managers, buyers, quality assurance managers, laboratory managers, production managers, etc... to attend our conferences.
