Plastic injection

Our core business

Set in the Ardennes, in the heart of a department and a group historically focused on metallurgy,
CEVA has imposed thermoplastics relevant as a real alternative to metallic materials.

The changes in technical regulations, they impose us a daily reappraisal:
– Commitment to environmental certification policy
– Technological watch on the “green” materials, biomaterials …

CEVA Technologies - injection - bi injection - tri injection

Mono-injection 

Plastic injection specialist for 20 years, our knowledge of longer date is the single injection. Our experience over the years has allowed us to develop other technologies such as bi and tri-injection or overmolding.

Our equipment :

Press 100 tons    |    Press 150 tons    |    Press 160 tons    |

Press 200 tons   |    Press 420 tons

Bi-injection 

Injection of two different materials simultaneously or sequentially from one press and a single tool offers the possibility of combining materials with specifications and / or specific aesthetic of the same part.

We offer different technologies for these two types of injection:
– The Rotary mold
– Plateau Rotary press
– The Transfer of parts by robot 2 presses operating in “tandem“

 

Our equipment :

Press 110 Tons turntables at 90 ° |   Press 250 tons

Press 320 Tons rotary base 45 °

Advantages

Economic :
prevent or eliminate post production assembly operations

Aesthetics :
provide special touches or rendered with different colors

Technique :
combine rigid or flexible polymers, possibility of seal

Tri-injection 

We are also specialist in the tri-injection. Three different materials, colors can bring value-added to an unique part.

Our equipment :

Press 200 Tons turntables 90 ° or 45 ° rotatable base

Overmolding

Overmolding of metal and plastic parts

The molding is a process for the combination of several materials on a molded part in the same mold. Using multiple materials brings to the part new features.

The purpose of molding can be molded insert to obtain a protection or a plastic part in 2 colors by a combination of two materials with a rigid part and a soft part.

This process provides you an optimized cycle time, eliminating the risk of contamination between the different operations and the adhesion between the different materials is perfectly respected.

The overmolding process is carried out in our local either manually or robotically by 2 presses operating in “tandem”.

Polymers

 

Materials 100% or partially bio-based, recycled natural fibers and loaded:

We now offer a real expertise on alternative materials to petro-sourced products (PP – PA – PC …). We inject material 100% or partially bio-based, recycled, and loaded with natural fibers in industrial quantities the following materials:

biodegradable - CEVA Technologies - injection - bi injection - tri injection
biomaterials - CEVA Technologies - injection - bi injection - tri injection

* Polymers loaded in natural fibers such as hemp, flax, miscanthus, the vine shoot or mineral filler such as recycled oyster shell.

These materials are used to design parts or technical applications in various industries.

CEVA Technologies advise you on your choice of materials about the usefulness of your parts.

The heart of our business involves injecting thermoplastics to achieve technical and appearance parts. Specialist in injection molding of thermoplastic materials, we produce technical and appearance parts in small, medium and large series.

We are able to treat all existing thermoplastic materials:
