Technology

The main profile of our company is injection moulding, painting and varnishing plastic parts.

OUR MACHINE PARK

We have 17 pc of plastic injection moulding machines of Arburg, Battenfeld, Engel types.
Arburg ProFoam technology.

INJECTION MOULDING

We can undertake to manufacture and injection moulding plastic parts (max. 500 t locking force). Our machinery is of state-of-the-art technology. They are suitable for injection moulding products weighed from a couple of grams to parts of 1500 g (this equals to a product of cc. 1100 cm2 projected surface).

In case of several component products (steel, plastic, combined) we can undertake manual assembling. We make the templet and the special tools necessary for assembling.

Naturally we are able to make inserts as well (e.g. inserting steel into the injection moulding product). We also have adequate cutting and pressing machines (up to 25 t pressing force) to prepare the component to be inserted. Using our excenter presses we can undertake to manufacture parts from brass, bronze and steel ribbons and to machine steel parts up to 20 mm diameter.

Since we are able to carry out all services within the company we can immediately deal with problems arising from quality and transport and can reduce them to almost zero. All this is done at highly competitive prices.

TYPES OF PLASTIC WE ARE USING
PE, PP, PS, ABS, PA/ABS, PC, PC/ABS, PC/PBT, PA 6, PA 6.6, POM, PPS, PVC, PLA…
Our main products are internal and external covers for passenger cars and we also manufacture parts for fitness machines.

ARBURG PROFOAM TECHNOLOGY

Lightweight construction: new ProFoam physical foaming technique

ARBURG demonstrated a new physical foaming technique at the Fakuma 2015. In the ProFoam process, the material is initially mixed with a liquid propellant in a granulate lock between the material reservoir and feed. Glass-fibre reinforced plastics can be processed without additional shearing.

Cost savings, increased efficiency, conservation of resources and CO2 emissions: lightweight construction as a “problem solver” is a key topic for the future in numerous industries. The aim is to reduce part weights, while maintaining or improving mechanical properties. Innovative injection moulding processes are required for this purpose.

ARBURG offers ProFoam for the physical foaming of thermoplastics. The plastic granulate is mixed with a gaseous blowing agent in a granulate lock upstream of the injection unit. This means that glass-fibre reinforced plastics can be processed without additional shearing. Ideal prerequisites for lightweight construction.
In case of PA6 20% glass-filled material 30% weight reduction can be achieved.

Highlights:

– Lightweight construction for weight reduction: forming the finest cell structures in the component, saving material
– Homogeneous foam structure: lighter moulded parts with fewer sink holes, less shrinkage and distortion
– Foaming of glass-fibre reinforced plastics: normal screw geometry without a mixer
– Efficient foaming technology: simple process control with gaseous blowing agent, machines can be used without restrictions for conventional injection moulding

PAINTING, VARNISHING

We can undertake the painting and varnishing of parts in the required number of layers in our closed paining system.
We started our brand new painting plant manufactured and commissioned by a German company in 2008 which represents the latest technical standards.

Painting is carried out in a closed system, in a continuously clean area. Due to the design of the painting plant unlimited layers of paint can be applied on the parts without having to interrupt continuous paining even in a wet-wet system.

In case of plastic parts (with the exception of coating ABS base material) it is necessary to apply priming paint.Colour will be the following layer.The third or the fourth layer of varnish will protect the coating from the harmful effects of strong sunlight, chemicals and the effects of mechanical usage. Such demand has also risen in the market to apply 6-8 layers of varnish onto the surface of the part to achieve a special aesthetic effect, e.g. onto the internal decorative parts of luxury cars. In order to avoid possible damages within technology and to achieve a more productive process transportation of parts is carried out on a lower conveyor line. Even layer thickness of paint and constant colour fidelity can be ensured by applying the paint using automatic spraying technology. During spraying unutilized paint mist is captured and cleared away from the spraying area using water curtain running underneath, at the back and on the sides, ensuring the cleanness of the air in the spraying area, the unpolluted surface of the parts and the perfect quality.

Our drying equipment used for drying the layers of paint is suitable for drying even at an object temperature of 125°C. We can use any kind of painting systems. We can use painting systems of air-drying, drying at 60, 80, 90, 100, 110, 125°C, ensuring the formation of a paint layer of the perfect hardness.

We use a semi-automatic machine to make screen-painting.
Utilizing our technology we can paint high series of parts in a very cost-effective way.

ULTRASONIC WELDING (20 KHz)

Inserting metal inserts.
Instead of gluing two plastic parts together we join them using ultrasonic welding and we also insert steel bolts into plastic which is also more durable than gluing.
E.g. the back door handle of Suzuki Ignis is fastened to the back door by 4 pc of steel bolts. The 4 pieces of steel bolts are heated by ultrasonic vibration for 1 or 2 seconds and by melting the plastic it melts into the plastic after which the plastic will stiffen resulting in safe jointing. Using a technology of 20 KHz we are able to weld a wide scale of surface sizes.

AERIAL, AUTO AERIAL

We can produce auto aerials up to 500,000 pieces per year.
We have been manufacturing car aerials since the 1980. For more details please see Aerials in Our Products page.
We also serve individual customers from our store.

ROCK WOOL BAKING

We undertake the production of parts made of rock wool using baking technology.

Additional heating units are used in the case of such vehicles where the heat of the engine does not heat the passenger cabin or in the case of standing heaters. We produce rock wool silencer inserts into the insert of the exhaust silencer of such additional heating units.

VACUUM VALVE

We can undertake the production and installation of vacuum valves to settlements operating a vacuum sewage system.

ValVac TM2

As a result of our 7-year long development our ValVAc TM2 vacuum sewage valve has been introduced to the domestic market and passed all tests perfectly. During development such valve system was designed that uses vacuum to drain communal waste water from the apartments. This system is installed to such places where gravity draining of the generating waste water is not possible due to ground reasons.

The whole vacuum valve is our design and all the die-casting, bending and cutting tools were manufactured in our own tool-making shop. Installation is carried out with great attention and precision – since we are a supplier of the automotive industry. We give a guaranty period of 10 years for the quality of our valves. Presently our valves operate at the following settlements: Verpelét, Nick, Mártély, Szentistván, Mezőkeresztes, Alatatyán, Törtel.

TOOL DESIGN:

We also take an active part in product development and in developing, designing and manufacturing tools.

We have our own tool manufacturing and tool maintenance workshop.

Our tool manufacturing capacity is 1000×500 mm. If larger tools are needed, we co-operate with tool suppliers.
