RÁK Antenna Gyártó Kft.

Our main activities:Injection moulding, painting and lacquering of plastic parts in mass production.

We customise the following services to our customers’ expectations:

Product design, tool making, injection moulding, painting, lacquering, developing biodegradable, compostable plastic.

The original firm was founded by Árpád Rajnai in 1968.We have been manufacturing car equipment since 1980.Our company has been 100% family owned since then.

We have been a supplier to the automotive industry since 1992.

Currently we operate from a plant spanning 5100 square meters and accommodating 150 employees.

RÁK Antenna Gyártó Kft.Our competitive edge

We are able to cover the whole manufacturing process from plastic injection moulding to painting and lacquering of plastic parts, all of this within the company premises.When we start moulding, we already take the aspects and requirements related to the subsequent painting into consideration.

Since we offer a one-stop shop there is no delivery cost, risk of damage or time wastage and no need to deal with additional storage costs in between the various stages of manufacture.

We guarantee the perfect match between plastic and painting materials.This way we can reduce quality problems to almost zero: there is no blobbing, poor priming orpeeling.

We can undertake the painting and lacquering of parts in the required number of layers using our painting robots in a clean room and a closed painting system. With this technology we can achieve an extraordinarily resistant, long-lasting and aesthetic painting thanks to the 2-6 layered wet-on-wet painting technique.


Our quality certifications:

ISO 9001ISO 14001

At Hungarian Suzuki Co. Ltd., we won the title of „The supplier of the year” three times for our outstandingperformance.

We also received a „Kaizen” prizefor our oustanding cost cuttingactivities.

Injection moulding of plastic products with a weight of 10-2800 cm3(up to 650 tons of clamping force).

The plastic types we use:PE, PP, PS, ABS, PA/ABS, PC, PC/ABS, PC/PBT, PA 6, PA 6.6, POM, PPS, PLA


PAINTING PLANT:− painting of plastic, glass, metal− painting with the required number of layers (even 6-8), even in a wet-on-wet

system (also without intermediate drying!)− drying technology: 40- 125 °C− 6-axis painting robots− the latest Japanese spraying technique (ANEST IWATA)


We can undertake the painting and lacquering of parts in the required numberof layers using our painting robots in a clean room and a closed painting system.

With this technology we can achieve an extraordinarily resistant, long-lastingand aesthetic painting, also in the case of exterior products, thanks to the 2-6 layered wet-on-wet painting technique.


Rock wool baking:

We have been manufacturing silencer pads from rock wool for vehicle exhaust systems for more than 10 years.Thus far we have produced in excess of 4,5 million pieces.


Ultrasonic welding (20 KHz)

Joining plastics without any intermediate material (like glue).Metal installation with ultrasonic welding (Insert).Welding of plastic parts together, installation of steel crews

Example below: tailgate handle of Suzuki Ignis


We also actively participate in the product development, design and theproduction of manufacturing tools.

We have our own tool maker and tool maintenance workshop.

Our tool manufacturing capability: 1000 x 500 mm.For larger tools, we are in close contact with external tool maker companies.


ValVac vacuum sewage valve

The ValVac TM2 vacuum sewage valve is a product we proudly developed in-house. In the course of its development we have pioneered a valve system that drains communal wastewater from apartment complexes using a vacuum. This system is installed in locations where - due to the field conditions - the emerging wastewater cannot be drained through gravity.

We – thanks to our track record as automotive suppliers - pay close attention to detail in the manufacturing and assembly process. We provide a 2-year guarantee for the quality of our valves. The towns of Verpelét, Nick, Mártély, Szentistván, Mezőkeresztes and Alattyán have installed our valves during the construction of their sewerage network. The valves in vacuum sewer systems will be replaced with the valves manufactured by us in another 23 settlements.

ValVac TM-2


We use ARBURG PROFOAM technology on 3 machines

The essence of this is that by closing the end of the cylinder and the granule feeder "hopper" in the cylinder performing the melting and forwarding of the plastic, the injection moulding, the entire area of the pulley can be placed under a gas pressure of 10-50 bar.

N2, or C02 are the most commonly used gases. The gas is fed into the plastic raw material and the end-product is a gas-blended plastic product.


Advantages:

− less use of plastic,− 10-30% reduction in the weight of parts,− elimination of shrink-marks,− elimination of warpage,− less shrinkage of parts,− usable larger and variable wall thickness, − need lower clamping force,− reduces the degradation of the raw material in the cilinder.− in case of a fiber-reinforced raw material it does not break the fibers to

the same extent as the gas foaming technology applied so far (e.g. MuCell)

In 2015 we became active in the development of PLA biologically degradable plastic with a focus on heat resistance, flow properties, flame retardancy, fiber-reinforced ability, impact resistance, foamability, glass transition, paintability and sunlight resistance.


RÁK Antenna Gyártó Kft.CompoundingCompounding for improve the material properties:

• Modular twin screw extruder with 26 mm screw diameter,• With one main and four sidefeeder and one liquid dosing point,• high efficient mixing at five zone,• Maximum capacity: 80 kg/h,• Special cooling technique: in N2 gas, or in cooled and• dryed air to avoid hydrolytic degradation.


3D filament extrusion:

• 1.75 mm and 2.85 mm diameter filaments with +/- 0,02mm tolerances.• Biodegradable raw material from PLA.• Quality controll with digital laser measurement register• Automatic filament accumulator for continuous production.


We produce filaments for HOME and INDUSTRIAL usagetoo.

Our filaments are characterized by excellent, consistentquality. We are monitoring the product quality in-line and ourlaboratory too.

Our products have one of the best parameters available onthe market. On the one hand, we have formulated forourselves that the filament diameter tolerance of ourfilaments is made on the market ±0.05 mm instead of ±0.01mm.

It is also important fact, that the ingredients of our PLA filaments are food-approved.

Xenon chamber

The Q-SUN Xe-3 chamber is an excellent research, developmentand quality assurance tool in which it can be examined how thesamples will behave when exposed to sunshine, temperature andmoisture effects. The floor space of the 451 mm x 718 mmspecimen holder is nearly three times the size of the previousQ-SUN Xe-1.

Cycles can be defined to WAL-1 and WAL-2 too (SES N 3293), The parameters can be switched between:i.e. light and dark periods, periods withlow and high temperature, low and high humidity, dry andsprayed (rain imitating) periods can be alternated.


Some characteristics of the equipment are:

- The operating parameters can be programmed independently ofeach other, in a wide range. Cycles can be defined within them.- the light is provided by 3 pcs of full-spectrum Xenon lamps- The light is transferred to the samples through a removable filter,optionally through a sunlight, indoor or extended UV-filter.- The intensity of light is controllable.- The temperature is controllable.- The humidity is controllable.- In the desired times, water spray can be introduced into thesample space.- The above operating parameters can be independently controlled


DSC – MeasurementDifferential Scanning CalorimetryWhen a material undergoes phase transition or chemicaltransformation (e.g. melting, evaporation, crystallinemodification, chemical reaction), it submits or takesup heat.

Certan transitions occur when the temperature changesand the purpose of differential scanning calorimetry(DSC) is to determine the temperature at which thesetransformations occur and what thermal effects areassociated with these transitions.
