From uni­que che­mi­stry to machined parts

HIGH-PER­FOR­MANCE COM­PO­SI­TES FOR ALL DUTIES

Com­po­si­te mate­ri­als are used in many indus­tri­al app­li­ca­ti­ons to rein­for­ce com­pon­ents or struc­tu­ral ele­ments. For this pur­po­se, they must fea­ture very uni­que mecha­ni­cal, ther­mal and electri­cal pro­per­ties. We achie­ve and com­bi­ne the­se in such a cle­ver way that no requi­re­ments are left unful­fil­led. The result: our pro­ducts deli­ver top per­for­mance even in the most chal­len­ging environments.

No mat­ter what par­ti­cu­lar com­po­si­te mate­ri­al you need: Our R&D engi­neers will find the per­fect solution.

360° Exper­ti­se

Engi­nee­ring from A to Z

Our experts can hand­le the ent­i­re value chain — from the deve­lo­p­ment of resin for­mu­la­ti­ons and manu­fac­tu­ring pro­cess to the machi­ning of rea­dy-to-use components.

 

Com­po­si­tes solu­ti­ons — fit for purpose

The chemistry is right

The che­mi­stry is right 

Our che­mi­stry experts are con­stant­ly inven­ting new resin for­mu­la­ti­ons. In com­bi­na­ti­on with the latest pro­duc­tion pro­ces­ses, this results in a wide ran­ge of epo­xy, phe­n­o­lic, poly­es­ter and sili­co­ne resins. An excel­lent back­bone for lami­na­tes with the hig­hest fle­xi­bi­li­ty and excel­lent tech­ni­cal properties.

Advanced impregnation technologies

Advan­ced imp­reg­na­ti­on technologies 

In our modern pro­duc­tion faci­li­ties, we use a wide ran­ge of imp­reg­na­ti­on tech­no­lo­gies — e.g. dip coa­ting, kiss coa­ting or trans­fer coa­ting. Thanks to extra-wide imp­reg­na­ti­on lines and strict­ly con­trol­led cli­ma­tic con­di­ti­ons, we achie­ve maxi­mum pro­duc­ti­vi­ty and quality.

Molding in all dimensions

Mol­ding in all dimensions 

In our high-/low-pres­su­re and con­ti­nuous pres­ses, we pro­du­ce she­ets for a wide ran­ge of indus­tri­al app­li­ca­ti­ons. We also cover lar­ge for­mats up to 4 m² with pres­su­res of over 12 MPa. The she­ets are also avail­ab­le unma­chined as semi-finis­hed products.

Machining for any batch size

Machi­ning for any batch size 

Using sta­te-of-the-art mil­ling and grin­ding tech­no­lo­gy, we manu­fac­tu­re indi­vi­du­al parts and com­plex assem­blies from our com­po­si­te mate­ri­als. Our engi­neers sup­port you from pro­to­typ­ing to seri­al pro­duc­tion — to meet the hig­hest requi­re­ments for tole­ran­ces and qua­li­ty. Our sites are cer­ti­fied to sup­ply the aero­space and auto­mo­ti­ve industries.

Our varie­ty of products

Prep­regs

Von Roll has a broad port­fo­lio of pre-imp­reg­na­ted lami­na­tes with spe­ci­fic pro­per­ties for a wide ran­ge of indus­tri­al app­li­ca­ti­ons. This inclu­des stan­dard gra­des as well as high­ly spe­ci­fic solu­ti­ons for spe­cial requirements.

We set the hig­hest stan­dards through our own brands.

Vetro­ni­te® prep­regs can be used for a wide ran­ge of indus­tri­al app­li­ca­ti­ons whe­re resis­tance to mecha­ni­cal, electri­cal, and ther­mal stres­ses as well as fla­me retar­dant and che­mi­cal resistant pro­per­ties are required.

Vetrof­er­ri­te® prep­regs are used for com­pres­si­on mol­d­ed parts that requi­re magne­tic per­mea­bi­li­ty and high ther­mal and mecha­ni­cal sta­bi­li­ty, such as magne­tic slot wed­ges in electric motors.

Our Nxt­Gen epo­xy prep­regs are par­ti­cu­lar­ly sui­ta­ble for aero­space app­li­ca­ti­ons due to excel­lent mecha­ni­cal and FST properties.

  • Car­bon fab­ric: ECG Car­bon Prep­regs are used for indus­tri­al app­li­ca­ti­ons whe­re extre­me­ly high mecha­ni­cal pro­per­ties and a high elastic modu­lus are required.

She­ets

Lami­na­tes or laye­red com­po­si­tes are pro­du­ced using high and low pres­su­re technologies.

They are based on our prep­regs made of various rein­for­ce­ments (e.g. glass, car­bon, cot­ton, paper, ara­mid) and cor­re­spon­ding resin sys­tems (e.g. epo­xy, phe­n­o­lic, sili­co­ne). Our she­ets are used in a wide ran­ge of indus­tri­al, electri­cal and ther­mal applications.

Ther­mal insu­la­ti­on is essen­ti­al for the ener­gy effi­ci­en­cy, func­tio­n­a­li­ty, and ser­vice life of indus­tri­al pres­ses, but also for the pro­tec­tion of bat­te­ries for e‑mobility. Excel­lent heat dis­si­pa­ti­on is a key con­cern in many machi­nes and devices.

  • Vetro­therm® and Pami­therm® are cha­rac­te­ri­zed by their high ther­mal, che­mi­cal and pres­su­re resistance.

Machined parts

As a full-ser­vice pro­vi­der, our skills also inclu­de the pro­duc­tion of rea­dy-to-use com­pon­ents. Machined parts are tailor-made from our com­po­si­te mate­ri­als accord­ing to cus­to­mer spe­ci­fi­ca­ti­ons and tech­ni­cal drawings. They fea­ture the same excel­lent tech­ni­cal pro­per­ties as the semi-finis­hed pro­ducts. In our machi­ning com­pe­tence cen­ter, finis­hed parts are manu­fac­tu­red care­ful­ly and with very tight tolerances.

COM­PE­TENCE CEN­TER FOR MACHI­NING

Machi­ning is the fas­test and most effi­ci­ent way for seri­al pro­duc­tion of com­plex com­pon­ents made of laye­red com­po­si­tes. Take advan­ta­ge of the expe­ri­ence we have gai­ned from deca­des in machi­ning com­po­si­tes. Using the latest tech­no­lo­gies, we manu­fac­tu­re pre­cisi­on parts with the tigh­test tole­ran­ces at our Augs­burg and Brad­ford facilities.

With our wide ran­ge of self-deve­lo­ped resins and sub­stra­tes, we can pro­du­ce com­po­si­tes in an almost unli­mi­ted num­ber of com­bi­na­ti­ons. This varie­ty enab­les us to offer exact­ly the right mate­ri­al for every app­li­ca­ti­on. Just as we ser­ve our most deman­ding cus­to­mers in the aero­space, medi­cal, nuclear, auto­mo­ti­ve and electri­cal industries.
