App­li­ca­tion-cen­te­red solu­ti­ons

Von Roll vanes and bla­des for vacuum pumps or air com­pres­sors fea­ture extre­mely low fric­tion, a low coef­fi­ci­ent of ther­mal expan­sion, very tight tole­ran­ces, mecha­ni­cal strength at ele­va­ted tem­pe­ra­tures, and che­mi­cal resistance.

Our Vetro­nite® vanes and bla­des are used in oil-lub­ri­ca­ted rotary vane pumps. In our high-end pro­ducts AR 600 P01, AR 600 T23 and ACG 600 T23, drop lub­ri­ca­tion is suf­fi­ci­ent to achieve very long ser­vice lives.

By con­trast, spe­cial Cane­vas­ite® gra­des ensure long ser­vice life in pneu­ma­tic motors and com­pres­sors — e.g. the pro­ducts FF 5964 and VRI-BAT for oil-lub­ri­ca­ted app­li­ca­ti­ons and FF-PTFE for dry-running.

High-pre­cision ball bea­ring cages — for example in den­tal drills — have to with­stand both vibra­ti­ons cau­sed by very high rota­tio­nal speeds as well as severe che­mi­cal stress due to sterilization.

We offer spe­cial cot­ton phe­n­o­lic pro­ducts (Cane­vas­ite® VRI-BAT or FF-5964) for ball bea­rings and meet the hig­hest requi­re­ments in terms of wear resis­tance and machi­na­bi­lity here — espe­cially for very small ball bea­ring cages.

To ope­rate the super­con­duc­ting magne­tic coils in a sta­ble state, nuclear magne­tic reso­nance spec­tro­scopes have to meet com­plex requi­re­ments. For example, the waste heat of the spec­tro­scope should be effi­ci­ently dis­si­pa­ted while the coils are kept at cryo­ge­nic tem­pe­ra­tures. Here, manu­fac­tu­rers of NMR equip­ment bene­fit from our machined parts made from Vetro­nite® EGS102 or Cane­vas­ite® PF CC 201.

Some gra­des of our Vetro­nite® pro­ducts have been spe­ci­fi­cally deve­lo­ped for app­li­ca­ti­ons at extre­mely low tem­pe­ra­tures. They can with­stand tem­pe­ra­tures as low as -270 °C. These solu­ti­ons have been in suc­cess­ful use for years already — and excel through their com­bi­na­tion of opti­mal func­tion and high performance.

Due to a spe­cial high-tem­pe­ra­ture resin, our stan­dard Vetro­nite® doc­tor bla­des fea­ture high mecha­ni­cal sta­bi­lity, great tem­pe­ra­ture, and wear resistance.

The bla­des are all-round talents and can be used at all posi­ti­ons of the paper machine — even in the chal­len­ging dry­ing section.

We adapt our hybrid bla­des to the exact requi­re­ments of our cus­to­mers by manu­fac­tu­ring bla­des with various num­bers of car­bon lay­ers. These pro­ducts are very per­for­mant, offer high mecha­ni­cal and che­mi­cal resis­tance and have excel­lent wear pro­per­ties — long dura­bi­lity with strong clea­ning performance.

Our range of high-per­for­mance car­bon bla­des for spe­cial requi­re­ments is cha­rac­te­ri­zed in par­ti­cu­lar by a very high mecha­ni­cal stiff­ness. This makes these bla­des ideal for app­li­ca­ti­ons that require maxi­mum clea­ning per­for­mance — such as in the dry­ing sec­tion of the paper machine. Through redu­ced con­tact pres­sure, they also enable a very eco­no­mi­cal ope­ra­tion of the machine.

Our abra­sive bla­des ensure maxi­mum clea­ning per­for­mance even in the most deman­ding sec­tions through the addi­tion of sui­ta­ble abra­si­ves. To ensure that our cus­to­mers do not have to make any com­pro­mi­ses, we manu­fac­ture the bla­des in all stiff­ness clas­ses — right up to an all-car­bon blade.
