Zubler Handling


“Altefco is con­ve­ni­ent­ly loca­ted near us, allo­wing us to deli­ver and pick up our machi­ne parts for coa­ting in a fle­xi­ble man­ner. As a tail­or-made machi­ne manu­fac­tu­rer for the pla­stic indu­stry, we often need to react quick­ly. When time is of the essence, we recei­ve sup­port from Altefco. They have our back and meet the dead­lines. And – we have prac­ti­cal­ly zero defects.”

Effi­ci­ent and high­ly pre­cise
Tail­or-made machi­nes from Zubler Handling

The pro­duc­tion systems in the pla­stics indu­stry are high­ly auto­ma­ted. This extends far bey­ond the actu­al pro­duc­tion of injec­tion moul­ded parts. Post-pro­duc­tion pro­ces­sing in par­ti­cu­lar is extre­me­ly com­plex. Zubler Handling AG from Uzwil SG is a spe­cia­list in manufacturing tail­or-made machi­nes and excels in this niche.

“Injec­tion moul­ded parts are remo­ved from the mould, mea­su­red, inspec­ted, stacked, packa­ged and label­led on the tail­or-made auto­ma­ti­on systems from Zubler Handling,” explains Remo Mül­ler, Head of Purcha­sing and Manufacturing at Zubler Handling AG. Among the pla­stic pro­ducts pro­ces­sed with the company’s machi­nes are, for exam­p­le, pre­cis­i­on parts for medi­cal tech­no­lo­gy, pack­a­ging for the food indu­stry and much more.

The machi­nes come into direct cont­act with the finis­hed pla­stic parts and one of the chal­lenges in post-pro­ces­sing is handling the parts, which are often only mil­li­me­t­res in size, wit­hout dama­ging them during mecha­ni­cal con­vey­ing. Fur­ther­mo­re, pla­stic parts for labo­ra­to­ry tech­no­lo­gy are pro­du­ced in cle­an­rooms, which requi­res addi­tio­nal requi­re­ments. Abra­si­on, for exam­p­le on con­vey­or belts and grip­per arms, must be avo­ided at all costs. The­r­e­fo­re, various parts that come into cont­act with the pla­stic parts requi­re very good slip pro­per­ties. “Ever­ything must run cle­an­ly and pre­cis­e­ly,” explains Remo Mül­ler.

High pro­duc­ti­vi­ty requi­red
Zubler Handling machi­ne parts are coa­ted with ALTEF® or EMATEF®, depen­ding on the appli­ca­ti­on and func­tion of the com­po­nent. EMATEF® is main­ly used for parts whe­re supe­ri­or slip pro­per­ties are requi­red. It pro­vi­des a low rough­ness value, eli­mi­na­ting the need for expen­si­ve finis­hing (poli­shing). “We have a long-stan­ding col­la­bo­ra­ti­on with Altefco in this field and are very satis­fied,” says Remo Mül­ler. “As a tail­or-made machi­ne manu­fac­tu­rer, we often need to react quick­ly. When the pres­su­re is on, Altefco is the­re to back us up. They are very relia­ble.”

The pla­stics indu­stry is high­ly com­pe­ti­ti­ve and Zubler Handling ope­ra­tes inter­na­tio­nal­ly. The Uzwil-based com­pa­ny offers its cus­to­mers a com­pre­hen­si­ve ser­vice, from engi­nee­ring through to com­mis­sio­ning, main­ten­an­ce and repairs. “Effi­ci­en­cy and pro­duc­ti­vi­ty in the manu­fac­tu­re of our machi­nes is essen­ti­al for us to remain com­pe­ti­ti­ve,” says Remo Mül­ler. “Altefco also sup­ports us on this front. The com­pa­ny meets dead­lines and deli­vers the best qua­li­ty. And we have vir­tual­ly zero rejects from the coa­ting pro­cess.”

Suter Industries

“Suter Industries sup­plies anti-hop­ping clut­ches to race teams, motor­bike manu­fac­tu­r­ers and dea­lers world­wi­de. They are cha­rac­te­ri­sed by a high degree of hard­ness and bond strength – and they look beau­tiful. Altefco is a tech­ni­cal lea­der in aluminium coa­ting and ANOTEC® meets our high requi­re­ments. We are par­ti­cu­lar­ly impres­sed by the dimen­sio­nal accu­ra­cy, the con­sist­ent­ly high qua­li­ty and the ele­gant visu­al appear­ance of our finis­hed clut­ches.”

Ele­gant and safe
Motor­bike clut­ches from Suter Industries

The com­pa­ny Suter Industries from Tur­ben­thal ZH has been using ANOTEC® from Altefco for coa­ting motor­bike clut­ches for over 20 years. Their flag­ship pro­duct, the “SUTERCLUTCH”, is extre­me­ly popu­lar with racers, motor­bike manu­fac­tu­r­ers and motor­bike enthu­siasts ali­ke owing to its sophi­sti­ca­ted engi­nee­ring.

Peo­p­le who ride motor­bikes do so out of pas­si­on. They take spe­cial care of their own bike, becau­se it should offer maxi­mum safe­ty on the road and also look gre­at. Suter Industries, a vehic­le sup­plier in the motor­bike, bicy­cle and ener­gy sec­tors, is a manufacturing com­pa­ny with 45 employees. The com­pany­’s best-known pro­ducts are anti-hop­ping clut­ches for motor­bikes, of which it pro­du­ces seve­ral thou­sand per year. Suter Industries sup­plies racing teams, various motor­bike manu­fac­tu­r­ers and end cus­to­mers.

Long­stan­ding col­la­bo­ra­ti­on
Suter Industries has reli­ed on Altefco as a coa­ting part­ner in this area for over 20 years. “Altefco is the tech­ni­cal lea­der when it comes to aluminium coa­tings,” sagt Roger Sut­ter, pro­duc­tion mana­ger at Suter Industries. The col­la­bo­ra­ti­on deve­lo­ped, howe­ver, also becau­se of the geo­gra­phi­cal pro­xi­mi­ty: “For us, it is easy to deli­ver and coll­ect the parts in near­by Thur­gau.” Altefco is also unri­val­led in terms of pro­ces­sing speed: “A job usual­ly takes a week – if it’s urgent, Altefco can do it in two days.”

Con­si­stent qua­li­ty
Hard­ness and bon­ding strength are cru­cial for the coa­ting of motor­bike clut­ches. That is why Suter Industries has opted for hard anodising with ANOTEC®. The pro­cess invol­ves app­ly­ing a lay­er of aluminium oxi­de, which pro­tects the clutch from wear and cor­ro­si­on. The sur­face of the base mate­ri­al is trans­for­med in the pro­cess. This means that half of the coat thic­k­ness ‘grows’ into the base mate­ri­al, so that a stan­dard thic­k­ness of 40 µm (40/1000 mil­li­me­t­res) results in an appli­ca­ti­on of 20 µm. “We are par­ti­cu­lar­ly con­vin­ced by the dimen­sio­nal accu­ra­cy,” says Roger Sut­ter. “Altef­co’s coa­tings are always exact­ly the same thic­k­ness. We can rely on that.”

The­re is ano­ther good rea­son why Suter Industries works almost exclu­si­ve­ly with Altefco for its motor­bike clut­ches: “Our cus­to­mers want their motor­bike to look gre­at,” says Roger Sut­ter. “An ele­gant appear­ance is the­r­e­fo­re par­ti­cu­lar­ly important to us. ANOTEC® enables us to achie­ve this as well.”


“We manu­fac­tu­re machi­nery for the cho­co­la­te indu­stry. The core com­pon­ents of our systems are trea­ted with an ALTEF® coa­ting, which makes them har­der and more scratch-resi­stant. Addi­tio­nal­ly, the sur­face gains bet­ter slip pro­per­ties. Altefco pro­vi­des excep­tio­nal­ly good con­sul­ting ser­vices. They help us when­ever neces­sa­ry and respond very quick­ly to inqui­ries. Adhe­rence to deli­very dates and con­si­stent qua­li­ty are fur­ther rea­sons why we have cho­sen Altefco.”

Robust and ver­sa­ti­le
Cho­co­la­te pro­duc­tion lines from TRIKNO AG

In cho­co­la­te pro­duc­tion, ver­sa­ti­li­ty is the name of the game. TRIKNO AG from Fel­ben-Well­hau­sen spe­cia­li­ses in cho­co­la­te and con­fec­tion­ery machi­nes and stands out for its cus­to­mi­sed solu­ti­ons. The Thur­gau-based com­pa­ny reli­es on Altefco for its aluminium coa­ting.

The pro­duc­tion of a pra­li­ne is a high­ly com­plex mat­ter. The initi­al­ly liquid cho­co­la­te goes through a who­le series of pro­duc­tion steps on its way to beco­ming a finis­hed con­fec­tion. Start­ing with the pro­duc­tion of the cho­co­la­te mass, to the moul­ding of hol­low forms, to the brief stop on a vibra­ti­on table for con­si­stent shell thic­k­ness, to pou­ring in the fil­ling, to pre­hea­ting again under a bon­net, and final­ly to gar­nis­hing with nuts or other deli­ca­ci­es. TRIKNO AG spe­cia­li­ses in such pro­duc­tion lines and is repre­sen­ted with its equip­ment at almost all the major cho­co­la­te brands in Switz­er­land. “We cater to the indi­vi­du­al needs of our cus­to­mers and also offer pro­to­ty­pe cons­truc­tion,” says Joël Michel, Head of Purcha­sing at TRIKNO AG.

Cus­to­mer from the very begin­ning
For more than ten years, TRIKNO cho­co­la­te pro­duc­tion line machi­ne parts have been trea­ted with aluminium coa­tings. “We have alre­a­dy had over 6800 parts coa­ted at Altefco. We opt for ELOX and ALTEF® coa­tings,” says Joël Michel. The core parts of the pro­duc­tion lines are coa­ted with ALTEF® – this makes them har­der and thus more scratch-resi­stant. It also increa­ses the slip pro­per­ties of the cho­co­la­te mass on the sur­face. Exter­nal machi­ne parts are given an ELOX coat – making them more cor­ro­si­on-resi­stant and visual­ly more appe­al­ing.

For the ulti­ma­te cho­co­la­te expe­ri­ence
It is par­ti­cu­lar­ly important for TRIKNO that both types of coa­ting meet food safe­ty stan­dards: “We have to com­ply with many requi­re­ments in terms of food safe­ty. The end pro­duct must not be con­ta­mi­na­ted. Altefco’s pro­cess puts us on the safe side,” explains the cho­co­la­te pro­duc­tion expert. “Ano­ther advan­ta­ge the coa­tings offer is extra pro­tec­tion when clea­ning the machi­nes.”

Machi­nes are clea­ned often, and when a pro­duct chan­ge is due, cho­co­la­te pro­du­cers have to make sure that not even the smal­lest rem­nant of the pre­vious pro­duct is left in the machi­ne.

A part­ner­ship on equal terms
“Altefco’s aluminium coa­tings are not just sur­faces, they bond with the mate­ri­al under­neath and as a result are very dura­ble,” says Joël Michel.
In addi­ti­on to pra­li­nes, a wide varie­ty of cho­co­la­te con­fec­tions can be pro­du­ced on TRIKNO lines – from simp­le cho­co­la­te bars to Easter bun­nies and from cho­co­la­te bana­nas through to truf­fles or bis­cuit fil­lings. “Altefco has been fami­li­ar with our parts for a very long time and they have given us some good tips. We also get an imme­dia­te respon­se when we have que­sti­ons.”
