Lettmann Manta L


Experience and passion meet high-tech

Sin­ce 2013, we have been respon­si­ble for the digi­tal imple­men­ta­ti­on and the upper ship design of various white­wa­ter kay­aks for the tra­di­tio­nal Ger­man brand Lett­mann from Moers.

The Lett­mann com­pa­ny has stood for pro­gress and inno­va­ti­on on the kay­ak mar­ket sin­ce 1965. The deve­lo­p­ment ran for almost 50 years on a purely manu­al basis. The ide­as and shapes were work­ed out from block goods with a high level of craft­sman­ship, mold­ed and fur­ther deve­lo­ped. The method allows a very direct rela­ti­onship to the pro­duct, but requi­res enorm­ous expe­ri­ence, manu­al skills - and a lot of time.

The manu­fac­tu­ring pro­ces­ses at Lett­mann essen­ti­al­ly include PE rota­ting, PE ther­mo­forming and vacu­um infu­si­on and pre­preg lamination.

With the tran­si­ti­on of the com­pa­ny into the next gene­ra­ti­on, the step into the digi­tal age beca­me neces­sa­ry in order to meet the expan­ded requi­re­ments for for­mal details and CNC-aided mold tool manufacture.

Dawn of a traditional brand into the digital age


PROJEKTER INDUSTRIAL DESIGN ente­red the deve­lo­p­ment in 2013 with its know-how in the are­as of lami­na­ting tech­no­lo­gy, mold making, 3D scan­ning and CAD sys­tems. The new models are now being suc­ces­si­ve­ly imple­men­ted digi­tal­ly and fur­ther deve­lo­ped and desi­gned using modern para­me­tric processes.

The pro­ces­sing by PROJEKTER INDUSTRIAL DESIGN includes the design of the non-hydrodynamically rele­vant are­as and the gene­ra­ti­on of 3D data in clo­se coope­ra­ti­on with Lett­mann, the con­ver­si­on of the data into a pro­duc­tion tool and the cor­re­spon­ding com­mu­ni­ca­ti­on with the toolmakers.

The first model "Gra­na­te XL" was pre­sen­ted in 2014 as a novel­ty at the Boot in Düs­sel­dorf. A lar­ge num­ber of other pro­jects fol­lo­wed, such as various high-quality ones car­bon padd­le and white­wa­ter access­ories. Most recent­ly, the cur­rent mas­ter­pie­ce of Lett­mann "Man­ta L" was also pre­sen­ted in Düs­sel­dorf in 2018. Fur­ther opti­miza­ti­on of the pro­ces­ses is plan­ned for the future – also with regard to new manu­fac­tu­ring processes.
