An in­ter­na­tion­ally proven range of hard wear­ing cast polyamide en­gi­neer­ing plas­tics from the Wear­lon range of Cut To Size Plas­tics is for­mu­lated to re­duce wear and main­te­nance and en­hance safety in a wide range of ma­chin­ery and in­dus­trial equip­ment.

The LiNNOTAM range of cast polyamides from in­ter­na­tional man­u­fac­turer and fab­ri­ca­tor of en­gi­neer­ing plas­tics Licharz is a mem­ber of the Wear­lon fam­ily of en­gi­neered plas­tics suit­able for OEM use and metal re­place­ment in ap­pli­ca­tions in­volv­ing trans­mis­sion of me­chan­i­cal force and min­imis­ing fric­tion.

Ap­pli­ca­tions where the Wear­lon fam­ily of­fers op­ti­mum ben­e­fits in­clude cranes and lift­ing equip­ment, ma­te­ri­als han­dling ma­chin­ery in­clud­ing con­vey­ors as well as fixed and mo­bile plant ex­tend­ing from min­eral pro­cess­ing equip­ment and power gen­er­a­tion tech­nol­ogy (in­clud­ing ten­dons in wind­mills) through to min­ing draglines, heavy trans­port, im­ple­ments, con­struc­tion equip­ment and in food pro­cess­ing and pri­mary prod­uct pro­cess­ing equip­ment in­clud­ing tim­ber and pa­per.

Avail­able in var­i­ous grades for dif­fer­ent pur­poses, Wear­lon LiNNOTAM metal-re­place­ment ma­te­ri­als of­fer es­pe­cially long ser­vice lives and are easy to ma­chine to cus­tom-fab­ri­cated shapes,” says Cut to Size NSW Man­ager Pat Flood. Cut to Size man­u­fac­tures com­po­nents such as sheaves, rollers, gears and wear com­po­nents for ap­pli­ca­tions across Aus­trala­sia from its Head of­fice in Syd­ney, where fa­cil­i­ties in­clude CNC ma­chin­ing fa­cil­i­ties cou­pled with Gibb­sCAM and Solidworks soft­ware.

“Steel wire ropes are im­por­tant and highly stressed ma­chine el­e­ments in force trans­mis­sion and con­vey­ing tech­nol­ogy. In many cases, large plants de­pends on their func­tion­ing not only for ef­fi­ciency but also safety. Wear­lon can ex­tend life­span and en­hance safety by re­duc­ing main­te­nance and preserving struc­tural in­tegrity for longer,” said Flood.

Ben­e­fits

En­gi­neer­ing plas­tics such as Wear­lon of­fer: • Rope-con­serv­ing elas­tic­ity. • Com­pres­sion fa­tigue strength. • High wear re­sis­tance. • Tough­ness, also at low tem­per­a­tures. • Re­sis­tance to lu­bri­cants. • High re­sis­tance to weath­er­ing ef­fects.

“Wire ropes are stressed by f luc­tu­at­ing forces, by wear, by cor­ro­sion and by ex­treme forces. Ropes that run over sheaves made from metal­lic ma­te­ri­als are sub­ject to high stress due to the sur­face pres­sure that oc­curs be­tween the rope and the groove. When the rope rolls over the sheave, only the outer strands lie on the groove. The re­sult of this is wear in the form of in­di­vid­ual strands break­ing or, more se­ri­ous, rope break­age,” says Flood.

“Sheaves made from Wear­lon pre­vent this due to their elas­tic be­hav­iour. The pres­sure be­tween the rope and the roller in the com­bi­na­tion steel rope/polyamide roller is around 1:10 com­pared to steel rope/steel roller. This can be at­trib­uted to the visco-elas­tic be­hav­iour of polyamide. It is not just the outer strands that lie in the groove, but al­most the whole pro­jected strand width. This re­duces sur­face pres­sure be­tween the rope and the roller and con­sid­er­ably ex­tends the life of the rope.”

The cast polyamides of the LiNNOTAM mem­bers of the Wear­lon fam­ily can be pro­duced as semi-fin­ished prod­ucts or near net shape com­po­nents and are vir­tu­ally free of in­ter­nal

stress. Cut to Size of­fers a large se­lec­tion of shapes, weights and di­men­sions.

Cut to Size Plas­tics Pty Ltd has been sup­ply­ing En­gi­neer­ing Plas­tics to Aus­tralian and

In­ter­na­tional cus­tomers for over 35 years. The com­pany is com­mit­ted to meet­ing Aus­tralian and In­ter­na­tional Qual­ity Stan­dards and to work­ing within the guide­lines is­sued by State workcover au­thor­i­ties.

The com­pany holds ex­ten­sive stocks of Ny­lon, LiNNOTAM GLIDE, Del­rin, Ac­etal, Te­flon and UHMWPE com­bined with HDPE, PVC and Polypropy­lene to com­ple­ment ser­vice to in­dus­try. Cut to Size also has ac­cess to the most ad­vanced en­gi­neer­ing plas­tics world­wide.

The com­pany will cut it, rout it, bend it or ma­chine it, all to in­di­vid­ual spec­i­fi­ca­tions. The com­pre­hen­sive CNC ma­chin­ing fa­cil­ity at Yen­nora, cou­pled with Gibb­sCAM and Solidworks soft­ware make it easy to deal with us, prom­ises the com­pany. “Your draw­ings go into our com­puter – then to the CNC ma­chines.”
