Insulating material / Industrial plastic

Industrial winding core

リコセル
Thermosetting resin laminated tube with excellent mechanical strength is also used as industrial winding core of such as paper , film , fabric or foil.
RISHO is prepared for these application with various lineups.

 

 

■Merit
  • Reduction of defective winding.
  • Suitable for clean room use with dust-free property
  • Increase of winding amount and decrease of excange times of winding core.
  • Reduction of cost with repetitive use and contribution to environmental protection.

 

■Hybrid tube
  • Winding core with taugh inner layer and fine surface.
  • Various types of hybrid tube is available according to customer's use
  • This is a representative merit of useing laminated tube.

Inner : Paper/Phenolic
Surface : Glass/Epoxy

Inner : Glass/Epoxy
Surface : Paper/Phenolic

 

■Coupled tube
  • Coupled tube : Inner-tube according to winding shaft diameter and Outer tube according to customer's designing.
  • Weight reduction of winding core can be achieved.
  • Partial reinforcement with installing ribs is also available.

 

■Surface finish is also available
Such surface finish as Urethane paint application,Conductive paint application,Rubber lining or Surface machining is also abailable.

▲Urethane painting

▲Conductive painting

▲Rubber lining

▲Surface machining
