Resin Transfer Moulding

Resin transfer moulding (RTM) is applied for manufacture of parts where tighter tolerances, both side finish along with voidless construction of material is required. This moulding process makes use of closed mould system.

For manufacture of parts the two halves of the mould are first applied with release agent and uniform gel-coat layer and then laid up with special glass mat known as CFM or core mat. The two halves of mould are then closed with toggle clamps and vacuum applied to the mould with inbuilt vacuum minder. Resin is then forced into it with the help of a quick, semi-automated process. Once the requisite amount of resin is injected the mould is left for curing of the part for 30-45 minutes.

 

Benefits of RTM:

  • Requires minimum labour
  • Minimum wastage
  • Complete defense against air entering into the parts
  • Controlled and uniform thickness
  • Higher stiffness to weight ratio
 
 

At NTF we use RTM technology to develop superior quality and durable products. In the production process we useThermo set Reinforced as the raw material to produce:

  • Hard Tops
  • Spinners
  • Doors for Train
  • Roof (AC)
  • Panels
  • Cover - army boxes
  • Dash Boards
  • Consoles
