Resin Transfer Molding - Textile Scholar

 

Resin Transfer Molding Process:

 

1. In the RPM process, dry reinforcement is pre-shaped and oriented into skeleton of the actual part known as the perform which is inserted into a heated matched die mold.
2. The heated mold is closed and the liquid resin is injected.
3. The part is cured in mold.
4. Finally mold is opened and part is removed from mold.

 

Advantages of Resin Transfer Molding:

1. Large complex shapes and curvatures can be made easily
2. High level of automation
3. Simpler then in manual operations
4. Takes less time to produce
5. Low volatile emission
6. Cost effective
7. Low skill labor required

 

Disadvantages of Resin Transfer Molding:

1. Mold design is complex
2. Requires Mold-Filling Analysis
3. Fibre reinforcement may move during resin transfer
4. More expensive tooling than a compression mould
5. Slower production cycle than an injection tool
6. Manual handling of piston can be problem

 

Applications of Resin Transfer Molding:

1. Wind Turbine blade
2. Ship body
3. Car body
4. Truck panel
5. Aerospace parts
6. Bathtub, helmet
