RTM press systems from Langzauner:
The expert in Resin Transfer Molding
Langzauner offers its customers Resin Transfer Molding (RTM) press systems as a one-stop-solution. The importance of RTM processes in lightweight engineering continues to grow across a wide range of production areas. Carbon fiber-reinforced polymer (CFRP) and other fiber composites are becoming increasingly vital materials not only in the aviation industry and automotive sector. – Langzauner offers RTM press systems that are 100% oriented towards individual production processes.
The advantages of Resin Transfer Molding
RTM processes have established themselves in lightweight engineering because they deliver advantages in the production processes and in the quality of the parts:
- ideal solution for automated processes
- relatively short cycle times, which can be further optimized through gap impregnation or gap injection
- low clock cycles and high output rates
- parts with a high-quality finish and excellent strength
- production of parts with a high fiber volume content
- reproducible, safe production processes
Langzauner is your partner for all popular RTM processes:
When low clock times and high output rates are required, the composite industry very often uses RTM processes. Langzauner offers press systems for all popular RTM processes:
RTM process | Exact designation | Range of applications |
---|---|---|
HP-RTM | High Pressure Resin Transfer Molding | High Pressure RTM is the ideal application for shorter cycle times in the production of CFRP parts. The higher pressure in both the mixing head and the mold sharply reduces the cycle times for larger parts. |
SQ-RTM | Same Qualified Resin Transfer Molding | SQ RTM is ideal for the production of large close-contour parts with a high degree of complexity. Ideal for the manufacture of parts in the aviation industry. SQ Resin Transfer Molding achieves a significant reduction in costs compared to the production of parts in autoclaves. |
C-RTM | Compression Resin Transfer Molding | Compression RTM enables the series production of CFRP parts with a high fiber volume content in short cycle times. A lower injection pressure is offset by the closing force of the press system. |
L-RTM | Light Resin Transfer Molding | Light RTM is an injection process that uses a sealed mold. The resin is injected under low pressure with vacuum assistance. LRTM press systems are especially suited for the production of complex parts in the caravan and automotive industry. |
