44NTX
Description
The 44 NTX toggle mechanisms are mounted on massive toggle brackets, which are bolted to the platen of the machine. On the opposite side from the table, the four toggle brackets are joined together by a heavy ring. The resulting assembly is extremely rigid. Deflection under load is minimal.
The 44 NTX machine is capableof reaching a dry cycle speed of 3,600 cycles per hour and accepts tooling designed for Techmire 44NT and 44H series machines.
The NTX Series is Techmire’s “premium” range of zinc and lead machines suitable for the widest range of applications in today’s demanding environment, and incorporates the latest advances in multiple-slide die-casting technology. The first NTX machine was introduced in 1999. The NTX Series features high capacity clamping systems, which are extremely rigid, and permit the use of greater metal pressures and injection velocities compared to the NT Series, resulting in superior surface finish and part density.
The NTX Series is complementary to the NT Series, and significantly increases the range of components that can be cost-effectively produced on Techmire machines.
