88NTX
Description
The 88 NTX was developed for single cavity production of large surface area parts as well multiple cavity production of smaller components. It is the largest die-casting machine manufactured by Techmire. The 88 NTX machine is capable of reaching a dry cycle speed of 2,100 cycles per hour.
The 88 NTX is equipped with a quick die change system, which allow die changeover of a two (2) slide mold in as little as 15 minutes.
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.
