Hybrid Milling Machine Effectively Vents Gas

Matsuura Machinery USA Inc.’s Lumex technology makes effective mold/gas venting possible and improves the quality of molds. Using porous structures in any place, the Lumex Avance series enables the user to anticipate potential molding problems, such as gas burning and poor weld line formation, then address them by promoting quality improvements and reduced mold development cycles.

The machines enable air permeability to be controlled freely by creating a porous structure, simply by adjusting the density of the built part. Users can expect reductions in fill time, fill pressure, prevention of uneven filling and elimination of gas burning.

With Lumex technology, users can build inserts layer by layer, incorporating many micro-pores through which gas can escape, without adversely affecting the quality of the tooling surface. The inserts are 3D laser sintered in steel or other metals, to match the exact requirements of each injection mold tool. The dimensions and characteristics of the gas escape channels are optimized to reduce cycle times and boost productivity, while maintaining high levels of part quality, even for extremely complex designs.

These porous inserts can be manufactured into any 3D shape, facilitating reduction of lead-times, removing challenges produced by gas traps, and maintaining part quality and productivity.
