ACCURA LASERFORM ST-200

Accura Laserform ST-200 material is a specialy stainless steel composite developed for use with SLS systems to produce durable, fully dense metal parts and tooling inserts for injection molding and die casting applications.

Typical Applications:

  • High-temperature applications

  • Metal tooling inserts

  • Short runs of metal parts and prototypes

  • Complex geometries and features

Benefits

  • Parts and inserts from CAD data-no tooling

  • More productivity from existing skilled labor

  • Durability

  • Charateristics similar to P20 steel

  • Eliminates tool making or casting

  • Fully dense, annealed inserts and parts

  • Heat resistance

  • "Tool-less" manufacturing

this is text meant just to take up lots of space at the bottom of the page, so that if there is only a table or something in the content part of this page, the content still takes up the majority of the screen. if there is not any text here, then sometimes there will be just a table here, and the left navigation bar to the left will be kinda wide...
