Injection Moulding

Cooling time can account for up to 70 percent of injection moulding cycle times. Traditional methods of creating heating/cooling channels in moulds involve straight-line drilling, which is limited in its ability to develop channels that reach critical hot spots. DMLS enables built-in, conformal cooling channels that can be optimized to draw off heat more rapidly and more evenly, dramatically reducing cycle time and increasing part quality by eliminating warpage and other defects.

 

Examples

  • 20 percent increase in mould productivity and a 50-hour toolmaking time for a blow-mold (Es-Tec)
  • Reduced cycle times from 15 to 9 seconds, enabling a 75 percent increase in productivity on a 4-bottle blow mold with DMLS inserts (SIG Blowtec)
  • Reduced cycle time by two-thirds using a DMLS designed core effectively cooling down a critical hot spot (LaserBearbeitungsCenter)
