(Rated for one million or more cycles) Mold design required.
- Mold base should be a minimum hardness of 280 BHN.Molding surfaces (cavities and cores) must be hardened to a minimum of 48 RC
- All other details such as slides heel blocks gibs wedge blocks etc. should also be of hardened tool steels.
- Ejection should be guided. Slides must have wear plates. Temperature control provisions to be in cavities cores and slides wherever possible.
- Over the life of the mold corrosion in the cooling channels decreases cooling efficiency thus degrading part quality and increasing cycle time.
- It is therefore recommended that plates or inserts containing cooling channels be of a corrosive resistant material or treated to prevent corrosion. Parting line locks are required on all molds.
