TOYOTANSO TTK series material is a newly developed isotropic extra fine grain graphite material in the last few years, whose grain structure is of higher homogeneity. While TTK-4 material behaves excellent in the machining property, the wearability and the roughness of discharging surface.

Applicability: suitable for the machining of spares with higher requirement as well as ultraprecise dying such as dyings of mobile and telephone, dying of precision connector and mesh dying, etc.

TOYOTANSO TTK-5 material is a type of isotropic extra fine grain graphite material. It behaves extremely excellent in the strength, the wearability and the loss resistance.It can achieve ideal effect at key positions such as the scrap chopper.

Applicability: suitable for the machining of ultraprecise dying such as IC enclosure dying, dyings of mobile and telephone and dying of precision connector, etc.
