Cultivated our manufacturing skill of high-precision shaft by manufacturing "ejector pin".
- Our ejector pin and core pin are used at a severe high temperature area as a mainly die casting pin for dies to take product out from dies.
- Made up nitrided layer more deeply than other company's by our original condition's processing and nitriding. As a result, our products have been keeping high quality, have a great strength, high-precision and wear resistance.
- Our standard "D-pin" and "G-pin" are manufactured by DAC from Hitachi Metal's special high rank of steel. Please also leave us about polish processing and cutting dice of steel.
Possible to manufacture your order by integrated manufacture, from supply materials to complete.
- straight pin 5∼30, limit L1400
- pin with a step
- sleeve pin
- plate pin
Deeply nitrided layer
Make up nitrided layer more deeply than other company's product by treatment in our nitrogenation oven. The outermost surface is over 900HV, make up nitrided layer with over 800HV of hardness at even depth of 0.05mm from surface, that has a high wear resistance and increase the strength
We are realized a guarantee of quality which can be trusted by several exclusive inspectors. They measure all of products using several measuring instruments.
TRIBEC, made in Hitachi tool
Make up specially film for each uses by "TRIBEC, made in Hitachi Tool Engineering" which full use of compound PVD skill, combination different films and searching wear resistance, lubricity, heat resisting property.
High-Precision, High-Surface Roughness
It's effective in improving adhesion of a surface treatment, prevent a slip and burning by finishing with high-surface roughness of R-part (curving surface) and the tip of form processing point. Also we have been trying as hard as possible to finish without cutting.
