There are more than 160 professional engineers and operator here in Ronten.All moulds&dies are designed by senior engineers to ensure their precision,durability and stability.

Progressive die:For progressive die

The tolerance of spare parts is within 0.004mm,while 0.004mm to 0.006mm for feeding length.The surface roughness is from Ra0.04 to Ra0.1
Stamping speed reaches 300 to 450 strokes per minute.
Regrinding life is within 1.2 million to 3 million strokes,while total life from 120 million to 250 million strokes.

Rotor die casting:For die casting mold.we specialize in rotor aluminum die casting used in home appliance,and large wertical casting as well.Take compressor rotor die casting for example,we can totally realize no turning for top circle and inner hole of roror,The rotor cylindrical runout after aluminum casting fall within 0.04mm,while±0.01mm for deformation of shaft hloe.We can also reach no cylindrical or inner hole turning for rotors of air compressor
Three methods are available to adjust strip thickness difference,that is,disk spring type,outside cylinder type,inside cylinder type.

Compound die:For compound die.we have successfully developed our product capabilities in terms of rotor&stator compound die in different sizes,rotor&stator compound die featured forming by single stroke,compound die for magnetic and segment laminations,carbide compound die featured one slot for each stroke.
