1-Die 2-Blow Cold Heading Machines are suitable for wire diameters from Ø0.5mm to Ø5.5mm.

With wire diameters less than Ø4.5 mm, material transmission method without clamp over-die is used.

For wire diameter Ø5.5mm we offer 2 different material transfer methods according to product length specifications, and there are fixture over-die and no-clamp over-die.

What is a non-clamp over-die?

Round shear break => material ejection => 1 blow transfer to 1 die

2-Die 3-Blow Micro Cold Forming Machines RG-1315L / RG-1310F


The RG-1305 Micro cold forming machine is suitable for very precise and short workpieces. The material transfer mode is designed without clamping over the die, through materials with two punches to transfer materials from the first die to the second die after the completion of the three-die production. The ideal vacuum feeding device instantly transfers the finished product to the collection box, which can prevent splashing, smearing, lack of product, material leakage and mixing problems.

Offered 2 different material transmission methods for different choices according to the different length specifications of the product. RG-1310F has fixture over-die and RG-1310 has no-clamp over-die.

The separated die holder can adjust the concentricity independently. The material-receiving function can prevent material collision and the 2 blow/3 blow can set monitoring accuracy independent.
