Our steel punch pin has tough and resilient shaft; its hardness has been greatly improved by our nitrogen treatment. Moreover, we are pleased to manufacture punch pins with other dimensions, lengths and materials according to your requirements.

More press die components can be produced according to DANLY / DME / HASCO / TOHATSU / FIBRO / AGATHON / STRACK / PEDROTTI / RAYMOND / FUTABA / SANKYO / PROGRESSIVE / RABOURDIN, etc.

Application
As also a professional hole punch manufacturer, we adopt the imported high quality steel, the newest CNC machining center and Swiss Archie's cutting mill machine line to the manufacturing and processing of our roll pin punch.

We are happy to customize your designs and logos. Our punch pin is suitable for different plastic bag making machines; it can punch such materials with 0.01mm single-layer as the plastic bag, paper, non-woven fabrics, PE, OPP, PO, PP, PVC, PPE, PPU, OPE Film, etc. Also, the punch pin can be easily replaced if it is worn.

Surface Coating
TiN (Titanium Nitride) PVD (Physical vapor deposition) Coating
TiN is the most economical and commonly used PVD wear resistant coating and it has the following advantages:
a. Excellent wear resistance
b. Superb performance of lubrication
c. Thermal stability suitable for most cold work metalworking applications
d. High micro hardness up to 2,300 Vickers
Note: TiN is recommended to be used with lubricants; and it is not applicable to stainless steel, nickel or copper applications.

TiCN (Titanium Carbon Nitride) PVD Coating
TiCN can be widely applied to PVD coating on stainless steel, nickel and copper metals; and it has the following merits:
a. Higher hardness and lower coefficient of friction than that of TiN coating; thus, it has extremely high wear resistance
b. Improved performance of lubrication
c. Extremely high micro hardness up to 3,000 Vickers
Note: It is suitable for stainless steel, nickel or copper applications.

TiAIN (Titanium Aluminum Nitride) PVD Coating
Particularly suitable for application generating heat on surface, TiAN can convert the aluminum constituent to aluminum oxide, which provides an extra protection against shear stress and wear resistance on cutting edges. TiAN has the following features:
a. High thermal stability
b. Extremely high micro hardness up to 3400 Vickers
