Advantages of stamp punch insert

High hardness, high wear resistance

Long service life, corrosion resistance, no rust

High hardness, high wear resistance, high compressive strength

Powdered high-speed steel, excellent wear resistance and toughness.

ZK can provide the different coating for the inserts according to customer’s requirements.

1. TD Coating Centre (TDCC) is synonymous with the supply of high precision, high performance tooling and machine parts that improve productivity, reduce downtime and maximise part life. ZK do this by the correct combination of metallurgy, correct selection of base metal, appropriate heat treatment and surface engineering, and then, by high quality manufacturing of the part.  

The range of coatings and surface treatments we are involved in are the Thermal Diffusion (TD) coating, which has proven to outperform many competing coatings, various PVD coatings incl DLC, and surface treatments such as controlled nitriding, boriding, etc.  

The manufactured tooling and parts – coated or uncoated – are precision-ground (not only machined) from various steels, tool steels, specialized PM tool steels, carbides or tungsten alloys. ZK look at the overall design of the part including correct tolerancing to ensure a first time fit and to maximize part life. ZK have more than years of experience in this field. It’s all about getting the highest performance out of the parts. ZK are a one-stop solution for ultimate performance! 

ZK also have out own range of standard parts such as piercing punches that provide improved life and require less re-sharpening. Find our more about our exclusive range of piercing and ball lock punches, dies, pilot pins, locating pins etc. here.  

2.Physical Vapour Deposition or PVD coatings have made their mark on the manufacturing industry mainly though the cutting tool market. Although this market still remains the biggest application for these coatings, their excellent properties of hardness, low friction and excellent wear resistance can be taken advantage of in many other tooling and component related applications.

ZK can offer the follow standard type PVD coatings:

Titanium Nitride (TiN)

Titanium Carbo-Nitride (TiCN)

Titanium Aluminium Nitride (TiAlN) 

Titanium Aluminium Carbo-Nitride (TiAlCN) “aka Variantic”

Chromium Nitride (CrN) 

Aluminium Chromium Nitride (AlCrN – a.k.a. AlCRONA).

Chromium Carbide topcoats (CrC))

Diamond Like Carbon (DLC) – super low friction,  high hardness coating is available

YDLC – Multi-layered DLC coating for improved adhesion

The above can also be supplied in duplex format for applications requiring higher surface loading and improved fatigue life.

ZK through measure the parts to determine that the parts meet the tolerance range required, and then deliver them to customers by sea/land/air and other means of transportation according to the different packaging methods required by different customers.
