Original diamond, the hardest of all materials, reduces the processing time. You can work either with two graduated roughnesses (rough and fine) or only with a middle roughness.

Easy

1. You can produce a clean and precise surface with less grinding and with less pressure.
2. By the diamond covered abrasive surface of the whole diameter and of the front area, we can ensure a high precision in the rotation and form of the sealing and mating area.
3. There is no need to take care of a special rotation direction as there is no wear of the cutting edges.
4. With the delivered centering ring, we can ensure an exact alignment of the gooseneck and nozzle tip to the centering of the clamping plate.
5. The sealing and mating areas can also be reworked in hot condition.

Durability:

The strong one-cristal-diamond is very resistant. It grinds all strong materials like steel, glass, ceramics, wolfram karbid, stone etc. Because of this extraordinary resistance in wear we can ensure that the hard zinc cinder and other residues can be ground out easily and without abrasion. The temperature resistance of up to 500° additionaly reduces additionally. You can clean the grinding area with the ultrasonic-toolcleaning- machine (FISA) or with one of the according acids.

The position of the freezing point doesn‘t have to be exactly defined. Increase of the flow velocity.

Disadvantage:

A very high pressure peak is located in the nozzle body area, high loss of the specific injection pressure.

General:

The nozzle tips, as well as the nozzle body are designed according to flow technological aspects. The mass of the nozzle tips is distributed in a way, the direct thermal radiation will avoid a freezing of the zinc in the tip of the nozzle.

• Material: forged hot working steel 1.2343/44
• Heat treatment: through hardened under vacuum
• Processing: we grind the sealing surface of the cone

We provide nozzle tips with and without threads We can produce nozzle tips according to customers requests, if a larger quantity is ordered.

Less pressure peaks due to the smoother transition.

Disadvantage:

Pressure peaks are located in the nozzle body area.

Higher heat capacity due to higher volume, less flow resistance, wear-out due to pressure peaks is relocated into the nozzle tip, The lifetime of the nozzle body is increased.

Disadvantage:

The freezing point has to be exactly defined.
