What are Conical Twin Barrels for Extrusion?
Conical Twin Barrel is the matching barrel for twin screws that have two intermeshing identical screws. They work together to convey, compact, melt, stir and press the plastic. Compared to a single barrel, the Conical twin barrel have two barrels, therefore it offers more process flexibility and has better mixing capability.
How to make the Conical Twin Barrels with nitriding treatment?
Barrelize has its own nitriding furnace in-house. The Conical twin barrels will be put into the nitriding furnace with nitrogen under a certain temperature and humidity environment. After 5 days of deep nitriding, a nitrided layer with relatively high hardness is formed on the surface of the barrel.
What 's the specification of Barrelize Nitrided Conical Twin Barrels?
The nitrided layer can reach 0.05-0.07mm. The hardness can reach HV950±50or above, equivalent to HRC68~69.
The general advantage of Barrelize Conical Twin Barrels: corrosion resistance and wear resistance,improve the strength resistance to the fatigue, and finally improve the usetime.
