What is Bimetallic Parallel Twin Barrels for Extrusion?
Bimetallic parallel twin barrels are made of two alloy metals. The first metal is base material and the second metal is the coating material. So the bimetallic parallel twin barrel has better corrosion and abrasion resistance,more durable, last longer than non-bimetallic ones.
How to make the bimetallic parallel twin barrel with two metals?
Barrelize use the advanced gas furnace to centrifugally cast the lining alloy on the inner surface of the barrel, which greatly provide high surfacing bonding strength, and improve the resistance of the bimetallic parallel twin barrel.
What 's the specification of Barrelize Bimetallic parallel twin barrel?
For the first base material, you can choose 38CrMoALA and 42CrMo. For the second metal, Barrelize can offer you iron-based alloy, nickel-based alloy, tungsten carbided alloy. Barrelize can make the thickness of the bimetallic layer : 1.5-2mm. The hardness of iron-based bimetallic parallel twin barrel can reach HRC60.
The general features of using Barrelize bimetallic parallel twin barrel:
1.High performance backing
2. Bimetal construction
3. Bimetallic bore inlay
4. Inseparable inlay bond
The general advantage of Barrelize parallel twin barrel: are corrosion resistance and wear resistance,improve the strength resistance to fatigue,finally improve the usetime.
What is the application for Barrelize Bimetallic parallel twin barrel?
Additive plastic materials with less than 30% glass fiber, nylon, PC, PPA, te, fire PC+ glass fiber, Nylon + glass fiber.
