could be the component which should really be extremely important for the plastic molding equipments. The doing work situations in the screw barrel are often high temperature, particular corrosion, strong wear and higher torque get the job done. Thus, the expert from the experienced injection screw barrel producer, which internet site is www.screwbarrel.cn , has said the effectiveness of the screw have to be in line with the below components.
A. High temperature resistance and non-deforming
B. Excellent capability of wear-resistant and lengthy service lifestyle
C. High corrosion resistance because the materials has corrosion potential
D. High power to stand up to high torque and substantial pace
E. Small deformation right after heat process
From the above needs, individuals must have answer about which types of resources may very well be applied for making the injection screw barrel
? It needs to be the products which have high resistance to these evil situations. Now, the professional producer screwbarrel.cn for screw barrel would consider their working as example to tell persons which sorts of materials they could apply to producer screw barrel.
The No.1 materials should really be the No.45 steel that is low cost and has very good processing overall performance. Possibly the low-priced expense of this steel has let it's bad dress in and tear along with the skill for corrosion resistance. This ought to be mostly used in making the lower finish merchandise.
The No.two materials really should be the 40Cr steel which effectiveness is improved than No.45 steel but the 40Cr should be coated by using a layer of chromium to boost the capacity of its resistance to corrosion and dress in and tear. Having said that, the necessity to the chromium layer is quite higher. It will be easy-to-wear of your coating is also thin. On the other hand, as well thick coating could be easy to be peeled. The rate of this materials is comparatively higher, to not mention the finished merchandise which had utilized this kind of components.
The comprehensive overall performance in the nitrided steel and 38CrMoAl is incredibly great as well as the application of this materials to the conical twin screw barrel from screwbarrel.cn can be extensively. Normally, the thickness of the nitride layer really should be 0.four to 0.6 mm. However the capability of hydrogen chloride corrosion resistance of this materials is incredibly lower along with the price is greater than other individuals.
The final form of material which might be utilized for manufacturing the screw barrel must be the substantial temperature alloys which have better functionality than other resources. This materials doesn't need the coating material, which may very well be primarily utilized for the exclusive plastic injection molding machine. The oxidation resistant and corrosion resistance with the screw barrel with this particular materials is very large. This is the ideal materials for screw barrel creating. The majority of goods from screwbarrel.cn are manufactured of this materials.
Screwbarrel.cn is the professional China manufacturer for all varieties of screw barrel. Their branded products conical twin Parallel Twin Screw Barrel
has previously been sold to in excess of forty countries.
