Screw Elements With Nitride Steel 38CrMoAla HV800 - 900 Depth 0.4 - 0.7mm

Screw Elements With High Quality Nitride Steel 38CrMoAla Nitride Hardness HV800-900 Nitride Hardness Depth of 0.4-0.7mm

Product  Description:

     Bloom manufacture screw elements,barrels and other extruder machines.Screw elements are the main working parts for twin screw extruder which determined the quality and output of plastic products.With high quality,the screw elements assure plastic molecular mixing,cutting,spreading as well as reacting among themselves etc.Extremely high self cleaning performance assure the high quality of the whole production line,for this,our company combiend our experience for years,the merits about foreign countries and the customer’s use,then take them into action,designed all kinds of suitable processing screw element with reasonable parameters,high self cleaning performance,wear resistance,corrosion-resistance.

    The function of screw element is mainly used to convey materials. Feeding and degassing sections generally have the long pitch to improve the material conveying and degassing. For material of low bulk density, feeding sections can use deep channel components to increase feeding capacity. The metering extruded segmented screw elements generally adopt the small pitch which is used to pressurize, improve the density of the material at the die head, and make the extrusion more stable.

Bloom manufacture screw element suitable for the following extruder products brand:

1.Made of high speed steel (W6Mo5Cr4V2 and M2),Vacuum heating treatment and overall hardening, high wear-resistance and toughness.

2.Made nitrider steel (38CrMoAIA). high hardness, super toughness, anti-corrosion and anti-burst.

3.Made of HIP material imported from Europe (super wear-resistance powder metallurgical steel X245 and WR5).With features of high wear-resistance. high torque, anti-corrosion and anti-burst, this type of screw elements is used to produce such engineering plastics as that of more than 50% fiber glass.

4.Made of Hastelloy C-276 (00Cr16Mo16W4),super anti-corrosive nickel alloy. this type of screw elements is used to produce fluoroplastics(F46).
