(SJ-50B/FM600 SJ-55B/FM800 SJ-60B/FM1000)
Characteristic:
Its extruder, cylinder and screw rods are made of high quality of alloy steel that have been nitrized and processed in a precision way.
Hence it is sound in hardness, durable in corrosion resistance.
The specially-designed screw is of sound quality in plasticizing, which helps increase the production capacity.
It is applied to blow the plastic films like low density polytene (LDPE), high density polytene (HDPE) and linear low density polytene (LLDPE),
It is widely applied to producing the packing bags for foodstuff, clothing, rubbish.

Normalized steel bar is produced by normalizing which is one kind of heat treatment to get even microstructure and better mechanical properties and hardness. Our advantages and more services of normalized steel bar includes:
1) Wide range of diameters from 10mm to 100mm
2) Customized Length from 100mm to 12000mm
3) Good surface roughness: 0.4um to 1.5um
4) Good straightness: 0.5mm/m to 2mm/m
5) Good roundness: 80% of diameter tolerance
6) Diameter tolerance: -0.02mm to -0.06mm/h9, h10, h11
7) Matched further processing: Grinding, polishing, straightening
8) Anti-rusty package
9) Full sets of testing equipment: Surface, Dimenstion. Mechanical properties testing
10) Fast delivery time
