plastic extruder kneading blocks from China

Description for kneading blocks

1 Depth of Welding layer: ≥0.8mm-2mm
2 Thickness of welding layer:integrted state HRC60-75
3 Allowable working temperture:≤950 ℃
4 Corrosion resistance:metalliZed ceramics show nice performance of corrosion resistance in various kinds of acid and alkali
5 Screw element base materials fit the thickness of screws,and an optimal state is achieved.

The technical process

Quenching & Tempering → Rough Machining → pulling internal involute spline machine → Strand-cutting → Milling machine or lathe(Semi Finishing Machining)→CNC Machining center→CNC threadgrinder(Finish machining) → vacuum quenching → Inspection

Certificates

CE/ISO/SGS/TUV to assure machine qulity.

Packaging & Shipping

Pacakge: Wooden case or Using Anti-rust oil processing, then use stretch film cover extruder against moisture damage.

Shipping: By sea or By express
