SCREW & BARREL
We develop and product single screws and twin-screw, their diameter ranges up to 132mm and their length to 3700mm . We only use material that imported from Germany or Japan once the geometry has been determined. The screws are produced by the following individual processes.
The blanks are prepared and annealed
Modern CNC-lathers ensure a high degree of constant quality
Well-Proven special boring systems are used for producing the cooling channels
The screw geometry is milled out by computer numerical controlled machines
Before they undergo heat treatment, the work pieces are checked for warppage. Deviations are corrected immediately
The screw flights are polished by several stages, surface roughness below Ra 0.8 g m
An acceptance report is written out of each screw during final inspection

| TYPE | Outside diameter | Length |
| Single Screw | φ30~ φ370mm | 5000mm |
| Twin Screw | φ30~ φ150mm | 5000mm |
One programmed comprises barrels of diameter up to 132mm and length of up to 4000mm , we use material that imported for Germany or Japan . We supply barrels for single-screw or twin-screw that is produced by the following individual processes.
Precise positioning of the barrel bores. The latest special boring machines are employed
Finishing the bore of barrel by CNC lathe
Highest surface quality through honing of the barrel bores
Even the most difficult shapes can be machined to accept finishes on CNC machines
Highest wear-resistance is obtained by deep Nitriding of the barred bores
Completed barrel is checked by gauging machine before delivery
An acceptance report is written out of each barrel during final inspection
