Product category: Single screw extruders

Plastification Screws

HELIX manufactures plastification screws according to client specifications and is specialised in producing screws with a diameter of 10 to 100 mm with a length of up to 3000 mm.

In the field of plastics extrusion, there is an increasing demand for sophisticated barrier geometries and mixing and shearing parts. HELIX has the capability of manufacturing screws with very complicated barrier and mixing zones very precisely and rationally by using a software specifically developed for this purpose - including even the smallest of screw diameters.

Grooved barrels

Grooved barrels or grooved feed sections are used extensively in the plastification units of extruders and injection moulding machines. For many years, HELIX has specialised in the manufacturing of grooved barrels. With its unique technology for producing grooves, HELIX has become the universal supplier of all kinds of grooved barrels:

Axially grooved barrels - with grooves running along the axis of the barrel
Helically grooved barrels - with grooves running helically within the barrel
Grooves manufactured as:
square grooves
trapeze grooves
sickle grooves
round grooves orany special shapes according to client requirements


The standard material used for grooved barrels is nitrided steel that is nitrided with gas or plasma. In addition, HELIX also provides the possibility of manufacturing wear protected grooved barrels made of

fully-hardened tooling steel
bimetallic plated material
HIP (Hot Isostatic Pressing) material


starting with a nominal diameter of 10 mm
lengths of up to 4000 mm
grooved lengths of up to 4000 mm
weight of workpiece up to 2 t.

HELIX delivers grooved barrels complete with cooling mantles - tested and ready for installation.

Company details

HELIX GmbH is a highly specialised manufacturer of parts and components for plastification and packaging machinery. The products range from grooved barrels, cylinders and screws for extrusion machines to feeding screws and augers for dosing machines.

HELIX GmbH is a global leader in manufacturing helical and axial grooves in feeding barrels and cylinders. Leading machine manufacturers have relied on the efficiency and performance of HELIX for many years.

On the market for over 40 years
HELIX GmbH was established in 1964 under the name of Schäfer+Weinbrenner by Walter Weinbrenner and Eberhard Schäfer in Waiblingen-Hegnach, Germany. Since 1977 it is a private limited company. From the beginning, the main focus was on screws for extruders, cylinders and augers. Another area of business was the manufacturing of special purpose machines.

At the beginning of the 1990s the company founders passed the business on to their sons, Armin Weinbrenner and Klaus Schäfer. In 1993 the company concentrated on the areas of screws, cylinders, grooved barrels and augers.

In 1996 a subsidiary was established in Polkowice, Lower Silesia which today is called PROMAX sp.z o.o. This subsidiary has recently been incorporated as an extended contractor for HELIX manufacturing processes.

The main advance in development is currently made with the manufacturing of helical grooves in grooved barrels, cylinders with grooves and the corresponding complicated barrier screws. HELIX GmbH recognised this trend and in 2000 developed and built a manufacturing machine that enables HELIX to produce grooves in dimensions and to a degree of quality, that no other competitor has yet attained.

Schäfer+Weinbrenner GmbH was renamed to HELIX GmbH in 2005 after Klaus Schäfer left the company. Since then Armin Weinbrenner (a graduate engineer), is the managing director, overseeing a staff of about 30 employees.

The Locations
The parent company is located in Waiblingen-Hegnach, Germany easily reachable just east of the federal capital city of Stuttgart. Since 2000, the subsidiary PROMAX is located in a newly constructed and modern building in Polkowice, Lower Silesia. Both locations have state-of-the-art CNC lathes, CNC milling machines and a variety of metal tooling machines. A modern computer-aided production control station organises all operations between the two locations and the company own truck shuttles between Polkowice and Waiblingen.
