Principal Layout of the STRECON^® Stripwound Container

The STRECON stripwound container consists of three integrated tool elements but shall be regarded as one solid body. The inner ring of the container is the winding core on which the strip material is wound. The main section of the stripwound container is the coiled strip material. Outside the coiled strip is mounted an outer casing for tool handling, assembly, and fixation in the press.

In addition to the container itself, the pre-stressing tool also includes a wear ring that can be defined as a safety ring to the STRECON container.

STRECON has developed a few standard tool system sizes for HPE purposes but can also if requested make customized tool designs.

Materials applied

Winding core: High-alloyed tool steel material from Uddeholm hardened to 56 HRc. In very special HPE container designs we use a winding core of tungsten carbide.

Steel strip material: A very strong and exclusively developed steel strip material is used. The strip material is fully elastic up to 2000 MPa. Hardness equal to 64 HRc.

Outer casing: A standard and low hardened tool steel material is used (44 HRc).

Wear ring: This intermediate ring is considered an integrated element of the STRECON stripwound container. The ring is made of high-alloyed tool steel materials from Uddeholm, mostly hardened to HRc 54.

The exact tool steel materials will be fixed during tool engineering and maintained on tool drawings.
