Solidline 1™

Solidline 1™

Solid technology - for perfect results.

KOBRA developed the POWER »Solidline 1™« for products such as slope stabilization blocks.

Solidline 1™

The frame elements are arranged around the insert in the bottom mold as a classic welded assembly. The mold insert is completely welded and nitrate hardened. The FORM »Optimill nitroTM« completely levels out welding stresses in the insert and increases the mold’s dynamic loading resilience.

Facts & advantages:

  • Maximum mold accuracy due to internal KOBRA quality standard
  • Suitable for all product heights above 140 mm
  • Homogeneous hardness depth 0.6 mm
  • Hardness quality up to 700 HV10, hardness depth up to 0.6 mm

The matching frame for any insert.

Molds with Solidline 1™.

Years ago, KOBRA was the first mold maker in the industry to revolutionize the manufacturing of concrete block molds by implementing its proprietary milling technology. We have set a new level of quality with our products.

Our experienced staff use state-of-the-art technology in a customer-oriented way to develop and manufacture your reliable tool for first-grade concrete products – for any paver or block and for any block making machine, 100% reproducible.



Hollow blocks and foundation blocks combine high stability and solidity with low weight. Fixed joints are produced, which satisfy high structural standards.

Particular projects require individual solutions. Do you need curbs with vertical and horizontal displacement protection, large format systems with false joints or contours in the underside of the block?

Wall and soil retention blocks can be used for multifunctional purposes and are of central importance both in private and public spaces as design and functional elements.

For perfect results

Best in precision

With the KOBRA hardness standards, extremely high hardness can be achieved and thus particularly robust and wear-resistant concrete block molds can be produced. Different hardening processes are used, depending on the mold technology, helping to achieve smooth production processes.

Further development of the in-house carbo hardening technology enables the surface hardness to be increased to 68 HRC.

All hardness standards labeled Optimill have milled cavity walls in the mold insert, which ensure perfect angularity in the cavity. The tolerances are smaller than +/- 0.3mm. The more exact and smooth the cavity, the more exact the block!

»Optimill nitroTM« MOLD describes the nitriding process that can be used primarily for mold inserts that are high, welded and are particularly susceptible to warping.

For specific requirements

Best in pracitcal details

The stone´s product quality can be increased by the installation of KOBRA FEATURES into the concrete block mold. Each product has its individual and special demands on the mold. In order to meet these requirements, we have developed useful features, which optimally support your production processes.

With the »Hotshoe™« FEATURE, which consists of heatable tamper shoes and an integrated temperature control device, verifiably higher surface qualities can be achieved on the concrete block.

The »Multigroove™« FEATURE describes holding grooves in the insert walls, which hold the block while the mold lifts up from the production board.

The single piece »Singlebolt™« plunger is the logical continuation of the KOBRA modular system.
