Optimill carbo 68 plus™

Optimill carbo 68 plus™

Best in precision.

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

The outermost boundary layer of the mold is enriched with a carbon-diffusing medium in a thermo-chemical process and is then quenched, i.e. hardened. After hardening, the workpiece is tempered to reduce the stresses that have formed inside it and to generate the required durability.With this additional »plus« surface hardness, KOBRA is able to extend the service life of molds decisively, depending on the production parameters in the precasting plant. All cavity walls in the mold insert are milled exactly. Smooth surfaces and precise, straight mold walls facilitate the production and demolding process.  

Facts & Advantages:

  • Highest quality standard for hardness, dimensional accuracy and wear resistance through further development of the carbo hardening process
  • Cavity tolerances less than +/- 0.3mm
  • Hardness quality 68HRC
  • Homogeneous hardness depth 1.2mm
  • Cost efficiency due to long service life

The matching frame for any insert.

Technologies with Optimill carbo 68 plus™.

All KOBRA technologies are united under the brand KOBRA POWER. The construction of the concrete block mold depends on the stone systems to be manufactured as well as the individual conditions in the plant. Therefore, for each product type exist a matching technology, which is adapted to the products processes specific demands.

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

Unlike the other design options of this technology, POWER »Moduline 3™« has a stable one-piece frame, which is bolted onto the insert vertically.

The mold bottom of a POWER »Moduline 2™«- mold is made up of only three components – the insert, the flanges and the wear plates.

POWER »Moduline 1™« comprises of an insert frame joint with tongue and groove, whose vibration behavior on the one hand helps to achieve improved compaction of the concrete, and on the other hand, due to the decoupled insert, it achieves a damping effect, which can reduce wear of the mold.

On the outsides of a POWER »Dynamic 1™« mold there are all round trapeziums, via which the vibrating insert is clamped in bolted frame elements by means of a rubber bearing.

The POWER »Boltline 3™« is used for the production of paver and slab systems from 300mm edge length.

POWER »Basicline 1™« is the classic mold for the production of medium and high paving products.

POWER »Boltline 1™« is used for all high products, such as hollow block, solid block, curb and round curb molds.

The mold bottom of the POWER »Basicline 2™« comprises a precisely machined mold insert made of block material with all-round cavities shaped to hold the flange assemblies including rails.
