Permeable paver molds

Permeable paver molds

Colorful variety

Permeable (or drainage) pavers are characterized in particular by their ability to allow rainwater to quickly infiltrate the pavement surface into the soil. The wide joint pattern compared to other paved surfaces enhances water percolation enormously

Permeable paver molds

There are no limits to the format and coloring of this block. Whether drainage paving combined with slip resistance for trafficked surfaces or individually designed grass paver systems in conjunction with gavel or planting – the design options are diverse. This also applies to the mold technology with which we implement your block systems.

Based on the KOBRA modular concept, we produce a concrete block mold perfectly suitable for your product and take into account the production requirements and type of use of the block.

The matching frame for any insert.

Best in technology

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.

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

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.

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.

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

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

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.

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.

»Flamecut carbo™« MOLD is particularly suitable for rustic briquet and tumbled paver blocks, in which service life is prioritized over perfect dimensional accuracy.

With this production method, KOBRA combines the advantages of state-of-the-art milling and hardening technology with the tried and tested options of flame-cutting technology. »Optiflame carbo 68 plus™« molds have flame-cut cavity contours and exactly milled base layout.

Improvement in the wear resistance of concrete block molds with completely flame cut and manually polished cavity walls is achieved using the »Flamecut carbo 68 plus™« hardening process which, depending on the production parameters in the precasting plant, can make a decisive contribution to extending the service life.

Optiflame describes the use of milling and tried and tested flame-cutting technology together in a mold. The cavity contours are flame cut, the base layout is precisely milled.

For specific requirements

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.

The FEATURE »Flexshoe™« is a useful compacting aid, especially for large format products and special formats. The tamper shoes are mounted on rubber supports which ensure improved compacting results and higher block surface qualities.

The »Headguide™« FEATURE ensures absolutely correct and centered installation of the overall mold in the machine and thus protects particularly sensitive mini chamfers on large-format tamper shoes.

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

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