»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.
In this process nitrogen is diffused into the boundary layer of the material, which changes its chemical composition. The nitride layer created is exceptionally hard and corrosion resistant. By using high-quality steel, a hardness of up to 700HV10 and a hardness depth of 0.6mm is achieved.
Facts & Advantages:
The matching frame for any insert.
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.
POWER »Replace™« was developed for the production of small series products. The frame and insert in the mold bottom are joined by a retainer lock.
Unlike the other design options of this technology, POWER »Moduline 3™« has a stable one-piece frame, which is bolted onto the insert vertically.
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.
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.
Our best-practice molds excel in innovative technology, dimensionally accurate milling and first-grade quality. We have the worldwide highest standard hardness quality for concrete block molds which gives our products a particularly long service life.
