The benchmark for precision in concrete formwork construction
When it comes to molds for concrete paving stones, slabs, and masonry blocks, RAMPF PRIME-TEC sets the standard. Made from solid tool steel, precisely hardened, and coordinated down to the last detail, the mold stands for dimensional accuracy, durability, and efficiency.
PRIME-TEC is our best-selling paving stone mold—a classic that keeps reinventing itself. Whether standard paving stones, large-format slabs, or special geometries, this mold delivers precise results—cycle after cycle, stone after stone.
PRIME-TEC, your mold for paving stones and other concrete products, stands for:
- Consistent top quality in production
- High dimensional accuracy thanks to precise fits
- Long service life thanks to high surface hardness and low wear
- High dimensional stability with optimal vibration behavior
PRIME-TEC: Every tenth counts. Every shape fits.
Wear resistance thanks to CSI Diamond
PRIME-TEC is manufactured in-house and hardened with CSI Diamond. This surface treatment achieves a hardness of up to 68 HRC and specifically counteracts wear. The result: minimal wear, longer service life, and consistently high dimensional accuracy—even under extreme loads.
Operational safety and experience
For decades, RAMPF has been developing and optimizing steel molds that perform reliably in continuous use. With PRIME-TEC, the mold insert is manufactured from a solid block, precisely milled, and screwed together if necessary. This compact design ensures maximum dimensional stability, even vibration distribution, and precise results in your production—cycle after cycle.
Manufacturing according to RAMPF standard
We work according to our in-house Rampf standard—with significantly tighter tolerances than in the SLG standard. This means maximum fitting accuracy, reproducible quality, and process reliability on machines from a wide range of manufacturers.
Reusable component
Many mold parts of the PRIME-TEC and PRIME TEC S, such as frames (in bolted construction) and punches, can be reused multiple times at the customer's request. This reduces downtime, simplifies maintenance, and lowers operating costs in the long term.
Designed in steel. Made for concrete.
Depending on the stone format, geometry, and machine, suitable designs are available for the mold:
- Frame insert bolted – classic, stable construction; frame is reusable
- Frame insert welded – for maximum stability and durability
With this selection, Rampf offers maximum flexibility – from standard paving stones to individual stone formats.
More than standard – shapes with a system
System components and upgrades are available depending on production requirements:
- Centering – longer service life thanks to optimal pre-centering
- FlexWay® – pneumatic centering & machine-friendly sliding system; shortens cycle times and minimizes wear on the chamfers of the pressing pieces
- Filling compensation for large-format bricks – uniform density, homogeneous brick structure
- Heating – less adhesion to the pressure pieces, better surfaces
- Vibration insert – decoupling between mold frame and mold insert for better filling and compaction results
- Vibration metals – optimize vibration behavior and compaction for large-format blocks; recommended from approx. 400 × 400 mm
Our sales team will help you select the optimal equipment for your production – tailored to your machines, product geometries, and production volumes.
Application technologies – perfectly tailored to your production
PRIME-TEC delivers impressive results in all common manufacturing and application technologies. It can be precisely adjusted to systems with mold attachment strips and always maintains dimensional accuracy and dimensional stability.
Even in demanding processes with height limits, multi-stage loading, or oscillators, PRIME-TEC delivers accurate results, clean edges, and consistent quality throughout the entire production cycle.
Compatible with board pavers, multi-layer pavers, or special systems, PRIME-TEC integrates seamlessly into existing lines. Whether classic paving stones, structured stones, or special formats: PRIME-TEC is the right mold—precise, durable, efficient.
