Moulds for block making machines
ALFI Technologies designs and manufactures block making machine moulds under the ADLER brand. Our teams design, build and maintain these moulds at our two workshops in France, in Crèvecœur-le-Grand and Marigny-Saint-Marcel.
Technology and precision for moulds that last
Blocks, floor blocks, pavers, kerbs: moulds that hold their dimensions, so your products keep their weight. The right measure is not the price of the mould, it is the cost per block sold.

Machine and mould work as one system
The mould transmits the machine's vibration to the concrete. Vibration does the filling, the compaction and the demoulding. We design both, and we set them up together at your plant.
Designed for your machine
Vibration technology, pallet size and material (wood, plastic, steel), aggregates: the mould is designed for the machine that will run it.
All block machine brands
ADLER machines and machines from other manufacturers, single or double moulds.
Machine and mould set-up with InView
High-speed camera at 1,000 frames per second: vibrations and movements analysed, settings optimised on site.
The right steel for each part, where the mould wears
Exploded view of a welded mould.
A block machine mould works under vibration, compression and abrasion at the same time. Each part gets the steel and treatment that match its load, so the mould holds its dimensions and your products their weight.
The load-bearing structure uses high-yield-strength steel. Wear surfaces are hardened to 65 HRC to a depth of 2 mm. Precision parts are machined to a fit of 0.1 mm. Dimensions are guaranteed to within 0.5 mm across the complete mould. Each mould is delivered with its quality certificate and a handling and maintenance manual.

The mould logbook and its quality certificate
Every mould ships with its logbook and quality certificate. The 12 checkpoints are validated by our workshop, then ticked by you on receipt: the signed certificate serves as the acceptance report.
- Geometry and dimensions checkedTamper head, mould box and cavity/core assembly, checked one by one by the quality department.
- Steels, treatments and finishesSteel grades and heat treatments, painting of the mould box and tamper head.
- Fixings and testsTamper head and mould box fixing, tamper head/mould box function tests before shipment.
- Handling instructionsLifting points, slinging, transport and storage of the mould and tamper head.
- Baseline measurementsDimensions recorded at delivery are then used to track wear and order spare parts.
Maintenance and cleaning: the mould stand
A clean mould holds its dimensions. The stand turns the mould box over and stops it in the required position for safe inspection, cleaning and maintenance.
- Full motorised rotationHalf-turn in 15 seconds in both directions, indexed and locked rotation.
- Quick mould box fixingFour quick-release clamps and a safety lock, cradle suited to single or double moulds.
- MobileCan be moved by forklift, floor fixing possible.
- OptionsGantry and tamper head cleaning kit, galvanised version built to last.
On site, with your teams
Installing the first mould
On every type of machine, with a check of the machine settings.
On-site training
Fitting, removal and set-up to hold product weight.
Mould weight and cycle rate
How mould weight affects the cycle rate of your machines, explained and set up.
Workshop support
Our two workshops in France and our Casablanca service centre handle repairs and provide on-site support.
When the mould wears, the block grows, and the margin goes into the concrete
Dimensions open up: every product carries more concrete, sold at the same price. Measured weight, not breakage, should trigger re-adjustment, repair or mould replacement.
Under controlDimensions held, nominal weight, settings monitored.
Watch zoneThe mould wears, the weight drifts: the weighing tool alerts at the +1 kg threshold.
LossConcrete given away with every product = lost margin.
The right measure is not the price of the mould, it is the cost per block sold.
A mould that holds its dimensions makes a block that holds its weight. The rest comes down to set-up: vibration, filling, tamper head. As the manufacturer of ADLER machines, we set up the machine and the mould together and support your teams over the long term.

Calculate my cost per block with an expertYour products weighed, your moulds' condition tracked
A tool connected to the machine that turns weight into decisions. Indicators are displayed live on a tablet, next to the machine.
MEASURE
Weighing at the machine outlet
Products are weighed row by row, continuously.
ALERT
Drift detected early
Alert when the threshold is crossed, before the drift becomes costly.
DECIDE
Act on weight
Adjust, repair or replace the mould at the right time, not when it breaks.

FAQ
It depends on the type of mould and the workshop's workload. It is stated in the offer and confirmed with the order, once your approved drawings are received.
Yes. Give us the brand, the model, and the pallet size and material: the mould is designed for the machine that will run it.
With the weighing tool at the machine outlet: your products are weighed continuously and an alert is triggered as soon as the weight drifts beyond the set threshold.
We refurbish moulds and supply wear parts. Send photos and the mould reference for a quote.
Yes, to more than 50 countries. EXW, CFR or DAP offers as you prefer; in Morocco, our subsidiary provides repairs and support.
