Cheese moulds: how to maximize their lifespan and prevent premature wear? 

In an industrial cheese plant, moulds and block-moulds are the heart of production. Yet these essential tools sometimes wear out faster than expected. Early replacement, financial losses, line stoppages… how can you break this vicious circle? 

At Servi Doryl, a world expert in the design of cheese moulds, we know that the lifespan of your equipment is a key factor in your profitability. Depending on the type of mould, its theoretical lifespan can range from 5 to 30 years. Reaching this maximum longevity is no accident: it’s a process. From co-design to recycling, discover the 5 levers to protect your equipment fleet and optimize your production lines. 

1. Co-design: anticipating impacts on the production line 

The life of a mould on an automated line is an obstacle course: conveyors, stackers, turners. If the equipment isn’t designed for its environment, mechanical impacts speed up wear, whether for soft cheese moulds or pressed cheese moulds (with and without lid). 

Co-design makes it possible to integrate these constraints from the very start. By adjusting the plastic’s thickness, reinforcements or geometry, we avoid unpleasant surprises on moulding and pressing lines, ensuring an investment that can last for decades. 

Expert view – Fabien Thomas, Technical Sales Representative at Servi Doryl: 

“Customers often think a mould gets damaged because of the plastic material. In reality, 80% of premature wear comes from friction points on the line. By co-designing the product with the customer and analyzing their line layouts, we modify the design so that impact zones are avoided. That’s built-in durability.” 

2. Prototype follow-up: validating performance in real conditions

Nothing replaces real-world conditions. Before launching production of a complete fleet of several thousand parts, the prototyping stage is crucial. 

Rigorous prototype follow-up means testing a pre-series directly on your production line. This makes it possible to validate, visually and technically, that: 

• The block-mould moves correctly along the conveyors without derailing. 

• The line sensors detect each piece of equipment perfectly. 

• The pressing and turning stages take place without abnormal mechanical stress.

3. Mould fleet audit: stop the damage before you have to part with it 

Waiting for equipment to break before replacing it is the most expensive strategy. To avoid it, a fleet audit is your best ally. This audit is a rigorous technical analysis of your equipment at a given point in time. Our experts assess the level of wear, the geometry of the perforations and any deformation of the structures. The goal? Take the necessary corrective measures immediately to extend the life of the fleet that is still in good condition and plan investments, rather than having to suddenly part with your equipment. 

Customer testimonial – Jean-Marc, Production Director at a large dairy factory in Normandy: 

“We kept noticing micro-cracks. Servi Doryl came to carry out a full audit of our fleet. They identified a poorly calibrated pressing cylinder that was crushing our equipment too hard. Thanks to this audit, we corrected the problem immediately: we saved 70% of our fleet, which would have ended up in the dumpster six months later.” 

4. Repair service: a second life for all your dairy equipment 

A cracked mould or a block with a broken corner isn’t necessarily lost. As part of an Economy of Functionality and Cooperation (EFC) approach, repair should be the first reflex to extend the lifespan of your investments. 

Did you know that our expertise goes far beyond the standard block-mould? Our high-precision plastic welding repair service covers a wide range of equipment, which can be repaired directly in our workshops or on-site at our cheesemaking customers’ facilities: 

• Coagulation vats (e.g. polishing, scraping) 
• Mould extensions (deburring, drilling to improve drainage, straightening) 
• Moulding trays and draining trays (straightening, deburring) 
• Soft cheese moulds (deburring, drilling to improve drainage, straightening) 
• Multi-cavity block-mould structures 

This refurbishment means equipment can quickly return to the production cycle, at a cost far below that of buying new. 

5. Recycling service: a circular and responsible approach

When equipment has definitively reached the end of its life and no repair is possible, it shouldn’t become ordinary plastic waste. 

Through our recycling service, Servi Doryl collects your old moulds and accessories. They are dismantled, ground and recovered. This approach is fully in line with the ecological transition of cheese plants, turning a waste treatment cost into a virtuous circular economy initiative.
