A Shared Journey Since the Founding of DAC Industrial

Since DAC Industrial was founded, the management team has shared a single goal: to offer solutions 100% tailored to each client’s actual needs. This goal remains the same following the retirement of Domènec Llop Solà, who brings his career to a close by sending a farewell letter that serves as a sincere thank-you to all clients for the trust, support, and collaboration they have shown throughout the company’s history.

Robert Alvaro Takes the Helm: What Remains the Same

Robert Alvaro now assumes leadership of the project, ensuring continuity and the same high standards as always. DAC Industrial’s way of working remains unchanged: design, manufacturing, assembly, commissioning, and maintenance continue to follow the same criteria and reflect the same commitment to each client.

The same team of professionals and technicians behind every project

This change in leadership does not affect the DAC Industrial team. The people who design, manufacture, and commission each piece of equipment remain the same. It is precisely this continuity that allows us to maintain the same level of service without any interruption.

Why doesn’t equipment “that works for any plant” work for yours?

Every production line has its own throughput, its own product, and its own spatial layout. Standard equipment is designed for a broad range of conditions, not for your specific ones. When it fits, it’s only an approximation: it meets the minimum requirements, not the optimal ones. That means operating below the line’s actual capacity or oversizing a section that didn’t need it. In both cases, the rest of the process pays the price for the mismatch.

The three most common mistakes when the machine isn’t designed for your process

• Incorrectly sized capacity. Equipment calculated based on a generic industry average, not on the plant’s actual throughput, particle size distribution, or production peaks. The symptom isn’t always a breakdown: often, it’s a production ceiling that can never quite be explained.
• Incompatibility with the existing line. Differences in height, connections, or speed compared to the rest of the installed equipment. Every subsequent adjustment—a different flange, an added support—means time and cost that weren’t in the initial budget.
• Complicated spare parts and maintenance. If the manufacturer of the standard equipment isn’t familiar with the rest of the line, maintenance becomes a matter of managing multiple suppliers at once. And when there’s a shutdown, every hour spent trying to figure out who’s responsible is an hour of lost production.

What really sets a custom manufacturer apart

Many suppliers in the industry boast about manufacturing “custom” machinery, but very few of us control the entire process (design, manufacturing, assembly, commissioning, and maintenance). When the same team that designed the machine is the one that maintains it, there’s no loss of understanding between “how it was designed” and “how it’s repaired.”

At DAC Industrial, we handle this entire process with our own workshop and technical team, working on a range of conveying, mixing, and dosing equipment designed for bulk solids processes. It’s the same principle we’ve already explained in detail regarding how we approach each custom project, applied here to the specific problem of equipment that doesn’t fit the production line.

How to Know If Your Line Needs a Customized Overhaul

First and foremost, answer these four questions to help you pinpoint the problem before making a decision:

• Is the production line consistently operating below its theoretical capacity?
• Have adjustments or modifications to the current equipment become routine?
• Is it difficult to find replacement parts or suppliers who are familiar with the installed equipment?
• Does an unplanned shutdown affect more than one stage of the process?

If you answered “yes” to two or more of these questions, the problem isn’t just one of maintenance—it’s one of design. Our specialized technical consulting service begins precisely with this diagnosis. And if the decision you’re facing is broader in scope (whether to continue using the current equipment or replace it), it’s also worth reviewing the criteria for selecting the right machinery.

Frequently Asked Questions

How long does it take to design custom equipment compared to standard equipment? 

The timeframe depends on the complexity of the process; the starting point is different in each case: we don’t simply choose from a catalog—we size the equipment for the plant’s actual flow rate and available space. That initial analysis pays off later in fewer adjustments. 

Is custom equipment more expensive to maintain? 

Not necessarily. Maintenance costs depend on the availability of replacement parts and the manufacturer’s technical knowledge of the installed equipment, not on whether the design is off-the-shelf or custom. Since we manufacture our own equipment at DAC Industrial, we guarantee full availability of parts and replacement components.

Can I integrate custom-designed equipment into a production line already set up with equipment from other manufacturers? 

Yes, this is common. The custom design is based precisely on the conditions of the existing line, including equipment from other suppliers with which it must coexist.

What information does the manufacturer need to size the equipment correctly? 

Flow rate and type of product to be handled, available space, equipment it must connect to, and plant conditions (temperature, dust, humidity). The more accurate the information, the less room for error. That’s why at DAC Industrial, before we start working in the workshop, we invest time in understanding every last detail of our customers’ needs.

Does your production line exhibit any of these issues? Request a no-obligation technical assessment

At DAC Industrial, we work every day with managers, engineers, and plant supervisors who ask themselves the same question: Should we upgrade now, or hold out for one more cycle? This article is not intended to be a sales pitch. 

It aims to help you determine, based on technical criteria, whether the time has come to take action.

Why is the decision to replace machinery never simple? 

The cost of a new machine is a specific figure, easy to put on the table during a management meeting. The cost of continuing to use obsolete equipment, on the other hand, is diffuse: it’s spread out over maintenance hours, production losses, order delays, and small inefficiencies that, when added up, weigh much more heavily than they appear at first glance. 

This asymmetry is why many industrial companies delay replacement longer than they should. It’s not a lack of foresight; it’s that the cost of inaction doesn’t appear on any invoice—it appears on the income statement, diluted across many different line items. 

That’s why, before looking at quotes for new machinery, it’s wise to take a close look inside the plant and identify the signs that the current equipment has reached its limits.

7 Clear Signs That Your Machinery Needs an Upgrade 

Increasingly Frequent Breakdowns

When unscheduled downtime has become the norm, it’s a sign of structural wear and tear. If a machine starts failing more frequently than it did a year ago, this trend rarely reverses with routine maintenance alone. 

Rising maintenance costs

There comes a point where maintaining a machine becomes more expensive than replacing it. If spending on repairs, replacement parts, and technical labor rises year after year without any improvement in production, that trend warrants analysis based on actual data, not intuition. 

Decline in production or final product quality

An aging machine doesn’t always break down—sometimes it simply performs less efficiently. Less precise tolerances, slower cycles, or products that require more labor are signs that the equipment no longer meets current production demands. 

Difficulty in obtaining replacement parts

When a manufacturer discontinues parts or delivery times stretch out for weeks, reliance on outdated equipment becomes a real operational risk. 

Incompatibility with new production requirements

If the company has grown, diversified its product line, or needs to integrate into more automated processes, a machine designed for a different production reality becomes a bottleneck—no matter how well it may have performed in the past. 

Safety risks or certification issues

Industrial safety regulations are constantly evolving. Equipment that does not meet current standards exposes your business not only to operational risks but also to legal and liability risks. If you have any doubts about whether your machinery complies with current regulations, now is the time to have it reviewed by a specialist. Our machines meet the highest safety requirements. 

The competition has already made the leap 

When other companies in the industry upgrade their production lines, the difference in efficiency quickly becomes apparent in delivery times, costs, and responsiveness. This isn’t necessarily cause for alarm, but it is an indicator of where the market is headed. 

Upgrade, repair, or keep waiting: how to make an informed decision

Not all of the above signs mean the same thing, nor do they all require the same response. Before deciding, it’s wise to analyze: 

• The equipment’s actual remaining useful life, beyond its nominal age. 
• The cumulative maintenance cost over the last 12–24 months, compared to the cost of replacement. 
• Impact on production: downtime, losses, delays, and their effect on revenue. 
• The current equipment’s ability to adapt to the company’s future needs. 

This is precisely where an external technical assessment adds the most value: it allows you to distinguish between perception (“the machine is already old”) and actual data (“the machine generates an additional cost of X euros per month and a Y% risk of downtime”). 

What does a well-planned replacement offer (beyond just a new machine)?

Renewing industrial machinery should not be viewed simply as replacing one piece of equipment with another, but rather as an opportunity to thoughtfully redesign the production process. A well-planned renewal allows for: 

• Achieve real efficiency gains in each production cycle. 
• Reduce errors and waste associated with worn-out equipment. 
• Optimize entire processes, rather than just replacing a single component. 

Provide a comprehensive solution tailored to the plant’s specific needs, rather than a standard machine that forces the process to adapt to its limitations. 

At DAC Industrial, we don’t start with a fixed catalog: we design and manufacture custom machinery, tailored to solve each client’s specific production challenge, not to fit it into a generic model. 

If you recognize any of these signs in your plant, the first step isn’t to buy a new machine—it’s to use data to understand what it’s really costing you to keep using the current one. Request a technical assessment from DAC Industrial, and we’ll help you determine whether your machinery needs upgrading, using professional criteria and with no obligation. 

Write to us, and we’ll analyze your situation. 

For many companies, the challenge is not just having machinery up and running, but ensuring it maintains stable and reliable performance over time. It is in this context that preventive maintenance is seen not as an expense, but as an industrial management tool.

The real problem when a machine stops

Murphy's Law. A breakdown can happen at the worst possible time: during a production peak, with orders in progress, or when the line is running at full capacity. How we resolve the issue, and the tools we have at our disposal, is what distinguishes companies that manage equipment from those that focus on managing production.

Therefore, if you want to reduce technical incidents in your production plant and their collateral effects (lower efficiency, more errors, increased operational pressure, and a potential impact on overall performance), you must invest in preventive maintenance of equipment and machinery.

What exactly is preventive maintenance?

Preventive maintenance is the set of planned actions taken on a machine or facility to prevent a breakdown from occurring. The goal is to detect wear, misalignments, or anomalies in time and correct them before they turn into an unplanned shutdown.

Preventive Maintenance vs. Corrective Maintenance

The difference is simple:

• Corrective maintenance: action is taken after the problem has already occurred, that is, when the machine has already stopped working.
• Preventive maintenance: it's carried out before the problem impacts production.

In the short term, it may seem more convenient to "fix problems as they arise." But in practice, this logic tends to create more urgency, more improvisation, and less control. 

How to perform maintenance?

Waiting for a breakdown to occur usually ends up being more expensive

When you only intervene when something fails, the cost you have to bear isn't just the repair. There are also costs in terms of:

• diagnostic time,
• loss of production pace,
• replanning,
• possible impact on quality,
• and dependence on an urgent response.

In contrast, a well-defined preventive plan helps you work with more foresight and less operational stress.

How Preventive Maintenance Impacts Production Continuity

The value of preventive maintenance should not be measured only by the parts replaced or inspections performed, but by what it prevents:

• Fewer unplanned downtime. This is the first major advantage. If you regularly inspect a machine's critical points, it's easier to detect symptoms before they turn into a failure. 
• Greater stability in line performance. A production line doesn't just need to run; it needs to do so consistently. When equipment is inspected, adjusted, and properly maintained, the line's performance tends to be more stable and predictable.
• Better equipment lifespan and less premature wear and tear. Proper maintenance also helps protect your investment. 

Signs that your plant needs a preventive plan

There are still many companies that think, "as long as everything is working, there's no need to touch anything." The problem is that the change of heart happens by force and comes too late. Some indicators worth reviewing are:

• Recurring incidents. If the same machine experiences issues repeatedly, no matter how small, it's not a coincidence: it's a warning.
• Excessive reliance on emergency repairs. When maintenance always comes in the form of an emergency, the problem isn't the repair: it's the lack of planning.
• Lack of traceability, spare parts, or clear routines. If there is no defined criteria for what to inspect, when to do it, or which spare parts to have available, the operational risk increases.

What elements should a good preventive maintenance plan include

Not all equipment requires the same level of monitoring. But, in general, a well-designed plan should include at least these points:

• Inventory of critical equipment. You need to know which machines have the greatest impact on production continuity and prioritize them.
• Maintenance schedule. It's not about doing maintenance "whenever you can," but about defining realistic frequencies based on usage, workload, and criticality.
• Lubrication, adjustments, cleaning, and inspections. These types of actions are part of the most basic maintenance, but they are often what prevent major problems.
• Key spare parts and technical criteria. Not all spare parts need to be in stock, but it is advisable to identify the most sensitive or critical components to reduce response time in the event of a failure.

When it makes sense to have external technical support

Some plants have a very capable in-house maintenance team. But there are also cases where working with external support provides additional expertise, specialization, or responsiveness. At DAC Industrial, we offer this additional support with our team, which has extensive experience in machinery repair.

This is usually especially useful when:

• there are custom-made equipment or specific installations,
• specialized technical diagnosis is needed,
• you want to implement a more rigorous preventive maintenance plan,
• or you are looking for a partner who understands both the machine and its production impact.

Conclusion: prevention is protecting production

Preventive maintenance is not just a recommended technical practice; it's a management decision that directly affects production continuity. In a demanding industrial environment, preventing means reducing unplanned downtime, working more organizedly, protecting equipment, and gaining operational stability. At DAC Industrial, this is how we understand our work.

And, above all, it means moving from a reactive approach to a proactive one.

If your company wants to reduce the risk of production downtime and define a preventive maintenance plan for industrial machinery with technical expertise, at DAC Industrial we offer maintenance, repair, and spare parts supply services that work to improve the production of our clients' industries.
