In the hydraulics industry-manufacturers of valves, pumps, filters, and cylinders-component marking is almost never the first choice. Surfaces are often curved, chrome-plated, oiled, or of such dimensions that it is impractical to secure the finished product on the machine. The most common solution, for anyone producing a few dozen to several thousand parts per day, is to mark a steel or aluminum plate that is then applied to the product body. It is a winning technical compromise: you separate the marking process from the assembly line, standardize the substrate, and achieve repeatable and legible part identification, even after painting or exposure to hydraulic fluids.
However, when you get into the practicalities of a nameplate marking project for hydraulics, you soon realize that the real bottleneck is not the laser, nor the pick-and-place system, nor the number of loaders: it is the software that manages what to mark, on which nameplate, at what time, and for which production order. This is where, in our experience, the decision is made whether the system becomes a productive asset or an underutilized machine.
The context: different plates, every day, from the same machine
A typical hydraulic manufacturer maintains catalogs with hundreds of part numbers. A directional valve, a pressure reducer, and a hydraulic filter have nameplates with different layouts, different contents, and different brand names even within the same company. The nameplate typically carries part number, serial number, lot, production date, pressure rating, flow rate, CE marking, any ATEX or PED symbols, a Data Matrix for traceability, and-almost always-a brand logo. Changing the production order changes the layout; changing the lot changes the alphanumeric data; changing the destination line may change the marked regulatory requirements.
To have the operator handle this manually-loading the right marking file each time and typing in variable data-is to accept an unacceptable risk of error for a company working with regulations such as PED Directive 2014/68/EU or internal traceability standards borrowed from automotive. The correct technical answer is to automate the data flow between the management system and the marker.
Tag Marker: an application layer between ERP/MES and marker
Tag Marker is the interface software that we install on LASIT’s dedicated tag marking machines-from basic one-loader configurations up to four-loader systems with orderly unloading. It functions as an application layer that comes between the marking software (FlyCAD) and the customer’s information system, be it an ERP (SAP, Microsoft Dynamics, proprietary management systems), an MES, a line supervisor, or a simple departmental database.
The operating principle is based on a boundary table: a shared data structure-CSV file, table on SQL Server, view on Oracle, REST web service, read via OPC-UA-to which the ERP writes the work order and from which Tag Marker reads the information needed to populate the marking. On the input side, the software typically receives the production order, the part number, the number of tags to be produced, the layout to be retrieved, and the set of dynamic variables (serial number progressive, lot, date, functional parameters). On the output it returns the successful marking, any Data Matrix reading outcomes via integrated verifier, error codes, production counters.
This architecture solves in one fell swoop three critical issues recurring in the industry:elimination of manual transcription, automatic selection of the correct layout based on the part number, and process traceability-each tagged tag is recorded with timestamp, laser parameters used, operator ID, and reference order.
What does “customizable” mean in concrete terms
Each hydraulic installation is its own case. Tag Marker is not a shelf product but a platform that our software department adapts to customer specifications. In the analysis phase we typically define: data exchange protocol (shared file system, SQL queries, API, MQTT), mapping rules between ERP fields and tagging layout fields, behavior when there are no orders in the queue, management of print queues with multiple priorities, events to log, KPIs to expose.
On the topic of KPIs, it is common to be asked to display metrics such as marked plates per shift, average cycle time, DMC quality detection rate below threshold (ISO/IEC 15415 or AIM DPM-1-2006 reference), machine downtime with associated causation. This data can be accessed at the machine, exported as periodic reports, or returned to the MES to feed plant dashboards.
A realistic application example
A European proportional valve manufacturer needs to mark about 400 50×30 mm AISI 304 stainless steel plates per day, on 18 separate part numbers. Typical configuration: one marker with double loader and tidy discharge, FP 30W fiber laser with FFL160 focal length, average marking time 6 seconds per tag. Tag Marker reads an SQL view fed from the MES every 30 seconds, unloads rows not yet processed, dynamically populates part number, sequential serial number, Data Matrix with ID field conforming to internal standard and CE symbol. When marking is complete, the integrated verifier grades the DMC; if the grade falls below B, the tag is discarded and the event logged. At the end of the shift, an automatic PDF report is deposited on the company server.
Typical mistakes to avoid in the design phase
The first is underestimating the data flow analysis phase. Often the customer comes in with the request “we connect to the management system,” but the company does not yet have a field that exposes the part number in the format required by the layout, or the MES does not handle the serial number. This activity needs to be addressed before the order is placed, with the customer’s IT department.
The second mistake is sizing the loader without considering order variance. A machine with a single loader is fine for homogeneous cycles, but it becomes a limitation if orders change plate size several times a day. In those cases a double or quadruple loader is the correct choice.
The third mistake is to consider software as an accessory. In hydraulics, where the added value of the marker almost always comes from its integration into the company’s information process, the software is the part that determines the success of the project.
In summary
If you manufacture valves, pumps, filters, or hydraulic cylinders and need to manage the marking of plates with variable contents related to production orders, the choice of laser and loading system is only the starting point. The deciding factor is the level of integration between the marking machine and your ERP/MES. A machine properly configured on the hardware side but with a generic software interface does not exploit its potential; conversely, a system with well-designed software sized to the customer’s actual flows works autonomously, reduces transcription errors and provides process data that can be used for quality and production.
