Technical service of volumetric filling, weighing and counting machines

Specialized assistance for volumetric filling machines, weighing and counting machines with coverage in Spain and technical support for industrial projects of food, granules and snacks, powders and dry products, pet food, light chemicals, cosmetics.

Diagnosis, repair and maintenance for volumetric filling, weighing and counting machines

We work on filling and weighing machinery where precision is critical: volumetric systems, weight filling, electronic counting and multihead systems for solid or granulated product.

The goal is not just to repair the breakdown. We also aim to stabilize the dosing, restore production rates, reduce waste, and ensure the machine is aligned with the customer's actual product format and specifications.

We intervene in mechanical, electrical, pneumatic and parameterization incidents, in addition to preventive checks aimed at avoiding weight deviations, counting errors and repetitive stops.

Equipment and variants we support

Volumetric piston fillers, linear and rotary fillers, weighing scale fillers, electronic solid counters, multihead weighers, dosers synchronized with packaging

How to apply technical support

The better the information we receive from the team, the faster we can guide diagnosis, spare parts and intervention plan.

1. Send model and process

Please specify the type of machine, the product it dispenses, the format, the target production, and whether it works by volume, counting, or weighing.

2. Attach photos and video

It helps us to receive short video of the work cycle, HMI, active alarm, hoppers, heads and discharge or sealing area.

3. Describe the failure with data

Explain if the problem is related to weight, dripping, misalignment between printheads, count jumps, recipe, line stoppage, or lack of synchronization.

4. We coordinate intervention

Based on that, we assess spare parts, pre-diagnosis, need for a visit, remote adjustment, or comprehensive line review.

Conditions of technical service

Priority ARC teams

Priority attention is given to ARC equipment and machines where there is clear traceability of components, warranty and spare parts.

Other brands and retrofit

We also consider other brands when there is a real option for repair, recalibration, or partial retrofit without compromising reliability.

Line-focused intervention

We don't treat the machine as an isolated element: we check product feeding, synchronization with packaging, rejection, weighing and evacuation.

Technical and coverage policy

Priority for ARC teams: Yeah.

Other brands: Equipment from other brands is considered based on the availability of spare parts, electrical/pneumatic documentation, and the actual feasibility of adjustment.

Coverage: National coverage and international support under planning, especially when there is a need for calibration, format adjustment or integration with the rest of the line.

Guarantees and maintenance

Guarantee on intervention

The specific coverage depends on the type of repair, parts replaced, and the previous condition of the equipment.

Preventive maintenance

Recommended when the line works with tight weight tolerances or multiple recipes and format changes.

Calibration and monitoring

In weighing machines and multihead weighers, it is crucial to check stability after intervention, not just to close the specific fault.

Technical guides and maintenance criteria

Consistent preventive maintenance on multihead weighers and industrial volumetric fillers
Preventive Maintenance

What to check before a filler or weigher starts diverting production

Weight or volume deviations rarely appear suddenly. They are usually preceded by small symptoms: dripping, variations between cycles, unbalanced printheads, poorly fed product, or unstable readings.

A preventive check should include technical cleaning, load cell verification, pneumatic control, valve condition, line synchronization, and actual product testing.

  • Verification of weight/volume tolerances
  • Vibration check and feed flow rate
  • Checking sensors and alarms
  • Review of recipes and active formats
Realistic fault diagnosis in industrial counting and multihead weighing machines
Technical Guide

Typical faults in counters and multihead counters that affect the final quality

In counting and multihead machines, the problem is usually not a total breakdown, but a progressive loss of reliability: double counting, repeated underweighting, jammed product, excessive rejection, or desynchronization with the bagging machine.

Proper repair involves a combination of electrical, mechanical, and process diagnostics. If only a part is replaced without reviewing the product's behavior and the recipe, the problem will usually return.

  • Incorrect count due to sensor or vibration
  • Misalignment between weighing heads
  • Poor discharge due to gate or opening time
  • Stops due to lack of synchronization with the line

Basic technical checklist

  • hoppers and feeders
  • load cells
  • weighing heads
  • photoelectric sensors
  • PLC and HMI
  • pneumatic valves and actuators
  • motors, gearboxes and variators
  • synchronization with transport and bagging machines

Frequently Asked Questions

Do you service multi-head printers even if they are not ARC?+

Yes, provided there is real technical feasibility, access to spare parts, or the possibility of safe adjustment/calibration.

Can you help if the problem is weight-related and not an obvious breakdown?+

Yes. In fact, many interventions focus on weighing stability, repeatability, and shrinkage reduction, not just breakage.

Do you also check the synchronization with the bagging machine or conveyor belt?+

Yes. In this type of machinery, the failure usually stems from the integration between equipment, not from an isolated module.
