Modern production demands higher precision and efficiency than ever before. Traditional hydraulic and pneumatic presses often cannot keep up, especially when working with small or complex parts. Operators often deal with noise, oil leaks, and limited control over pressing force. To solve these problems, many manufacturers are turning to small servo presses.
Een kleine servopers gebruikt een elektrische servomotor om beweging, kracht en positie zeer nauwkeurig te regelen. In plaats van te vertrouwen op olie of lucht, wordt een programmeerbare elektronische besturing gebruikt. Dit geeft gebruikers meer flexibiliteit en herhaalbare resultaten. Het is zeer geschikt voor industrieën die precisie, datatracking en consistente krachtregeling vereisen.
Small servo presses are changing how manufacturers perform pressing, fitting, and assembly work. Their precision, energy savings, and ability to record process data make them a smart choice for modern production lines.
Understanding Small Servo Press Technology
Small servo presses bring electric precision and digital control to today’s production lines. They combine accurate motion, clean operation, and programmable force control — making them ideal for precision assembly and forming.
Working Principles of Servo Presses
A small servo press works with an electric servo-driven system. The servo motor turns electrical energy into rotary motion, which passes through a ball screw or gear drive to create a linear pressing force.
During each cycle, sensors and encoders constantly track torque, position, and speed. The controller checks this data against a programmed force–displacement curve and makes real-time adjustments. This closed-loop system keeps accuracy within ±0.005–0.01 mm.
For example, in PCB connector insertion, a 5 kN servo press can control insertion depth at slow speeds (1–3 mm/s) to avoid damage to copper pads. Each cycle is recorded, providing full traceability.
Typical Operating Parameters:
| Parameter | Range | Beschrijving | Example Use |
|---|---|---|---|
| Pressing Force | 0.5 – 30 kN | Adjustable per cycle | Connector assembly, small forming |
| Position Accuracy | ±0.005 – 0.01 mm | Closed-loop control | Micro-fit or precision crimping |
| Speed Range | 0.1 – 200 mm/s | Fully programmable | Slow approach or high-speed press |
| Curve Sampling Rate | 1–2 kHz | Real-time bewaking | Detects resistance anomalies |
| Geluidsniveau | ≤65 dB | Quiet, clean operation | Lab and cleanroom use |
This flexibility allows a servo press to handle many materials — from soft aluminum enclosures to stainless steel parts — without manual tuning.
Key Components and Design Features
Each small servo press combines strong mechanics with digital intelligence:
- Servo Motor: Provides torque instantly for smooth motion and precise speed control.
- Ball Screw Drive: Converts rotation into accurate linear motion with low backlash, keeping repeatability over thousands of cycles.
- Controller: Sets pressing force, dwell time, and motion profile. Advanced types can save many customized programs.
- Feedback System: Uses torque sensors, load cells, and encoders for continuous correction, ensuring stable results even with material changes.
In an EV sensor housing assembly line, for example, a 10 kN servo press with built-in feedback detects friction spikes during press-fit operations. This signals possible misalignment or burrs. The system stops automatically, preventing part damage and saving time.
Comparison with Hydraulic and Pneumatic Presses

Elektronica assemblage
In electronics manufacturing, servo presses are widely used for PCB connector insertion, terminal crimping, and solderless joining. These tasks demand accurate control to avoid stress on solder joints or cracks in fragile components.
A 3 kN tabletop servo press can manage insertion depth within ±0.01 mm and apply force in 0.2 N steps, which suits smartphone or sensor PCB assembly. Each cycle records a force–displacement curve, letting engineers detect resistance spikes or missed insertions instantly.
Productie medische apparatuur
The medical industry needs clean, precise, and validated production. Servo presses meet these requirements with oil-free operation, low noise, and continuous data recording. They are often used for implant assembly, catheter connector pressing, and micro-valve sealing.
A 1 kN benchtop servo press maintains force accuracy within ±0.5%, protecting delicate titanium and polymer parts from deformation. Press data can be stored under ISO 13485 and FDA 21 CFR Part 11 standards for traceability.
Automotive and EV Battery Production
Servo presses play a major role in automotive and EV battery assembly, including terminal pressing, sensor housing assembly, and module compression. Consistent force helps maintain uniform contact resistance and long-term durability.
A 20 kN servo press can keep force variation within ±0.3% and handle strokes up to 150 mm. When linked to PLC systems, it allows engineers to monitor pressing data for each battery cell — supporting EV traceability and safety compliance.
Laboratory and R&D Prototyping
In labs and research centers, servo presses are used for material testing, forming studies, and joining experiments. Their programmable motion profiles and precise feedback make them ideal for prototype evaluation.
For instance, a university research lab used a 2 kN servo press to test the joining strength of carbon fiber composites. The system recorded deformation curves to optimize part geometry before mass production.
Thanks to quiet operation (≤60 dB) and oil-free design, servo presses are also suitable for cleanrooms and educational environments where cleanliness and precision are required.

Small servo presses have proven to be reliable tools across these sectors. Their programmable precision, clean performance, and real-time feedback continue to drive better quality and process efficiency in modern manufacturing.
Key Advantages and Performance Benefits
Small servo presses deliver proven improvements in accuracy, energy use, and long-term reliability. Their digital control systems give engineers detailed feedback, keeping product quality consistent through thousands of production cycles.
Precision and Process Control
Servo presses manage both force and position at the same time using closed-loop feedback. Position accuracy reaches ±0.005–0.01 mm, while force repeatability stays within ±0.5%. This allows engineers to program specific press profiles — such as slow approach, pressure hold, or smooth release — for each product.
In a battery terminal line, a 10 kN servo press detected when a terminal wasn’t fully seated by comparing its curve with the reference. When displacement shifted beyond 2%, the machine stopped automatically, preventing damage or rework.
| Control Parameter | Typical Servo Press Value | Improvement vs. Traditional Press |
|---|---|---|
| Position Accuracy | ±0,005 mm | 10× better than pneumatic |
| Force Accuracy | ±0.5% | 6× better than hydraulic |
| Cycle Repeatability | ≥99.8% | Stable under varying loads |
| Detection Response | <5 ms | Real-time defect prevention |
This level of precision keeps fit and force consistent, builds production reliability, and supports automation-friendly manufacturing.
Gegevensverzameling en kwaliteitstraceerbaarheid
Each press cycle produces a force–displacement curve, serving as a digital signature of the process. Engineers use these curves to confirm forming consistency, evaluate joint behavior, and ensure compliance with quality standards.
Servo presses can send data via Ethernet, USB, or OPC UA, connecting easily to MES, QMS, or SPC systems. This supports full traceability under standards such as ISO 9001, IATF 16949, and FDA.
A real-world example comes from an automotive electronics supplier that linked its servo presses to the MES. Within six months, the company cut manual inspection time by 40% and improved first-pass yield by 18% through early detection of force curve changes.
Energie-efficiëntie en schone werking
Hydraulic systems draw constant power, even when idle. Servo presses use energy only while moving, cutting consumption by 30–70% depending on cycle setup. With no oil or compressed air, they avoid leaks, spills, and excess noise, keeping the workspace cleaner and safer.
| Energy & Environmental Comparison | Hydraulische pers | Pneumatic Press | Servopers |
|---|---|---|---|
| Energieverbruik | 100% (baseline) | 90–100% | 30–70% |
| Power Source | Oil Pump | Luchtcompressor | Electric Motor |
| Onderhoudskosten | Hoog | Medium | Laag |
| Workplace Noise | 80–90 dB | 85–95 dB | 60–75 dB |
| Milieu-impact | Oil Waste | Air Leakage | Clean, Oil-Free |
In one medical device plant, replacing five 5 kN pneumatic presses with servo presses cut yearly energy use by 5,200 kWh and removed downtime caused by air leaks. That saved roughly USD 1,800 per year in power and maintenance.
Reduced Maintenance and Noise
Servo presses have fewer moving parts and no fluid circuits, extending maintenance intervals by 30–40%. With no pumps or valves, unplanned repairs become rare.
Noise levels usually stay under 65 dB, suitable for labs and clean assembly areas. Operators can talk easily during operation, improving comfort and focus.
Across a five-year period, servo presses can lower total operating costs by 25–35% while keeping OEE (Overall Equipment Effectiveness) stable and predictable.
Selection Guidelines for a Small Servo Press
Choosing the right small servo press means balancing force, motion control, and data capability with your production goals. A careful selection ensures reliable operation, less downtime, and a longer machine life.
Determine Application Requirements
Start by defining your basic needs — pressing force, stroke length, speed, and accuracy.
For small assemblies like electronic connectors, a force under 2 kN is usually enough. Structural parts or terminal joints often require 10–30 kN.
Stroke depends on part geometry. A short stroke (30–60 mm) gives better precision for small parts, while a long stroke (100–150 mm) fits deeper forming or insertion tasks.
Speed settings are also important. Servo presses allow a slow approach (1–5 mm/s) for alignment and a fast return (up to 200 mm/s) for productivity. These settings can be changed through software, not hardware.
| Type toepassing | Typical Force (kN) | Stroke (mm) | Recommended Speed Profile | Voorbeeld |
|---|---|---|---|---|
| PCB connector pressing | 0.5–2 | 30–50 | Slow press, fast return | Electronics assembly |
| Bushing or bearing fit | 10-20 | 80–120 | Constant force | Automotive |
| Medical housing seal | 1–5 | 50–80 | Hybrid (position + force) | Medical device |
| Material forming test | 2–10 | 50–100 | Constant speed | R&D lab |
These figures give a useful starting point for selecting a press that fits your process accurately and safely.
Evaluate Control and Feedback Features
The control system defines how precise the press will be. Choose a model with real-time feedback from load cells, torque sensors, and encoders.
Look for presses that can switch between force-based, position-based, and hybrid (force + position) modes.
Modern controllers include features like curve comparison, auto-stop when deviation occurs, and OK/NG evaluation after each cycle. Data output through CSV, USB, or Ethernet helps connect the press with SPC or MES systems for continuous monitoring.
Example: A supplier integrated a 10 kN servo press with its PLC network. The system checked each press curve against reference data and flagged out-of-spec parts within 3 ms, improving inspection speed by 35%.
Consider Integration with Automation Systems
Today’s production lines rely on connected machines. A quality servo press should work easily with robots, PLCs, and automated lines using open communication systems like EtherCAT, PROFINET, or OPC UA.
This setup allows synchronized motion, faster changeovers, and automatic data collection.
For example, in an EV module line, servo presses connected via PROFINET to robot arms cut manual alignment steps by 60% and kept press-fit accuracy stable across shifts.
When checking automation compatibility, make sure the press supports external I/O signals, safety interlocks, and HMI interfaces for easy parameter control.
Review Safety, Ergonomics, and Standards
Safety and comfort are key for operators. Choose presses with light curtains, two-hand start, emergency stops, and overload protection.
Make sure the press follows standards like CE, ISO 12100, and UL.
For small workstations, tabletop or benchtop presses are practical. Touchscreen interfaces and adjustable height designs help reduce operator fatigue and improve workflow efficiency.
Meeting safety and ergonomic standards protects people, boosts productivity, and reduces unexpected downtime.
