Pressure Testing and Leak Detection Machines

We design and manufacture machines and test stations for pressure testing and leak detection for industrial production. Each solution is tailored to the specific part, manufacturing process, and customer requirements, from laboratory testing to fully automated high-volume production.

What Is a Pressure Test

A pressure test is used to verify the tightness of a part’s sealed internal volume. The test volume is sealed, pressurized, and then monitored over time after isolation.

Pressure Test Principle

  • Seal the part using a fixture
  • Pressurize to a defined pressure level
  • Close the volume and isolate it from the pressure source
  • Dwell time with measurement
  • Evaluate pressure drop, flow rate, or perform visual inspection in a water bath

Leak Tightness Measurement Methods

We provide the following types of pressure tests:

  • Water bath test
    Visual detection of escaping bubbles. The only method that enables precise leak location.
  • Pressure decay measurement
    Automatic evaluation using a pressure sensor and PLC.
  • Leak detection (e.g., ATEQ)
    High-sensitivity measurement of volume change and flow in the tested part..

Laboratory and Production Testing

Laboratory testing

  • • Manual clamping of parts
  • • Low quantities
  • • Individual evaluation
  • • Longer test time

Production testing

  • • 100% testing of production output
  • • Short and stable production cycle
  • • Elimination of operator influence
  • • Clear PASS / FAIL result

The goal is to transfer laboratory testing into a fully repeatable production process.

Types of Pressure Testing Machines

Universal test machines

One platform for different part types, with easily replaceable fixtures.

  • Leak location in a water bath
  • Two separate workstations for higher productivity
  • Automatic recipe detection based on fixture type
  • Marking OK parts with a stamp
  • Test pressures: 1-10 bar or 1-4 bar

Dedicated machines and fixtures

Equipment designed specifically for a particular part.

  • Leak tightness test for aluminium castings
  • Test station with ATEQ leak detectors
  • Two workstations with automatic clamping
  • Marking OK parts
  • Test pressures: 3 bar

High-pressure test stations

Stations designed for testing high-pressure vessels:

  • Maximum test pressure 150 bar
  • Leak location in a water bath
  • MAXIMATOR high-pressure system
  • Safety tray with bullet-resistant glass
  • TIČR certification

From design to certified machine

We have been developing and manufacturing test stations and machines for pressure testing since 2015. 
We provide a complete solution - from the initial concept through production to final certification and commissioning. Each machine meets applicable standards and legislative requirements.
