The Next Step in Hot End Inspection!



The ISWatch system is an easy to use, multi Infrared Camera system for:

  • Hot End Inspection
  • Process Monitoring
  • Process Control

The ISWatch system uses one, two or more small infrared cameras to create thermal images of hot glass products directly after the glass forming machine.

The system rejects critical defects like:

  • Fins
  • Bird swings
  • Spikes
  • Freaks

The system also provides real time cavity related information for optimizing the:

  • Glass Distribution
  • Glass Temperature
  • Glass Symmetry
  • Lean
  • Diameter / Shape

All information is displayed on the user friendly Touch Screen.


End Reject

Glass products with defects can be rejected directly after the glass forming machine.

The ISWatch rejects glass products with:

  • Fins
  • Bird swings
  • Spikes
  • Freaks
  • Stones
  • Bubbles and blisters
  • Choked necks
  • Wedged bottoms
  • Lean
  • Thin glass
  • Thick glass
  • Stuck ware
  • Fallen ware
  • Shape and diameter problems


Data Analysis / Industry 4.0

All measurement data of the ISWatch system is stored in a database. The data can be easily retrieved and displayed, making it possible to compare job runs and to perform statistical data analysis.

Issues with the production from days or months ago can be tracked and analysed.

Customer information systems can be easily connected to the ISWatch system.


of Use

Inspection systems at the hot end must have a high performance but also should be easy to use. We continuously are working together with our customers to make the best system on the market. The result is a system which has the following key features:

  • Easy to Use Touch Screen interface
  • Self-Explanatory (limited training necessary)
  • Automatic Camera set-up
  • Easy synchronisation to the IS-Machine
  • Easy to Use Operator Level
  • Easy to Use Specialist Levels



The infrared cameras of the ISWatch system are the smallest on the market, they measure only 14cm x 14cm x height.

The small size of the infrared camera creates the possibility of putting two or more at the Hot End, making a total hot end inspection feasible.

Cooling of the cameras is easy and can be done with with cooling air or compressed air.


Our software and hardware engineers work closely together with our customers to adapt the ISWatch system to their specific needs.

Software modules can be hidden when not used in order to simplify the use and set up of the system.

Because our cameras and housings are developed in-house, we have the possibility to customize the infrared cameras to a specific Hot End situation.

GobWatch Communication

The ISWatch can communicate with the GobWatch system and display gob measurement data. This makes it possible to correlate the Glass Forming Process with the Gob Forming Process. For example, changes in the glass distribution can be correlated to changes in the gob weight, gob temperature and gob shape.

Job data is also exchanged, a job change has to be performed only on one system (GobWatch or ISWatch), the other system is automatically set up and configured speeding up the job change procedure!

Swabbing Robot Control

The ISWatch system can interface with swabbing robots and send the swabbing robot to a mould which needs to be swabbed.

The decision to swab a particular mould and how much swabbing material is used, is based on the ISWatch measurement of:

  • Glass Distribution
  • Glass Symmetry
  • Bottle Lean
  • Bottle Shape
  • Inclusions
  • Glass Temperature

The closed loop system can also use the measurement information of the gobs (GobWatch) and the moulds (BlankWatch) to further improve the robot swabbing process.



  • Reject of critical defects
  • Small Camera Housing (14cm x 14cm footprint)
  • More than 2 Infrared Cameras possible for better detection and rejection of critical defects
  • State of the Art User Interface
  • Faster Job Change
  • Higher Product Quality
  • Higher Productivity
  • Fast Payback time



  • Multi product operation
  • Tandem IS-Machine operation
  • 1 or more air cooled infrared cameras
  • Industrial Touch Screen
  • Remote electronics and computer cabinet
  • Remote diagnostics and support
  • Easy maintenance and service (Plug and Play hardware modules)

The TopWatch system can be fully integrated within the ISWatch system.
