An Advanced Control System for Heat and Vacuum Sealers*

The iS2 (Intelligent Sealing System) is a platform that utilizes an advanced Siemens PLC, Siemens HMI, and proprietary pneumatic and electrical components to produce heat/vacuum heat seal solutions.

The iS2 System delivers precise controls of time, temperature and pressure, with options to store seal recipes for repeated use. Originally developed to answer the need for validation in medical pouch sealers, the iS2 platform quickly expanded beyond tabletop units as we introduced customers to the range of controls available with such a system.

*Impak is capable of retrofitting this system on the equipment it builds, as well as, competitor's equipment for a thermal impulse heat, vacuum sealers, or constant heat sealing systems

Available iS2 Interfaces

IMPAK currently uses 3 different Siemens HMIs with the iS2 System. The HMI used is determined by the size of the machine; tabletop machines utilize the smaller touchpad HMI, whereas large frame machines utilize the touchscreen HMI. Read more about the benefits of the iS2 below.




Standard Touchpad Touchscreen Advanced Touchscreen

Our most used HMI for the iS2 System. Compact and compatible with small tabletop units. Stores 1 recipe.

This mid-size HMI is a slight upgrade from the standard touchpad with fewer keys and more recipe storage; stores up to 100 recipes.

A convenient 7" touchscreen HMI, compatible with large frame machines. Graphs time/temperature. Stores 500 recipes.


Benefits of an iS2 System

Convenient Control - Advanced Siemens HMIs with Settings, Auto and Manual Test Menus. Touchpad or Touchscreen operation.

Temperature Accuracy - For legal reasons we claim “±3” degree temperature accuracy, but most tests show the accuracy of ±1 degrees F. The system takes temperature readings every 1-2ms.

Pressure Accuracy - Pressure control with 0.1PSI consistency and high tech proportional valve. Control high and low pressure from the HMI.

Time Accuracy - Adjust seal time in 1/10 second increments directly from the HMI.

Independent Thermocouples - Set independent thermocouple temperatures directly from the HMI.

Recipe / Formula Storage - A recipe is defined as the precise formula for temperature, pressure, and sealing parameters required for a specific material and application. Some companies in the industry refer to this formula as a recipe. We're uncomfortable with the term recipe used in this application since it implies vagueness, e.g., terms similar to 'pinch of salt' and a 'dash of vinegar' would not be acceptable. Since it is our nature to be specific and accurate for delivering technical solutions at IMPAK Corp, we refer to them as formulas. Wouldn't you rather be able to set your seal heat temperature at 243.7 deg F (117.61 C)?

Case Study: Upgrading to an Intelligent Sealing System Platform

Challenge: IMPAK was contacted by a large firm that manufactures plastic films with a challenge; upgrade a hand held heat sealer with old technology TIC (temperature impulse controller) and timer so that precise heat and cool temps can be measured and monitored. The heat sealer is used in their QC Lab and research and design lab to construct and test prototypes. [see full article]

Compatible Sealers

IMPAK can make any size table top (15", 20", 25" 31.5", 36", 51", 61") and industrial (36", 48", 60", 72", 84", 86", 96", 110", 210" and more) heat/vacuum heat sealer with this platform.
