Pressure Recording Film

Impression Record Before Analysis

Impression Record After Analysis

Create an instant, permanent image of pressure distribution and magnitude. These sheets of film help you identify uneven pressure that can lead to leaks and stress fractures. Use them between any two surfaces that touch each other, such as bolted joints, welding fixtures, and jigs. Tiny capsules within the film burst at specific pressure levels, causing the film to change color. This produces an instant map of pressure variation, similar to a heat map. For a custom size, cut the film with scissors.

Pressure Film

Film that includes two sheets must be used together.

Pressure variance analysis kits include a sheet of pressure film and instructions on how to send your film to the manufacturer for analysis. The manufacturer runs the analysis through specialized software. This software gives you more accurate results than the color correlation manual. Within a few days of sending your sample in, you’ll receive an email with a full report on the force distribution and magnitude.

Use a color correlation manual (sold separately) with pressure film to determine the magnitude of the pressure measurements. The manual includes best practices and color correlation charts to help you match the colors on your film readout to the correct values.

A color sample pack includes one 3" × 4" piece of film in each of these pressure ranges: 28-85, 70-350, 350-1,400, 1,400-7,100, and 7,100-18,500 psi.

Roller Impression Analysis Kits

Roller impression analysis kits are also known as NIP impression kits. They include three sheets of film, a color correlation manual specific to roller systems, and a shipping envelope to send your film in for analysis. The manufacturer runs the analysis through specialized software. This software gives you more accurate results than the color correlation manual. Within a few days of sending your sample in, you’ll receive an email with a full report on the force distribution and magnitude.

0.007" thick film includes two 0.0035" thick sheets that must be used together

Pressure Testing Analysis Systems

Analysis System

Windows Compatible Software

Take lab-quality scans of pressure recording film for frequent onsite measurements. These systems detect color changes in the film to spot issues that can cause leaks and stress fractures. They’re often used with bolted joints, metal stamping, and nip rollers to measure and adjust for uneven pressure when setting up a new job. They’re also known as TOPAQ analysis systems. The scanner comes calibrated for reading pressure recording film.

The included software renders color pressure images in detail for more accurate results than visual inspection with a color correlation manual. You can create 3D images, grids, and graphs. Zoom in for a closer look at the pressure distribution throughout your system.

This is not a finite element analysis (FEA) tool. While an FEA tool uses models to predict stress and potential failures, these evaluate pressure based on your actual system. This means you’re more likely to catch issues caused by material imperfections, environmental conditions, and other real-world factors.
