High Quality Through High Tech
Upon request, Apple Rubber can customize a quality program to meet your specific testing requirements. AppleLab® has some of the most sophisticated testing equipment and systems available today. Systems used in our custom testing procedures include:
- Mitutoyo® Quick Vision Measuring System - This non-contact measuring equipment uses the latest optical, video and image processing technologies to accurately measure parts without distortion. Measures even the most demanding microminiature parts quickly and accurately and provides statistical process control data.
- FTIR (Fourier Transform Infrared Spectrophotometer) - Determines chemical make-up of rubber compounds both before and after molding, in a matter of minutes. This ensures the consistency of rubber compounds and seals batch to batch, shipment to shipment.
- Thermogravimetric Analyzer (TGA) - Accurately determines the relative chemical content of materials and their thermal stability at temperatures up to 1,000°C. Completely computer controlled, the TGA delivers unequaled accuracy for material analysis.
- ASTM D1171 - Ozone Testing
AppleLab® features a wide variety of other specialized equipment to perform a range of tests on seals such as:
- Tensile strength
