Test-Centric Assembly for Leak & Functional Testing Systems
InterTech’s Test-Centric Expertise and Uptime Optimization Services

Test-Centric Assembly Expertise and Sample Part Range
InterTech coined the phrase “test-centric assembly” to describe the upfront consideration of real-world test requirements in test-intensive assembly and test operations that is proven to lower production line inefficiencies. Test-Centric Assembly is a best-practice approach for any test-intensive assembly operation. A common, but far less satisfactory approach to machine building of test-intensive assemblies is to consider leak detection testing, functional testing, or another testing as an afterthought to overall machine design.
InterTech’s Test-Centric Assembly Advantage for Superior Assembly and Test is based on:
- Detailed Understanding of Leak Test and Functional Test Requirements
- Standard Line of Test-Centric Chassis and Modules
- Extensive Test Fixture Design Knowledge Base for leak testing, hydraulic testing, and functional testing
- Customized Real-Time Monitoring Software and Remote Diagnostics
- Expert Network Integration
- Flexible, User-Friendly, and Easy-to-Maintain Processes
Uptime Optimization Consulting Services
Machine builders, automotive component manufacturers, and others seeking faster test-intensive assembly operations can access InterTech’s Uptime Optimization consulting services that detail how to incorporate online calibration and validation of test technology, automation of temperature compensation during testing, and similar engineering that minimizes or eliminates previous needs to shut down test-centric assemblies for recalibrations. InterTech engineers estimate that a combination of solid-state capabilities for online recalibrations can eliminate up to 60 minutes of assembly downtime in each 8-hour shift using machines with leak testing stations. Many assembly operations are straddled with mechanical type calibration and validation processes that are now obsolete. Machine builders that are adding test technology as a secondary consideration in a larger assembly often do not know that they are using substandard leak testing technology that slows down production processes. One of the more straightforward ways to optimize production uptime is by adding electronically self-calibrating leak testers that automatically validate entire test systems while they are in operation.
Another method is by using technology that can automatically adjust testing and interpret results correctly for parts testing at different temperatures, such that cooling of recently cast parts isn’t necessary. These are some of the ways in which InterTech Development Company can help machine builders and assemblers re-engineer processes to eliminate downtime.
