Automated Inspection and Packaging Systems

Fast and accurate. Two adjectives you want to use to describe the inspection process. That’s exactly what you get with North Coast Seal’s automated o-ring and molded rubber part inspection process. No matter the industry, be it natural gas, aerospace or automotive, if inspecting rubber products specs is vital to your project, NCS is the team to trust.

Inspection Technology

North Coast Seal has cutting edge equipment and technology that ensures that our inspection process is the most accurate and expedient in the industry. Take a look at some of the items we use to deliver quality inspections with fast turnaround:

FTIR Comparison Machine

Analyzes material and directly compares it to the customer’s approved sample, rating it on a 100 point scale with 93 points being considered a match. The process is done automatically and not subject to any operator input. This machine calibrates itself every cycle.

Specific Gravity

Electronic scale that measures weight in air and water. This procedure verifies that we have the correct base material.

Compression Set

This oven is calibrated to perform compression set testing which requires heating controlled within +/- 1°. Results of the test tell us that the product being tested has been properly cured or baked during the manufacturing process.


This is tested on all incoming parts per customers’ specifications. The number derived from this test tells us the hardness of the material. This is expressed numerically using an industry adopted scale which was developed by the Shore Manufacturing Company.


Hector the Inspector is an automatic sorting system composed of two tables which enable the pieces to be checked on both sides. They are loaded in bulk and then separated in different bins, into good parts and scraps, at the end of each inspection cycle. The operator sets the machine with the parameters and the tolerances required and as a result, he obtains a complete report of the good parts. The machine guarantees a perfect repeatability of the checks and traceability of the inspected batches.

Hector also has an automated packaging system that will bag your parts immediately after inspection using pneumatic motion for sealing capabilities.

Molly is a sophisticated measuring machine that collects sample data of all our incoming and outgoing products. This data consists of dimensions on the plane and thickness. Its camera’s telecentric lens acquires the image without distortion on the 2D plane and it measures in inches and millimeters. It gives us the measurements within seconds, ensuring accuracy and repeatability each and every time. Its large telecentric lens is one of the keys to our success ensuring pin point accuracy.

This innovative instrument is able to simplify the measurements and the aspects controls during the entire inspection process which ensures our quality standards are above average. We can measure different shapes, sizes and dimensions utilizing this 2D/3D state-of-the-art technology.
