Introduction Manufacturing

In 1990, Hi-Tech Seals was founded in Edmonton, Alberta. We have since expanded to six locations across Canada and one location in the United States. A major factor in our success has been our ability to supply quality products, delivered on time, at a competitive cost, backed by a knowledgeable team of sealing professionals. As an international seal and gasket company, Hi-Tech Seals utilizes in‒house and global engineering and manufacturing resources. This allows our technical sales team to work with various individuals to find a superior solution for any sealing or gasket application.

IntroductionWe are committed to our Quality Management System (QMS). Hi-Tech Seals registered our first branch under an ISO QMS in 1996. Now, all our locations and divisions are registered under the ISO QMS. The four main goals of our policy include:

• Hi-Tech Seals shall distribute and/or manufacture a quality product that will meet our customers requirements and expectations.

• Hi-Tech Seals shall strive to continually improve the effectiveness of the Quality Management System.

• Hi-Tech Seals' Quality Policy shall be communicated and understood at all levels of the organization.

• Hi-Tech Seals' Quality Policy and Quality Objectives will be reviewed for effectiveness and accuracy during the Annual Management Review.

ISO 9001 Registered QMS

Custom seal kits provide customers with an easy to use system of reordering groups of product. Whether it is for a piece of machinery that undergoes maintenance or for manufacturing machinery, our sales staff will identify the sealing components and create a kit in our system. The kit can include custom labels with company logos and part numbers. When placing an order, simply provide us with the kit number and receive the parts in one bag.

Custom Seal Kits

Hi-Tech Seals offers an on‒call service available after regular business hours, including weekends. An after-hours sales representative can be reached by contacting a local Hi-Tech Seals branch. Service charges may apply.

ManufacturingRapid Gasket

LaserQC®Hi-Tech Seals Gasket Division employs a Virtek LaserQC® 1200 machine. The LaserQC® assists in reverse engineering, quality inspection and control, and statistical process control. It captures over 500 data points per second, while maintaining a tolerance within ± 0.05mm (0.002"). Our drafting department makes adjustments to the scanned data to optimize the tolerance levels. The file can then be exported directly to our flashcutters or water jet for rapid gasket production.

FlashcutterOur two Atom Flashcutters are capable of utilizing CAD renderings to quickly produce gaskets from rubber, plastic and composite materials. Each flashcutter’s surface area can accommodate material up to 60" × 120". We are capable of cutting rubber materials up to 1" thick and plastic and composite materials up to a 1/2" thick.

The flashcutters use a rapid vertical reciprocating motion to cut the gaskets. The cutting motion produces a cleaner finished part, avoiding compression marks found on die‒cut gaskets. The flashcutters' vacuum surfaces hold sheet material in place preventing the movement of parts during production. This enables the flashcutter to maintain exceptional tolerances.

Equipment

Waterjet

Die Cut

The Omax waterjet further expands our manufacturing capabilities. The waterjet cuts the standard composite and rubber materials, but also allows us to manufacture metal gaskets up to 6" thick. The waterjet working surface area is 60" × 135".

Hi-Tech Seals Gasket Division utilizes a clicker press to produce die cut gaskets. Dies are manufactured locally and stored in house. Our die cutting capabilities include all soft gasket materials in various shapes.

Hand CutFor cost effective small runs, our Gasket Division produces hand cut gaskets. Hand cut gaskets are excellent for prototype applications or for one of a kind parts.
