Getting the right hinge for your commercial or industrial product relies on having a trusted and reliable hinge manufacturer. Enter cellular manufacturing. 

No matter where you live, work, or play, there are hinges around. Cabinets, fridges, grills, cars, and airplanes all have hinges that we interact with on the day-to-day. 

Boats in particular offer an interesting opportunity for implementing kinematic motion control, mechanical spring counterbalance, and spring assist technologies. Marine hinge design takes into account factors ordinary hinge design might not, including weather condition, humidity, and corrosion. 

As a kid, you might have marveled at the flip-up bar countertop at your parents’ favorite restaurant. But a lot has changed since then, and bar lift gates have improved significantly. 

Lift assists for bar and countertop openings are crucial in modern taverns, kitchens, and restaurants. While they add aesthetic appeal, their main value lies in functionality.

Today’s hinges make life much easier and more comfortable. We have progressed so far from just a plain, 'ol door hinge to advanced solutions for kinematic motion, mechanical spring counterbalance, and spring assist technologies. 

Customer expectations can certainly change in a 112-year span.

Do your employees spend a lot of time at their computers? At this point, who doesn’t?

When people think of the term engineering, things like rockets or skyscrapers come to mind. But not all engineering is about building massive structures or traveling into space. 

Some engineers focus on the little details that take a customer’s product from ho-hum to high-end.

We spoke with Erik Dahlgren, the Director of Manufacturing Engineering at Weber Knapp, to find out how those little details can be a game-changer for a customer’s product.

The Vectis™ team traveled to Atlanta, GA to attend the 2017 Hearth, Patio, & Barbecue Associations HPBExpo – North America’s largest indoor-outdoor living showcase.

So, you’ve decided that a springloaded counterbalance hinge is the ideal way to take your project to the next level. And, you already know that a Vectis™ Counterbalance Hinge can address your specific design challenges and that a Vectis™ counterbalance hinge will outperform and out last a gas spring. But, what technical considerations do you need to make before you click the DYO tab?


To help prepare you for your visit to the DYO app, over the next several months we’ll be discussing some of the technical decisions you’ll need to make in order to design the perfect counterbalance for your project. This month we’re going to discuss the effects of vertical distance to the center of gravity and what that could mean in regard to the ultimate function of your project.


The vertical distance to the center of gravity can have a big impact on how your lid acts near the open position. The greater the positive vertical distance the greater the tendency for the lid to self-open at larger open angles. Conversely, a negative vertical distance allows the lid to be potentially counterbalanced up to the maximum 90° opening angle. If you do not want the lid to coast open at larger angles, consider reducing the maximum opening angle to something close to the balance angle of the lid. The balance angle is the angle of the lid at which the center of gravity is directly above the pivot. If you are looking at the torque chart on the Vectis® DYO app, the balance angle is the point where the lid torque drops to zero.


For applications where the vertical distance to the center of gravity is sizeable, a large opening angle is required, and minimal coast towards the full open position is desired, rest assured that we can meet your needs with a Vectis® Counterbalance Hinge or a Vectis™ Custom Counterbalance.
