At Dynamic Closures, we know that any delays in your schedule can be costly. That’s why we’ve developed one of the most thorough quality assurance processes of any commercial security door manufacturer.
When new components, mechanisms, or door materials are developed each one is tested both individually and in concert with the other parts of the assembly. From initial design through prototyping through user testing, we find that the creativity of our solutions is only matched by the creativity of our testing process.
Here’s why you can have total confidence that when your new door arrives at your building site, it will be exactly what was promised.
1. Digital Design and Testing
When our new parts or mechanisms are designed, they are examined from all angles by our Production Engineering Manager, Mike Svenson, and key members of his team. Models of new components are checked against models of all the other components they will be in in contact with. Measurements are confirmed and any initial problems eliminated.
2. Testing for Fit Using 3D Rapid Prototyping
Once the digital models look good, they are sent to our 3D printer. An inexpensive plastic prototype can be created in a matter of hours.
With the full scale model of the part in hand, we can confirm the fit against the other parts in the assembly. If any unforeseen issues are found, the model is adjusted and a new prototype created.
We adopted 3D prototyping in 2012, and since then it has saved us thousands of dollars in costs and time. We can make design adjustments faster and more cheaply than ever, allowing us to offer new products for less than we could have before we had this technology. Learn more about our use of 3D rapid prototyping and how it benefits our clients.
3. Testing for Longevity
Once the new component has a confirmed fit, a working version is machined using the final material, usually stainless steel or high-grade aluminum, depending on customer specifications.
The working parts are assembled and then tested for long-term durability. Since most security doors are opened once in the morning and closed at night, we can simulate 20 years or more of use in days with a rapid-cycle testing machine that moves the working parts over and over again hundreds of times an hour. We generally subject new assemblies to 10,000 to 100,000 cycles, depending on the extent of the change to the design. When required, we test using different materials to find out which ones work best.
With this system, the parts are exposed to additional friction and heat than it would experience in the real world, which means the final product lifespan should exceed our results.
4. Testing for Ease of Operation/Usability
While robotic equipment is great for repetitive testing, no robot can equal the unpredictability of usage by actual human beings. That’s why we set up complete door systems at a testing station for use by a variety of people. This allows us to discover if there are any difficulties in using the new door.
Because end users of our doors are often women, we test with women. Retail staff often wear high heels and may not have the same ability to balance, so we want to make our products as easy to use as possible.
Our tests confirm that:
- Doors move smoothly when manipulated by people of various heights.
- Door sway doesn’t cause sticking in the track.
- It doesn’t take a lot of physical strength to move the doors.
- Locking mechanisms are within reach of shorter people or wheelchair users.
- Locking mechanisms are easy to operate for people with less hand strength.
Creativity in testing design is the key to ensuring our doors are ready for the unpredictable ways that people will try to use them.
5. Testing to Failure
All of our designs and materials have been tested to failure so we know how creative architects can get with our designs. We are aware of parameters like how much weight hangers can carry, and how much force it takes to pull apart our hinges. This is a huge help when we get requests for custom designs.
For example, Holt Renfrew needed a side folding door that was 25 feet tall. Because taller doors mean additional weight, we knew we would need to create the hangers and related fittings out of an extra strong steel. We also knew the locking bolt would end up being much taller, and therefore heavier. To compensate, we used a lighter material to ensure staff would have no trouble operating the lock.
6. Testing Every Individual Door for Perfect Fit
We assemble, measure, and operate every single door we build – not just the initial designs. Our QA team signs off on every product that leaves our manufacturing facility, confirming it meets your original specifications exactly.
Guaranteed Sizing and Function
At Dynamic Closures, we know that architects and designers are often faced with challenging requirements and deadlines. We strive to do everything possible to adapt to your needs, and guarantee that our doors will meet your specifications and will be as user-friendly as a security door can be.
We also provide some excellent resources to help you develop your specifications correctly. You can save time with our extensive library of 2D and 3D CAD files. We also have an online specifications generator called EasySpec. Feel free to contact our support team if you have any requirements you need to discuss.
