BLOG/ Manufacturing Process: How Quality Doors are Made

Follow our Manufacturing Process

Quality control is an important part of the manufacturing process at Eight Doors. Establishing a standard is essential so that everything can be produced safely at its highest quality.

Having standards in place ensures that the desirable characteristics (quality, safety, reliability, efficiency, interchangeability, and environmental responsibility) of our doors are all available at an economic cost to our customers.

When buying a product with quality control in place,  you have an immediate confirmation of the quality, efficiency and safety of that product.

In order to identify the importance of quality control, we will present some of the tests that are performed on our products. It is amazing how much is done to a door before it is worthy of being shipped to your home. The diversity of tests done is truly incredible!  

What are the evaluated characteristics of the products?

Without going too deep into technical terms, we will specify some of the requirements in the evaluation of a door’s performance profile and the respective classification of wooden doors for buildings according to the level of performance, occupancy and use.

• Dimensions and Tolerances
• Visual aspects
• Product identification standards
• Product construction standards
• Definition of specific requirements: humidity, temperature, acoustic protection, warping and others.
• Product performance standards

• Vertical loading
• Static twist
• Soft body impacts
• Hard body impacts 
• Resistance to closure with presence of obstruction
• Resistance to horizontal stress, in the plane of the slab, with two immobilized corners
• Flexural strength
• Resistance to abrupt closing
• Opening and closing cycles
• Usage traffic
• Leaf opening and closing force
• Action applied on the doorknob
• Action applied on keys
• Resistance under presence of water, heat and humidity.

There are more tests than you could ever imagine! Another point worth mentioning in this quality control, is the number of times the doors are subjected to the opening and closing cycles tests.

The doors are not just opened or closed a couple of times, we test them more than 20,000 times! 

In order to really test the quality, efficiency and safety of each door produced, all of the tests done with the doors are subjected to extreme repetition. We do this to provide you with a door that will withstand the daily wear and tear of life for many years to come! This is an essential part of our manufacturing process, because we care about the longevity of our doors. 

CARB II Compliance

California Air Resources Board (CARB) II is a stringent emission standard for formaldehyde emissions from composite wood products, including HWPW, PB, and MDF. Formaldehyde is a toxic organic compound that is essential in many wood products. It is most often used to make adhesive resins in composite wood products. Formaldehyde is harmless in small amounts (it is even naturally present in the human body) and is probably already in most of the wooden fixtures in your home.

Formaldehyde is only problematic when found in high concentrations. The only way to ensure the wooden products in your home won’t saturate the air with formaldehyde is to make sure the product is CARB II compliant. All of EightDoor’s products are CARB II compliant and do not emit any compounds that could be toxic to your family. 

Sustainability

Our doors are manufactured with certified wood, meaning we don’t use wood from;

• Areas where civil and traditional rights have been infringed;

• Forests with high conservation value;

• Genetically modified forests;

• Illegally exploited forest areas;

• Areas in which the native forest is converted into plantations.

All of our wood comes from renewable tree farms. When trees are cut down, new trees are planted in their place. We are proud to say that we do not support unethical environmental and social practices when we source our materials. High quality products must come from high quality sources that takes the longevity of the environment into consideration. We feel good about the origin of our materials, so you can rest assured that you are getting the best door for you and yours.

Our manufacturing process is uniquely sustainable, the wood scraps that are not used in our doors are used to make energy to power our factory. This creates a sustainable energy cycle that we are very proud of! 

Customer and business benefits

For customers, these tests and certifications offer the advantage of obtaining high quality products, ease in business relations, greater customer satisfaction and peace of mind. We guarantee a high quality door that is built to withstand the test of time.

Quality control counts with inspection from start to finish

To ensure that the entire process is performed to our high standards, inspections are carried out when the materials arrive in the warehouse and during the entire manufacturing process. Of course, we perform a final inspection of the products before they are sold and shipped out.

Until the moment our doors reach you, many tests are done to guarantee  quality, safety and efficiency.
