Sample Testing
regularly conduct prototype chair testing

At present, our team will regularly conduct prototype chair testing, or select samples from large shipments for testing to ensure that the chairs are of high quality and 100% safe for customers. If you or your customers attach great importance to the quality of chairs, you can also select samples from bulk products and use our laboratory for ANSI/BIFMA level testing.

The Key to Enhance Chairs' Quality

Base on many years international trade experience, Yumeya deeply understand the particularity international trade. How to reassure customers about quality will be the key point before cooperation. All Yumeya Chairs will undergo at least 4 departments, more than 10 times QC before packaged. 

Hardware Department
Wood Grain Department
Upholstery Department
Package Department
Raw materials shall be tested before entering the hardware department for deep processing. For aluminum tubing, we will check the thickness, hardness and surfac. Here are our standards.
In Yumeya's quality philosophy, standards are one of the four important factors. Therefore, after bending, we must detect the radian and angle of the parts to ensure the standard and unity of the finished frame. First, our development department will make a standard part. Then our workers will adjust according to this standard part through measurement and comparison, so as to ensure the standard and unity.
Due to the thermal expansion and cold contraction in the welding process, there will be slightly deformation for the welded frame. So we must add a special QC to ensure the symmetry of the whole chair after welding. In this process, our workers will adjust the frame mainly by measuring the diagonal and other data.
The final QC step in the hardware department is the sampling inspection of finished frame. In this step, we need to check the overall size of the frame, the welding joint is polished or not, the welding point is flat or not, the surface is smooth or not and etc. The chair frames can enter next department only after reaching 100% sampling qualified rate.

In this department, it needs to undergo three times QC, including raw materials, frame surface and finished product color matching and adhesion test.

As metal wood grain is a heat transfer technology which is composed of powder coat and wood grain paper. Little changes in the color of powder coat or wood grain paper will lead to color big change. Therefore, when it is newly purchased wood grain paper or powder, we will make a new sample and compare it with the standard color we sealed. Only 100% match can this raw material be considered qualified.
Doing surface treatment like the make-up in a face, first of all, must have a smooth face (frame). There may be collision of the frame during cleaning. So we will undergo fine polishing and check the frame after cleaning. Only the frame without any scratch then it will be fit for surface treatment.

As the whole wood grain production process involves many factors such as the thickness of powder coat layer, temperature and time, small change of any factor may lead to color deviation. Therefore, we will check 1% for color comparison after completing the wood grain finish to make sure it is the right color. At the same time, we will also conduct adhesion test, only none of the lattice powder coat falls off in the hundred lattice test can be accepted.

In this department, there are three times QC, QC for the raw materials of fabric and foam, mold Test and upholstery effect.

In the upholstery department, fabric and foam are two main raw material
● Fabric: The martindale of all Yumeya standard fabric is more than 80,000 ruts. So when we receive the new purchase fabric, we will test the martindale at the first time to make sure it is more than standard. At the same time, we will also test the color fastness to ensure it won't fade and suitable for commercial use. Combine the QC of color, wrinkles and etc these basic quality problem to ensure it is the right fabric.
● Foam: We will test the density of the new purchase foam. The density of the foam, it should be more than 60kg/m3 for mold foam and more than 45kg/m3 for cut foam. Besides, we will test the resilience and fire resistance and other parameter etc to make sure its long life time and suitable for commercial use.

Due to the differences in tensile force and thickness of different fabrics, we will make a sample using the order fabric before bulk goods to adjust the mold for cutting fabric to ensure that the fabric, foam and chair frame can perfectly match without wrinkles and other upholstery problems.
For a high-end chair, the first thing people see and feel is the upholstery effect. Therefore after upholstery, we must check the whole upholstery effect, such as whether the lines is straight, whether the fabric is smooth, whether the piping are firm, etc. To make sure our chairs meet the high end require.

In this step, we will check all parameters according to the customer's order, including size, surface treatment, fabrics, accessories, etc to make sure it is the ideal chair that the client order. At the same time, we will check whether the surface of the chair is scratched and clean one by one. Only when 100% of the goods pass the sampling inspection, this batch of large goods will be packed.

Since all the Yumeya chairs are used in commercial places, we will fully understand the importance of safety. Therefore, we will not only ensure the safety through the structure during development, but also select chairs from bulk order for strength test, so as to eliminate all potential safety problem in production. Yumeya is not the only metal wood grain chair manufacturer. Based on her special  and complete QC system, Yumeya will be the company that knows you best and reassures you most.
