Quality Control System:
1. Quality control at procurement of raw materials
When receiving the same raw materials from factory, we will examine the components of raw materials and compare it. If raw materials are the same with before, we will use it, otherwise, these raw materials will be refused.
2. Quality control at hot press process
As for hot pressing process, setting a flow card is a daily work. This process is strictly supervised by the flow card like the temperature of hot pressing process, how long the hot pressing process is for different products, who makes the semi-finished products into hot pressing process, each detail shall be wrote into this flow card, as for the workers who operate into the next process, it is clear to know that when this product is made and how long it is made.
Besides, when hot processing process, we start to do the first self-quality inspection process, as different products have different the temperature for hot processing process, even if the same products into the different layers of the hot pressing machines have a possibility that the same colors for semi-finished products is different, thus, once the same colors into the hot pressing process have color difference, all of the production for this color will be quit immediately and find the reasons why this color have this problem, when this problem is solved smoothly, the production for this color into hot pressing process will be re-started again.
3. Quality control at UV and annealing process
UV and annealing process supervised by flow card, into this flow card, the details like the date of annealing products, the temperature of outlet of annealing line and what the annealing speed is, all of vinyl flooring shall be put into constant temperature room at least 48 hours after annealing.
4. Quality control at punching process
From punching process, we start to do the second process for self-inspection, when some products have some quality problems like each layer of semi-finished products is separated and the dirt onto the surface of semi-finished products during punching process, all of these products will be selected and then be disposal into the smash machines.
5. Quality control at clicking system
we start to do the third process for self-inspection, some points like squareness, straightness and gap between two pieces of click products when jointing. Thus, we have professional test machines like mould of squareness, straightness, the mould of different click system, these mould are constantly used into making click system to 100% guarantee that all of click products will be as perfect as possible.
6. Quality control at packing process
finally, into the packing process. We start to do the forth process for self-inspection. When packing of finished products, some points like colour difference for the same colors and crash of click products, regarding the products that have these problems, all will be selected and be disposal. Besides, even though there is the dust adhering to the finished products into the making click system process, this dust will be wiped and cleaned.
