A plastic welt cord is a strong and round strip. It is used in bags and furniture. It helps things look nice and stay in shape. The cord goes inside the edges of seats, pillows, bags, or covers. Sunmolin is a factory that makes this kind of cord. The cords they make are clean, smooth, and strong. People use them in many things at home, in shops, or for fashion.
What Plastic Welt Cord Is
A welt cord looks like a long rope. But it is not soft like yarn. It is made of plastic, so it stays firm. Some cords are thin, and some are thick. They can be made in many colors. The cord gets covered in cloth or fake leather. Then it is sewn into bags or seats. People use it to make the sides look nice. The cord gives a round shape to the edge. It also helps the edge stay strong. If someone pulls the seat or bag, the cord helps hold it together. It makes the thing last longer and looks neat.
How the Cord Is Made
At Sunmolin, the plastic goes into a long machine. This machine heats it until it melts. Then the melted plastic is pushed through a small round hole. This shapes it like a cord. As the cord comes out, it goes through water. The water cools the cord, so it becomes hard again. The machine keeps pulling the cord, so it does not stop. At the end, the cord is cut into long pieces or rolled up. The workers check each cord. They look for a smooth shape, the right size, and no dirt. If a cord is not right, they do not use it. Only good cords go to the next step.
Making the Cord in Many Sizes
Some bags are small, and some seats are big. So the cord must be made in different sizes. Sunmolin has machines that can make thin cords or thick cords. Some are round like a pencil. Others are flat on one side. Each size has its own use. A small purse may need a very thin cord. A car seat needs a thick one. Sunmolin helps match the right size to the job. They can also make special shapes if needed.
Adding Color to the Cord
Plastic welt cord does not have to stay clear or white. Sunmolin can add color during the making process. This way, the cord looks bright and matches the fabric. Red, blue, black, and green are common. Sometimes, the cord is covered in fabric. Other times, it is left plain. If it will be seen in the final product, it must look nice. Sunmolin makes sure the color is even and clean. The color stays on and does not fade fast.
Why the Cord Must Be Strong
When someone sits on a chair, they press down hard. When a bag is full, it becomes heavy. The welt cord inside must hold up. If it breaks, the item looks bad or even breaks apart. That is why Sunmolin makes sure each cord is strong. They test the cord by bending and pulling it. It must not snap or tear. Even after many uses, the cord must stay firm. This helps bags and furniture last longer.
Safe and Clean Production
At Sunmolin, the factory is kept clean. The plastic used is safe. It does not have bad smells or things that can hurt people. The machines are checked often. Workers wear gloves and keep things tidy. The factory also makes sure not to waste too much. If some plastic is not used, they save it and use it again later. This helps the Earth by not throwing things away.
