HOW DOES DOORWIN MAKE GOOD WINDOWS?

When we are talking about window production process, we are talking about some detailed matters about the window manufacturers. It could be divided to three main aspects: raw materials, manufacturing part, quality assurance system. Taking wood aluminum tilt-turn window as example, let’s see how does Doorwin make good windows.

RAW MATERIALS: Wood aluminum tilt turn window is a window style originated in Europe and popular in modern homes, featuring solid wood interior and aluminum exterior cladding in materials as well as dual functions that swing like a door and opens from the top like hoppers. For materials, solid wood is available in popular species like pine, oak, teak, also available in hem, mahogany, alder, walnut, etc. Finger joint wood technique is applied to allow for better intensity. For exterior aluminum, we use the finest extruded aluminum with the thickness of 1.4 mm to 1.6 mm, which is much thicker and stronger than many of the companies. Color options are all available in over 200 RAL classic colors. Our Seamlessly Welded Joint technique gets the miter joints welded and ground smooth for additional strength, protection and improved aesthetics. For hardware, we applied Germany originally made brand ROTO/ SIEGENIA, which is a well-known for its multi- point lock for high security and longevity. As for glazing, all of the our glass are fully tempered glasses, which uniformly shatters into small pieces for safety. Double glazing is our standard options and triple glazing, low-e coating, argon gas filled is available for higher performance demand. (Find out more about it, visit www.doorwingroup.org) 

MANUFACTURING PART: After we select excellent materials, the next step is to manufacture. From beginning to ending, experienced workers are working hard and responsible at every part of every product. Each part of the windows can be tracked if anything doesn’t goes right. For every step of, there is one separate zone. With the support of advanced machines, zones connect closely to the front and back one to form our great manufacturing networks.

QUALITY ASSURE SYSTEM: Doorwin has its own systematic quality assure system.We applied 5 main point checking system. Firstly, we will build one Small professional team, and choose 8 most experienced workers to cut & assemble all windows &doors. Then select 2 quality inspectors to control the quality and performance from the beginning to end. Secondly, when all aluminum/ wood profiles arrive at our factory, our quality control inspectors will check all of them one by one, that way, we can make sure all finishing are with good quality. Thirdly, when our workers cut and assemble the wood/ aluminum frames, scratch and damages are not allowed to happen. Fourthly, after the assembling is finished, quality control inspector will check the joints of wood/ window frames to make sure all joints are smooth. Fifthly, when all windows & doors are completed, we will test all windows and doors to see whether they function well. If there is any item that can not work well, we will adjust the hardware and accessories until they work well.
