Introduction
A heavy duty butt hinge is an essential component for connecting two pieces of materials together, and it must have the strength to support the weight of whatever it is connecting. Oil free butt hinges are a preferred choice for many applications due to their durability and rust-resistance, and they are especially popular for outdoor use. Laser welding technology has recently been implemented in the manufacturing of oil free heavy duty butt hinges, and this has drastically improved the quality and durability of the hinges.
Laser Welding
Laser welding is a process that uses a focused beam of high-energy light to fuse two pieces of metal together. This process is highly precise and ensures that the two pieces of metal are welded together with no gaps or air pockets. This technology is particularly useful for oil free heavy duty butt hinges since the welding process is stronger than traditional methods such as pressure riveting plugs, and it ensures that the hinge spindle will never fall off.
Seamless Steel Pipe
Another key component of oil free heavy duty butt hinges is the use of seamless steel pipe. This type of steel has a higher tensile strength than other types of steel, and it is more resistant to corrosion and wear. By using seamless steel pipe in the construction of oil free heavy duty butt hinges, manufacturers are able to ensure 100% concentricity, smooth opening and closing, and they are able to reject abnormal noise that could be caused by poor concentricity.
Testing
Finally, oil free heavy duty butt hinges must undergo rigorous testing to ensure that they meet the highest standards of durability and quality. Manufacturers typically conduct more than 300,000 times of opening and closing tests on their hinges to ensure that the hinges will not fail even under the heaviest loads.
Conclusion
Oil free heavy duty butt hinges are a great choice for many applications due to their durability and rust-resistance. The use of laser welding and seamless steel pipe in the construction of these hinges ensures that the hinges are of the highest quality and that they will last for many years. Furthermore, manufacturers conduct more than 300,000 times of opening and closing tests to ensure that their hinges will not fail under heavy loads. For these reasons, oil free heavy duty butt hinges are a great choice for any application.
