Rectangular springs are made of square wire material. Rectangular springs are also known as die springs because the cross-section of the material used to make them is rectangular, so they are called rectangular springs. Ordinary springs are made of round wire. Rectangular springs are much stronger than ordinary springs and have better fatigue resistance than ordinary springs.

Precision Springs
　　Introduction of Rectangular Springs

　　Rectangular springs are generally made of alloy. High-quality chrome alloy steel material mold spring products have the maximum load-bearing capacity and lengthen the service life of the material used in the United Springs SV9254 chrome-silicon alloy of the rectangular steel wire, ground flat.

　　Classification and characteristics of rectangular springs

　　Rectangular spring load rating is usually distinguished by color, the color can reflect the compression of the compression spring as well as the size of the elastic force. Common colors of rectangular springs are purple, yellow, blue, red, green, brown, orange, ivory, light blue, light green. They are small in size, can withstand high speed amplitudes, and have good stability and fatigue strength.

　　Rectangular Section Compression Springs: Similar in nature to the round interface cylindrical coil spring, the difference lies in the rectangular cross-section of the material used. Under the same spatial conditions, rectangular section helical compression springs have higher stiffness.

　　Application advantages of rectangular springs

　　Rectangular elasticity is in addition to nitrogen gas springs, to provide elasticity for the mold commonly used parts. The size of the spring force is related to whether the mold production is smooth, whether the hit out of the product is qualified and so on. If the spring strength is small, it may cause various problems such as product deformation, molds do not release material, products are not good to be taken out from inside the molds, carry material, and the cutter and punch are easy to wear out. Compared with ordinary springs, rectangular springs use square wire, with better strength and fatigue resistance. To a certain extent, it can reduce the production risk brought about by the use of poor-quality springs, improve production efficiency and save production costs.

　　Rectangular springs are widely used in stamping molds, metal die-casting molds, plastic molds and other elastic motion precision machinery and equipment, automotive and other fields. The quality exceeds the customer's requirements, greatly reducing the customer due to the use of poor quality springs brought.
