Compared to general round wire springs, by using silicone chrome steel wire, which excels in fatigue resistance and deformation resistance, in deformed wire springs (square wire springs), it is possible to generate strong force in a small space. Although designed for molds, they are also used in heavy machinery, elevators, and other mechanical parts. There are standards for light small loads, light loads, medium loads, heavy loads, extra heavy loads, super heavy loads, and high deflection, and they are color-coded by type for easy selection. When choosing DAIspring, please decide on the four points of load, spring outer diameter, number of uses, and deflection to select the appropriate option. *For more details, please refer to the PDF materials or feel free to contact us.

The "compression coil spring" is referred to as a "compression spring" and is a spring that receives load at the center of the coil. The end face shapes include open ends that are left coiled and closed ends that have a flat end face due to a seat coil. Generally, the end faces are ground to make them flat to prevent load imbalance and damage to mating parts. For those with a small wire diameter (thin wire), grinding may be omitted as they have less impact on load imbalance and mating parts. 【Features】 ■ Made of stainless steel ■ A spring that receives load at the center of the coil ■ Available in open end and closed end ■ Prevents load imbalance and damage to mating parts *For more details, please refer to the PDF document or feel free to contact us.

We sell standard springs "TRYspring" and square wire strong springs "DAIspring." The "molded round wire coil spring" of DAIspring is a standard spring designed for press machines, allowing for selection based on deflection, unlike conventional round wire standard springs (TRYspring). It is characterized by many fine wire diameters being polished. Additionally, it is manufactured using high-durability SWPB (piano wire type B). We are currently producing them sequentially, so please inquire about delivery times. <Apology> Due to production circumstances, we are gradually transitioning to right-hand winding. Please understand that there are both left-hand and right-hand options available. 【Features】 ■ Standard springs designed for press machines with round wire ■ Selection based on deflection is possible ■ Many fine wire diameters are polished ■ Manufactured using high-durability SWPB (piano wire type B) *For more details, please feel free to contact us.
