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 the fact that many of them are polished even if the wire diameter is thin. Additionally, they are 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 sequentially transitioning to right-handed winding. Please understand that there are both left-handed and right-handed items available. 【Features】 ■ Standard springs designed for press machines using round wire ■ Selection based on deflection is possible ■ Many are polished even if the wire diameter is thin ■ Manufactured using high-durability SWPB (piano wire type B) *For more details, please feel free to contact us.

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 loads, medium loads, heavy loads, extra heavy loads, ultra 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 be used. *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 shape can be either an open end with no winding or a closed end with a seat winding to make the end face flat. Generally, the end face is ground flat to prevent load bias and damage to the mating parts. For springs with a small wire diameter (thin wire), grinding may be omitted as they have less impact on load bias and the 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 bias and damage to mating parts *For more details, please refer to the PDF document or feel free to contact us.
