Spring Specifications
Understanding spring specifications is essential for selecting the right component for your application, whether it's for custom plastic injection molding or other industrial uses. Our comprehensive specification system ensures that you can accurately select springs that meet your exact requirements, ensuring optimal performance and reliability.
Spring specifications encompass several key parameters, including wire diameter, outer diameter, free length, number of coils, material type, and load characteristics. Each of these parameters plays a critical role in determining the spring's performance in specific applications, particularly in custom plastic injection molding where precision is paramount.
Wire diameter is one of the most fundamental specifications, directly influencing the spring's force output and load capacity. Larger diameter wires produce stiffer springs capable of handling higher loads, making them suitable for heavy-duty applications in custom plastic injection molding equipment. Our springs are available in a wide range of wire diameters to accommodate various load requirements.
The outer diameter of a spring determines the space requirements and compatibility with surrounding components. In custom plastic injection molding applications where space is often limited, selecting a spring with the appropriate outer diameter is crucial for proper fit and function. We offer springs in various diameters, including compact designs for space-constrained applications.
Free length specification refers to the spring's length when not under load, while solid height indicates the length when fully compressed. These dimensions are critical for ensuring proper installation and operation within your custom plastic injection molding equipment, as insufficient free length can result in inadequate deflection, while excessive length may cause interference with other components.
Load specifications, including initial tension, rate, and maximum safe load, define the spring's performance characteristics under various conditions. Understanding these specifications is essential for ensuring that the spring can handle the required loads in your custom plastic injection molding applications without exceeding its design limits, which could lead to premature failure.
Our technical documentation provides detailed specifications for all our springs, including performance charts and application guidelines specific to custom plastic injection molding applications.
