In die-cutting industries such as electronics, self-adhesive, and precision materials, mirror spring holes, as the core components for precise punching and automatic waste discharge, directly determine the quality of product punching, mold life, and production efficiency. In the face of a variety of apertures, heights, steps and cutting edge specifications on the market, how to scientifically match their own product characteristics has become the focus of attention of many enterprises.

Recently, the core consumables in the field of precision die-cutting, mirror spring holes (also known as mirror punching, beer holes), are becoming a key support for high-end manufacturing in electronics, printing and packaging, automobiles, medical and other industries with the characteristics of no burrs, high roundness and strong adaptation.

With the upgrading of industrial manufacturing to precision and high reliability, as a basic process structure with both tight fixed position and elastic buffer function, the screw spring hole series has been deeply integrated into aerospace, automobile manufacturing, mold equipment, electronic equipment and other fields. Through the synergy of screw fixation and spring elastic reset, it solves the core needs of stable connection, anti-vibration and anti-loosening, and precise positioning under different working conditions, and has become an indispensable key structure in industrial assembly.

Recently, with the improvement of precision and stability requirements in the mold manufacturing industry such as stamping and die-cutting, the solid rubber elastic hole series (sleeve structure, special for screws) as the core elastic component has attracted widespread attention from the industry. In addition to the hardness parameters that are usually concerned, multiple factors such as size adaptation, material characteristics, and working condition adaptation directly affect the operating efficiency and service life of the mold, which has become a key link in the selection process.

The side cleaning hole (edge cutting hole) is a circular punching hardware installed on the die-cutting cutter template, and its core function is to automatically discharge the round waste through the side bevel structure during stamping/die-cutting. Its application scenarios are concentrated in industries that require high-speed, efficient, and high-quality punching, such as printing and packaging, labels, plastic films, and precision electronics.

In the context of the continuous improvement of machining accuracy and stability requirements in the precision manufacturing industry, the mirror spring hole series is widely used in die-cutting and stamping processes in electronics, automobiles, packaging and other fields with its core advantages of high finish and high sharpness. How to choose the right mirror spring hole products according to your own production needs has become a key link to improve production efficiency and ensure product quality. Industry experts combined product characteristics and application practices to sort out four core selection dimensions to provide scientific reference for enterprises.
