Product Overview
High-Frequency Response for Fast Cycles
Our Injection Mold Spring is designed for the injection molding industry. It focuses on high-frequency response and long-term stability in fast injection cycles. Injection molds open and close many times per minute. Our product delivers consistent performance at this pace. It uses premium heat-resistant alloy steel formed through precision cold coiling and strict heat treatment. Every product stays stable, resists deformation, and avoids breakage over long-term use. Our 28 years of experience ensure we get this right.
Trusted by Industry Leaders Worldwide
Our factory has a modern 1,500-square-meter workshop and a team of 23 professionals. Every injection mold spring goes through raw material checks, in-process inspections, and final testing. Our market share exceeds 85% in the printing industry and 75% in die-cutting. Our customers include Mitsubishi, Tianjin Changrong, Guowang Group, and Huawei. These companies choose our product not for the low price, but for stability and reliability. Equipment downtime is a risk they cannot afford, and neither can we. That is why we maintain strict quality standards.
