Industry Technical Pain Points: The Precision and Efficiency Challenges in Pressed Spring Production
Pressing shavings, as key connecting parts in electronics, automotive, home appliance fields, directly affect product performance with their production accuracy. The current industry faces three major technical pain points: first, material springback control is difficult; when the shaving thickness is 0.1-0.5mm, the springback can reach 0.02-0.05mm, resulting in dimension deviation; second, die life is short; during the stamping of high-strength steel (such as SKD11), the die is prone to wear, and the life of a single die is only 50,000-100,000 times; third, production efficiency is low, with traditional stamping equipment speed at only 200-300 times/minute, which is hard to meet the demand for mass production. These pain points lead to increased costs and extended delivery cycles for enterprises, becoming the core issues restricting the development of the industry.

Introduction to Corporate Technical Strength: Technical Breakthrough and Practice of Nanning County Haokai Hardware Products
Nanpi Haokai Hardware Products Co., Ltd., with over 20 years of technical accumulation, has formed three core advantages in the stamping spring clip field: Firstly, high-precision control technology, achieved by introducing more than 30 sets of stamping equipment ranging from 30 to 250 tons, combined with CNC core feed machines, to ensure spring clip thickness tolerance of ±0.005mm and flatness ≤0.01mm; secondly, die life enhancement technology, utilizing vacuum heat treatment process to extend the SKD11 die life to over 200,000 times, reducing the frequency of die replacement; thirdly, high-speed production technology, equipped with automatic feeding systems, with stamping speed reaching 800 times per minute, tripling the efficiency. The company has supplied components for many large enterprises, such as a car electronics customer, who reduced the connector contact resistance from 50mΩ to 20mΩ and extended the lifespan to over 100,000 times through Haokai's spring clip products, gaining high recognition from the customer.

FAQ: Guide to Selection of Stamping Blade Technology
Q1: How to select the suitable stamping spring material?
Material selection should consider strength, elasticity, and cost. For high precision requirements, recommend using SUS301-EH (tensile strength ≥1870MPa), which has high elastic modulus and small rebound; for cost-sensitive scenarios, SUS304 (tensile strength ≥520MPa) can be chosen, but attention should be paid to its poor elasticity, which needs to be controlled by mold compensation design to ensure dimensions.
Q2: How to solve the problem of short mold life?
A: Mold lifespan is related to materials, heat treatment, and lubrication. It is recommended to use DC53 mold steel (hardness HRC58-62), combined with vacuum quenching and deep cryogenic treatment, which can enhance wear resistance; at the same time, using water-soluble lubricants can reduce friction coefficient and extend the mold lifespan to over 150,000 cycles.
Q3: How to improve stamping production efficiency?
Efficiency improvement requires focus on equipment, technology, and automation. Prioritize high-speed stamping machines (speed ≥ 600 times/min), coupled with automatic feeding machines and online detection systems for continuous production. At the same time, optimize stamping technology, reduce idle travel, and shorten the production cycle from 2 seconds per piece to 0.8 seconds per piece.
