Introduction
In the hardware manufacturing industry, precision stamping parts serve as core components, with their processing accuracy directly influencing product performance and reliability. Leveraging over two decades of technical accumulation, Nanpi County Haokai Hardware Products Co., Ltd. has developed unique technological advantages in precision stamping by introducing advanced equipment and optimizing process flows. This article will analyze its technological layout and innovative practices from dimensions such as technical principles, equipment parameters, and practical cases.

Key words
Precision stamping parts; High-precision instrument turning parts; Stamping equipment; ISO9001 quality system; Optimization of technical parameters

Opening Remarks on Industry Technical Pain Points
There are three major pain points in traditional stamping processing:STEP 1: Insufficient accuracy- The tolerance range of ordinary stamping equipment reaches ±0.1mm, making it difficult to meet the requirements for high-precision instrument vehicle parts;STEP 2: Inefficiency- Single-process machining requires multiple clamping operations, with a production cycle exceeding 5 minutes per piece;STEP 3: Material Waste— Traditional mold design results in over 30% of offcuts, increasing production costs. A certain automotive parts enterprise once experienced a complete vehicle assembly failure due to precision deviations in stamped parts, incurring direct losses exceeding RMB 2 million, highlighting the urgency of technological upgrades.

Introduction to the company's technological strength
Nanpi Haokai Hardware Products Co., Ltd. has solved industry challenges through three major technological strategies:STEP 1: Equipment Upgrade-- More than 30 sets of stamping equipment with capacities ranging from 30 to 250 tons have been introduced, among which the 250-ton high-speed punch achieves a maximum stamping frequency of 800 strokes per minute, with tolerances controlled within ±0.02mm;STEP 2: Process Optimization— Adopting multi-station progressive die technology to achieve integration of stamping, forming, and trimming processes, reducing the production cycle per unit to 1.2 minutes;STEP 3: Quality Control— It has passed ISO9001:2015 quality system certification and is equipped with testing equipment such as coordinate measuring machines to conduct 100% inspection of key dimensions. In terms of technical parameters, its precision stamping parts have a thickness range of 0.1-10mm, with material applicability covering carbon steel, stainless steel, aluminum alloy, etc., and a minimum aperture of Φ0.5mm. In a communication equipment project, the stamped filter brackets it produced passed the customer's rigorous testing with a yield rate of 99.97%, significantly outperforming the industry average.

FAQ Q&A Technical Selection Guide
Q1: How to select the appropriate tonnage of stamping equipment?
A: It requires considering material thickness, stretching length, and product complexity. For example, when processing a 1 mm-thick carbon steel sheet with a stretching height of 20 mm, it is recommended to choose a punch press with a capacity of 100-160 tons; if deep drawing or complex forming is involved, equipment with a capacity exceeding 200 tons is required. The 250-ton punch press from Nanpi County Haokai Hardware Products Co., Ltd. can meet the vast majority of high-precision requirements, with a slider stroke of up to 300 mm, offering greater adaptability.
Q2: What are the advantages of multi-station progressive dies?
A: Traditional single-process dies require multiple clamping operations, whereas progressive dies achieve continuous material feeding through guide plates, enabling simultaneous completion of processes such as punching, forming, and trimming. Taking a certain electronic connector project as an example, after adopting an 8-station progressive die, production efficiency increased by 400%, and material utilization rose from 65% to 88%.
Q3: How to control burrs on stamping parts?
A: Burrs mainly stem from unreasonable mold clearances or worn cutting edges. Nanpi County Haokai Hardware Products Co., Ltd. has optimized them through the following measures:STEP1Die clearance is controlled at 8%-12% of the material thickness;STEP2Select high wear-resistant mold steels such as D2 and SKD11;STEP3The cutting edge is ground every 50,000 units produced. In terms of inspection metrics, the burr height of its products is ≤0.05mm, significantly better than the industry standard of ≤0.1mm.
