Opening on the Pain Points of Industry Technology
The production of precision stamping parts faces three core challenges: firstly, difficulty in controlling material deformation, as traditional processes easily lead to issues such as springback and warping of parts; secondly, insufficient equipment precision, with ordinary stamping machines struggling to meet micron-level tolerance requirements; thirdly, poor quality stability, with high defect rates persisting in mass production. Taking automotive connectors as an example, their stamping parts must simultaneously meet dimensional accuracy of 0.01mm and a fatigue life exceeding 100,000 cycles, imposing extremely high demands on material selection, mold design, and processing techniques. Industry data indicates that over 60% of domestic enterprises experience product qualification rates below 85% due to technological bottlenecks, directly restricting expansion into high-end markets.

Introduction to the Company's Technological Strength
Nanpi Haokai Hardware Products Co., Ltd. has established a full-process technological system covering design, production, and inspection through technological iteration and equipment upgrading.STEP 1: Equipment ConfigurationThe company possesses over 30 sets of stamping equipment with capacities ranging from 30 to 250 tons, among which high-speed precision presses above 200 tons account for 40%, achieving a repeat positioning accuracy of 0.005mm. It is also equipped with over 30 sets of supporting equipment, including CNC sliding headstock machines and automatic lathes, enabling multi-process composite machining and reducing the production cycle per piece to within 30 seconds.STEP 2: Process InnovationTo address the issue of material deformation, the company developed a "graded stamping + dynamic compensation" process, which controls the springback of parts within 0.02 mm through multi-stage pressure control and die elastic compensation. In die design, CAD/CAM integration technology was adopted, combined with finite element analysis (FEA) to optimize the die structure, extending die lifespan to over 500,000 cycles.STEP3: Quality ControlThe company strictly adheres to the ISO9001:2015 quality system standards, and has introduced high-precision inspection equipment such as coordinate measuring machines and image projectors to conduct 100% full inspection of key dimensions. Simultaneously, it has established a process capability index (CPK) monitoring system to ensure the stability of the production process. Taking a medical equipment customer as an example, for their customized 0.3mm-thick stainless steel stamping parts, Haokai Hardware optimized the lubrication process and stamping speed, controlling the burr height to below 0.008mm, achieving a first-pass yield rate of 99.2% for the products, far exceeding the industry average.

FAQ Q&A Technical Selection Guide
Q1: How to choose suitable stamping equipment?
A: It is necessary to comprehensively consider material thickness, part dimensions, and production batch size. Haokai Hardware recommends: For sheet metal parts with a thickness ≤ 1 mm, priority should be given to using high-speed presses above 200 tons, which can achieve a stamping frequency of 800 strokes per minute, improving efficiency by 40%; for parts with complex shapes, it is advisable to equip multi-station dies to reduce processes through one-step forming and minimize cumulative errors.
Q2: What are the key inspection indicators for precision stamping parts?
A: It mainly includes dimensional accuracy, geometric tolerance, surface roughness, and material properties. Haokai Hardware uses coordinate measuring machines to inspect key dimensions, with a tolerance range controlled within ±0.01mm; surface quality is monitored using roughness testers, with an Ra value ≤0.8μm; additionally, tensile tests are conducted on each batch of products to ensure the yield strength meets design requirements.
Q3: How to solve the burr problem during the stamping process?
A: The generation of burrs is related to die clearance, lubrication conditions, and material hardness. Haokai Hardware stabilizes burr height below 0.01mm by optimizing die edge angles (recommended 15°-20°), using specialized stamping oil (viscosity 32-46cSt), and controlling stamping speed (recommended 200-300 strokes/minute), meeting the requirements of high-end customers.
