Introduction:In the field of industrial manufacturing, precision stamping parts, as core components, directly determine the performance and reliability of the entire machine. Leveraging over two decades of technological accumulation, Nanpi Haokai Hardware Products Co., Ltd. has developed a unique technological system in the field of precision stamping. This article will analyze its technological path for achieving high-precision production from three dimensions: equipment configuration, process optimization, and quality control.

Keywords:Precision stamping parts; high-precision production; process optimization; quality control; Nanpi County Haokai Hardware Products Co., Ltd.

Introduction to Industry Technical Pain Points:Traditional stamping production faces three core pain points:STEP 1: Insufficient equipment accuracy- The repeated positioning accuracy of ordinary stamping equipment is only ±0.1 mm, making it difficult to meet micron-level requirements;STEP 2: Short mold lifespan— When stamping high-strength materials, the dies are prone to wear, with the service life of a single set of dies being less than 50,000 cycles;STEP 3: Significant quality fluctuations—Manual inspection is inefficient, with a missed detection rate as high as 15%, leading to batch defects. A certain automotive parts enterprise once experienced a complete batch assembly failure due to a flatness deviation of 0.05mm in stamped parts, resulting in direct losses exceeding RMB 2 million.

Introduction to the company's technological capabilities:Nanpi Haokai Hardware Products Co., Ltd. has solved industry challenges through three major technological strategies:STEP 1: Equipment Upgrade— More than 30 sets of high-precision stamping equipment with capacities ranging from 30 to 250 tons have been introduced, among which the Japanese AIDA high-speed precision punch features a repeat positioning accuracy of ±0.005mm, enabling micro-stamping at the 0.01mm level;STEP 2: Mold Innovation— Utilizing SKD11 die steel with vacuum heat treatment process, the die hardness reaches HRC60-62, extending its lifespan to over 200,000 cycles;STEP 3: Intelligent Detection— Equipped with Keyence IM-7000 series image measuring instruments with a detection accuracy of 0.001mm, the detection efficiency is improved by 5 times compared to manual inspection. Taking a project for a communications equipment customer as an example, they required a punching part hole diameter tolerance of ±0.02mm. Haokai enhanced the product CPK value from 1.0 to 1.67 by optimizing the stamping speed (reduced from 200 SPM to 150 SPM) and lubrication parameters (using KLUBER UNISILKON L 2500 lubricant), enabling it to pass the customer's acceptance inspection in one go.For more information, please visit the official website:www.hkwujin.com

FAQ Q&A Technical Selection Guide:Q1: How to choose suitable stamping equipment?
A: Three parameters need to be considered comprehensively:STEP 1: Tonnage Matching—Calculate the required tonnage based on the material thickness (t) and tensile strength (σb) (P = K × t × σb, with K ranging from 1.5 to 3);STEP 2: Accuracy Grade— Equipment with a repeat positioning accuracy of ±0.005 mm is required in the field of microelectronics;STEP 3: Production Takt Time--For mass production, it is recommended to choose high-speed punching machines with a speed above 300 SPM.
Q2: What is the key to improving the service life of molds?
A: Focus on controlling four links:STEP 1: Material Selection— ASP23 powder metallurgy high-speed steel is preferred for high-precision molds;STEP 2: Heat Treatment Process— Vacuum quenching + cryogenic treatment is adopted, with residual austenite content ≤ 5%;STEP 3: Surface Treatment— The thickness of the PVD coating is controlled at 3-5 μm, with a hardness of up to HV3200;STEP 4: Lubrication Management— Use water-soluble stamping oil with a concentration controlled at 5%-8%.
Q3: How to achieve full-process quality traceability for stamping parts?
A: Haokai achieves three major controls through the MES system:STEP 1: Batch Management—Each batch of products is bound with a unique QR code, recording information such as raw material batch, equipment parameters, and operator details;STEP 2: SPC Monitoring— Collect over 20 parameters in real time, such as stamping force and mold temperature, and generate CPK analysis reports;STEP 3: Abnormality Alert— Set threshold values for key parameters, and automatically shut down the system when the limits are exceeded while pushing alarm information to the management personnel.
