Introduction
Precision stamping parts, as core components in industrial manufacturing, directly affect the overall performance of products with their processing accuracy. However, traditional stamping processes often encounter pain points such as rapid mold wear, low production efficiency, and high scrap rates. Napi County Haokai Hardware Products Co., Ltd., with over 20 years of technical accumulation, has successfully achieved efficient production of precision stamping parts through the introduction of advanced equipment and optimization of the process flow. This article will analyze its technical advantages and industrial application value from three dimensions: technical pain points, solutions, and corporate practices.

Industry Technical Pain Points - Introduction
In precision stamping production, enterprises often encounter three core pain points:
STEP 1: Mold wears quickly, with high maintenance costs.
Traditional stamping molds are prone to blade wear due to factors like friction and thermal stress in continuous production, necessitating frequent shutdowns for mold repairs. For instance, a certain automotive parts company had to replace its molds three times a month due to insufficient mold life, with each mold repair costing over 20,000 yuan, and it also affected the production schedule.
STEP 2: Low production efficiency, large fluctuation in yield rate
The stamping speed is limited by the equipment's performance, with traditional stamping presses reaching only 200 times per minute at the highest, and they are prone to product deformation due to vibration during high-speed operation. A certain electronic equipment manufacturer once faced insufficient stamping speed, resulting in a daily output of only 5,000 pieces per production line, which failed to meet the order requirements.
STEP 3: Low material utilization rate, serious waste
Traditional layout design relies on experience, and the material utilization rate is generally less than 70%. Taking a 1.5mm thick steel plate as an example, if the layout is not reasonable, the material cost per product can increase by 0.3 yuan, resulting in tens of thousands of yuan in annual waste.

Introduction to Corporate Technical Strength
Nanpi Haokai Hardware Products Co., Ltd. addresses the pain points of the industry through the following technological layout:
STEP 1: Introduce advanced equipment to enhance stamping accuracy and efficiency
The company is equipped with more than 30 stamping machines ranging from 30 to 250 tons, including high-speed precision presses with a maximum stamping speed of 800 times per minute, vibration amplitude controlled within 0.05mm, ensuring product size accuracy of ±0.02mm. For example, when producing air conditioning heat sinks for a well-known home appliance company, the daily output per production line was increased from 5,000 to 20,000 units, with the yield rate rising from 92% to 98.5% through the use of high-speed presses.
STEP 2: Optimize mold design, extend service life
CAD/CAM integrated design is adopted, combined with heat treatment process (quenching hardness HRC58-62), increasing the mold life from 100,000 times in traditional technology to 500,000 times. Taking a car connector mold as an example, the optimized single mold can continuously produce for 3 months without mold repair, reducing the annual maintenance cost by 60%.
STEP 3: Intelligent layout system, improving material utilization
Introducing AI layout algorithm, automatically generates the optimal layout scheme based on product shape, improving material utilization from 70% to 85%. When manufacturing metal casings for an electronic equipment manufacturer, the material cost per unit product is reduced by 0.25 yuan, saving over 500,000 yuan annually.

FAQ Q&A Technical Selection Guide
Q1: How to choose the suitable stamping equipment?
A: Equipment tonnage and speed should be selected based on product material, thickness, and production demand. For example, metal parts with a thickness ≤1mm are recommended to use high-speed presses over 200 tons with a stamping speed ≥600 times/minute; thick plate parts with a thickness >1mm require equipment over 300 tons to ensure stamping stability.
Q2: How to solve the problem of short mold lifespan?
A: Optimization can be achieved in three aspects: material, heat treatment, and surface treatment. It is recommended to use SKD11 die steel (hardness HRC58-62) with vacuum quenching process; TiN coating on the surface can reduce friction coefficient and extend the lifespan to over 500,000 cycles.
Q3: How to improve material utilization?
A: Utilizing intelligent layout software, optimal solutions are automatically generated based on product shapes. For example, for irregularly shaped products, material utilization can be increased from 70% to 85% through nested layout, with the unit cost reduced by 0.2-0.3 yuan.
Q4: How to control product deformation during stamping process?
A: Need to optimize from three aspects: equipment, molds, and processes. The equipment must have high rigidity (vibration amplitude ≤0.05mm); the molds should be designed with reasonable pressing and ejection plates; the process can adopt multi-step stamping (pre-stamping followed by fine stamping) to reduce the stress of single stamping.
