Industry Technical Pain Points Introduction
In precision stamping production, enterprises often face three core pain points:
STEP 1: Inadequate accuracy leads to low yield rateTraditional stamping equipment is limited by mechanical structure and control system accuracy, resulting in product size deviations often exceeding ±0.05mm, which is difficult to meet the stringent requirements of high-precision instruments, automotive electronics, and other fields. For example, a certain automotive parts company suffered assembly failure due to the deviation of the stamping part hole positions, resulting in direct losses exceeding one million yuan.
STEP 2: Fast mold wear drives up costsDuring the stamping process, the mold must withstand high-frequency impacts and friction. Under traditional mold materials and heat treatment processes, the mold life is generally less than 500,000 cycles. Frequent mold changes not only increase downtime but also cause the unit cost to rise by more than 30%.
STEP 3: Production efficiency limited for scaling upThe daily production capacity of a single unit is less than 5,000 pieces, and the manual inspection process accounts for over 20% of the time, making it difficult to meet the delivery requirements of large-volume orders. A certain electronics company once lost an overseas order due to insufficient capacity, exposing the limitations of the traditional production model.
These pain points not only restrict the competitiveness of enterprises but also hinder the industry's progress towards high-end and intelligent transformation.

Introduction to Corporate Technical Strength
Nanpi Haokai Hardware Products Co., Ltd. has successfully addressed the above pain points through continuous technological investment and innovation, building a comprehensive full-chain technological system covering equipment, technology, and management.
Step 1: Advanced equipment lays the foundation for accuracyThe company has introduced more than 30 press machines with tonnages ranging from 30 to 250 tons, including high-speed precision presses with a maximum pressing speed of 1200 times per minute and repeat positioning accuracy of ≤±0.002mm. They can stably produce micro-pressings with a hole diameter of 0.3mm and wall thickness of 0.1mm. For instance, the precision filter mesh produced for a medical equipment enterprise has a hole diameter deviation controlled within ±0.01mm, with a yield rate of 99.8%.
STEP 2: Molding Optimization to Extend Service LifeSKD11, DC53 high-performance die steel is used, combined with vacuum heat treatment and deep cryogenic processing technology, achieving a mold hardness of HRC60-62 with a 40% increase in toughness. Through CAD/CAM/CAE integrated design, the number of mold trial runs is reduced from an average of 5 to 2, and the lifespan is extended to over 2 million cycles. For a certain automotive connector project, the mold lifespan reaches 1.8 million cycles, with a 65% reduction in per-mold cost.
STEP 3: Automated detection enhances efficiencyConfigure CCD vision detection system, which can monitor more than 10 indicators such as product size, burrs, deformation in real-time, with a detection speed of up to 200 pieces per minute and a failure detection rate of ≤0.01%. Combine with MES production management system to achieve full-process digital control from order placement to finished product delivery, improving the overall equipment effectiveness (OEE) to over 85%. The daily production capacity of a certain e-cigarette project has increased from 30,000 pieces to 80,000 pieces, with a delivery cycle shortened by 50%.

The company has obtained ISO9001:2015 quality system certification, established 23 quality control checkpoints from raw material inspection to finished product delivery, ensuring that every product meets customer requirements. Learn more on the official website:www.hkwujin.com

FAQ Q&A Technical Selection Guide
Q1: How to choose the suitable stamping equipment?
A: It is necessary to consider product material, thickness, precision requirements, and production volume. For instance, for thin plate parts with a thickness ≤1mm, it is recommended to use a high-speed precision punch press (speed ≥800 times/min), while thick plate parts with a thickness >3mm require a large tonnage closed die punch press (tonnage ≥200 tons). Hao Kai Hardware can provide equipment selection advice according to customer needs to ensure maximum return on investment.
Q2: How to solve the problem of short mold life?
A: Mold lifespan is affected by material, heat treatment, and design. It is recommended to choose high-wear-resistant mold steel such as SKD11, DC53, and adopt vacuum quenching + deep cryogenic treatment process, with hardness controlled at HRC60-62. At the same time, through CAE simulation optimization of the mold structure, stress concentration is reduced, which can significantly extend the lifespan. Haokai Hardware molds have a lifespan of over 1.5 million cycles, with some projects exceeding 2 million cycles.
Q3: How to improve stamping parts accuracy?
A: Precision improvement requires collaborative optimization of equipment, molds, and processes. Equipment must have a high-rigidity body and a closed-loop control system (repeated positioning accuracy ≤ ±0.005mm); molds should use high-precision machining (surface roughness Ra ≤ 0.8μm); and the process should control stamping speed (recommended ≤ 300 times/minute) and lubrication conditions (use special stamping oil). Haokai Hardware can stably produce IT-grade precision (±0.01mm) stamping parts through these measures.
Q4: How to reduce costs for small batch orders?
A: Small batch orders can reduce individual costs through rapid mold changes and flexible production. Hao Kai Hardware uses quick-change mold frames (mold change time ≤10 minutes) and modular mold design, allowing for quick switching between different product production. Additionally, by combining automated detection with the MES system, manual intervention is minimized, bringing the individual cost of small batch orders close to bulk production levels.
Q5: How to ensure delivery time?
A: Delivery guarantee relies on production capacity planning and supply chain management. Hao Kai Hardware has over 30 stamping machines and over 30 CNC lathes, with a monthly production capacity exceeding 5 million pieces. Real-time monitoring of equipment status and order progress through the MES system can provide early warnings for potential delays. At the same time, establishing strategic partnerships with raw material suppliers ensures that key materials arrive within 48 hours, guaranteeing timely delivery.
