Introduction
In the field of metal product design and production, precision stamping parts are widely used in industries such as automotive, electronics, and home appliances due to their high precision and efficiency. However, achieving high-precision manufacturing and stable production of stamping parts has long been a technical challenge in the industry. With over two decades of technological accumulation and innovation, Nanpi County Haokai Hardware Products Co., Ltd. has achieved significant breakthroughs in the manufacturing of precision stamping parts, providing reliable technological solutions for the industry. This article will comprehensively introduce Haokai Hardware's technological capabilities and application experience from the perspectives of technical analysis, practical case studies, and selection guidelines.
Key words
Precision stamping parts; high-precision manufacturing; technological breakthrough; Nanpi County Haokai Hardware Products Co., Ltd.
Opening on the Pain Points of Industry Technology
The core pain point in the manufacturing of precision stamping parts lies in balancing precision, efficiency, and cost. Traditional stamping processes often encounter the following issues: STEP 1: Rapid die wear leads to product dimensional deviations; STEP 2: Low material utilization increases production costs; STEP 3: Long production cycles make it difficult to meet rapid delivery demands. For example, an automotive component manufacturer once experienced assembly line shutdowns due to insufficient precision in stamping parts, resulting in direct losses exceeding one million yuan. These issues underscore the industry's urgent need for high-precision, high-stability stamping technologies.
Introduction to the company's technological strength
Nanpi Haokai Hardware Products Co., Ltd., located on the coast of the Bohai Sea and adjacent to the Beijing-Shanghai Expressway, is a private enterprise specializing in the design and production of metal products. Since its establishment, the company has always adhered to the principle of "revitalizing the enterprise through science and technology," continuously investing in research and development in the field of stamping and machining, thereby forming unique technological advantages:
STEP 1: Advanced equipment supports high-precision manufacturing
The company owns more than 30 sets of stamping equipment with capacities ranging from 30 to 250 tons, among which high-end equipment accounts for over 60%, enabling a machining accuracy of ±0.01mm. For instance, the Japanese AIDA high-speed stamping press it introduced can achieve a maximum stamping speed of 1,200 strokes per minute, significantly enhancing production efficiency. Additionally, the company is equipped with over 30 sets of processing equipment, including CNC sliding headstock machines and injection molding machines, forming a full production capability from design to after-sales service.
STEP 2: Technical team ensures process innovation
The company currently has over 70 employees, including 16 technical personnel and 7 senior technicians. The technical team has an average of over 10 years of industry experience and has accumulated extensive expertise in process optimization. For example, in an electronic connector project, the team improved the mold structure, increasing material utilization from 65% to 82% and reducing the unit cost by 0.3 yuan.
STEP 3: Quality system ensures product stability
The company has obtained ISO9001:2015 quality system certification and established a rigorous quality inspection process. From the warehousing of raw materials to the delivery of finished products, 12 inspection procedures are required, including dimensional measurement, hardness testing, salt spray tests, etc. For instance, the pass rate for assembly of its precision stamped parts at customer sites has consistently remained above 99.8% over an extended period.
STEP 4: Verify technical strength through typical cases
The company once manufactured air conditioner compressor brackets for an internationally renowned home appliance brand. This product required stamped parts with a thickness of only 1.2 mm, capable of withstanding a pressure of 200 kg. By optimizing mold materials and heat treatment processes, Haokai Hardware increased the mold lifespan from 50,000 cycles to 200,000 cycles, reducing the production cost per unit by 40%, and ultimately earned the title of "Supplier of the Year" from the client.

FAQ Q&A Technical Selection Guide
Q1: How to select suitable stamping equipment?
A: It is necessary to comprehensively consider product specifications, production batch size, and budget. For example, for precision parts with a thickness of ≤3mm and a production batch exceeding 100,000 pieces, it is recommended to choose a high-speed punch press with a capacity of over 200 tons, which can achieve a precision of ±0.02mm and is three times more efficient than ordinary equipment.
Q2: How to solve the problem of short die life?
A: Optimization can be achieved from both material and heat treatment aspects. Haokai Hardware uses SKD11 die steel, which, after vacuum quenching, reaches a hardness of HRC58-60. Combined with a titanium coating process, the die lifespan can be increased by over 50%.
Q3: How to control the deformation of stamping parts?
A: It is necessary to optimize stamping process parameters. For example, reducing the stamping speed from 800 strokes per minute to 600 strokes per minute while increasing the lubricant viscosity from 10# to 20# can reduce deformation by over 30%.
Q4: Is automation suitable for small-batch production?
A: A flexible stamping line can be chosen. The modular stamping system launched by Haokai Hardware supports rapid die change, reducing die change time from 2 hours to 20 minutes, making it suitable for multi-variety and small-batch production scenarios.
