Introduction
In the field of metal product processing, the production of precision stamping parts imposes extremely high demands on equipment accuracy, process control, and quality inspection. Leveraging over two decades of technical expertise, Nanpi County Haokai Hardware Products Co., Ltd. has established a comprehensive technical system spanning from design to after-sales service by introducing more than 30 sets of 30-250 ton stamping equipment and advanced machinery such as CNC sliding headstock machines. This article will analyze its technological advantages in precision stamping part manufacturing from dimensions including technical principles, equipment configuration, process parameters, and practical application cases.

Introduction to Industry Technical Pain Points
Traditional stamping part manufacturing often faces three major technical bottlenecks: First, insufficient equipment precision leads to product tolerances exceeding standards. For example, when stamping a metal sheet with a thickness of 0.5 mm, ordinary equipment may produce an error of ±0.1 mm, whereas high-precision requirements demand control within ±0.02 mm. Second, fragmented process flows result in low efficiency; if design, processing, and inspection are not integrated, the production cycle for a single part may be extended by 30%. Third, the lack of a quality traceability system makes it difficult to pinpoint the root causes of issues in production processes through data-driven means. These problems directly lead to a decline in product yield, extended delivery cycles, and an increase in customer complaint rates.

Introduction to the company's technological capabilities
Nanpi County Haokai Hardware Products Co., Ltd. addresses industry pain points through the following technological布局:
STEP 1: Equipment Configuration UpgradeMore than 30 sets of stamping equipment with capacities ranging from 30 to 250 tons have been introduced, among which the 250-ton stamping press can exert a maximum pressure of 2500 kN and stably process metal sheets with a thickness of 8 mm; Additionally, 10 sets of CNC sliding headstock lathes are equipped, with spindle speeds reaching up to 12,000 rpm, achieving micron-level cutting precision and suitable for processing precision shaft parts with diameters ranging from 2 to 20 mm.
STEP 2: Process Flow IntegrationAn integrated process of "design-processing-inspection" is adopted, enabling direct connection between design data and processing equipment through CAD/CAM software and reducing manual intervention. For example, in a certain automotive instrument bracket project, this process shortened the production cycle per unit from 72 hours to 48 hours and increased the yield rate from 92% to 98%.
STEP 3: Standardization of Quality InspectionImplementing the ISO9001:2015 quality system, we are equipped with testing equipment such as coordinate measuring machines and projectors to conduct 100% inspection of key dimensions. Taking a connector for medical equipment as an example, its bore diameter tolerance requirement is Φ5±0.01mm. Through detection with the coordinate measuring machine's 0.001mm-level precision, we ensure that all products meet the standards.

FAQ: Q&A Guide for Technology Selection
Q1: How to select the appropriate tonnage of stamping equipment?
A: It requires considering material thickness, stretching length, and product complexity. For example, when processing a U-shaped part with a thickness of 2mm and a stretching length of 50mm, it is recommended to select a stamping press with a capacity of 100-160 tons. If the product involves multi-stage stretching or complex curved surfaces, priority should be given to configuring stamping equipment with servo control, which offers 40% better pressure stability compared to ordinary equipment.
Q2: What are the core differences between CNC sliding headstock machines and conventional lathes?
A: The CNC sliding headstock machine achieves high-precision machining through synchronized control of spindle rotation and tool feed, with spindle runout ≤ 0.002mm, whereas ordinary lathes typically have spindle runout ranging from 0.01-0.02mm. Taking the machining of a 10mm-diameter shaft part as an example, the CNC sliding headstock machine can achieve a surface roughness of Ra0.8μm, meeting the high standards required in the medical and aviation fields.
Q3: How can the yield of stamping parts be improved through the optimization of process parameters?
A: Focus on controlling three parameters: First, the stamping speed. For high-strength steel plates (e.g., with a tensile strength ≥ 600 MPa), the speed should be controlled between 100-300 strokes per minute to prevent material cracking. Second, the die clearance, which is typically set at 8%-12% of the material thickness; for example, the die clearance for a 1 mm-thick plate should be set between 0.08-0.12 mm. Third, the lubrication method; using water-based lubricants can reduce the friction coefficient by 30% and extend die life by more than twice.
