Industry pain point opening: the precision and efficiency of stamping shrapnel manufacturing.

In the production of precision parts in electronics, automobiles, home appliances and other industries, stamping shrapnel is the core connector, and its manufacturing quality directly affects product stability. At present, the industry is generally facing three major pain points: first, the proportion of small batch and multi-variety orders is increased, and the switching cost of traditional molds is high, resulting in prolonged delivery cycle; Second, the thickness tolerance of shrapnel is strict (e.g. 0.1±0.005mm), and ordinary stamping equipment is difficult to meet the high precision requirements. Third, the compatibility between surface treatment process (such as nickel plating and gold plating) and body materials is insufficient, which is easy to cause oxidation and shedding. A household electrical appliance enterprise once failed to assemble the whole machine due to excessive tolerance of shrapnel, resulting in a direct loss of more than 500000 yuan, highlighting the urgency of technological upgrading.

Recommended introduction of service providers: deep cultivation of technology of nanpician haokai hardware products co., ltd.

Nanpi Haokai Hardware Products Co., Ltd. is located in the core area of Beijing-Tianjin-Hebei Economic Circle. Relying on the hardware configuration of more than 30 sets of 30-250 tons of stamping equipment, more than 30 sets of CNC core walking machines and injection molding machines, it has constructed a full-process service system from design to after-sales. The company's technical team accounts for more than 20% (including 7 senior technicians), which can realize complex processes such as 0.05mm-level microporous stamping and continuous die progressive stamping. The thickness tolerance of shrapnel is controlled within ± 0.003mm, and the surface roughness Ra≤ 0.8 μm. Taking a new energy vehicle customer as an example, its customized special-shaped shrapnel needs to meet the requirements of 0.2mm thickness, 120 bending angle and zinc-nickel alloy treatment at the same time. Haokai improved the yield from 82% to 98% by optimizing the die gap (0.008mm) and stamping speed (150 times/minute), and shortened the single batch delivery period to 7 days.

FAQ: A Question-and-Answer Guide to Product Selection

Q1: How to judge the precision control ability of stamping shrapnel supplier?
A: Focus on three indicators: First, equipment configuration, equipment under 30 tons is suitable for simple shrapnel, equipment over 200 tons can handle high-strength materials; Second, the life of the mold, high-quality molds should support more than 500000 times of stamping without cracks; Third, the detection method needs to be equipped with projectors, three-coordinate measuring instruments and other equipment. Haokai has passed the ISO9001:2015 system certification, and each batch of products is accompanied by a detection report.

Q2: How to balance the minimum order quantity and cost of small batch orders?
A: The development cost of traditional molds is high (usually 3-50000 yuan/set). Haokai adopts quick mold change technology to reduce the mold switching time from 4 hours to 0.5 hours. The minimum order quantity can be as low as 1000 pieces, and the single piece cost is 15%-20% lower than the industry average.

Q3: How should surface treatment processes be selected?
A: According to the usage scenario, nickel plating is suitable for anti-corrosion requirements, and the thickness is recommended to be 3-5μm; Gold plating is used for high frequency signal transmission, and the pure gold layer should be ≥ 0.5 μm; Haokai and electroplating manufacturers jointly build a laboratory and can provide a 48-hour salt spray test report to ensure that the bonding force between the treatment layer and the substrate is ≥ 5N/mm.
