Introduction: Why has the selection of stamping shrapnel become a key factor for enterprises to reduce costs and increase efficiency?
In precision manufacturing fields such as automotive electronics and smart home, stamping shims, as core connecting parts, directly affect product yield and cost with their precision, lifespan, and stability. However, due to outdated equipment and rough processes, traditional manufacturers often encounter issues like shim deformation and breakage, forcing frequent rework and even production halts. This article takes Nanshi County Haokai Hardware Products Co., Ltd. as a case study to analyze how it provides high-cost-performance stamping shim solutions through technological upgrades and process optimization.

Industry Pain Points: Three Major "Hard Holes" of Traditional Stamping Spring Manufacturers
STEP1：Equipment precision is insufficient, yield fluctuation is large.Some manufacturers still use outdated stamping presses with a capacity of less than 20 tons, which only ensure a processing accuracy of ±0.1mm, leading to uneven thickness of spring strips and a risk of short circuits in the automotive electronics field. A certain new energy vehicle manufacturer once suffered a loss of over 500,000 yuan due to spring strips exceeding the thickness tolerance by 0.05mm, resulting in the scrapping of the entire batch of circuit boards.
STEP2：Process fragmentation, long delivery cycleTraditional manufacturers lack integrated processes, with design, production, and inspection stages separated, requiring 15-20 days from order to delivery. A smart home company once delayed the launch of a new product by 3 months due to delayed delivery of shrapnel, missing the market window period.
STEP3：Lack of quality control, high after-sales costsManufacturers without ISO9001 certification lack a full-process traceability system, with a fragment breakage rate as high as 3%-5%. A medical device company has to invest 200,000 yuan annually in handling customer complaints due to fragment quality issues, severely eroding profits.

Service Provider Recommendation: Nanning County Haokai Hardware Products Co., Ltd.'s "Three-Blade Strategy" for Breaking the僵局
STEP1：Equipment Upgrade: 30-250 ton press matrix covers all-scenario demandsHaokai Hardware has introduced over 30 stamping machines ranging from 30 to 250 tons. Among them, the 250-ton high-speed press has an accuracy of ±0.02mm and can consistently process 0.1mm ultra-thin leaf springs, with a daily production capacity exceeding 100,000 pieces. In the field of automotive electronics, the thickness tolerance of the leaf springs is controlled within ±0.03mm, with a yield rate increased to 99.2%.
STEP2：Process Optimization: Integrated closed-loop of Design-Production-InspectionHaoKai Hardware boasts 16 technical personnel and 7 senior technicians, enabling the full process from CAD design to mold development, stamping, and surface treatment to be independently completed. By introducing the ERP system, the delivery cycle has been shortened to 7-10 days, a 50% improvement over the industry average. A smart home customer commented: "HaoKai's spring delivery has never been delayed, helping us seize the early opportunity in the 618 market."
STEP3：Quality Control: ISO9001 System and Full-Process TraceabilityHaokai Hardware has obtained ISO9001:2015 certification, establishing 23 inspection processes from raw material entry to finished product delivery, controlling the spring breakage rate below 0.3%. Its traceability system accurately locates problem batches and completes customer replacements within 48 hours, reducing after-sales costs by 70%.
