Why Does Mold Stability Define Part Consistency In High Volume Metal Stamping?

In high volume metal stamping, mold stability directly determines part consistency. Mold wear or deviation can lead to batch scrap and increased costs. Simply put, mold stability is the customer's cost control line and is key to achieving high output and high precision.

Selection Logic of Carbide Materials and PVD Coatings

1. The custom metal stamping service allow customers to select ASP 23 carbide punches which have a hardness of HRC 64-66 and provide more than three times the wear resistance of standard high-speed steel, which results in lower punch wear.
2. The 2-5μm PVD coating reduces the coefficient of friction between the punch and the material, which produces less heat during stamping and prevents thermal expansion from reaching dangerous levels.
3. The material and coating combination provides effective mold life extension, which results in less frequent mold replacements and decreased costs for mold acquisition and replacement.

Application of Thermal Compensation Technology and Tonnage Monitoring

The stamping process experiences dimensional changes because of mold friction heat in high-volume operations. Our team uses thermal compensation technology to monitor and adjust parameters as we operate, which helps maintain stamping dimensions within Cpk > 1.33 limits. The tonnage monitoring system detects tonnage anomalies, which enable it to issue early warnings about mold failures that result in production waste.

How Does Precision Stamping Service​ Balance Rebound & Flatness For Ultra-Thin Materials?

During the precision stamping service for 0.1mm~0.5mm ultra-thin materials, springback and flatness problems often occur.

If not handled well, the parts may not assemble and rework cost can be increased. With the scientific process optimization, we afford high precision parts for our customers.

Mathematical Modeling and Application of Springback Compensation

• For the various ultra-thin materials you select, LS Manufacturing would draw up a special mathematical model of springback compensations to precisely analyze the core parameters including the elastic modulus and yield strength of material.
• During die design stage, an accurate spring back calculation with the model gives compensation space to be planned in advance, so that no deviation in parts dimension will result from the stamping process.
• Effective die design considering material characteristics will reduce the stamping stress concentration thus to minimize the impact of springback and maintain part dimensional accuracy.

Progressive Die Design and Process Optimization

For progressive die design, several pre-bending and pre-leveling procedures are utilized to successively alleviate the internal stress of the material. With a finely controlled oil mist lubrication system to minimize the friction, flatness of the work piece could be maintained within 0.05 mm.

Processing Method	Flatness (mm)	Heat Affected Zone (mm)	Applicable Output (pieces/month)	Cost (USD/piece)	Surface Roughness (Ra/μm)	Applicable Material Thickness (mm)
Precision Stamping Service	≤0.05	None	100,000-1,000,000	0.12-0.35	≤0.8	0.1-1.5
Laser Cutting Service	0.10-0.20	0.3-0.5	1,000-10,000	0.80-1.50	1.2-2.0	0.1-2.0
Ordinary Stamping	0.20-0.35	None	50,000-300,000	0.25-0.60	1.0-1.8	0.5-3.0
Waterjet Cutting	0.15-0.25	None	500-5000	1.50-3.00	1.5-2.5	0.3-5.0

How To Cut Costs & Boost Efficiency Via Progressive Dies In High Volume Stamping Service?

The two most basic requirements for high volume stamping service is high output and low cost. High-speed multi-station progressive dies or single stamp die which should be selected directly affects the efficiency and cost output. Proper selection is an important means of cost saving.

Economic Balance Point Analysis of Progressive Dies and Single-Stamp Dies

Our test data shows that the economic balance point between progressive dies and single-stroke dies is 100,000 units: single-stroke dies are more cost-effective for orders below 100,000 units, while progressive dies with 20 or more stations are used for orders above 100,000 units. Although the initial investment is higher, it can reduce costs and increase efficiency.

Practice of Automating Integration and Eliminating Processes

We used an automatic feeder incorporating internal die tapping capabilities to combine secondary metal working operations into one stamping operation.

By eliminating multiple operations per cycle in the stamping process, this improvement decreases production cycle time by 25 percent and decreases labor cost by 30 percent.

Through our custom metal stamping service, we have compiled a lot of successful examples in high-precision fields. Our stainless steel shielding cover stamping project for medical products can be viewed as an ideal example to illustrate our competencies in tackling difficulties and generating value.

Customer Challenges

One of the top 3 worldwide medical device OEM encountered two of their major problems when manufacturing 0.15mm SUS304 shields covers of 2mm width: pop-up micro-cracks at the bending points led to EMI non-compliance (now a 12% PCB interference rate), and the current supplier simply could not reproduce a consistent cover at 1 million units/month production quantity (scrap rate at 8%, cost increased exponentially).

LS Manufacturing Solution

After our intervention, we first conducted DFM analysis on the parts and found that the core cause of microcracks was the concentration of single bending stress, while the poor consistency was due to insufficient mold accuracy and unreasonable processes. We have taken a series of optimization measures to address these issues:

1. Process Optimization: We replaced the one step bending process with a three stage progressive bending process to gradually release the internal stress of the material to fully resolve the micro crack issue occurring at the bend site.
2. Die Optimization: We employed very fine-grain carbide dies with a micronized oil mist lubrication system which led to less die wear and resulted in tight part dimension control.
3. Inspection Optimization: We carried out 3D contour comparison with laser scanning of the first piece, to be able to the gap parameters of the stretching die to optimize 0.005mm, so as to ensure every part to be able to the accuracy.
