Can Metal Stamping Cost Optimization Be Achieved Through Hybrid Manufacturing Processes?
The key to metal stamping cost optimization is not just using one process, but effectively combining them. The current paper outlines a hybrid manufacturing methodology that addresses a specific issue related to high costs associated with low-volume stamping or individual cutting operations. We explain how forming and cutting in combination provide better economic feasibility than either approach alone:
Process Deconstruction and Analysis
<オル>
Challenge Identification: For complex brackets, pure custom metal stamping services was too expensive due to multiple-stage tooling, and 5-axis laser cutting was slow and costly per unit.
Solution - Hybrid Breakdown: In order to find an optimal process chain, we decomposed the end product into various operations based on individual optimized processes.
Decision Process: A thorough analysis was made to examine the manufacturing cost of purely cutting, purely stamping, and the combined process.
Strategic Application of Forming First
Initial Hydroforming Pre-bend: This involves using a basic hydraulic press to perform the initial 3D forming of the part.
Outcome: This approach replaces the elaborate operation normally done in a costly progressive die, resulting in lower press tonnage and simpler dies.
Material Efficiency: Preliminary forming makes it possible to use a near net shape blank, which reduces waste when compared to using a flat sheet for cutting.
Precision Finishing via Optimized Stamping
<オル>
Secondary High-Precision Operation: The pre-formed part is then inserted into a single-stage precise die for finishing the part.
Operation & Benefit: This step of the hybrid metal stamping process ensures that high accuracy levels are achieved in one pass, significantly quicker than laser cutting.
Cost Result: Our process simplifies the die and, together with its use of a single operation in a hybrid process, reduces the overall cost by 60% when compared to 5-axis laser cutting alone.

By using the hybrid process we have developed a new concept of metal stamping cost optimization. We overcome the challenge of higher NRE and high part cost by utilizing an optimized approach towards manufacturing, resulting in a cost-effective metal stamping solution which provides precision at an optimally reduced manufacturing cost.

Why Is Custom Metal Stamping Services The Standard For Complex Multi-Feature Medical Housings?
The challenge in manufacturing complex medical housings incorporating snap-fits, apertures, and cosmetic finishes lies in meeting the requirement for final form accuracy without compromising the quality of the medical grade materials used. In addition to increasing costs, traditional methods involve risks such as particulates and complicated traceability requirements. Below you can learn about how our custom metal stamping services overcome this by combining all finishing techniques in one forming process:
Servo Press Control for Unified Feature Creation
Our servo presses can be programmed to de-couple slide motion and allow precise control of velocity, positioning, and holding. Thus, one stroke cycle can perform the deep draw of the cavity, stop momentarily to coin the locating flat within ±0.03mm tolerance, and create a living hinge, all while the work piece never leaves the machine. Our integrated forming metal stamping technique provides accurate control to reduce errors from handling, and thereby ensure successful initial assembly with no alignment problems.
In-Die Integration for Complex Feature Realization
We offer our tooling for complete process integration where we integrate all of the finishing processes into the die itself. In the case of a housing that requires hermetic sealing, the die will incorporate a coining operation at the end of the process where we apply high pressure to the part in order to obtain an ultra-fine surface finish. This is a process called multi-function metal stamping, a solution for complex-feature metal stamping that does not require secondary machining.
Validation-Driven Control for Regulated Environments
All of the processes comply with medical grade standards and operate under lock-and-monitored SPC. Surface roughness Ra values in-die are controlled within the specified range to ensure coating quality, adhesion and biocompatibility according to ISO 13485. The vertical control throughout the whole process chain gives us validated lots-to-lots reproducibility for submission to relevant authorities. Our precision stamping services thus become the de facto standard for critical parts.

The methodology addresses the key problem in combining several precision technologies in one consolidated and audited process. The utilization of servo control to allow unified forming and designing of process integration die results in the production of precise and fully traceable net-shaped housings for medical grade. The technology obviates secondary operations while minimizing risks of contamination.
LS Manufacturing: Automotive-Grade High-Strength Steel Chassis Components — Custom Metal Stamping Cost Optimization Solutions
A Tier-1 automotive supplier was facing serious challenges in reducing costs and increasing efficiency while manufacturing complex chassis components out of high strength steel. The company’s current hydroforming process was unacceptably costly as well as time-consuming. The case study explains how LS Manufacturing offered unique solutions by utilizing custom metal stamping services:
Client Challenge
The part was a boron steel (22MnB5) rear subframe reinforcement bracket with tight tolerance specifications of ±0.5mm. The previous hydroforming process had led to a very high unit cost of $18 and a lengthy 90-second cycle time, resulting in a weekly requirement shortage of 5,000 parts. This manufacturing cost and production gap were jeopardizing the customer’s ability to deliver under a just-in-time delivery schedule, subjecting the project to penalties for delays.
LS Manufacturing Solution
The agile engineering team adopted DFM techniques to split the intricate component geometry into two identical, stampable halves, marking the perfect case study for complex geometry metal stamping. The breakthrough was achieved using in-die resistance welding technology that enabled the joining of the two halves inside the final die station of the progressive die. Advanced computer-aided forming simulation played an essential role in estimating and offsetting the springback effect and ensuring a tight tolerance of ±0.1mm for the final assembly.
Results and Value
The new integrated process reduced the unit cost by 58%, resulting in a cost-optimized metal stamping process at only $7.50. With an increased output rate by eight times, the customer was able to achieve its fast-tracking objective and bring forward the launch by two weeks. The elimination of secondary machining on these automotive metal stamping components resulted in savings of $420,000 per car.

This case study illustrates how we approach the metal stamping optimization process. Rather than solving the problems through stamping alone, we take it one step further and optimize the entire manufacturing process itself. Our expertise in complex metal stamping and integrated assembly creates tremendous cost savings and turnaround, making LS Manufacturing the solution for challenging automotive manufacturing projects.
