Advantages of Ultra-Thin Metal Material Stamping Technology
What LS Manufacturing can do is precision stamping on fragile 0.05mm thin metallic materials without ever waviness and more burrs (Burr), < 0.02mm. This core process technology on LS Manufacturing is customized to produce micro-punches that reduce uneven force distribution. Micro-lubrication system (MQL) reduces friction.
We have previously etched a 0.05mm thick stainless steel shield for an Electronics customer. Conventional suppliers will produce 0.05mm burrs and significant deformation. LS Manufacturing eliminated 0.015mm burrs and deformity 0.003mm by process and die optimisation to meet our customer's requirements and save on the cost of grinding combined with our integrated laser cutting and stamping services.

LS Manufacturing Case Study: Custom Development Project For High-Precision Stamped 316L Stainless Steel Surgical Scalpel Handles
Medical grade component stamping needs very tight tolerances, surface quality, and materials stability. The handle of surgical scalpel 316L stainless steel directly relate to the safety of the operation.
Here, included a full case of LS manufacturing custom development for 316L surgical scalpel handle for our customers, demonstrate our full service advantages.
Client Challenges
The client is a global medical device manufacturer. Their current supplier faced two significant issues with 316L surgical handle manufacture:
<オル>
The requirement for very rapid material hardening caused a set of punching tools to be worn out after 5,000 pieces. This high tooling cost led to low efficiency.
Ra of surface roughness > 1.6μm so just needs further grinding, both impart to rise cost and may impart dimensional deviation.
The customer has dealt with many metal stamping suppliers before without resolution of the issues causing this project to come to a halt and around 15 weeks behind schedule against the delivery risk.
They desperately needed a professional custom metal stamping service which specialized in medical stamping components orders.
LS Manufacturing Solutions
The client's request was so that LS Manufacturing set up a special engineering team to take care of the project. Based on our experience in medical parts stamping, we have performed several testing and solution optimization. Listing some of our measures:
<オル>
Die and Punch Optimization: in a series of CAE runs we optimized for drawing ratio on the 12-station progressive die from the initial speed of 30mm/sec to the reduced 20mm/sec to minimize the material's characteristic of hardening. At the same time, for the punch, ASP-23 superhard alloy was used and DLC coating was applied for its enhanced wear resistance.
Process temperature control: a special Micro-Lubrication System (MQL) was implemented, and the working temperature of the die was decreased by 15℃. The thermal stress was well inhibited leading to a decreased hardening effect of the material and a decreased punch breakage from high temperature wear.
Surface quality optimization: The stamping clearance was optimized to 10% of the material thickness and costly high precision polishing dies were used to decrease surface scratch width. In addition, an online polishing process was introduced to make the surface surface roughness suitable. As a result, no grinding treatment was necessary.
Better Quality Control: All products are checked on the Zeiss CMM measuring equipment and surface roughness is measured with specialist instruments to regulate the tolerances of 0.005mm and Ra0.8um which are suitable for medical grade requirements.
結果と値
A number of great increases in efficiencies were delivered following solutions optimization. The punch life was improved from 5,000 cycles to 80,000 cycles, a 93.75% reduction in wear costs. Surface roughness was kept at Ra 0.8um without the requirement to grind, saving $0.1/piece, price reduction was achieved by 45% to procuring costs which was successful to making the client's product became much more competitive and able to relaxing the client's attention on medical precision stamping.
The end customer moved long-term contract manufacturing order from RapidDirect to LS Manufacturing and added three new projects on same part family (Medical stamping parts) fully aware of LS Manufacturing technical and service capabilities.

How To Balance Logistics Lead Time And Quality When Sourcing From China Metal Stamping Service Providers?
By 2026, evaluation of procurement competition will be conducted based on technology and delivery time. When sourcing Chinese metal stamping service:LS Manufacturing through modular mold design can reduce prototyping time to 7-10 days which is 30% faster than competitors such as Hubs.This can give clients an edge over other competitors in the industry.
Geographical and Supply Chain Advantages
LS Manufacturing production bases reside in the said and Yangtze River Delta regions. No other cross-regional cooperation is needed to provide secondary processing services like vacuum electroplate and heat treatment. This reduction shortened the production cycle by 3-5 days, handle the stamping order delivery efficiently.
Production and Logistics Management Measures
Modular Mold Design: Standardized modules are used for different parts of the mold, making modules reusable. No need for full re-make of the prototype instead of ten to fourteen days of the traditional cycle, which accelerates prototype manufacturing by 30%.
ERP System sharing in real-time: Customers can check the production status as well as testing report at anytime, saving communication time and allowing information sharing from the system.
Deep logistics integration: targeted offering DDP services with DHLFedEx, all customs clearance and transportation will be managed in the initiated process, delivery between NA and Europe region can be settled in within 5~7days which is 2~3 days faster than industry average, solve overseas procurement customs clearance problem to gain international stamping supply.
What Factors Determine The Final Quotation For a Metal Stamping Service Project In China?
The quotation ofmetal stampingservicesin China including material, mold (NRE), and unit price. Those are the basic criteria influencing the last quotation of the metal stamping service project China. LS Manufacturing applies transparent accounting of spreading mold fee evenly to all bulk orders.If MOQ goes over 10 000 unit price is more than 20%, cheaper than Protocolabs.
Core Components of a Quotation
<オル>
Material cost: which accounts for 40%~60% of the quotation.It depends on the material type (SUS316L, for example, is about 30% more expensive than ordinary carbon steel), thickness and utilization rate.
Cost of Mold (NRE): A fixed, one-time cost which varies with the number of pieces in a batch, the die complexity and build material.Single cell dies start at around $2,000 while complex progressive stamping dies start at $8,000 and go up to $20,000 or more. This is amortized over the batch.
Unit Price: Labor, equipment depreciation and second processing costs.It varies with batch size or quantity, the larger the batch size or quantity, the lower the unit price, and the complexity of the process.
Hidden Cost: Covers material wastage rates and additional processing charges. Proper means of action on part of merchandiser can minimize such cost.
Cost Optimization and Price Comparison
Cost is reduced by process improvement. For instance, if single-stamp die is switched to a progressive die, this will cost at least 30% less labor, and 50% more efficiency. Then the unit price of the bill of 100K will be 20%-25% less. And this is the fundamental cost advantage of "stamping service China 2026". These detail is a set price comparison for 100Kssus316L parts (unit:USD), which is the most optimized low-cost stamping solution.
