Precision Metal Stamping

Precision metal stamping differs fundamentally from standard stamping processes by demanding

ultra-tight tolerances

(typically ±0.01-0.005mm). These metal stamping components serve mission-critical functions across multiple industries, including medical devices, aerospace systems, automotive assemblies, and agricultural equipment.
Our methodology integrates high-precision tooling with advanced CNC-controlled processes, enabling high-efficiency, premium-quality mass production while maintaining surface finish standards up to Ra 0.4μm.
We specialize in

full-spectrum precision stamping

services from prototyping to volume production. Submit your component drawings/3D files to our engineering team for tailor-made die design optimization and DFM (Design for Manufacturing) analysis within 24-hour response cycle.

Core Application Areas

1.

Battery holders connection

parts: positive and negative electrode sheets, busbars, tabs

High conductivity: made of copper (C1100), aluminum (1050/1060), or nickel-plated steel strips to reduce resistance.
Corrosion resistance: surface nickel-plated, tin-plated or passivated to prevent electrolyte erosion.
Precision dimensions: thickness tolerance ±0.02mm to ensure tight fit with battery cells.
Battery holders connection parts: positive and negative electrode sheets, busbars, tabs
PCB board terminal: Installation bracket, shielding cover, grounding spring
2.

PCB board terminal

: Installation bracket, shielding cover, grounding spring

EMI shielding

:
Stainless steel (SUS301) stamping, gap ≤ 0.1mm.
High flatness: Flatness tolerance ± 0.05mm, avoiding false soldering during welding.
Miniaturization: Combination of etching and stamping processes to produce 0.2mm micro-hole structure.
Typical applications:
Shielding cover (EMI Can): Multi-chamber integrated stamping, protecting sensitive chips from interference.

Installation bracket

(Mounting Bracket):
With positioning holes and snap-fit design, improving PCB assembly efficiency.
Heat sink clip (Heat Sink Clip): Aluminum alloy stamping part, fixing heat sink and enhancing heat conduction.
3.

Electronic contact pieces

: Commonly used in connectors, switches, and sensors. For example: SIM card contacts and

battery spring pieces

.

Elasticity and durability: Materials commonly used are phosphor bronze (C5191) and beryllium copper (C17200), with a cycle life of over 100,000 times.
Contact reliability: Surfaces are gold-plated (0.1-0.3μm) or silver-plated to reduce contact resistance (<10mΩ).
Electronic contact pieces: Commonly used in connectors, switches, and sensors. For example: SIM card contacts and battery spring pieces.

Quality of Precision metal stamping

We provide you with metal stamping design and production services.
Shengyi Intelligent Technology has always been focused on high-precision solutions for electronic precision stamping parts. We can provide customers with

micron-level precision control

and

professional inspection reports

. The core of precision stamping is to complete multiple processes such as punching, bending, and forming through continuous stamping with precision progressive dies and compound dies in one or more sets of molds.
Process Optimization and Cost Control
In addition, Shengyi has unique experience in the development of precision molds. We customize mold design and development for precision hardware parts of different quantities, accuracies, and complexities to ensure high efficiency, high quality, and stability during production.
Optimize material utilization through CAD nesting software to reduce waste output.
We guarantee daily mold maintenance to extend the mold life to 2 million times.
We offer

comprehensive post-processing

and

surface treatment services

to achieve various functional requirements for precision metal stamping parts. For instance, we can provide functional treatments or precision processing such as gold plating, nickel plating, and tin plating through electroplating to ensure the parts have anti-oxidation, corrosion resistance, and improved weld ability. We also apply epoxy resin powder and Teflon coating to make the stamping parts insulating or wear-resistant. Additionally, we use acid washing to enhance the corrosion resistance of precision stamping parts.

Frequently Asked Compression Spring Questions (FAQs)
  • 1

    What are the minimum wire diameter and thickness for precision metal stamping?

    Wire diameter: Supports a minimum wire diameter of 0.03mm (such as medical catheter springs).
    Plate thickness: Can process metal plates ranging from 0.05mm to 6.0mm, covering the needs from micro electronic components to heavy structural components.
  • 2
    Does it support rapid prototyping? What is the cycle and cost?
    Yes, we support rapid prototyping. Through laser cutting + manual bending, the cycle: Sample delivery in 3-5 days.
    Production cost is approximately 5-10 times the production unit price (depending on complexity)
  • 3

    How is multi-material composite stamping achieved?

    Process plan:
    Layered stamping: Different material layers are stacked and formed as a whole (such as steel-aluminum composite heat sink).
    Bolted/welded integration: After stamping, laser welding of different materials is carried out.
    Example: Copper-aluminum composite current collector in automotive battery modules, balancing conductivity and cost.
  • 4
    After the design changes, can the existing molds be modified? What about the cost?

    Mold modification: Partial adjustments are supported (such as the punching position and bending angle). The modification cost is approximately 20% - 50% of the cost of a new mold.
