Custom Stamping Dies for Precision Metal Forming

Suichang Lvye designs and manufactures custom stamping dies for precision metal parts produced by blanking, piercing, bending, coining, and deep drawing operations.
We develop engineered tooling around your exact part geometry, material grade, press specifications, and annual volume. Every tool is built with a focus on dimensional repeatability, stable strip movement, low springback risk, and easy ongoing shop-floor maintenance.

Press Brake Louver Dies
Your clients require high efficiency in extreme heat exchange applications. Our Press Brake Louver Dies are designed to meet this requirement. They are developed for high-turbulence heat transfer
Corrugated Die
The die works with 0.15–0.5 mm aluminum and 0.12–0.35 mm stainless steel. Its continuous corrugated (wave-shaped) structure significantly increases the contact area between the fin surface and the
Staggered-tooth Die
Medium-high load applications require enhanced turbulence for efficient heat transfer. Our Staggered-tooth Die is designed for these conditions. It is compatible with 450 and 500 fin forming machines
Flat Bed Die
Small-space cooling systems require low airflow resistance for efficient heat transfer. Our Flat Bed Die is designed specifically for these applications. It is compatible with 300 and 350 fin forming

Stamping Die Selection Guide

Die Type	Target Applications	Main Production Characteristics	Engineering & Maintenance Focus
Progressive Die	High-volume small to medium precision parts	Multiple operations performed in sequence as the strip advances through stations	Strip carrier stability, pilot positioning, pitch accuracy, balanced cutting clearance
Transfer Die	Large, deep-drawn, or complex 3D components	Individual blanks or pre-forms transferred automatically between stations	Finger clearance, part positioning, springback control, automated feed synchronization
Compound Die	Flat high-precision parts requiring multiple cuts	Multiple blanking and piercing operations completed within a single stroke	Concentricity control, punch/die clearance, rigid stripper alignment
Single-Operation Die	Low-to-medium volume parts or prototyping	One primary operation, such as forming, trimming, or bending, per tool set	Lower initial tooling cost, rapid setup, manual or semi-automated loading

Integrated DFM Review & Strip Layout Engineering

Part Geometry & CAD Data: 2D (DWG/DXF) and 3D (STEP/IGS) models establish forming severity and station breakdown.

Material Properties: Yield strength, tensile strength, and sheet thickness determine press tonnage, springback allowance, and punch shear angles.

Press Line Parameters: Shut height, stroke length, bed size, feed direction, and feeder pitch interface are factored into the main die set design.

AutoForm CAE Simulation: Complex forming stations undergo digital forming simulation to identify thinning, wrinkling, or cracking risks prior to machining.

Strip Layout Optimization:
For progressive tooling, the strip layout balances material utilization with operational stability. Station sequencing prioritizes progressive stress relief, proper scrap fall-through, robust pilot engagement, and balanced carrier strength to maintain high-speed feeding up to 150+ SPM.

Tool Steel Selection & Replacement Wear Components

Selecting tool steel based on wear mechanism ensures consistent part quality while minimizing press downtime.

01/

Cutting & Piercing Punches/Inserts: High-wear areas utilize D2 (HRC 58-60), DC53 (HRC 60-62), or SKH-51 High-Speed Steel for maximum edge retention.

02/

Forming & Bending Sections: Hardened alloy steels with specialized surface treatments (TD Coating, TiN/TiALN PVD coating) prevent galling when stamping stainless steel or high-strength materials.

03/

Guide Components & Die Sets: Precision guide posts, ball cages, and bronze bushings maintain alignment under unbalanced side loads.

04/

Serviceable Construction: High-wear punches, pilot pins, and die inserts are designed as modular, quick-change components. Worn inserts can be ground or replaced directly on the shop floor without tearing down the entire die set.

Quality Control, Tryout & Validation Process

Every stamping die undergoes systematic validation from raw material incoming inspection to full production release.
Plaintext
• Material Certification Check
• Precision CNC & Wire EDM Machining
• CMM & Optical Component Inspection
• Tool Assembly & Dry Alignment Check
• T1 Press Tryout (Specified Tonnage & Material)
• Full CMM Part Inspection & ISIR Report
• Final Tool Fine-Tuning & Release
During press tryouts, engineers analyze burr height, springback compensation, material flow, pilot engagement, and automatic scrap ejection. Production approval is granted only when all critical dimensions meet your statistical capability requirements.

Applications Across Global Industries

Automotive: Structural brackets, reinforcement plates, seat frame clips, sensor housings, connector terminals

Electrical & Electronics: Lead frames, busbars, precision terminals, shielding cans, switch contacts

HVAC & Appliances: Compressor mounting plates, heat exchanger brackets, fan blade hubs, structural covers

Industrial Hardware: Heavy-duty hinges, pipe clamp components, structural connectors, precast insert plates

FAQ

Q: What is your standard lead time for custom stamping dies?

A: Standard lead time for T1 samples is typically 4 to 6 weeks for simple compound/stage dies and 6 to 8 weeks for complex multi-station progressive or transfer dies.

Q: Can you build tooling designed specifically for our existing press line?

A: Yes. We integrate your press parameters (shut height, stroke, bolster plate mounting holes, feed direction, and feeder pitch) directly into the die layout before machining.

Q: How do you ensure replacement parts fit in the future?

A: All die components are machined using 3D CAD models under strict CNC and Wire EDM tolerances. Replacement punches and inserts can be manufactured and shipped to your facility as plug-and-play spares using stored master tool files.

Q: Do you provide trial samples and dimensional inspection reports?

A: Yes. Every completed tool includes a full T1 sample lot along with a detailed CMM inspection report (ISIR) covering all drawing dimensions and critical tolerances.
