Standardization of Metal Stamping Molds

Metal stamping is a crucial manufacturing process, shaping raw materials into precision components used across various industries. At the heart of this process are the metal stamping molds, instrumental in achieving consistency, accuracy, and efficiency in production. The standardization of these molds plays a pivotal role in elevating the quality of stamped parts and streamlining the entire manufacturing workflow.

1. Mold Design Standard Structural Diagram

No.	Standard Parts Diagram
A	Upper Limit High Pillar: Functions to ensure the precision of mold closure and prevent parts from being damaged.
B	Upper Mold Spring and Equi-height Sleeve: Functions to aid in ejecting the molded part
C	Upper Mold Pin: Functions to precisely fix and locate the upper mold base, upper bolster, and clamp plate.
D	Upper Mold Screw: Functions to secure the mold plate.
E	Misumi Inner Guide Post and Guide Sleeve: Functions to bear the precision of the entire set of mold components.
F	Misumi Outer Guide Post and Guide Sleeve: Functions to bear the precision of mold components and ensure alignment between upper and lower molds.
G	Ejector Pin: Functions to fix and position the fixed plate and ejector plate.

J	Lower Mold Screw: Functions to secure the lower mold plate.
K	Lower Mold Pin: Functions to precisely fix and locate the lower mold base, lower bolster, and lower mold seat.

2. Standard Specifications for the Layout of Material Strips in Mold Design

No.	Layout Diagram
1	Holes with high positional tolerance requirements or those prone to breakage need to be punched simultaneously; as shown in figures 1/2.
2	If there are holes for bending or other processes with high positional accuracy requirements, punch them after bending. This can avoid inaccuracies in unfolding that may affect dimensions; as shown in figures 11/12 for bending, and figure 13 for cutting after bending.
3	In cases where there is symmetrical bending in the product, synchronous bending needs to be designed; as shown in figures 21/22/23.
4	Processes like stretching or others that may affect dimensions during forming need to be addressed in advance; as shown in figure 10 with stretching first, followed by forming in figures 15/16.
5	For variations in the production process, adjustments to parts need to be increased, reducing the need for maintenance of the lower mold during production; as shown in figure 19.

3. Design Standards for Mold Components

Cutting Station Design Standards

The drawing should specify the processing technology, where K represents fast cutting, M represents slow cutting, Y represents grinding, F represents discharge machining, X represents milling, PG represents wire cutting, and YG represents oil cutting. For precision blade drawings, the requirements are YG oil cutting – Y grinding – F discharge machining.
Material selection for components, such as ASP23, ASP60, WC, DC53, SKD11, SKH-9, SKH-53. Different materials should be applied based on the characteristics of the plate. For cutting punches, ASP60 with an HRC of 62 degrees is prioritized.
For soft materials with a thickness t < 1MM, the blade gap is c = (3%-4%) t; for t = 1MM-3MM, the blade gap is c = (5%-8%) t; for t = 3MM-5MM, the blade gap is c = (8%-10%) t.
For hard materials with a thickness t < 1MM, the blade gap is c = (4%-5%) t; for t = 1MM-3MM, the blade gap is c = (6%-8%) t; for t = 3MM-8MM, the blade gap is c = (8%-13%) t.
Try to avoid designing rectangular punches, as rectangular punches are prone to waste jumping.
For blade widths less than 1.0mm (round holes less than 1.0mm in diameter), for easy processing and improved accuracy, the blades need to be processed separately.
Punches should avoid excessively long and narrow grooves, and sharp corners should be avoided as much as possible. The length of small punches should be kept as short as possible, with appropriate reinforcement added.

Punches should be designed with an anti-stripping structure, considering the reduction of discharge machining.

Design Standards for Forming Components
Standard for the fit clearance of forming punches, standard for the springback parameters of parts with R-angle bending, referring to the “Springback Value Table.” Depending on the hardness of the material, the greater the hardness, the larger the values can be.

Springback Standard for R≤5 Bending
Material	Thickness	Bending Angle
Material	Thickness	＞90°	＜90°	90°	Empty
Stainless steel Phosphor/ Bronze/ Beryllium copper	T＜0.3mm	3°-5°	2°-4°	0.1-0.2°	5°-10°
Stainless steel Phosphor/ Bronze/ Beryllium copper	T＞0.3mm	2°-4°	2°-3°	0.1-0.2°	4°-8°
Iron material/ Bronze/Red copper	T＜0.3mm	1°-3°	2°-3°	0.1-0.2°	2°-4°
Iron material/ Bronze/Red copper	T＞0.3mm	1°-2°	1°-2°	0.1-0.2°	1°-3°

4. Template Block Design and Processing Standards

Precision requirements for template processing: machining tolerances and special manufacturing processes.
For template templates longer than 500mm, split design is required; all molds need to have process reference holes.
The processing accuracy of mold template parts in the whole set is required to be controlled within ±0.01mm, and the surface roughness of the template is required to be less than 0.4um.
For the blanking holes, stacking bodies, and oil cutting of the blanking plate and lower template, all fixed pin holes are treated with JG grinding; the sliding fit clearance C+ (0.005-0.010mm), non-sliding fit clearance C+0.003mm, machining accuracy ±0.002mm.
For the upper template, blanking plate, and lower template, the use of Misumi internal guide pins and guide bushes filled with glue improves guiding accuracy to ensure the positional accuracy of the template during production.
After heat treatment, the template undergoes super-deep cryogenic aging treatment, and some may require stabilization treatment to eliminate internal stress, prevent grinding deformation, and ensure template flatness of 0.005mm.

5. Mold Inspection Requirements

Verify that punches, inserts, dimensions of template length, and thickness conform to the drawing specifications.
Check the condition of screw holes and threading; assess the fit clearance of internal and external guide pillars; inspect for any missed wire cutting.
Measure the thickness dimensions of the template, and a difference of within 0.005mm in four-point measurements is considered acceptable.
Inspect the relinquishment processing status; ensure that the hole diameters and counterbore depths of various template through-holes comply with the drawing specifications.
Examine whether each hole is eccentric, assess the alignment of templates, and check the normality of positioning pins.
Apply chamfering to the periphery of the template. Include mold identification details on the sides, such as mold number, part number, material code, pitch, material width, mold closing height, and other parameters.

6. Mold Assembly Standards

Mold assembly is divided into two parts, upper and lower, assembled separately, and finally, the upper and lower molds are assembled together.
Firstly, understand the mold drawings, product information, analyze the mold structure, and comprehend the design intent of the mold.
Chamfer, polish, engrave, and categorize the templates and parts.
Use specialized positioning tools for installing internal and external guide pins and bushings to ensure their verticality during the positioning and gluing process.
Ensure smooth assembly of punches and block pairs, and appropriate force when tapping parts.

7. Mold Spare Parts Detailed Management

For molds accommodating multiple machine types, each part is assigned a unique number for clear and separate storage. This facilitates efficient replacement during the production process, expedites effective mold assembly, and reduces downtime during the production line changeover.

Figure 1: Spare Part Temporary Storage Area

Parts are systematically arranged for easy visibility and subdivided into spare parts, blade components, machine-specific parts, molding parts, and standard components.

8. Continuously Optimize Part Structures, Validated Parts as Design Standards

Emphasizing technological innovation in designing parts: Figure 1 depicts a symmetric part that, once subjected to bending wear during the production process, becomes unusable. In Figure 2, a design optimization involves disassembling the part and redesigning the bending position as a double-sided molded part. Wear can be mitigated by turning to the other side for forming, effectively reducing processing costs and production downtime.

Conclusion:

In the dynamic landscape of metal stamping, the standardization of molds emerges as a cornerstone for operational excellence. It not only ensures the reliable production of high-quality parts but also positions manufacturers to adapt swiftly to industry advancements. As technology continues to reshape the manufacturing landscape, the role of standardized metal stamping molds becomes increasingly critical in driving efficiency, precision, and overall competitiveness.

Press-Fit Terminals: The Zero-Solder Solution Securing EV Battery Safety

FPIC’s Precision Metal Terminals Redefine Reliability for New Energy Vehicles

In the rapidly evolving world of electric vehicles (EVs) and energy storage systems (ESS), every connection matters. Behind the silent efficiency of a battery pack lies a complex web of conductors, sensors, and signal interfaces — all of which must perform flawlessly under vibration, heat, and extreme environmental conditions.

Traditionally, engineers relied on solder joints to attach sampling wires or signal leads to printed circuit boards (PCBs). However, as vehicles endure long-term vibration and frequent temperature changes, solder points can crack, loosen, or fail — leading to signal interruptions, system alarms, and even vehicle shutdowns.

To eliminate this hidden risk, the industry has embraced a new generation of eyelet terminals (also known as fish-eye terminals) — a zero-solder, press-fit connection technology that has become the benchmark for safety and reliability in modern EV battery systems.

1️⃣ Zero-Solder Technology for Reliable, Long-Term Connections

Eyelet terminals replace traditional soldering with mechanical press-fit technology.
Each terminal is precisely inserted into a plated through-hole on the PCB, forming a gas-tight, cold-welded mechanical bond without heat or solder.

This approach eliminates problems like cold joints, thermal stress, and oxidation, ensuring stable electrical conductivity throughout the battery’s life cycle.
For high-current and high-vibration applications, it offers a proven reliability advantage — meeting the demanding standards of automotive-grade safety.

2️⃣ Optimized Contact Design for Signal Integrity

The terminal’s unique spring-like geometry maintains constant pressure within the hole, minimizing contact resistance and ensuring low temperature rise even under heavy current flow.

By preserving signal integrity in high-load environments, eyelet terminals ensure accurate battery monitoring, voltage sensing, and cell balancing — critical to the safe operation of every EV.

3️⃣ Higher Assembly Efficiency, Lower Manufacturing Risk

Eyelet terminals simplify the manufacturing process by eliminating the need for soldering, flux cleaning, and heat management.
This leads to:
✅ Shorter assembly cycles
✅ Lower defect rates
✅ Improved automation compatibility

For large-scale EV battery production, such as power battery modules and BMS systems, this technology significantly improves throughput, consistency, and process control — perfectly aligning with the industry’s move toward smart manufacturing.

4️⃣ Eco-Friendly Manufacturing for a Sustainable Future

Since no solder or flux is required, press-fit terminal production avoids emissions from solder fumes and reduces waste from cleaning chemicals.
This aligns perfectly with the environmental, social, and governance (ESG) objectives of leading automotive OEMs — supporting green manufacturing and sustainability throughout the supply chain.

5️⃣ Vibration Resistance and Structural Reinforcement

FPIC’s eyelet terminals feature a preformed elastic zone that absorbs vibration and compensates for mechanical stress.
Combined with over-molding technology, this ensures that the terminal remains firmly anchored to the PCB — even under severe vibration and impact.

The result: no loosening, no micro-cracks, and no signal failure, even after tens of thousands of vibration cycles.

6️⃣ Performance in Extreme Environments

Through advanced materials and precision forming, FPIC’s terminals achieve wide temperature tolerance (-40°C to +125°C), excellent corrosion resistance, and stable contact pressure over the product’s full lifecycle.

Whether it’s a fast-charging EV at 125°C, a cold-start at -40°C, or coastal salt-fog exposure, FPIC’s terminals maintain consistent performance and safety.

7️⃣ Full Lifecycle Reliability Testing

Every FPIC eyelet terminal undergoes comprehensive testing in our in-house laboratory, including:

Insertion & extraction force validation
Thermal cycling and vibration endurance
Temperature rise testing
Corrosion resistance & salt spray testing
Dimensional inspection via KEYENCE systems

This ensures each part meets the highest standards of IATF 16949, ISO 9001, and VDA 19.1 for automotive components — guaranteeing full traceability and reliability across the production chain.

8️⃣ Expanding Applications in EV and Energy Storage Systems

From battery module assemblies and power distribution units (PDUs) to on-board chargers and energy storage containers, eyelet terminals are enabling modular, maintainable, and scalable designs for the new energy era.

Their plug-and-play, serviceable design not only enhances system safety but also streamlines assembly, repair, and recycling — providing an ideal foundation for next-generation solid-state and sodium-ion batteries.
