Production Process of New Energy Fuse Copper Cap and Copper Contact
1- Stamping Process
(1.1)Material Preparation:

High-quality copper material is used to ensure it meets production requirements and product standards.
The copper material for Fuse Copper Cap, Fuse Copper Contact, and Fuse Copper Terminal must meet specific chemical composition and mechanical performance requirements.

(1.2)Mold Design and Manufacturing:

Design and manufacture stamping dies according to product design requirements.
The molds should have high precision and stability to ensure the production of caps and contacts that meet dimensional requirements.

(1.3)Stamping Forming:

Place the copper material on the press and form it using the molds.
Stamp the Fuse Copper Cap to create a cap structure suitable for the fuse.
Stamp the Fuse Copper Contact to create a conductive contact structure.

(1.4)Positioning and Inspection:

Ensure accurate mold positioning during stamping to avoid dimensional deviations or shape distortion.
Inspect the stamped caps and contacts for dimensions and appearance to ensure their quality meets requirements.

2-Soldering Process
(2.1)Preparation:

Prepare soldering equipment, including soldering furnace, soldering table, solder wire, etc.
Additional preparation of soldering materials is required for the production of Fuse Copper Terminal.

(2.2)Surface Treatment:

Clean the surfaces of caps, contacts, and terminals to ensure no oil, oxide, or other impurities are present.
Polish the caps and contacts to improve the surface flatness and cleanliness for soldering.

(2.3)Soldering Operation:

Position the Fuse Copper Terminal at the specific location on the cap and fix it using solder.
Ensure proper temperature and soldering time control during the soldering process to prevent overheating or inadequate soldering.

(2.4)Quality Control:

Inspect the appearance and soldering strength of the soldered components to ensure soldering quality meets standard requirements.
Promptly adjust and address any issues that arise during the soldering process to ensure product quality and stability.
