NEV Parts Riveting Case: Efficiency Gains from Blind Riveting Battery Boxes and Structural Parts - BISUDI

Published: 2026-09-17 10:00:00 Views: 6 views Author: admin

Domestic new-energy vehicle manufacturing bases are highly automated, yet many component makers and tier-2 suppliers still rivet by hand. Using an anonymized case, this article explains the efficiency logic of switching battery boxes and structural parts to automatic blind riveting.

I. Riveting pain points of component makers

Battery boxes, battery-pack accessories, seat frames and body stampings have many points and high consistency requirements; manual blind riveting carries a high risk of night-shift missed rivets, and data cannot be traced, making it hard to pass OEM system audits; aluminum parts also require deformation and sealing control.

II. Retrofit solution and data

Item	Before Retrofit	After Retrofit
Missed rivets at key points	Visual inspection, occasional on night shift	Point counting and incomplete prompts, down to zero
Single-line labor	4 riveting workers	2 minding the machine + patrol inspection
Data traceability	No records	IO to PLC/MES, points queryable
Aluminum-part quality	Variable deformation and scratches	Fixture + scratch-proof nozzle, consistency improved

III. Sealing and pulling-force verification

Battery boxes use a combination of structural adhesive, seal rings and blind rivets/rivet nuts; during the trial, overall pull-out and sealing verification is done by section and plate thickness; mass-production trays are advised to use robotic/gantry stations, and seat frames etc. use in-line counting dual-gun models.

Anonymized case: a new-energy auto-parts maker

After introducing a robotic riveting station and an in-line counting dual-gun riveting machine, missed rivets at key points of battery boxes and seat frames fell to zero, data became traceable, single-line labor dropped by about half, and the plant passed the OEM system audit and took on new orders.

IV. Advice for suppliers

Pilot at the most critical, most strictly audited station first, bring a machine for on-site sampling to obtain cycle, pulling-force and missed-rivet data, then replicate in batches to avoid the risk of a one-off large investment.

FAQ

Q1: Can it connect to the OEM's MES?

In-line and robotic models provide IO signals and counting data, and can connect to PLC/MES per the customer's system for error-proof traceability.

Q2: How is waterproofing of battery parts guaranteed?

Through a combination of sealing rivets, rivet nuts, structural adhesive and seal rings, with sealing verification per the battery-box process during the trial.
