Manufacturing Equipment Stainless Steel Fabrication Of Internal Isolation Membrane Of Electric Vehicle Batteries

Our custom stainless steel piping components for electric vehicle (EV) battery separator equipment are precision-manufactured according to customer drawings, with excellent corrosion resistance, airtightness and dimensional accuracy. We use advanced CNC laser cutting, bending forming, turret punching and TIG/MIG welding technology to ensure ±0.1 mm tolerance and hygienic surface treatment, which is very suitable for demanding cleanroom integrated production lines.
Overview
We specialize in custom sheet metal manufacturing and can convert your CAD files (STEP/DWG/PDF) into high-precision stainless steel parts for EV battery separator machines.
. Our components (such as pipes, manifolds and housings) are an important part of wet and dry separator coating and drying processes, ensuring uniform airflow and temperature control during film formation and curing.
Main Features
I. High-quality materials

Made of SUS304 or SUS316L stainless steel, it has excellent chemical stability and corrosion resistance in humid and high temperature environments.
.

II. Precision cutting and forming

CNC laser cutting can produce complex profiles with burr-free edges for perfect assembly.
.

Press-bend forming allows for consistent bends and shapes up to 6 meters long with a repeatability of ±0.1 mm.
.

Turret punching allows for precise hole patterns and slots to be made to customer specifications.
.

III. Seamless Welding

TIG/MIG welding performed by certified welders ensures full penetration, crack-free, and leak-proof seams, which is critical to maintaining controlled airflow and pressure.

IV. Surface Treatment

Options include 2B calendering, No. 4 brushed, and electro-polished surfaces to meet cleanroom standards and minimize particle generation.
.

V. Customization and Flexibility

We manufacture elbows, reducers, flanges, and complex multi-piece assemblies to your exact drawings to meet all the shapes and sizes required for your electric vehicle partition production line.
