Cylindrical Battery Grooving Machine: Precision Equipment Empowering High-Quality Battery Production

In the booming global battery market—where cylindrical batteries dominate applications from consumer electronics (smartphones, laptops) to electric vehicles (EVs) and stationary energy storage—every manufacturing step directly impacts product performance, safety, and scalability. Among these critical steps, the grooving process of cylindrical battery casings stands out: it creates precise grooves to secure internal components (like jelly rolls) and ensure hermetic sealing, preventing electrolyte leakage and short circuits. Addressing this demand, AOT’s Cylindrical Battery Grooving Machine MSK-500B emerges as a versatile, high-precision solution tailored for both industrial production and laboratory R&D, bridging flexibility and reliability for modern battery manufacturers.

1. Product Overview: Targeted for Cylindrical Batteries & Supercapacitors

The AOT-MSK-500B is a specialized grooving device designed explicitly for the cylindrical battery and supercapacitor manufacturing workflow. Its core mission is to deliver consistent, accurate grooves on metal casings—an essential prerequisite for assembling battery cells that meet strict industry standards.

Out of the box, the machine comes equipped with a standard 18650 groove rolling mold—one of the most widely used cylindrical battery formats in consumer electronics. However, its true strength lies in customization: by replacing the groove rolling mold, it can process cylindrical batteries and supercapacitors with an outer diameter range of 10mm to 50mm and a length range of 20mm to 140mm. This covers popular industrial models like 21700 (EV-grade), 3260 (energy storage), and 4680 (large-format EV batteries), making it a one-stop solution for manufacturers handling multiple product lines.

2. Core Functional Features: Precision, Flexibility, and Adaptability

The MSK-500B’s design prioritizes user-friendliness, process stability, and compatibility with diverse production environments—key pain points for battery manufacturers. Below are its standout features:

2.1 Adjustable Groove Sizes for Consistent Quality

Battery casings require grooves with tight dimensional tolerances: too shallow, and components may shift during cycling; too deep, and the casing’s structural integrity weakens. The MSK-500B addresses this with adjustable groove depth (0.8–2.0mm) and customizable groove width (standard 1.2mm, range 0.9–1.5mm). Its mechanical structure minimizes vibration during grooving, ensuring groove size variation stays within ±0.05mm—critical for avoiding electrolyte leakage or internal short circuits in high-energy-density batteries (e.g., 4680 cells).

2.2 PLC Touchscreen: Intuitive Operation & Parameter Storage

Gone are the days of manual knob adjustments that risk human error. The MSK-500B integrates a PLC touchscreen control system, allowing operators to set, store, and recall grooving parameters (e.g., pressure, speed, groove dimensions) with a few taps. This not only reduces training time for new staff but also ensures consistent process settings across shifts—essential for large-scale production where batch-to-batch uniformity directly impacts yield.

2.3 Mold Compatibility for Multi-Spec Production

For manufacturers or R&D labs working with diverse cylindrical formats, the MSK-500B eliminates the need for multiple dedicated machines. Its quick-change mold system enables seamless switching between battery sizes (e.g., from 18650 for laptops to 4680 for EVs) in minutes. This flexibility is particularly valuable for small-to-medium enterprises (SMEs) and research institutions, where production volumes vary and prototyping of new battery formats (e.g., sodium-ion cylindrical cells) is common.

2.4 glove box Compatibility for Inert Environment Processing

Many advanced battery chemistries—such as lithium-metal batteries or high-nickel cathodes—require processing in an inert environment (e.g., argon-filled glove boxes) to prevent material oxidation. The MSK-500B supports this via a transition chamber with an inner diameter >360mm, allowing it to be integrated into glove box systems. This expands its application to high-value battery R&D and production, where environmental control is non-negotiable.

3. Key Technical Parameters: Performance Backed by Data

The MSK-500B’s technical specifications are engineered to balance performance, durability, and adaptability to real-world manufacturing conditions:

Notably, the machine’s gas pressure settings are pre-calibrated at the factory to suit 95% of common steel shells—minimizing trial-and-error for manufacturers and reducing scrap rates. For special cases (e.g., stainless steel casings for high-temperature batteries), on-site pressure adjustment is straightforward, ensuring process flexibility.

4. Applicable Scenarios: From Mass Production to Lab R&D

The MSK-500B’s versatility makes it a valuable tool across multiple segments of the battery industry:

4.1 Cylindrical Battery Manufacturers

For companies producing batteries for EVs (21700, 4680), consumer electronics (18650), or energy storage (3260), the machine’s multi-spec compatibility eliminates the need for separate grooving equipment. Its high precision ensures consistent casing quality, which directly reduces post-assembly defects (e.g., electrolyte leakage, poor contact between components).

4.2 Supercapacitor Producers

Supercapacitors—used in regenerative braking systems and backup power—often share cylindrical form factors with batteries. The MSK-500B’s ability to process non-battery cylindrical casings makes it a cross-application solution for manufacturers with mixed product lines.

4.3 Battery R&D Laboratories

Academic institutions and corporate R&D teams testing new cylindrical battery chemistries (e.g., lithium-sulfur, sodium-ion) benefit from the machine’s customizable molds and glove box compatibility. It supports small-batch prototyping while maintaining the same precision as industrial-scale equipment, ensuring lab results translate reliably to mass production.

5. Why Choose the AOT-MSK-500B? Industry Pain Points Solved

Battery manufacturers face three core challenges in grooving: inconsistent quality, limited format flexibility, and high maintenance costs. The MSK-500B addresses these head-on:

Quality Consistency: PLC-controlled parameters and stable mechanical design reduce groove size variation to ±0.05mm, cutting rework rates.

As the cylindrical battery market grows—driven by EV adoption and energy storage demand—precision and flexibility in manufacturing equipment become non-negotiable. The AOT-MSK-500B Cylindrical Battery Grooving Machine stands out as a solution that balances these needs, supporting both industrial-scale production and cutting-edge R&D. Its adjustable settings, mold compatibility, and glove box integration make it a versatile asset for manufacturers aiming to stay competitive in a fast-evolving industry.

For businesses seeking to enhance battery casing quality, reduce costs, and adapt to new product formats, the MSK-500B is more than a grooving machine—it’s a strategic investment in reliable, scalable battery production.
