Selection Guide & Product Overview: Capping Machines (Full Series)
1. What is a Capping Machine?
Working Principle A capping machine uses a power source (Electric or Pneumatic) to drive a capping head that generates mechanical torque to tighten caps onto containers. * Friction Capping: Uses a high-speed rotating rubber head to tighten caps via friction (e.g., SGJ-80, SG-1550). * Locking/Rolling: Specifically designed for anti-theft or aluminum caps, using physical side-pressure to lock the ring (e.g., DK-50). * Vacuum Sealing: Extracts air from a sealed chamber before capping to extend food shelf life (e.g., VC-10A). * Crimping/Clamping: Used for perfume pumps or vials to achieve a permanent, tamper-evident seal (e.g., PC-88).
Core Value * Sealing Consistency: Ensures every bottle has uniform torque, eliminating leakage or loose caps caused by manual labor. * Efficiency Scalability: Covers everything from "low-volume lab sampling" to "large-scale factory automation." * High Compatibility: Specially designed heads adapt to pump heads, sprayers, duckbill caps, and other irregular shapes.
Target Industries Widely used in Cosmetics, Daily Chemicals, Pharmaceuticals, Food & Beverage, Lubricant Oil, and Chemical Raw Materials.
2. Core Model Selection Table
Locate the ideal machine based on your production scale, cap type, and automation requirements:
| Automation Level | Recommended Model | Cap Diameter Range | Efficiency | Primary Applications & Cap Types |
|---|---|---|---|---|
| Handheld Portable | SG-1550 | 10-50mm | 20-40 bpm | No bottle height limit; ideal for oversized buckets, heavy containers, or mobile operations. |
| Desktop Semi-Auto | DDX-450 | 10-50mm | 20-40 bpm | Pure electric desktop model; compact structure for standard plastic flat caps. |
| Anti-theft Locking | DK-50 | 20-40mm | 20-40 bpm | Specialty for anti-theft caps (e.g., mineral water, liquor bottles) with pilfer-proof rings. |
| Specialty Cap Expert | SGJ-80/SGJ-70 | 20-70mm | 30-45 bpm | Pump/Spray/Duckbill caps; electric & pneumatic control; excellent stability for odd-shaped caps. |
| Crimping/Clamping | PC-88 | 13-22mm | 20-200 bpm | Perfume/Vials/Oral liquid bottles; pneumatic crimping for a beautiful and airtight finish. |
| Vacuum Sealer | VC-10A/VC-10B | Mold-customized | 0-600 bph | Glass Jars/Condiments; dual-station design ensuring high vacuum levels for food preservation. |
| Automatic In-Line | ASGJ | 18-70mm | 30-45 bpm | Single-head automatic with PLC touch screen; ideal for flexible production lines with various products. |
| High-Speed Auto | ADK | 20-40mm | 45-60 bpm | Multi-head (6 heads std.); includes German SICK sensors; the top choice for large-scale production. |
Note: bpm = bottles per minute; bph = bottles per hour.
3. Technical FAQ & Common Solutions
Q: Both SGJ-80 and DK-50 are desktop models. How do I choose? * A: It depends entirely on the cap structure. SGJ-80 uses friction and is perfect for pump heads or sprayers with long straws. DK-50 uses a mechanical roller to lock the cap ring, designed specifically for rigid plastic caps with "anti-theft break-away rings."
Q: What vacuum level can the VC-10A achieve? * A: When paired with a professional vacuum pump, it can exceed 0.08Mpa. This effectively inhibits aerobic bacteria growth, making it essential for glass jars with tinplate caps (e.g., pickles, bird's nest, jams).
Q: Why choose a handheld SG-1550 over a desktop machine? * A: It is the ultimate solution for spatial constraints. When containers are too large to move (e.g., 20L drums) or too heavy/irregular for a worktable, the handheld unit—supported by a spring balancer—offers unmatched flexibility.
Q: What is the difference between ASGJ and ADK on a production line? * A: ASGJ focuses on "flexibility"; it allows for fast mold changes and is suited for manufacturers with many SKUs and medium batches. ADK focuses on "maximum output"; it features synchronized multi-head capping for mature, high-volume dedicated lines.
4. Customization & OEM/ODM Capabilities
As a specialized manufacturer, we offer deep customization from components to integrated systems:
-
Capping Head Customization:
