Free Stop Programmable Rotary Indexers Reshape Packaging, Pharma and Electronics Assembly Lines
2026/10/28
Fixed Indexing Is Not Always Enough
A fixed cam indexer moves the table by a defined angle, dwells and repeats — extremely well, for millions of cycles. But modern packaging machines, pharmaceutical fill-finish cells and electronics assembly lines increasingly need to stop anywhere on the dial for inspection, labelling, laser marking or robotic pick-and-place, then resume indexing without losing reference position. That requirement made the free stop programmable rotary indexer the fastest-growing family at Hongbang (宏邦) — 55 models in production under the HONEPAN brand.
Five Free Stop Platforms
- DS Series (shaft output) — intermittent conveyor and belt-driven transfer with precise start-stop control
- DF Series (flange-mounted) — wide mounting surface and flange output for heavy dial tooling
- DE Series (flange type) — developed for pharmaceutical mandrel and flange divider applications
- DT Series (hollow shaft, platen) — heavy-load automation with services routed through the table centre
- DA Series (ultra-slim platen) — compact axial height with high precision for constrained cells
For specialised processes Hongbang also builds a compound transmission programmable rotary indexer for nail-making machines and a cam-driven oscillating indexer for reciprocating precision motion, both with free stop design.
Accuracy You Can Audit
| Series | Output | Model Range | Positional Accuracy | Typical Application |
|---|---|---|---|---|
| DS | Shaft | 32DS–200DS | ±30 arcsec | Intermittent conveyor, feeding machines |
| DF | Flange | 45DF–230DF | ±30 arcsec | Disc machining, dial tables |
| DE | Flange | Configured to tooling | ±30 arcsec | Pharmaceutical fill-finish |
| DT | Hollow shaft | 110DT–140DT and above | ±30 arcsec | Heavy-load platen automation |
| DA | Ultra-slim flange | Custom | ±30 arcsec | Height-restricted cells |
Repositioning accuracy reaches ±4 arcsec as standard and ±2 arcsec on customized builds, cam hardness runs HRC 50–72, and rated longest life is 60,000 hours. The 45DF customizable drive is supplied with full OEM support so builders can carry their own branding and documentation.
Industries Driving Demand in 2026
Packaging automation in Turkey, Poland, Mexico and the United States; pharmaceutical and medical device lines in Germany, Switzerland and Italy; electronics and semiconductor assembly in Vietnam, Malaysia and India; automotive welding positioners where free stop programmable rotary index tables replace hydraulic clamping fixtures.
Why the Brand Behind the Number Matters
An indexer failure stops an entire line, so specification quickly becomes a credibility conversation. Hongbang Automation Machinery Factory (宏邦, brand HONEPAN) answers with facts rather than adjectives: established January 2007, 120–180 employees, 30,000+ customers served, 20%–30% of output exported, annual sales of RMB 70–130 million, ISO 9001 certification, one-year warranty, 5,000 sets per month of supply ability and a 4–20 day delivery window on T/T terms.
Hongbang also manufactures the cams themselves — cylindrical, globoidal, grooved, face and special-shaped — plus non-standard cam mechanism sets, cam assembly structures and, for rotary tables, technical selection of motor reducers. That vertical control is why a free stop design can still hold ±30 arcsec after extended programmable cycling instead of drifting once the cam profile wears.
