WHERE IT GOES WRONG
The cost shows up later
On a medical or aseptic line, parts feeding is usually where flexibility dies.
A vibratory bowl sheds particles as it shakes, so it gets exiled to a room outside the isolator and the cell loses its in-line flexibility. The fallback, hand-feeding through glove ports, works until volume climbs, then it caps your rate. And a tooled feeder built for one part means a hardware swap every time the part changes, which turns high-mix production into constant downtime.
For most medical-device and cleanroom lines, one question decides the feeder: can it run inside the cleanroom? That matters more than speed or part size, and most feeding advice skips it.
HOW TO CHOOSE
Match the technology to the job
There’s no single right feeder. The right one falls out of the application:
- High volume, one part, no cleanroom → a vibratory bowl feeder wins on cost and throughput.
- Feeding screws into a driver → step feeding matched to the screwdriving head. (Weber.)
- High mix, small or fragile parts, frequent changeovers → flexible feeding earns its premium, because format changes move from hardware into software. (Asyril, FlexiBowl by ARS.)
- Inside a GMP Annex 1 isolator → a feeder engineered specifically for aseptic entry. This lane didn’t exist a couple of years ago.
The first three are well-trodden. The fourth is the new one, and the pressure behind it is real: GMP Annex 1 reached enforcement in August 2023, and flexible feeders built for aseptic isolators went from prototype to production in the same window.
A feeder that can live inside the isolator has to clear a specific bar. It fits through the 190 mm Rapid Transfer Port. It’s built from sterilizable stainless and titanium and rated IP65 for wash-down, so it’s cleaned in place instead of pulled out. It changes format in software instead of hardware. And it’s engineered to the standard rather than retrofitted to it, so your quality team starts from a unit built for the requirement. The one purpose-built for this today is Asyril’s Asycube Clean 230, which Asyril introduced in 2025 as the first flexible feeder built for GMP Annex 1: it fits a 190 mm RTP, is classified to ISO 5, and handles parts from 5 to 40 mm.
And when flexible feeding is the wrong call, we’ll say so. High-volume single-part lines are cheaper and faster on a dedicated bowl. Outside a cleanroom, you don’t need to pay for aseptic-rated construction. Spec the tightest feeder that covers the task.
Outside the cleanroom, the same two mechanisms cover ordinary high-mix work, and that lane has its own page: flexible feeding.

WHY M6
One source, sized to the application
M6 is a single source across every feeding type, so you get the feeder that fits, and a straight answer when flexible isn’t it. We’re factory-backed and local: the team that helps you spec it installs it and supports it, with the manufacturer’s engineering behind us.
You leave knowing exactly which feeder fits your part and your environment, bowl, step, flexible, or cleanroom-flexible, and why, before anyone quotes you a thing.
WHAT WE CARRY
The lines we rep for this application
- Asyril: flexible feeding for small, high-mix, and aseptic parts (the Asycube line, including the cleanroom-rated Clean 230).
- FlexiBowl by ARS: flexible feeding for high-throughput lines with frequent part changes.
- Weber: step feeding matched to automated screwdriving.

THE COST OF WAITING
An automation project gets approved with two numbers
One is the equipment quote. The other is what doing this by hand costs you every month, and only you can add it up:
Labor on the task. Hours per shift, at your fully loaded rate.
The rate ceiling. What the manual step caps your throughput at.
Scrap and rework. What manual variation costs you per thousand parts.
Changeover. Time lost every time the part changes.
The hiring problem. Turnover, training, and the weeks the job sits open.
Exposure. Repetitive lift, pinch points, and what one recordable costs you.
We will get you the equipment number and a budget range early, so your request goes up with both.
COMMON QUESTIONS
Common questions
Can a flexible feeder run inside an aseptic isolator?
Yes, if it’s engineered for it. A cleanroom-rated flexible feeder enters through a 190 mm RTP, is built from sterilizable stainless steel and titanium, is IP65-rated for wash-down, and changes part format in software. A standard flexible feeder usually can’t meet the aseptic-entry and cleaning requirements.
Does flexible feeding meet GMP Annex 1?
A general-purpose flexible feeder doesn’t. A unit engineered for GMP Annex 1 does, such as the Asycube Clean 230 that Asyril introduced in 2025, built to ISO 5 particle classification so qualification starts from a purpose-built unit rather than a retrofit.
When is a bowl feeder still the better choice?
High-volume, single-part, non-cleanroom production. The bowl wins on cost and throughput when the part doesn’t change and particle generation isn’t a constraint.
