Inside the unit
Fixed drive boxes, a moving rail frame and trays
Each F-series shaker is one compact electric unit: two drive boxes fixed to the press, one cross shaft linking them, and aluminium rails that carry the trays back and forth. The model number is the machine length in millimetres, from F-800 to F-3000.
- Gear motor and speed control. A gear motor turns the cross shaft; a knob on the control box sets the conveying speed.
- Two fixed drive boxes. They bolt to the press or a stand, and one cross shaft links them so both ends move together.
- Aluminium rail frame. T-slot aluminium rails form the moving frame that carries the trays.
- Trays to suit the press. One or more trays mount on the rails and reach under the die or out to the collection point.
- Electric, no compressed air. The standard power supply is 220 V or 380 V.
Tray size, mounting and discharge position are matched to your press opening, scrap and collection point.

Product position
A Low-Profile Scrap Route between the Die and Collection Point
This machine is a press scrap shaker or shaker-tray conveyor for punch presses and stamping presses. It is also known as a punch press scrap shaker, stamping press scrap shaker, electric shaker conveyor, oscillating scrap conveyor, shuffle conveyor or scrap transporter. It is not a vibratory bowl feeder, metering feeder, belt conveyor or pneumatic suction unit.
What the machine is designed to do
A tray or chute receives loose material below the die, at the press end or beside a scrap opening. Reciprocating motion advances that material toward a bin, bag or downstream conveyor. The tray carries the scrap; the drive creates the transport motion.
The compact, tray-based route fits areas where a conventional belt conveyor is difficult to install, so the shaker can serve as a low-profile press scrap conveyor for die scrap removal. It also offers a practical way to upgrade scrap removal around an existing punch press or stamping press without rebuilding the complete production line.
HENLI waste-handling position: use this shaker for loose material collected in trays. Choose scrap suction for suitable light loose scrap, a scrap chopper for continuous skeleton, or a strip recoiler when continuous strip must remain in a roll.
Working principle
How the Reciprocating Tray Moves Scrap Forward
The electric drive produces a controlled reciprocating cycle: the tray advances the material during one part of the stroke and returns quickly to limit material carry-back. Repeated cycles create continuous movement toward the discharge point. This slip-stick or โtablecloth effectโ conveying uses a reciprocating stroke rather than high-frequency vibration, so the shaker is a linear-motion conveyor, even though some buyers search for it as a vibratory scrap conveyor.
Receive.
Slugs, trim or small parts drop onto the tray near the die outlet.
Advance.
The tray moves in the discharge direction and carries material forward.
Return.
The return portion of the motion limits backward travel of the material.
Discharge.
Material leaves the tray into a bin, bag, belt conveyor or another verified collection device.
SPM is not a one-to-one speed setting. Size the shaker from maximum scrap mass per press stroke ร maximum press SPM, peak accumulation, tray friction, transfer joints and the downstream collection capacity.
Machine structure
Electric Drive, Linked Cross Shaft and Tray Rails
The motor and reduction assembly drive a guided reciprocating frame, and the linked cross shaft (often called the crossbar) distributes the motion to one or more trays, pans or chutes.
Motor and Reduction Assembly
Provides steady electric power for the reciprocating conveying motion.
Linked Moving Frame
Distributes the reciprocating motion across single- or multiple-tray positions.
Tray Rails and Connections
Connect the moving frame to trays or chutes arranged around the press scrap outlets.
Installation positions
Under the Press, at the Press End or beside the Die Outlet
The correct location is the one that creates a continuous downhill or near-level material path without contacting the press, die, guards or service access.
Installation
Recommended Installation and Commissioning Sequence
The compact electric structure simplifies installation because it does not require a compressed-air supply. Follow the press layout, tray path, electrical and guarding steps below.
Survey the press.
Record openings, bolster/T-slot or floor mounting points, stroke clearances, die-change access and discharge height.
Define the tray route.
Confirm pickup points, tray length/width, joints, slopes, sidewalls, scrap size and final collection point.
Check moving mass.
Add tray, brackets, moving cross members and maximum in-process scrap; do not rate the drive from scrap weight alone.
Mount and level.
Secure the approved mounting or stand, level the drive body and provide independent support where long trays require it.
Connect and guard.
Use the project electrical diagram, isolation device, cable protection, interlock strategy and guards for moving parts.
Commission progressively.
Jog empty, test with sample scrap, then verify full production at maximum SPM and worst-case material conditions.

How to read the table: material thickness and scrap width are the scrap sizes each model is configured for, from thin-gauge 0.2 mm up to 3.0 mm thick. The standard power supply is 220 V or 380 V; for any other voltage, send your local voltage, phase and frequency with the inquiry.
Tray and load
Balance the Trays and Support Long Runs
Tray geometry is part of the conveying systemโnot a passive accessory. Poor balance, flexing, interference or rough transfer joints can turn a sound drive into an unreliable installation.
Distribute load around the drive centerline.
Arrange parallel trays and scrap streams as evenly as possible on both sides.
Keep the moving path free.
Allow the full stroke at tray joints, guards, press openings and collection containers.
Support without restraining.
Long trays may need independent low-friction support, but supports must not drag or bind during reciprocation.
Test the real scrap.
Oil, sharp edges, nests and irregular shapes change friction and bridging behavior; sample trials are more reliable than appearance alone.
Why balance matters: an off-center tray load can twist the moving structure and increase stress at the drive, bearings, connections and supports. It also promotes uneven travel, fastener loosening and tray contact.
Applications
Suitable Scrap, Parts and Stamping Environments
Use the shaker where loose material can slide or advance in a tray and where a short, low-profile horizontal route is more practical than elevation or long-distance conveying. In terminal and connector stamping, for example, copper slugs and trim are shaken along the tray and discharged straight into a jumbo bag beside the press.
Slugs and Small Offcuts
Separated slugs, piercings and trim pieces from punch presses running progressive or transfer dies, after sample behavior is checked.
Small Stamped Components
Selected finished parts that can tolerate tray contact and do not require orientation or precision metering.
Existing Press Cells
Older presses can be evaluated where openings, supports, electrical supply, guards and service access permit a tray route.
Parallel Scrap Streams
More than one tray can be linked into one scrap shaker system to collect separate streams when total moving mass, cross-shaft length and balance are approved.
Usually not the first choice: very heavy or oversized scrap, steep elevation, long-distance plant transfer, continuous tangled skeleton, sticky sludge, precision part orientation, abrasive high-temperature material, or a corrosive/washdown environment without a specifically approved build.
Waste-route comparison
Scrap Shaker vs Suction, Chopper, Recoiler and Other Conveyors
Choose from the physical form of the scrap, the distance and elevation, whether the material must stay continuous, and how it will be collected downstream.
| Equipment | Best-fit material and route | Main advantage | Selection limit |
|---|---|---|---|
| Electric scrap shaker | Loose slugs, trim or small parts on a short tray route below or beside the press. | Low-profile, beltless tray movement; practical retrofit candidate. | Tray mass, balance, support, friction and discharge geometry must be verified. |
| Pneumatic scrap shaker | Loose slugs, trim or small parts on a similar short tray route, in plants with a suitable compressed-air supply. | Simple air-powered drive that is widely used on presses. | Needs compressed air of suitable quality and pressure; air consumption, exhaust noise and air-preparation maintenance must be planned. |
| Scrap suction unit | Suitable light loose slugs or chips that can travel through a suction hose. | Flexible pickup and enclosed transfer path. | Not every oily, large, sharp or heavy scrap shape is suitable for suction. |
| Scrap chopper | Continuous strip skeleton that must be cut into shorter pieces. | Reduces continuous skeleton for bin handling. | Blade, width, thickness, material and feed-path selection are critical. |
| Metal strip recoiler | Continuous strip that should remain intact and be collected as a roll. | Controlled roll collection instead of loose scrap. | Requires suitable strip continuity, tension path, roll/core and speed data. |
| Belt conveyor | Longer horizontal routes or general mixed material within the belt design. | Continuous carrying surface and flexible length. | Needs belt tracking, return clearance, cleaning and guarding. |
| Magnetic conveyor | Ferrous material where magnetic retention helps movement or elevation. | Can retain ferrous scrap on inclined or enclosed paths. | Not suitable for non-ferrous material; residual oil and shape still matter. |
Operation and maintenance
Straightforward Daily Checks for Reliable Scrap Flow
The electric, beltless conveying layout eliminates pneumatic air-preparation tasks and conveyor-belt tracking. Routine care focuses on the tray path, connections and drive condition.
Inspect the Route
- Clear accumulated scrap and foreign objects.
- Check trays, joints, guards, cables and collection containers.
- Confirm the full stroke has no contact point.
Watch the Material Flow
- Look for carry-back, bridging, side drift or overflow.
- Listen for new impact, rubbing or loose-fastener noise.
- Verify that the downstream bin or conveyor can keep up.
Follow the Maintenance Manual
- Check mounting and moving connections for looseness or wear.
- Inspect guide, bearing, reducer and seal condition.
- Lubricate and replace wear parts according to the supplied manual.
Troubleshooting
Common Scrap-Flow and Installation Checks
| Symptom | Check first | Corrective direction |
|---|---|---|
| Scrap advances slowly or moves backward | Tray angle/surface, oil, actual scrap shape, moving mass, motion setting and tray interference. | Remove interference, restore the recommended setup and retest with representative scrap. |
| One tray moves unevenly | Off-center loading, bent tray, loose connection, cross-shaft alignment and support drag. | Rebalance the layout, correct alignment/support and tighten only to the specified torque. |
| Scrap jams at a joint or outlet | Step, gap, narrow outlet, hooked pieces, full container or downstream stop. | Smooth the transition, remove the blockage under lockout and provide adequate discharge clearance. |
| Noise or vibration increases | Tray contact, loose fasteners, guide/bearing condition, foundation or scrap impact. | Stop and inspect before continued operation; isolate the equipment before entering the moving area. |
| Motor overload or unexpected stop | Jam, excessive moving mass, mechanical binding, voltage and protection settings. | Lock out, clear the cause and verify the electrical/mechanical ratings before restart. |
Safety
Guard Reciprocating Motion and Isolate Energy before Service
The tray, cross members and linkages create moving pinch, shear and struck-by hazards. The shaker must be included in the press cell's risk assessment and energy-isolation procedure.
Guard the Moving Zone
Prevent access to tray edges, cross shafts, linkages and gaps between moving and fixed structures while the machine can run.
Lock Out before Entry
Stop the press and shaker, isolate all relevant energy sources, verify the zero-energy state and secure moving parts before cleaning, unjamming or service.
Validate the Complete Cell
Confirm emergency stops, restart prevention, interlocks, electrical protection, cable routing and safe bin replacement for the final installation.
