Scrap Suction Unit for Stamping Press Slug Removal
A HENLI scrap suction unit, also described as a punch press scrap vacuum unit, helps collect small, separated slugs and chips near the stamping die. Selection depends on the scrap sample, production rate and suction layout.
Compare the XF series, press-side arrangements and collection options to specify a scrap removal system around your tooling and production needs.
How the scrap suction unit works 45-second demonstration
Illustrative 3D demonstration of an XF-3P scrap suction unit with silencer.
A sealed cabinet with the blower on top
The integrated XF unit is one compact machine: the ring blower sits on the collection cabinet, and the cabinet rolls on casters beside the press. Open the front door and the collection bin lifts straight out.
- Ring blower on top. It draws the suction airflow through the cabinet; an exhaust silencer is available.
- START / STOP starter. Mounted on the cabinet top beside the blower.
- Sealed collection cabinet. The door seals with a gasket and closes with two toggle latches.
- Removable collection bin. Lift it out through the front door to empty it.
- ร60 mm inlet and steel-wire hose. The standard 3 m (9.84 ft) hose runs to the pickup at the die.
- Casters. Roll the unit into place beside the press.
Match the system to your waste stream. Suction is suitable for small, separated stamping scrap when its size, weight, output and pickup route are compatible with the selected unit. Continuous strips, large skeletons and oversized offcuts typically need chopping, recoiling or mechanical conveying. Compare the methods below.
Select the right scrap removal method
Start with the scrap form and outlet arrangement. Suction, chopping and conveying solve different handling problems.
Small slugs and chips
Use suction where the scrap sample and pickup route are suitable. Collection close to the outlet can help limit accumulation around the die.
Strip and skeleton scrap
Consider a scrap chopper or scrap strip recoiler for continuous waste. Do not feed long, tangled skeleton scrap into a standard suction pickup.
Conveyor or shaker handling
A mechanical transfer system may suit other scrap forms or under-press layouts. Compare the material, volume and route before choosing the equipment.
Scrap evacuation does not replace die maintenance or correction of slug pulling. Fine dust, combustible dust and liquid collection require a separately assessed system.
Split and integrated configurations
The distinction is whether the blower and scrap collection cabinet are separate or assembled as one machine. Both configurations use hoses; their positions are selected around the stamping press and die outlet.
Split-type scrap suction system
The scrap collection box and blower are separate components. The box can be placed beneath the stamping press or near the die outlet, with a hose connecting it to the blower in a separate position.
Integrated scrap suction unit
The blower is mounted on the scrap collection cabinet, forming one machine. The unit stands beside the stamping press, with a suction hose connecting the die scrap outlet to the collection cabinet.
Scrap suction unit specifications
Compare the listed standard models in metric or US customary units. The final configuration must be checked against your scrap sample, electrical supply and suction route.
Standard units and silencer variants
Compare the existing product configurations. A silencer is an option to address exhaust noise; the required model still depends on the operating duty.
XF-3P
2.2 kW listed motor power; shown in standard and silencer configurations.
XF-5P
3.7 kW listed motor power; compare the collection-box and exhaust arrangements.
XF-7.5P
5.5 kW listed motor power with a 550 x 550 x 550 mm tank size.
XF-10P
7.5 kW listed motor power. Confirm pickup geometry and scrap duty rather than selecting by power alone.
Variable-frequency and weighing options
Specify the controls and collection functions your line needs. Availability and operating limits are confirmed for the quoted configuration.
Variable-frequency control
Adjust suction within the approved motor and blower range for the application. Confirm control method, required interfaces and operating settings with the project configuration.
Weighing-type collection
A collection-weight display supports checking collected scrap. Required capacity, accuracy, units and any alarm or control interface must be specified for the quotation.
Larger units and automatic scrap discharge
These configurations extend the range of project discussions. Their specifications and interfaces are confirmed separately from the six standard models above.
XF-20P configuration
Discuss the actual scrap load, route and collection requirements for a larger unit. Request a project-specific specification sheet rather than extrapolating from the standard table.
Automatic scrap discharge
Discuss an automatic dumping arrangement when the line requires a different collection and emptying workflow. Confirm discharge destination, access and safety interlocks for the complete installation.
How the scrap suction system works
A pickup funnel and hose connect the die outlet to the collection path. The layout must be tested with the intended scrap and production conditions.
Collect at the outletPosition a suitable funnel near the die scrap outlet to capture the intended waste stream.
Connect the suction routeRoute the hose with suitable supports and service access. Avoid unnecessary length and sharp bends.
Establish the airflowThe blower draws air through the approved pickup and collection path.
Separate and collect scrapScrap enters the collection box while the specified separation and filter arrangement protects the airflow path.
Check under production conditionsConfirm collection with representative scrap at the intended production rate; check for accumulation and leakage.
Empty and inspect safelyStop and isolate the machine before opening, clearing or servicing it, following the supplied instructions.
Watch the real-world suction demonstration
See the equipment and press-side installation in real footage. The 3D animation above explains the collection principle; actual scrap and pickup layouts vary.
Custom funnels and hose routing
The pickup should match the scrap outlet and permit safe operation, die changes and cleaning. Provide outlet photos and dimensions before the mounting arrangement is finalized.
Overhead pickup
Assess the available space above the scrap path and whether the intended pieces can be captured without interfering with the tooling or operators.
Press-mounted support
Position and support the funnel around the outlet while retaining access to guarding and service points. Agree the mounting method with the press owner.
Die-side connection
Consider a tooling-side connection only where the die design allows it. Do not drill, obstruct vents or change the approved airflow path without engineering review.
Reduce unintended leaks at joints while preserving the designed airflow openings. Include hose length, lift, bends and pickup count in the selection review.
Scrap collection around stamping lines
These existing application photos show different installation contexts. Suitability still depends on the actual scrap sample and the specified separation and collection arrangement.
Lead-frame stamping
Review the small scrap geometry, production rate and die outlet when specifying collection near a precision stamping process.
Punch press installation
Match the unit location and pickup route to the available press-side space and collection-box access.
Button and eyelet deep drawing
Coolant-bearing or oily scrap needs a separate assessment of separation and collection. The application photo does not establish a liquid-vacuum rating.
Other machine-side collection
Discuss suitable discrete chips separately. Fine grinding dust and slurry require purpose-specified extraction and separation equipment.
Keep the scrap path accessible
Allow room to inspect the hose, collection box and filtration arrangement. Inspection frequency should reflect scrap output and the supplied operating instructions.
Routine checks
- Check the required power supply and approved rotation or airflow direction during commissioning.
- Monitor collection level and remove scrap before it obstructs the collection path.
- Inspect the filter, hose and funnel for loading, damage, blockage and unintended leaks.
- Stop for abnormal vibration, unusual noise, overheating or a significant loss of suction.
- Isolate power before opening, clearing or maintaining equipment; follow the supplied manual.
