Cold forging and header oil smoke extraction
Cold headers and formers run neat-oil lubricant at high stroke rates, and every blow pushes oil smoke off the die area. Share your machines, lubricant and layout so extraction can be matched to the duty.
Every stroke adds smoke to the shop air
Cold heading and cold forging shape metal at room temperature under heavy load, and the lubricant film on wire, dies and parts turns to smoke at each blow. Fastener shops run headers continuously, so the smoke builds into a haze that settles as an oily film on machines, floors and stored parts. Without capture at the die area, operators work inside that haze for the whole shift.
A straight-oil smoke duty
Listed ESP application
The Cleanmist ESP series brochure lists cold heading under its straight-oil machining applications, with hobbing, broaching, thread rolling and deep-hole drilling. Electrostatic cells capture the sub-micron oil particles and drain the recovered oil.
Not a coolant-mist duty
Headers run neat oil, not water-mix coolant, so this is a smoke duty rather than the mist duty the CM series covers. Confirm the lubricant before choosing.
Open and enclosed machines
Older headers run open; newer machines carry covers and guarding. Smoke escapes at openings and at every door-open between setups, so capture belongs at the die area or over the enclosure.
Continuous duty
Headers run long shifts at high strokes per minute. Extraction has to keep up with continuous emission, not a per-cycle burst.
Choosing the extraction arrangement
The ESP series covers ESP1000 (rated 1000-1500 CMH, 250 W), ESP2000 (2000 CMH, 430 W) and ESP4000 (4000 CMH, 770 W), on a 220-240 V single-phase supply with 99% filtration efficiency. These are collector ratings from the brochure, not confirmed airflow requirements for any specific header or former.
At the die area
A pickup arranged over the die zone or connected to the machine cover captures smoke where it forms. Send photos of the die area, covers and the space above the machine.
Per-machine or shared
One ESP per machine suits machines on different patterns. A row of headers on similar duty can share a ducted arrangement when airflow is planned for the combined load.
Washable cells
ESP collecting cells are washed and reused; the standard configuration uses no disposable filter media. A washable metal-mesh pre-filter catches larger droplets, and the optional HEPA after-filter is a separate replaceable element.
Recovered oil
Electrostatic collection drains the captured oil for handling per your shop's practice, instead of loading it into throwaway media.
What to send us before choosing
Machine list
Header or former make and model, die stations, and whether each machine is open or covered. Note any existing extraction.
Lubricant
The heading oil product name; the safety data sheet helps confirm the duty.
Working pattern
Strokes or parts per minute, hours per day, and how often covers open for setup or jam clearing.
Layout
Photos of the die areas and the space above and beside each machine, machine spacing, and any ducting routes.
Common questions about cold forging smoke extraction
Does the ESP series cover cold heading oil smoke?
Yes. The ESP series brochure's straight-oil machining application lists cold heading alongside hobbing, broaching, thread rolling and deep-hole drilling - processes where neat oil becomes airborne. Electrostatic cells capture the fine oil particles and drain the recovered oil.
Are the ESP collecting cells washable?
Yes. The ESP cells are washed and reused; the standard configuration uses no disposable filter media. An optional HEPA after-filter is a separate replaceable element.
Can one ESP serve more than one header?
It can when ducting and airflow are planned for the combined duty. Share the machine models, their positions and their working pattern and the arrangement can be checked.
Our headers are partly enclosed. Is extraction still needed?
An enclosure slows the spread but smoke still escapes at openings and when covers or doors open between setups. Extraction arranged at the enclosure or die area captures smoke before it reaches the shop air; send photos of the openings and guarding.
What should I send first for a cold forging application?
Your machine make and model (header or former type and die stations), the lubricant product name, strokes or parts per minute, photos of the die area and the space above it, and how many hours per day the machines run.
