The Challenges of Powdered Metal Production

PM manufacturers face technical and operational barriers that affect cost, quality, and consistency:

High Ejection Force

Conventional lubricants create high ejection pressures that shorten die life and increase costs.

Density Variability

Inconsistent green strength and density cause part defects in powdered metal production.

Corrosion Risks

Without specialized lubricants, parts corrode during sizing, finishing, or storage.

Emission Concerns

Zinc-based lubricants generate harmful furnace emissions that fail eco-compliance.

Trial Costs

Trial-and-error blends waste time, reduce efficiency, and increase costly downtime.

Cost & Downtime

Poor anti-tack performance leads to costly rework, downtime, and material losses in production.

Powdered Metal Lubricant FAQs

What are powdered metal lubricants?

Specialty additives blended directly into the metal powder mix to improve flow, reduce ejection force, strengthen green parts, and support clean, high-integrity sintering.

How are Blachford’s PM lubricants different?

The Caplube® portfolio includes non-zinc, low-ash grades (e.g., Caplube® L) engineered for high density and cleaner burn-off, plus Markee™ secondary-operation lubricants for sizing/machining and long-term corrosion protection.

Do I need special equipment to use these lubricants?

No. They blend directly into the metal powder using standard mixing equipment—no hardware changes required.

Where in the process are they used?

In both pressing and sizing operations to ensure flow, green strength, ejection control, and sintered integrity.

What dosage levels are required?

Similar to conventional lubricants, making adoption straightforward and changeover simple.

Can these lubricants help cut tool and die costs?

Yes. By reducing ejection pressures (often 10–30%), they extend die life, lower maintenance, and increase uptime.

How does Blachford ensure consistency?

Every batch is application-tested in iron mixes to validate flow, density, green strength, ejection, and sintered properties before shipment.

What in-house testing capabilities do you have?

A full PM lab with a sintering furnace, laser-diffraction particle size analysis, and standard PM test rigs that mirror real production conditions.

Can you customize a formulation for our parts?

Absolutely. Blends are tailored to target density, alloy system, press tonnage, and geometry, with validation testing for performance assurance.
