Why You Need to Remove Bubbles

Structural defects — Bubbles create voids, weakening adhesion and causing delamination.

Surface flaws — Air pockets lead to pinholes and craters on coated or cast surfaces.

Performance loss — In optical and conductive materials, bubbles degrade clarity and conductivity.

Process failure — Bubbles cause dispensing inconsistencies, component defects, and higher scrap rates.

Eliminating bubbles is central to achieving reliable, high‑quality production.

Why SIE‑VH350

0–2000 RPM adjustable High centrifugal force pushes bubbles out fast

‑99 kPa deep vacuum Extracts even micro‑bubbles thoroughly

Non‑contact planetary design Zero contamination – material properties unchanged

Low noise ≈ 50 dB Fits labs and quiet production rooms

Flexible syringe config 1–96 pieces; 30–300 cc standard, up to 3500 cc

Digital recipe storage 100 pre‑set programs for repeatable results

Optional MES / cooling / heating Seamless in‑line integration & process traceability

Working principle

Principle of centrifugal defoamer: By using the principle of gravity downward to release bubbles, it can efficiently remove tiny bubbles from materials and improve product quality.
