Why Must Microbubbles in Materials Be Eliminated?
Residual micro‑bubbles degrade end‑product quality directly
Resin Craft IndustryBubbles in epoxy resin crafts create surface pores and internal voids, especially noticeable on transparent parts and trigger customer rejection. Vacuum defoaming expands and releases bubbles under negative pressure. Heating cuts resin viscosity to speed defoaming. The 72L dual‑layer chamber processes multiple crafts simultaneously for one‑batch small‑batch processing without separation. | Plastic Toy IndustryBubbles in toy potting compounds cause poor encapsulation and weak sealing. Bubbled coatings feature low adhesion and easy peeling with unstable yield in small‑batch runs. Non‑contact vacuum treatment preserves material composition. 72L chamber with dual mesh plates pre‑processes potting and coating materials for higher efficiency. | AB Adhesive IndustryBubbles generated after two‑component AB‑glue mixing bring voids on bonding surfaces and weaken structural strength. Stable repeatable defoaming is required for small‑batch consistency. Pressure‑holding leakage merely 1kPa/h maintains steady negative pressure. 72L chamber with dual mesh plates handles multiple bonded parts for consistent defoaming results. |
✨ Dilemmas of conventional solutions: Large‑size equipment wastes energy and preheating time for small‑batch production, while small‑size devices require multi‑batch queuing, making capacity‑efficiency balance hard to achieve. External vacuum pumps occupy large footprint with complex pipelines and leak‑prone joints. Ordinary units suffer poor pressure retention, frequent pump cycling generates loud noise and shortens pump service life.
Why Choose SIE‑ZK400
Solve efficiency‑stability pain points for small‑batch production
Integrated Built‑in Vacuum PumpBuilt‑in vacuum pump requires no external accessories for plug‑and‑play operation to save production‑line space. All‑in‑one structure prevents leakage at pipeline joints for more reliable vacuum system. Reaches ‑100kPa within 3‑5 minutes for fast defoaming startup. | Excellent Pressure‑Holding PerformancePressure‑holding leakage rate approx.1.0KPa/hour sustains long‑term negative pressure inside chamber. Vacuum pump auto‑stops at target vacuum and restarts below threshold to maintain constant pressure. Low pump‑cycling frequency reduces noise and extends pump service life. | 72L Dual‑Layer Operation400×400×450 mm chamber equipped with 2 mesh plates processes multiple items simultaneously for single‑run small‑batch defoaming. Seamless transition from lab samples to small‑volume production. One unit covers prototype‑to‑mass‑transition demands. |
✨ If you run small‑batch production requiring stable pressure retention, compact footprint or simultaneous multi‑item processing, ZK400’s built‑in pump and 72L dual‑layer chamber balance capacity and efficiency.
Working Principle
Bubbles expand and burst under negative pressure for gas escape to improve material compactness.
Step 1: Vacuum pumping to build negative pressure: The built-in vacuum pump reaches -100kPa within 3-5 minutes. The negative pressure environment expands bubbles inside materials. Step 2: Heating-assisted defoaming: Thermal radiation heating adjustable from room temperature to 300°C reduces material viscosity and accelerates bubble rupture and escape. Step 3: Non-contact purity preservation: Materials stay static inside the vacuum chamber with no contact from stirring paddles, keeping the chemical properties of materials unchanged. Simple three steps: Vacuum Pumping → Heating Assistance → Non-contact Purity Preservation to improve material compactness. | ![]() |

What is the function of a defoaming machine?
A defoaming machine is a device used to remove bubbles from liquids. Its function is to assist in the liquid mixing, reaction, coating, printing, infusion and other process steps in the production process, avoiding the generation of bubbles and their impact on the final product. In many industrial and laboratory environments, removing bubbles is essential as they may have a negative impact on product quality, such as affecting surface tension and stability. Defoaming machines typically use various techniques such as vibration, ultrasound, centrifugation, etc. to achieve effective bubble removal. It has a wide range of applications, including but not limited to semiconductors, solar energy, optics, biotechnology, materials science, etc.
