Newthink Ceramic Evaporation Boat Production Workshop
Newthink’s advanced evaporation boat facility operates 12 twin-chamber vacuum hot-pressing furnaces. Utilizing precise isostatic pressing, we eliminate small internal cracks to deliver maximum ceramic density and structural integrity.
To ensure flawless metallization, each ceramic evaporation boat undergoes 100% pre-shipment electrical resistivity testing. Newthink delivers strict batch consistency, eliminating performance variations during high-speed coating.
Protective Packaging for Ceramic Evaporation Boat Delivery
Ceramic products are fragile. They need careful packaging to endure transport and moisture. Our ceramic evaporation boats are vacuum-sealed, and every 10 units are placed into a moisture-proof bag. Then they will be packed into high-density master cartons, which can contain 100 units.
Reinforced with shock-absorbing foam padding, our multi-layer packaging can effectively reduce transport breakage risks. We ensure every shipment arrives intact and ready for immediate furnace loading.
Ceramic Evaporation Boat for High-Speed Film Metallization
In packaging production, achieving high-barrier PET and BOPP films requires fast, uniform aluminum deposition.
Ceramic evaporation boats ensure smooth aluminum spreading without splashing during continuous operation. They prevent pinhole defects and improve barrier performance against moisture and oxygen. Using them will optimize heating efficiency, allowing high-speed metallizers to maintain consistent quality across large-volume film rolls.
Ceramic Evaporation Boat in Actual Industrial Application
Industrial manufacturers replacing standard parts with high-density ceramic evaporation boat experience significant operational improvements.
The boat can operate at stable working temperatures up to 1,550℃. Moreover, it exhibits superior resistance to thermal shock and molten aluminum corrosion.
100% pre-tested resistivity guarantees tight batch-to-batch consistency across multi-boat furnace setups, reducing machine recalibration time. This also minimizes overall downtime during continuous metallization runs.

A ceramic evaporation boat is made from a two-component composite: Boron Nitride and Titanium Diboride. This advanced formulation ensures high purity, free of contamination, and superior corrosion resistance.
Titanium diboride is added to the ceramic evaporation boat as a conductive phase. This allows electrical current to flow and generate fast, uniform resistance heating for efficient metal vaporization and tailored electrical resistivity.
Acting as a self-heating electrical resistor, the ceramic evaporation boat heats up when powered in a vacuum. It rapidly melts aluminum wire into a uniform liquid pool, vaporizing it into an ultra-thin, flawless metallic layer onto moving film substrates.
Lifespan depends on operating temperature. Operating our ceramic evaporation boat at the optimal 1,500-1,550℃ delivers maximum durability.
The recommended operating temperature is 1,500-1550℃. Staying below 1,600℃ maximizes vaporization efficiency while preventing premature thermal degradation, whereas running at 1,700℃ cuts product life by 50%.
A higher-resistivity ceramic evaporation boat heats with greater thermal efficiency, reducing internal thermal shock during ramp-up. This controlled energy distribution slows material wear and corrosion from molten aluminum, which significantly extends operational life during long production runs.
Depends on your film speed and aluminum feed rate. Various patterns promote smooth aluminum spreading and prevent splashing. We customize cavity grooves for your ceramic evaporation boat to optimize liquid pool stability and guarantee uniform film thickness.
Cracking occurs due to thermal stress, poor density, or moisture absorption. Our ceramic evaporation boat utilizes cold and hot isostatic pressing to eliminate micro-defects, while vacuum-sealed packaging prevents moisture pickup, ensuring exceptional thermal shock resistance during rapid heating cycles.
Choose a ceramic evaporation boat with tailored electrical resistivity, use high-purity aluminum wire (99.99%), and select custom cavity patterns.
Keep the ceramic evaporation boat in its original vacuum-sealed packaging until installation. If unsealed, store boats in a controlled constant-temperature and constant-humidity environment, or use them immediately.
The ceramic evaporation boat is vastly superior. Graphite boats suffer from severe molten aluminum erosion, dust contamination, and short lifespans. Our advanced BN-TiB ceramic boat provides outstanding corrosion resistance, longer service life, and ultra-clean, defect-free coatings.
Boron nitride offers superior corrosion resistance against aggressive molten aluminum and zero chemical reactivity. Besides, unlike graphite, boron nitride evaporation boats create no carbon dust or particulate pollution. It guarantees perfect film purity and significantly longer production life.
