Evaporation Boats
Our primary competence: a highly flexible production process that yields boats to moot a customer’s required specifications!
WE USE THE KNOWLEDGE GAINED BY WORKING CLOSELY WITH METALLIZERS IN ALL MARKET SECTORS TO PRODUCE OPTIMAL EVAPORATOR BOATS FOR EACH APPLICATION.
THE MOST ADVANCED PRODUCTION TECHNOLOGY
Using the most advanced production equipment and technology to improve the long-term stability of the product, the products have world-class performance and quality, to meet the production of metalized film, paper, textiles, and other materials, widely used in the vacuum evaporation packaging materials, capacitor metal vacuum coating, paper, aluminum plating, bronzing coating, anti-counterfeit labels such as aluminum plating industry.
- Using the high purity raw materials; ensure the material has the best chemical property.
- Adopt international advanced vacuum hot pressing sintering; ensure the evaporation boat materials have stable physical properties.
- Pressed with two-way, ensure the ceramics have consistent volume density properties.
- Production equipment digital control to ensure stable and reliable product quality.
- A unique formulation process and optimum composition, the evaporation boats enhance high thermal shock resistance and breaking strength. Increased the molten aluminum spreading, evaporation efficiency, resist molten aluminum corrosion and extend the working time.
BOATS FOR THE METALLISING INDUSTRY
Unique thermal shock resistance and chemical inertness against liquid Aluminium are basic requirements for boats to be used in the production of metallised films, papers, textiles and other components such as Cathode Ray Tubes (CRT) and decorative parts.

PRODUCTS OPERATING ADVICE
To ensure optimum boat performance and to maximize boat life, the following procedures should be followed:
- Check alignment and smooth surface of your contacts.
- Use graphite tape for uniform electrical and thermal contact.
- Adjust wire feed to the very central position on boat-surface.
- Follow heat-up cycle to ensure reannealing of boats during first heat up (approx. 12-14 minutes).
- Start wire at 75% of normal feed rate and reduce power to achieve maximum wetting over length of cavity.
- Start metallizing and increase wire feed rate over the first 15 minutes of production.
- Upon completion of the coating:© Stop the wireo Stop power 20-30 seconds later.
- Wait approx. 2 minutes to release vacuum to ensure boats have cooled to below redheat.
- Clean boats with a wire brush after every cycle.
