Evaporation Boats Manufacturers/Suppliers in Surat


What Are Evaporation Boats?

Evaporation boats are durable, heat‑resistant ceramic components used in vacuum deposition systems for metals like aluminum, copper, and silver. Composed of materials such as titanium diboride and boron nitride, these boats withstand high temperatures and corrosive environments, making them essential for applications like thin‑film metallization.


Key Features & Benefits

Manufacturers, notably Supervac Industries in India, highlight several advantages of their evaporation boats:

  • High thermal stability and thermal shock resistance due to composite ceramic materials.

  • Exceptional density and strength (≈98% theoretical density, bend strength ~110 MPa).

  • Optimized resistivity and wettability, ensuring efficient heating and smooth metal deposition.

  • Cost savings from longer service life (up to 37% longer), reduced energy use, and higher yield .


Typical Applications

These evaporation boats are widely used in industries such as:

  • Packaging and capacitor film manufacturing — where uniform metal coating is critical.

  • Roll‑to‑roll metallization processes, which demand continuous, high‑quality deposition.


Surat & Gujarat as a Manufacturing Hub

While Supervac is based in Mumbai/New Delhi, Surat and nearby Gujarat cities host several evaporation-system and vacuum-component suppliers. Trade directories list manufacturers in Ahmedabad, Vadodara, and Surat providing evaporators and related equipment.


How to Choose the Right Evaporation Boat

Consider the following factors:

  1. Material composition (e.g. titanium diboride + boron nitride ratio)

  2. Electrical resistivity – optimal range ensures controlled heating 

  3. Wettability — for smooth, defect‑free metal layering 

  4. Corrosion resistance — to prolong service life despite high-temperature metal contact 

  5. Quality, lead time, and cost — balance upfront investment versus long-term performance


Final Thoughts

Surat and the broader Gujarat region benefit from a robust ecosystem of manufacturers and suppliers in vacuum-related technologies. Evaporation boats—particularly those designed for high‑performance and cost efficiency—play a crucial role in industries such as packaging, electronics, and metal processing. When selecting a supplier, focus on material quality, performance metrics (density, resistivity, wettability), and logistical factors like lead time and cost.

Evaporation Boat for Metallizing: A Comprehensive Buyer's Guide

Image
In the world of vacuum metallizing, evaporation boats play a crucial role. These essential components ensure the efficient deposition of metal coatings onto various substrates, making them indispensable in industries such as packaging, electronics, and automotive. For buyers seeking the best evaporation boats for their metallizing needs, understanding the key factors that influence performance and quality is paramount. This guide from Okosuceratech.com will walk you through everything you need to know to make an informed purchase. What is an Evaporation Boat? An evaporation boat is a specialized device used in the vacuum metallizing process to vaporize metals like aluminum. The vaporized metal then condenses onto the surface of a substrate, creating a thin, uniform metallic layer. This process is widely used in creating reflective surfaces, conductive coatings, and decorative finishes. Evaporation boats are typically made from ceramic materials like boron nitride, titanium diboride, or...
