Glass Preforms VS Sealing Glass Powder
Your choice between granulated powder and glass preforms depends on your specific needs,
the capabilities of your manufacturing process, cost considerations, and convenience.
Glass Preforms
If you prefer convenience and simplicity, choosing glass preforms can streamline your manufacturing process. Ideal for when you don't have pressing capabilities in-house or when you want to bypass the complexities of pressing, preforms provide a ready-to-use solution that can significantly enhance efficiency and consistency.
Sealing Glass Powder
If you have your own pressing process and are looking for maximum control or aiming to reduce costs, granulated powder might be the right choice for you. This allows you to utilize your existing capabilities to create preforms exactly as you need them, offering unparalleled flexibility in design and production.
Glass Preform Manufacturing:
Process and Key Considerations
- Raw Material Selection
- Batch Preparation
- Forming the Preforms
- Precision Shaping
- Quality Control
- Packaging and Shipping
Raw Material Selection
Quality Glass Powder
The process begins with the selection of high-quality oxides. The composition of the glass is chosen based on the intended application and desired properties, such as melting point, thermal expansion, and chemical resistance.
Additives
Sometimes, additional materials are added to modify the properties of the glass, like improving flow characteristics or changing the thermal expansion coefficient.
