How high borosilicate glassware is processed?

Glass is one of those products that have different functions, which makes it unique. There are different types of glass storage containers, which are made from different types of glass. Besides being used as a utility, glass is also used for decorative purposes in different societies. We are a high borosilicate glassware manufacturer and have been in the business for a while.

In the glass manufacturing industry, there are two main methods used in the production of glass bottles and containers:

1.      Pressing-blowing

2.      Blow-blown

Pressing-blowing

Manufacturers use this type of method to make different forms of containers. If you are searching for a glass jar for storage, chances are it will be made using the pressing-blowing methods. One of the advantages associated with this method is the fact that it gives better control of the distribution and shape of the glass.

Glass made with this method has an inner cavity that flows in the downward direction. This is made using a long punch and it is quite different from the conventional method of making glass.

Blow-blown

This is the common method you will witness in the manufacturer of bottles and glass containers for storage. The main difference with the pressing-blowing method is that the punch used is smaller and as such, the inner cavity is smaller. Once the molten glass forms the cavity, it is expanded using compressed air.

If there is a specific shape that we are targeting to achieve, this expansion will force the glass to conform to the desired shape. Ultimately, we will have the shape and design of the container that we intended to make.

Uniqueness Traits of Borosilicate Glass

Borosilicate glass is a superior type of glass and is considered to be one of the best options for glass containers for storage. The fact that it contains boron trioxide gives it an extremely low coefficient to support thermal expansion.  As such, even when exposed to extreme temperatures, it would not crack as traditional glass. Durability is one of the key reasons why wineries, laboratories, and restaurants prefer borosilicate glass. With this in mind, it is worth noting that not all glass is made in the same manner

With about 15% composition of borosilicate glass being boron trioxide, this glass has the ability to resist thermal shock. The rate at which it expands when exposed to heat is very low, which is the most unique property of borosilicate glass. Unlike regular glass, you can move borosilicate glass food containers from your freezer to the oven and they will not crack. As such, most high-end glassware is made from this glass as it has so many benefits to offer.

Customers desire different things and we are equipped with the right technology to manufacture the specific products. Over the years, we have made an extensive range of borosilicate items including microwave glass, washing machine glass doors, oven glass trays, and so many other products.

Before getting to work, we will evaluate each product and create a drawing for it. A feasibility review is performed and our experts will discuss with the customer to agree on various aspects. Once we have agreed on various logistics, we will begin the development process and let you know how long it will take. All products are tested after manufacturing to ascertain that they are of sound quality.

We have different teams of experts who work on the production of glass storage containers. Our specialists will confirm the specific products or drawings that have been availed by the customers. We will run a mold design of the product you need and manufacture it according to your specification.  From the initial production, we will continue making improvements and finally, we will have the final sample delivered to you.

Upon confirmation of the final product, we will commence the mass production of the glass food containers. The heat-resistance glass is a preferred choice for most people due to its unique capabilities. You will certainly love borosilicate glass products due to their unique nature and durability.

Glass Storage Container Production Flow Process

You will agree that the quality of any product is as good as the raw materials. As such, we are keen on the quality of the raw materials used in the production of glass storage containers. We import all materials from Turkey and the United States. Borax, silica sand, and other materials are mixed in the right portions. There are technical requirements that we are keen to ensure we meet in terms of the mixing ratios.

Once all the ingredients and raw materials are in place, we will melt them together at 1,600 °C. In order to ensure that the clarification and melting process is stable, the automatic feeding system and liquid surface are used together. We have a wide range of machines, which will work together with the molten glass feeding system to develop a couple of products. We have a glass jar for storage, round glass, glass bowls, food storage containers and so much more. There are over 400 molds in our catalogue.

To eliminate the rough parts and ensure that the glass is smooth, we will polish it using fire. The products come in different shapes and sizes and we will anneal all of them. The purpose of the annealing process is to ensure that the glass has its specific physical characteristics. This is also a process that eliminates the internal stress of the glass effectively.

Finally, the products which include glass food containers, glass storage containers, bowls, jars, and other items are inspected. This is to ensure that the customers’ specifications are met and the quality of standard is achieved. The glassware is then packed and shipped to the recipients in safe and approved packages.

Different Types of Glass Storage Containers

We are happy to be the high borosilicate glassware manufacturer and as you may have noticed, we have so many products to offer. Similarly, there are different types of glass containers for storage. Some of the common ones include:

Untreated Glass

Untreated glass is quite common as it is the cheapest option to manufacture. This type of glass is made from untreated soda-lime and you will see it around you. There are many bottles, jars, cups, and storage containers made from untreated glass. The fact that it is a cheap option does not mean that it is useless; in fact, it is perfect for storing items at room temperature. However, if you want to heat or freeze the glass, this may not be the best choice for you.

Tempered Glass

Tempered glass is also made from soda-lime, with the difference being that it is heated. This process of heating is known as tampering and this gives the glass the ability to withstand varying temperatures. Such glass will hardly shatter even when it falls, and when it breaks it will disintegrate into very tiny pieces which are harmless. Your glass jar for storage will probably be made of tempered glass and it is also commonly used on shower doors, car windows, microwave doors, and food containers.

Borosilicate Glass 

Borosilicate glass has boric oxide as the main ingredient. As such it has a higher capacity to withstand extreme temperatures and resist shock. This is the most expensive type of glass to produce due to its unique characteristics.

These are the main types of glass that you will find on the market. When looking for glass food containers, safety is one of the key considerations to bear in mind. Tempered and borosilicate glass are ideal for different uses and are better than untreated glass.
