Retort Furnace

Few heat-treating furnaces offer the range of benefits and advantages of retort ovens. Their versatility, precision, containment, and durability make them ideal for everything from retort laboratories to heavy industrial applications.

Foundry Furnace

One of the key components of any foundry operation is the foundry furnace, which is used to melt and shape metal materials into the desired form. There are five main types of foundry furnaces, each with its own unique characteristics and advantages.

Vacuum Tube Furnace

Vacuum tube furnaces are essential tools in industries that utilize high-temperature processes. These furnaces operate in a vacuum or controlled atmosphere, making them ideal for various applications such as crystal growth, heat treatment and thin film deposition.

What Is Fritted Glass?

Fritted glass has become a trendy option in modern architecture. It is also widely used in laboratories and industrial applications as a filter or scrubber. But what is fritted glass? How is it made? In our article, we’ll discuss how glass fritting is used today. Learn how to manufacture fritted glass and how its versatility has made it a favorite in modern building designs.

Guide to Glass-Melting Furnaces

Glass-melting furnaces are an integral part of the manufacturing process for a variety of industries and manufacturers. Most glass products today — from windows to bottles — make use of a glass-melting furnace at some point during the production process.

Guide to High-Temperature Furnace Heating Element Materials

Industrial heating elements are essential components in industrial furnaces. Capable of generating heat for high-temperature applications, furnace heating elements are vital components in a number of manufacturing processes. The choice of heating element material is crucial, as it must be able to withstand the required operating temperatures of your application along with the necessary electrical resistance properties.

Is Silicon Carbide A Ceramic

Silicon carbide has been used in manufacturing for over a century. Unique chemical properties make silicon carbide ideal for certain industrial applications. Since it is synthetically produced as silicon carbide powder, it brings up a very good question: Is silicon carbide a ceramic? And what is silicon carbide used for anyway?

How Does A Vacuum Furnace Work

Dozens of industries, laboratories and manufacturers rely on high-powered vacuum furnace systems to perform daily functions. From heat treatment to brazing and sanitation, vacuum furnaces perform a variety of duties that are crucial for a company to operate efficiently.

What Is Inert Gas Technology

Inert gas technology is essential to operating high-temperature atmosphere vacuum furnaces, which manufacture critical components for a wide range of industries. Because of the crucial nature of these parts, it’s necessary to carefully control the furnace temperature. This article will answer the question, “What is inert gas technology?” and review the roles that airflow and air pressure play in the process.

What Is A Foundry

The foundry process creates numerous products used in nearly every industry worldwide. But what is a foundry? Find out about industrial foundry work to understand this essential manufacturing process at Sentro Tech.

Glass Viscosity Measured

When working with glass, it’s essential to understand the relationship glass viscosity and temperature have with its final cooled form. Manufacturers use high-temperature glass furnaces and annealing ovens for various purposes, but without a proper understanding of how to measure viscosity during processes, glass workers will quickly find their finished products can become highly strained and often unusable.

Types of Ceramic Materials

What are the different types of ceramic materials? Learn more about the industrial ceramics process and how ceramic materials are used in modern manufacturing. Discover how ceramic raw materials are turned into finished products through sintering and heat treatment.

Annealed Glass

Untreated glass is brittle and can break easily and sometimes spontaneously. The process of annealing glass strengthens it, making the glass less likely to break. This article will answer the question, “What is annealed glass?” We’ll also look at the process of glass annealing and its benefits.

Freshly manufactured ceramic products

Ceramic manufacturing has come a long way since humanity made pottery using clay and other materials. While the technology has advanced, the ceramics manufacturing process has evolved with it to create modern materials used in everything from pottery, wall tiles and building materials to circuit boards and industrial ceramics products. In this article, we discuss the standard process of making ceramics using a number of different production techniques and equipment. From sintering at high temperatures to slip casting, let’s talk about the modern manufacturing process of ceramics.

A 3D Printer

The 3D metal printing process can open doors to a new world of manufacturing capabilities for both technology and business. Sintered 3D printing minimizes tooling costs, dramatically reduces the cost per part and provides geometric freedom only possible with additive manufacturing processes. Additionally, 3D metal printing has improved automation, as printers can produce parts automatically from CAD design files. As one of the most heavily invested and fastest-growing technologies in the manufacturing industry, leading manufacturers are already using the 3D metal printing process to rapidly prototype and print parts on-demand to great success.
