MIM Process Overview – MIM Furnace Criteria

Continuous Sintering Furnace

In MIM design there are many variations of the initial forming process where MIM manufacturers add their particular process differentiators.  Whether your processes involves metals or ceramics, the key to reproducible production of precise metal parts requires a carefully planned and controlled sintering/debinding operation. Molding plastic parts is similar to molding metal parts in many ways such as designing draft Read More

What is a Muffle Furnace?

While the term “Muffle Furnace” or “Retort Furnace” is still in use today, it doesn’t really mean the same thing as it did in the early 20th century when wood and coal were the primary ways to heat a furnace. A Muffle Furnace’s primary attribute is that it has separate combustion and heating chambers. The “Retort” is a gas sealed chamber Read More

The Use of Furnaces in 3D Printing

While manufacturers scramble to realize the full promise of 3D metal printing with new methods, better throughput and more accuracy, a survey of 3d Printing technology in 2017 shows that Powder Bed Fusion, or Direct Energy Deposition methods still dominate most equipment. Both these methods require a sintering phase where the printed part is purged of catalysts, and non-uniformities introduced Read More

Convenience of 3D Printing with High Volume Production

Annealing Furnace, Strand Anealer
3D Printing for High Volume Production Additive manufacturing or “3D printing” has come a long way since originally introduced in the 1980’s as a method to conveniently create prototype parts out of plastic.. Additive manufacturing can now be used with various materials including metal and ceramics, giving injection molders an alternative process for building parts. With new, highly sophisticated 3d Read More

Primer on Strand Annealing Furnaces

Annealing Furnace, Strand Anealer
In the late 1940’s continuous strand or strip annealing lines came into use in brass producing mills. The modern strand annealing tube furnace has for decades played the dominant role in annealing of wires, ropes and tubes made of stainless steel and nickel alloys. But what is the annealing process and how do CM furnaces specifically facilitate the strand annealing Read More

What is Ceramic/Glass Annealing?

Continuous Strand annealing furnace

Annealing occurs by the diffusion of atoms within a solid material, so that the material progresses towards its equilibrium state. Heat increases the rate of diffusion by providing the energy needed to break bonds. The movement of atoms has the effect of redistributing and eradicating the dislocations in metals and (to a lesser extent) in ceramics. This alteration to existing Read More
