Aluminum Process

One of the best ways to strengthen an aluminum alloy is through a solution treat and aging process at Modern Industries. Our solution treating is typically performed between 890-1010° F which is followed by a six second quick quench. The process typically ends in an aging furnace where the material finalizes its hardening process.

Vacuum Process

At Modern Industries, we have multiple vacuum furnaces and we use the most efficient and technical equipment available to guarantee a fantastic experience and end product. Our Vacuum Processing helps reduce size changes and eliminate many of the problems often associated with other methods of processing.

Atmosphere

Modern Industries has the equipment and ability to process parts from multiple steels and alloys within a wide range of sizes. Batch furnaces are equipped with oil or water quench, protective atmospheres, state of the art computerized controls, and constant monitoring/data collection of all processing parameters in our furnaces.

Gas Carburizing

Carburizing is a heat treating process in which iron or steel absorbs carbon liberated when the metal is heated in a carbon enriched atmosphere. The process leads to a hardening of the metal which allows the product to be used in a wider variety of outputs due to the increased hardness.

Induction Hardening

Modern’s Induction Hardening machines can be configured as a single or dual spindle, vertical scanning system for hardening or tempering a wide variety of parts. It’s equipped with quick disconnects to allow for faster tear down and set-up times. The variable frequency capability makes this machine ideal for meeting the stringent requirements of wrought alloys or even the toughest powdered metal profiles and case depth requirements.

Carbo-nitriding

Carbo-nitriding is a metallurgical surface modification technique that’s used to increase surface hardness of a metal as well as reduce wear. The carbo-nitriding process involves the diffusion of both carbon and nitrogen into a base steel which can be carried out in a furnace gas.

Ferritic Nitrocarburizing

Ferritic Nitrocarburizing encompasses a range of case hardening processes that diffuse nitrogen and carbon into ferrous metals at sub-critical temperatures. The processing temperature ranges depending on the job. FNC has a high resistance to wear and it’s more resistant to corrosion than other types of processing.

Continuous Belt Processing

Continuous furnace heat treatment can be defined as any industrial furnace that utilizes a cast-link or mesh-link belt to move fabricated items through a primary heating chamber for swift thermal hardening. Continuous belt furnaces feature a tunnel structure that provides rapid thermal adjustments as well as evenly distributed heat to deliver a uniform treatment to the intended products. This manner of heat treatment allows for flexible capabilities pertaining to part-loading, reduced changeover time, stable temperature regulation, and the ability to combine multiple processes or part types in a single run.

Modern Industries performs neutral hardening, case hardening, and carbo-nitriding operations with polymer/water or oil quench capabilities in our continuous furnaces.

(1) 48″ W x 4″ H Cast-Link Belt Furnace – 1,500 lbs. per hour
(1) 36″ W x 4″ H Mesh-Link Belt Furnace – 1,500 lbs. per hour
(1) 24″W x 4″H Mesh-Link Belt Furnace – 750 lbs. per hour

Continuous furnace heat treatment offers unique benefits over batch furnace applications and is capable of achieving multiple types of hardening depending on the required end use or specifications. Modern Industries continuous belt processing heat treatment provides three different hardening techniques. Each specific operation delivers unique benefits tailored specifically to benefit the final applications. These are neutral hardening, case hardening, and carbo-nitriding.

Neutral Hardening: a continuous heat treatment hardening process that alters the required surface and core hardness specs of steel to provide incredible strength throughout the complete composition. Neutral hardening can be used for products that will experience a high load such as fasteners, tools, dies, and shafts.
Case Hardening: a heat treatment process used to harden the surface of a metal while maintaining a ductile inner core combining the properties of both hard and soft metal into a singular part. Case hardening can be used on parts like bolts and gears, where the teeth and grooves necessitate a hardened surface to repair wear resistance.
Carbo-Nitriding: a case hardening process achieved by supplementing nitrogen via NH3 gas to create a hardened surface layer that improves surface hardness and increases wear resistance. Carbo-nitriding is a suitable solution for the mass production of smaller components like pistons, rollers, and bearings.
