Contiblu®¨ is our oxidation belt kiln for the continuous steam curing of PM shaped parts.
The background: under oxidizing water vapor atmosphere iron oxidizes to Fe3O4 and forms a firm, wear and rust-protecting magnetite layer on the parts. The effect of the steam curing is therefore not only the corrosion and catch ice protection, but also the hardness increase of PM parts. This hardness increase adjusts itself, if first empty pores zuoxidieren by magnetite formation ""and the total stand of the PM of part thereby larger firmness attained.

The conglobulating annealing furnace is the continuous furnace used to anneal parts of car, machine and electronics devices in order to improve the treatment and quality.
It is especially praised for economically dramatic energy reduction by transferring heat and flue gas generated from cooling pad and homogeneous pad to preheating pad to be used to warm up materials. It is classified to the roller hearth and the tray pusher depending on operational methods.

Ensure reliable, repeatable sintering and infiltration results of your metal parts and tooling inserts made from LaserForm material with the specially designed LaserForm oven - from 3D Systems
Sinter and infiltrate parts and inserts made from LaserForm material
Metal parts and tooling inserts produced on an SLS® system like the Vanguard system (pictured) must be sintered and infiltrated using the LaserForm oven from 3D Systems.
The LaserForm oven is the only oven made specifically for sintering and infiltrating parts, prototypes, or tools made with LaserForm material. Its unique combination of features and automation deliver the reliable, repeatable results you need to improve designs, meet deadlines, and shorten production cycles.
Count on simple, automated, operation. The LaserForm oven is pre-programmed: just push a button and it automatically adjusts the temperature for each step of the process. Sensors automatically make additional adjustments in each of the three temperature zones, if needed. Nitrogen flow stops when the oven reaches a preset temperature, and the oven powers itself down at the end of the process. A built-in motorized crane makes loading and unloading parts a one-person job.

Car Bottom Furnaces can be provided for annealing, normalizing and stress relieving bars, tubes, forgings, large weldments and castings and can be gas fired or electrically heated with either guillotine or bulk head doors. Sand or pneumatically operated mechanical car seals are available.
Tip-Up Furnaces are used where better atmosphere control and temperature uniformity are necessary. Alternate load/unload methods are available.
A Wellman direct gas fired Tip-Up Furnace with a car bottom hearth is shown below for normalizing alloy steel castings. This system combines the Tip-Up advantages of a tight seal and better temperature uniformity with the convenience of loading and unloading on a moveable car with a refractory hearth.
