Many parts today are cast or injection molded. It’s an efficient way to mass-produce parts, but there are disadvantages. For example, when you pour or inject molten material into molds, it forms a flashing. In some cases, burrs are formed, and they need to be removed in the most efficient and cost-effective manner. This is why thermal deburring in Grand Rapids is commonly used and here are some of the many benefits it provides.
What is it?
Thermal deburring is often referred to as TEM (thermal energy machining). Burrs can form on parts from the process of machining. For example, when you drill holes or mill metals, it creates a built-up edge on the surface. It’s possible to manually remove all the burrs by using a machining process. However, this is time-consuming, and some areas are nearly impossible to reach with standard tools or machinery. TEM is an effective way to finish products in Grand Rapids.
TEM works by applying heat to metals, and this literally burns away burrs and flashing. The parts are placed in an oven that contains a deburring chamber. The process creates a sudden burst of very high heat (around six thousand degrees Fahrenheit).
This process does not melt the metal part and here is why. The burr absorbs most of the heat because it’s less dense than the rest of the part. This causes heat to quickly reach its ignition point in the burr or flashing, and it simply burns off, leaving the rest of the part untouched. The body of the part absorbs remaining heat, and this quenches the flame.
Benefits
Thermal deburring is more efficient than most methods in Grand Rapids and can be used on:
- Stainless steel
- Zinc
- Aluminum
- Cast iron
- Bronze
- Brass
- Steel
If you want cost-effective finishing, TEM is an excellent choice.
