When machining Delrin parts, it’s important to note that Delrin is a thermoplastic. A thermoplastic is essentially a plastic polymer that becomes pliable at a certain temperature, and then solidifies upon cooling. Common thermoplastics include acrylic and polyester, though Delrin plastic is also a thermoplastic.
The process of machining Delrin plastic is different from machining a thermoset. A thermoset is different from a thermoplastic because it remains “set” once formed, while thermoplastics melt in the heat. For that reason, it helps to know the Delrin material temperature range when working with this material.
So what does it take to machine Delrin plastic? As mentioned, Delrin plastic material is a popular choice in molding and plastics industries because it’s strong, stable, and easy to work with. For applications that need tight or specific tolerances, these Delrin material properties are extremely important. In order to machine Delrin parts, keep in mind that Delrin is sensitive to heat at or about 250F. If you aren’t aware of the Delrin temperature range, you risk deforming the plastic before it reaches its final application.
Here at Jaco, our experts understand the intricacies of machining Delrin parts and can expertely work with Delrin plastic material to meet your requirements.
In order to cool Delrin bushings, consider air-based coolants. This will achieve close tolerances as well as provide a smooth finish. With the right coolant, you can extend the life of Delrin plastic parts.
Another key aspect of machining Delrin plastic material is to avoid any contamination. There are certain demanding industries, like medicine and aerospace, that need Delrin parts that won’t fail. Because of this, the highest level of sanitation needs to be established and maintained by Delrin material suppliers. Jaco Products understands the level of precision and accuracy required to safely process Delrin plastic material, and deliver products to our customers that meet exact specifications. Where other plastic processing companies may shy away from machining Delrin parts, we are eager to take on even the most complex projects.
