PVC (polyvinyl chloride) can be suitable for plastic vacuum casting. Here are a few key points about using PVC for vacuum casting:
PVC is a commonly used material for vacuum casting due to its good dimensional stability, strength, and ability to capture fine detail.
PVC has a relatively low melting point compared to some other thermoplastics, making it easy to melt and cast using vacuum casting techniques.
The low viscosity of molten PVC allows it to flow well into the mold cavity under vacuum, helping to fill intricate details.
PVC parts made via vacuum casting can have good surface finish and dimensional accuracy, though the properties may not be as consistent as injection molded PVC parts.
Appropriate mold release agents and mold design are important to ensure successful demolding of PVC vacuum cast parts.
The brittleness of PVC should be considered, as vacuum cast PVC parts may be more prone to cracking or breaking compared to more flexible plastics.
Overall, PVC is a common and well-suited material for plastic vacuum casting when the part design and casting process are optimized. The specific suitability depends on the part requirements and the details of the vacuum casting setup.
