Stress Analysis of Ultem Component

Annealing or stress relieving of plastics can be an important step in plastic machining.

While not all components require annealing, there may be advantages for some materials and part configurations. Please contact our engineering department to discuss your particular application. Depending on material choice and target performance, we choose from multiple approaches to ensure long term success for the plastic component.

Connecticut Plastics has multiple programmable ovens for precise control of the stress relieving process. We can anneal components that are manufactured by us or by our customers. Injection molded blanks also may benefit from a stress relieving process.

Residual stress in machined or molded plastic parts is often a concern for engineers determining life span of a device. In conjunction with annealing, Connecticut Plastics offers stress testing and measurment. We can provide either optical or chemical testing to detect stress concentration after plastic machining. This approach takes into account both material and configuration effects.

Please consider the above as a brief summary of our technical plastic capabilites. Stress relieving and annealing, stress testing and measurement are topics that can be best covered by speaking with our engineering department. Please call for more information.
