A client in the office furnishing industry reached out to us with a unique requirement: they needed a top cap for an office furniture panel system that met specific dimensions and finish criteria. Achieving the desired smooth surface at the points where the legs intercept with the top of the panel was a particular concern.

The client chose to work with Paul Murphy Plastics due to our specialized focus on plastic profile extrusions, a level of expertise that multi-focused competitors simply can’t match.

Utilizing our extruder and automated saw, we produced a top cap out of integrally colored rigid polyvinyl chloride. The part measured 3.75″ wide by 0.50″ tall, with a pinch distance of 0.010″. To meet the customer’s requirements for durability, we applied a UV protective finish as specified.

In keeping with our standard procedures, we conducted multiple tests and inspections on the extrusions. These checks verified the smoothness of the surface, confirmed the profile dimensions, checked the straightness over the length of the piece, and reviewed the color match.

By meeting the exact specifications laid out by the customer, we were able to deliver a top cap that perfectly aligned with their vision. This successful implementation not only fulfilled their technical requirements but also served as a testament to our capabilities in specialized extrusion projects. The timely and cost-effective completion of this project further strengthened our reputation as a reliable partner in the office furnishing industry, ready to tackle even the most intricate and demanding extrusion needs.

Let Paul Murphy Plastics extrude the exact piece to meet your needs. Contact us for more information.
