Our client presented us with a unique and complex task: they needed a specialized edge molding to trim and finish the perimeter of a marker board. The intricacies lay not just in the custom shape of the edging but also in the exceptionally tight tolerances specified. The specifications demanded a degree of accuracy that would challenge the skill set of any manufacturer. It was a challenge that demanded our utmost attention to detail and expertise in the art of plastic extrusion.

The client opted for Paul Murphy Plastics, drawn not only by our specialization in precision plastic profile extrusions but also by the trust we’ve earned from our many valued customers. Our reputation for delivering top-quality products, coupled with a consistent track record of meeting challenging specifications, made us the natural choice for their demanding project.

To tackle this challenging project, we engaged our state-of-the-art equipment tailored for high-precision plastic extrusion tasks. The first step was to carefully set up the extrusion parameters to achieve the specified dimensions of 0.72″ wide x 0.67″ high. After the extrusion process, we executed precise cuts to ensure the outer edge-to-center tolerance was held to an impressive ±0.007″. Throughout this, we paid special attention to the client’s requirement for a matte finish. The end result was a meticulously crafted, integrally colored polypropylene edge molding that fully met the client’s demanding specifications.

The client was extremely pleased with the final product, confirming that we had met each and every one of their challenging specifications. This successful project not only solidified our standing as a trusted partner for intricate plastic extrusion tasks but also showcased our commitment to quality and precision in all that we do.
