Profile: Carville Ltd. specializes in manufacturing acrylic components, acrylic light guides and lenses, aerospace components and medical manifolds. We are an ISO 9001 certified company. Our products include micro fluidic devices, plastic manifolds, quality assurance phantoms, semi-conductor and valves manifolds. Our effective way to produce materials such as acrylic or PEEK is to use either a casting or extrusion process. Our cast acrylic or extruded PEEK materials can be highly stressed and have a surface skin which can pull and distort components during the manufacturing processes. On materials such as acrylic & PEEK, these initial heat treatment processes can result in material shrinkage of between 2% and 4%. We also offer services like heat treatment, precision machining, plastic machining, bonding of plastics, plastic polishing, plastic fabrication, design and development, CAD drawings and prototype services.
