Contract Manufacturing Considerations
Coextrusion is a complex process and, as new materials continue to be formulated, the complexity will continue to increase. In light of this, device OEMs often choose to outsource coextruded tubing manufacturing.
But how should device OEMs narrow down the decision? The most important factor is finding a contractor with an experienced and innovative engineering staff. A staff of knowledgeable engineers can not only manufacture high-quality products, but also draw on prior experience to suggest alternative materials to lower cost, raise quality, or better fit an application. Many contractors are willing to work with OEMs to develop custom solutions, including process control and new product development.
For tubing outsourcing in particular, it is very important to find a contractor that has extensive experience working with a wide range of materials. The contractor should work closely with resin suppliers to keep abreast of the newest materials. In addition, a tubing contractor must have pilot line and excess capability to optimize the material selection through multiple trials.
Another important factor in the decision making is the way the contractor works with its customers. A tubing contract manufacturer should be able to listen to the OEM and understand its needs. Once the contractor defines the OEM’s needs, it should translate the requirements directly into product specifications and explain how its engineering resources can ensure a manufactured product that meets those specifications.
One of the best ways for an OEM to determine whether a contractor will be able to meet its needs is to examine the way the contractor structures its internal teams. But first, the OEM must have a firm grasp on how involved it wants the contract manufacturer to be in the development of the finished product. OEMs will find that they benefit from having team members from business development, customer sales, or marketing departments. In addition, tubing contractors may offer value-added services, such as bonding, coating, custom packaging, or a variety of finishing options. Once an OEM identifies what it wants from a tubing manufacturer, it can begin shopping around for the best fit.
