For companies that require tight-tolerance, critical-use plastic injection molding capabilities, it's important to partner with a supplier that can consistently deliver quality products and value-added services to support these solutions. When evaluating your list of potential full-service injection molders, however, you may ask yourself, "Do I want a partner that is specialized or diversified?"

From a supplier and customer viewpoint, there can be risks involved in choosing a specialized molder, and the guideline below explains why.

Total delivered cost (TDC) is the amount of money it takes for a company to manufacture and deliver a product. The definition sounds simple enough, yet all that TDC entails — sourcing raw materials, manufacturing bulk and intermediate products, finished goods packaging, inventory holding, transportation, distribution, and final delivery — reveals its complexity and considerable impact on the bottom line.

Quality is an important benchmark in all aspects of an injection molding project, and rightfully so. Producing high-quality plastic parts is always the goal, but how often do you stop to consider what a supplier misstep, a materials snafu or a process miscalculation could do to a project overall? Poor quality — in any form and to any degree — can have far-reaching impact. The solution is partnering with an experienced injection molder that can help you keep quality at the forefront in every aspect of a project:

For all practical purposes, supply chains are extensions of an OEM’s capabilities and services. Injection molders on an OEM’s approved supplier list must demonstrate certain core competencies that help address — and alleviate — OEM concerns around quality, cost, reliability and a host of other factors that could influence outcomes and, ultimately, their reputation and bottom line.

Manufacturers are always looking for practical ways to streamline product design, engineering and production, leading many to supplier consolidation. Reasons for this make good business sense, and include reduced development time and associated costs, improved logistics, and a single point of contact. 

In the case of custom injection molding, however, even these compelling business reasons may not be enough to overcome the difficulty of finding a single supplier that possesses the injection molding expertise and capabilities to optimize your process and meet your needs.

Always have a Plan B. That’s something we’re taught early-on in life, but the truth is, it’s easy to become complacent and not have a backup plan. For manufacturers, this can be particularly risky since, so often, unanticipated events out of their direct control on the supply side of production can cause turmoil.

The medical industry is a complex network of skilled professionals, facilities and equipment that provides ongoing, immediate — and, at times, emergency — services to preserve and protect human health. It carries a unique importance, and medical device and equipment manufacturers share in shouldering that responsibility by taking all necessary precautions to help ensure the critical-use products they provide are defect-free and consistently reliable.

An approved vendor list isn’t meant to be static, and if you’re treating yours like it’s written in stone, you may be doing yourself and your business a disservice.

Critically evaluating vendor performance on a regular basis not only helps you identify and weed out those that aren’t consistently meeting expectations, it also provides an opportunity for vendor consolidation.

The complexities of your critical use medical application require you to assemble and manage a supply chain that optimizes expertise and efficiencies from a number of sources. Focusing on singular areas, like injection molding, is important to the successful performance and reliability of your medical components, but a broader view of the project must also be taken to leverage the expertise of your suppliers in order to streamline processes and achieve a faster time to market.
