Critical-use medical device manufacturers are faced with keeping pace with technological advancements and earning market share while simultaneously producing extremely precise and reliable medical products. Meeting all these challenges is a tall order, and utilizing the scientific molding process can help.
Advancements in the medical community are happening rapidly. Devices are coming to the market that address a wider range of patient issues and, in some cases, designed to work autonomously to assist staff in treatment. The intricacies of these medical advancements demand that the injection-molded plastic components they use perform with precision.
Evaluating a complex injection molder for the manufacture of critical-use medical device components isn’t narrowly defined by ISO 13485 certifications or clean room capabilities. It extends to all aspects of the potential partnership, from an injection molder’s plastics and engineering expertise to their readiness to work with and learn from you in order to achieve optimal outcomes.
The Internet of Things (IoT) – everyday objects having network connectivity for sending and receiving data – is being adopted by a number of industries, including healthcare.
As the worldwide population ages, healthcare is shifting from clinics and hospitals to in-home care and smaller, non-traditional facilities. As a result, the demand for portable medical devices that monitor diagnostic and therapeutic data and aid in treatment of certain conditions continues to increase.
Design engineers make allowances for the impact that the molding process has on plastic parts manufacturability. They carefully consider a variety of design factors like the materials chosen, the part shape and features, and the properties of the mold itself.
With the freedom to create new features – and cost-effectively achieve process efficiencies – it’s evident why many design engineers lean toward parts and products that require complex injection molding.
What isn’t always clear, however, is what goes into it. That’s probably why it’s called “complex” injection molding, which involves more than a few considerations especially at the beginning of the process. Among them is the material used to make the actual mold, in addition to the plastic materials for the part. Here are pointers to keep in mind when working through it with a molder.
Here are three things design engineers fully understand:
No pressure right? Wrong. There is a lot riding on the designer when developing complex plastic parts and products with tight tolerances, especially when they’re used in critical applications like medicine, auto manufacturing, and military among many others. Here’s why getting control of it in the design phase is a good thing, along with advice that should help take some of the pressure off.
Thinking Overmolding? Here's Why It's a Good Decision
If you’re contemplating whether to choose overmolding for your next product or part but aren’t 100 percent sure, it never hurts to think and then rethink. But to remove any shadow of doubt, here’s why overmolding will only continue to grow in popularity - and why it’s a solid choice.
What is overmolding again?
Overmolding is a unique injection molding process that results in a seamless combination of multiple materials into a single part or product. It typically includes a rigid, plastic-base component that is overlain by a thin, pliable, rubber-like thermoplastic elastomer (TPE) exterior layer or other materials. Two types of overmolding techniques used to combine the TPE layer and plastic substrate are single-shot (insert molding) and two-shot (multiple-shot molding).
