Micro Giants: Micromolding for Medtech

Micro Giants: Micromolding for Medtech Medical Product Outsourcing article featuring Isometric Micro Molding, Inc. Micromolding for medtech is becoming serious business. The medical industry’s demands are continually challenging suppliers and manufacturers to stretch their technical competencies into areas where they may fear to tread. Doctors and surgeons urge instruments for less invasive procedures and quicker recovery times, devices are shrinking and becoming more complex, and designers seek out smaller, high-precision components with materials and tolerances that years ago were deemed impossible. To further advance minimally invasive device designs and reduce part sizes, manufacturers are turning to micromolding. By definition, micromolding is an injection molding process, but the manufactured components require magnification to view details on or within the part. It can also be defined as parts with sizes or tolerances…

Micro Molding Innovations For Medical Devices

Articles, Isometric

Micro Molding Medical Device Innovations Medical Product Outsourcing (MPO) spoke to the team at Isometric Micro Molding, Donna Bibber, Brent Hahn, and Wayne Shakal, to learn more about micro molding innovations for medical devices and the complex markets of biopharma and pharma. The big challenges of medical device miniaturization have created crucial demands on micro molders to develop new processes and methods that are outside the norm of standard injection molding. Michael Barbella from MPO discussed this impact through a variety of topics with the Isometric Micro Molding team. The Isometric experts share their 100+ years of combined knowledge on items such as what market forces fuel the need for micro molding technology, the impact of material advancements on micro molding capabilities, as well as the latest innovation in micromolding…

Thin-Walled Micro Injection Molding For Devices

Articles, Isometric

Isometric Micro Molding's micromachining of micro molds enables thin-walled micro injection molding in thermoplastic, silicone, and metal. To mold micro thin-wall devices, polymer selection, ultra-precision tooling, and knowledge of CFD (computational fluid dynamics) is critical. For micro molded devices to be small, compliant, comfortable, and/or flexible, they may require very wall thicknesses as thin as 0.002″ (50 µm). Also necessary is the analysis, tooling, processing, and handling of very thin-walled micro molded components. A growing number of medical and drug delivery devices require extremely thin walls that are consistent, pliable, and strong enough for either single-use or multiple uses over an extended period of time. Thin-walled vessels always accompany a discussion about aspect ratio (how thin and for how long it’s thin). In this article, we will highlight some examples…

Scalability of Micro-Intraocular Implants and Devices

Articles, Isometric

Scalability of Micro-Intraocular Implants and Devices Donna Bibber discusses some of these micro-intraocular implants and devices and the scalability challenges associated with each, from the perspective of a plastics engineer. Recent developments and new-to-market intra-ocular devices and implants have led to the successful treatment of a number of ophthalmological conditions of varying seriousness and complexity such as: Glaucoma Cataracts Retinal detachment Diabetic retinopathy Age-related macular degeneration Uveitis Dry-eye syndrome. Treatment of these conditions often requires collaboration between ophthalmological surgeons, pharmacologists, and micro-specific contract manufacturers. Development of these devices and implants occurs through a large number of highly focused, research-driven specialists, including and micro fabrication specialists, such as: Small, innovation-support funding programs Development companies that easily find a large marketing partner Big pharma funding the outsources of the development instead of…

How to Approach Today’s Micro Moulding Challenges Part 1: Tooling-the Enabler

Articles, Isometric

How to Approach Today’s Micro Moulding Challenges Part 1: Tooling-the Enabler Challenges in micro molding have not changed much at all in the past 20–30 years. The solutions to these challenges, however, have changed significantly. The most challenging attribute for micro molding matches up with the highest risk mitigation factor—tooling. For this reason, the top 10 micro molders in the world have in-house tooling design and fabrication capabilities. Outsourcing a micro moulding project to a micro moulder that has in-house tooling obviously mitigates the aforementioned risk significantly. Additionally, contracting such a company to not only design and fabricate but also maintain the mould for the life of the programme makes absolute sense in terms of mitigating long-term risk. This is because having made them, they know exactly how to handle…

The Four Legs That Drive MICRO Success

Articles, Isometric

The Four Legs That Drive MICRO Success The “four legs” that support Isometric Micro Molding are micro molds, micro injection molding, micro automation, and CT scanning. When a moldmaker serving injection molders of medical parts decided to get into micromolding itself, the first priority was to obtain the right equipment. For Isometric Micro Molding, Inc., New Richmond, WI, that meant buying the right injection machine, using its existing microautomation expertise for post-mold handling and assembly, and obtaining something still quite rare among custom molders—a CT scanner for process validation and in-process inspection. The firm started out in 1990 as Isometric Tool & Design Inc., building molds for producers of medical and drug-delivery components. Its medical OEM customers needed assistance with micro-sized parts, so the firm purchased a building across the street…
