MD&M Minneapolis Tech Talk Preview – High-Aspect-Ratio Molding Reaches New Extremes

MD&M Minneapolis Tech Talk Preview – High-Aspect-Ratio Molding Reaches New Extremes Editor-in-chief of Design News, Daphne Allen, previews Isometric’s upcoming MD&M Minneapolis Tech talk. Daphne Allen, editor-in-chief of Design News recently discussed Isometric’s upcoming presentation at MD&M Minneapolis, “High-Aspect-Ratio Molding Reaches New Extremes”. The talk will be given by Isometric’s VP of Business Development & Strategy, Brent Hahn, on Tuesday, October 10 at 2:00PM in the Expo Hall Tech Theater. Allen wrote “Hahn will explore how a variety of resins—from traditional, high-flow materials to difficult-to-process materials such as PEEK and FEP—can be used to create fully filled cannula and catheter tips without flash and without secondary operations that measure 0.001 in. (25 microns) and reach extreme aspect ratios (L/T) as high as 400:1.” VIEW ARTICLE LEARN MORE ABOUT MD&M MINNEAPOLIS

Isometric’s Microns Matter® PFMEA Process

General, White Papers

Isometric's Microns Matter® PFMEA Process Figure 1.1 Isometric Micro Molding “Average” Tolerance Risk Assessment Strategy Each phase of Isometric's Microns Matter® PFMEA process allows for the accurate estimation of percentage micron tolerance risks, which mitigates risks during each phase. Truly, components and devices with micron tolerances can only be successfully manufactured by applying years of tooling and plastics engineering experience. These phases include: ULTRA-PRECISION TOOLING METROLOGY MATERIAL DRYING MATERIAL LOT TO LOT VARIATION MICRO INJECTION MOLDING PROCESS The histogram in Figure 1.1 shows the average percentage error in each of these phases for a molded part with a tolerance of +/- 8 microns (16 microns total) and a process capability index (Cpk) of 1.33. From a risk mitigation standpoint, it's critical to select a micro molding partner with a vertically…

Micro Ophthalmic Ocular Implants

Articles, Isometric

Micro Ophthalmic Ocular Implants Donna Bibber shares insight about micro ophthalmic ocular implants and the continued impact of micro mold manufacturing on worldwide growth in the next five years. Micro ophthalmic and intraocular implants continue to be one of the largest and fastest-growing global micro medical and pharma micro device market sectors. Driven by a baby boomer aging population, technology innovations, and vast, rapidly emerging markets in China and India, the ophthalmic devices sector is expected to attain a double-digit growth. Age-related eye diseases such as cataracts, diabetic retinopathy, glaucoma and macular degeneration (to name only a few) continue to cause significant or complete loss of vision. Since ophthalmic and intraocular implants are largely made up of many micro-sized and highly precise components and assemblies, it's easy to understand the…

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…

5 Steps to Micro Molding Success

White Papers

Microns Matter® 5 Steps to Micro Molding Success With over 30 years of experience in micro injection molding, Isometric Micro Molding has developed a unique 5-step risk assessment strategy called, "Microns Matter®". This proven process is especially important for the successful manufacturing of medical devices, from the development stage to high-volume production of these critical-to-function micro molded devices. Vertical integration and transparency are key to our unique risk mitigation. We've repeatedly heard from OEMs that it's not uncommon for micro-molding suppliers to say that the work is “proprietary”, contains “trade secrets” or, “you can’t see that part of the process”. This level of secrecy leaves a large gap in design history files, which can result in increased design and clinical trial resources, time, and, in many cases, a restart with…

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…

What is a Brain Perfusion Phantom?

General, Isometric, News

A brain perfusion phantom is a 3D printed plastic brain that allows surgeons to practice mechanical thrombectomies. A mechanical thrombectomy is a procedure where surgeons thread a wire from the chest, through the neck, and into the head to pull clots out of the brain of a stroke victim. As you can imagine, there are a lot of risks associated with this procedure, like the wire loosening another clot from the wall of the artery and it lodges in the heart, lung, or brain. Computer simulations of this procedure exist but are extremely expensive to purchase for med students to use. And as you can imagine, neurosurgeons need extensive training on this procedure before working on a human being. That is why a UConn Health radiologist and a medical physicist…

Micro Scale Manufacturing

Isometric, News

The Big Trend For Small Devices is Drug Delivery One day in the late 1980s, Donna Bibber looked over the shoulder of a “mad scientist” colleague at Corning Life Sciences – he was working on lab-on-a-chip technology, and Bibber realized that it could be a game-changer. She is now Vice President of Isometric Micro Molding, which addresses the growing market need for expertise in device miniaturization. Isometric specializes in making and assembling tiny components, primarily for medical device companies. Some of the work is quite experimental – only around one approach in ten gets taken to the next level – and, as Bibber puts it, they have to “kiss a lot of frogs.” Bibber divulges the current trends and challenges in the world of the production of micro-scale drug delivery…
