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

Super Hydrophobic and Super Hydrophilic Microfluidic Surfaces

General, Isometric

Super Hydrophobic and Super Hydrophilic Microfluidic Surfaces Polymer micro molding is a scalable and economic method of manufacturing devices with microscopic surfaces, in particular super-hydrophobic and super-hydrophilic microscopic surfaces. These surfaces are created using microscopic and repeated geometric patterns (tiny cylindrical posts and channels). These features can be fabricated to work collaboratively on the same surface to promote fluid flowing in some areas or prevent fluid flowing in other areas of a device. Applications requiring these types of microscopic surfaces include: bacteria prevention, cellular adhesion, tissue adhesion, tissue or cartilage growth promotion, frictional drag reduction, wear reduction, and seal and barrier strength applications. These surfaces also no longer require secondary coating applications which prevent handling and possible surface contamination, simplify sterilization methods, and save device costs.

Tiny Medical Devices – Designing for Success (part 2)

General, Isometric, News

Tiny Medical Devices – Designing for Success (part 2) VALIDATION Picture this – your medical device is designed and you’re ready to validate the tiniest component – the technology piece that enables your intellectual property. You dive in headfirst, knowing your part has +/- 5 micron tolerances on a plastic part. You start like any engineer would start – with a solid stack-up tolerance plan and <20% gage R&R – you should be fine, right? Consider this general micro molding rule of thumb – BEFORE you even design the injection mold. If you work backward with the numbers, you’ll have ~0.0004” total tolerance Total 10 microns = (0.000397”) Tooling = 20% of 10 microns = 0.00008” (wow, really? This is difficult to do but SO critical to hitting the final…

The Merging of Medical Device Manufacturers and the Pharmaceutical Industry

General, Isometric, News

The Merging of Medical Device Manufacturers and the Pharmaceutical Industry As product technology advances and the general demand for healthcare expands, the industry line between medical device manufacturers and pharmaceutical companies is being blurred as innovative products continue to emerge. Manufacturers are exploring new technologies that adhere to better patient compliance, improve product safety and utilize unique drug delivery methods. These new technologies include:- Small adhesive patches that are encapsulated and swallowed. Once in the body they dissolve and stick to the wall of the intestine to deliver time-released medication- Implantable devices that automatically run tests and dose medications- Transdermal patches that are embedded with micro-sized needles that deliver medication over a period of time As technology advances and healthcare treatments become more complex, the pharmaceutical and medical device industries…

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…

Tiny Medical Devices – Designing for Success

General, Isometric, News

It’s highly likely that you, as a designer, will run across a part that makes your existing molding supplier sigh, cringe or even groan. It’s times like these that you need to listen to those body sounds and seek out experienced micro manufacturers that work on tiny dust specks every day. Tiny medical devices, micro parts with challenging geometry, wall thickness, L:D or L:T ratios, or multiple materials are welcomed by those experienced and versed in the proven process of success. This “Proven Process” is broken down into a series of proven steps that will fit most tiny medical component and assembly designs. We will break down this Proven Process in five key areas, easily remembered by the letters “V.I.T.A.L”: V: ValidationI: InspectionT: ToolingA: AutomationL: Learning These vital steps will…

Secrets of Success in Micro Molding – part 2

General, Isometric, News

Micro Molding: High Aspect Ratio, Thin-Wall Micro Molded Devices Secrets of Success in Micro Molding - Part 2 The smallest components in a medical device or drug delivery device are often the enabling components of the device. Examples of these devices are Polymeric needles, catheter sheaths, microfluidic channels, endoscopic links, and PCR wells. As the components of these devices get smaller, the tolerances and wall thicknesses follow suit. Tolerances of +/- 5 microns (~+/- 0.0002”) and wall thicknesses of 25-250 microns (0.001”-0.010”) are common. Although challenges exist in creating these tolerances in both the steel mold and the micro molded components, the determining factor for wall thicknesses this thin is dependent on the aspect ratio, where the wall thickness is with respect to gate location and end of fill. The…
