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…

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. Talk to our plastics…

Micro Medical Device Chips Deliver Pinpoint Pain-Relieving Therapies

Isometric, News

Micro Medical Device Chips Deliver Pinpoint Pain-Relieving Therapies Often times in micro manufacturing, we use what has been successful in nature. Commonly, natural pressure, or piezoelectric, capillary, and venture-type actions utilize pressure and surface tension to move fluids to and through implants and needles to move blood or active ingredients to direct places in the body. Isometric Micro Molding, Inc. molds parts the size of salt crystals that are scalable and economically feasible for the treatment of intraocular, cardio, and neurological disorders such as Parkinson’s, Alzheimer’s, Glaucoma, Macular Degeneration, diabetes, oncology skin treatment, and cardiac disease.

Eye, Blood, and Joint Fluid Traveling Devices- Where Micro Molding Meets 3D Printing

Isometric, News

Eye, Blood, and Joint Fluid Traveling Devices- Where Micro Molding Meets 3D Printing It’s long been known that micro vs. macro physics have thwarted some efforts to create micro components and assemblies. The study of Newtonian (fixed viscosity) and Non-Newtonian fluids (variable viscosity) fluids have an unique impact on developing and scaling drug delivery devices and body-fluid flow. Non-Newtonian fluids can be found in the blood, the eye, and in joint fluid and micro implants, swallowable devices, and tiny motion devices can be helped along with a change in viscosity. This research also brings 3d printing and micro molding technologies together, which will happen more and more as the 3d printing and materials very quickly are developed. Isometric is excited to be positioned well in this market space. Kudos to Max…

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…
