Micro molding for critical applications requires extreme precision and a consistent, proven process. After all, micro-sized components are often the key enabling elements of Class II or Class III medical devices and drug delivery devices which, because of their size, often require micron-level tolerances. With 30 years’ experience in micro injection molding, Isometric Micro Molding has developed a best-practice risk assessment strategy called “Microns Matter®”, which is used for the development and high-volume production of critical-to-function micro molded devices.
The Microns Matter® process follows a Japanese-like strategy — essentially, “plan, plan, plan, execute”. The axiom “fail to plan, plan to fail” is never more accurate than when it’s applied to micro manufacturing projects. But the failure of planning, and resultant re-iterations of designs, re-assessment of manufacturing protocols, and adjustment or reworking of tooling are not just annoying, they are sometimes catastrophic in respect of time and cost and can be the difference between project success and project failure. Measure twice, cut once!
Micro molded parts are often the size of a fingerprint crease, so they require minimal tool steel cutting time compared with macro-sized parts. Because of this, a disproportionate emphasis needs to be placed on the “planning, planning and planning” setup of critical equipment that’s required to make an accurate micro part or component in a timely and cost-effective fashion.
Isometric Micro Molding is committed to meeting or exceeding customer expectations through the rigorous, continual improvement of our processes. This dedication results in enhanced product quality, optimal support, and on-time delivery. When coupled with our company-wide commitment to our quality management system, we are successful with the complex and exacting projects from our medical device and drug delivery device customers.
