Trust Precision Microdrives to manage your development and manufacturing risks
Motor mechanisms are easy enough to prototype. But with many moving parts, they soon become a real challenge to mass-produce both cost-effectively and to a consistently high-quality standard. Precision Microdrives is a domain expert in this niche discipline.
Precision Microdrives offers a full turnkey service to prepare design inputs, develop a manufacturable solution and mass produce it.
- Our business is optimised for this very process.
- Our design engineers in Europe are in the right place, timezone and with the right language skills to work very closely with customers to develop accurate specifications and design inputs.
- Our product engineering team in Hong Kong have the language skills, supplier relationships and necessary design-for-manufacture skills to develop assemblies, with individual sub-components sourced from lower cost Asian supplier ecosystem.
- Our in-house manufacturing lines are located with our Hong Kong design team. This is very unusual for Asia, but it makes manufacturing optimisations, process controls and production documentation significantly easier.

MECHANISM CASE STUDY
Medical diagnostics instrument
Miniature X/Z axis mechanism for medical diagnostics instrument
Our customer, based in Germany, was undertaking a product refresh of an existing and well established bench-top medical diagnostics device. To increase sales, they wanted to adjust their business model to pay-per-test. Therefore they would have to loan or lease the instrument to doctor’s practices, instead of selling the machine outright.
To make this new model commercially viable within a reasonable time-frame, the target manufacturing cost of the bench-top instrument had to halved. The customer had previously sourced their motors from Swiss suppliers, but it was clear that a significant cost-down could be achieved by moving to an Asian supplier base.
However, manufacturing in Asia carries risks which the customer was only too familiar with, having suffered some reputational damage from earlier cost-down attempts. Furthermore, the machine had to operate with the same accuracy as before, although the machine (and mechanism) lifetime expectations were relaxed slightly to better reflect the less frequent use these instruments would experience in a doctors surgery compared to the previous market of centralised labs.
The customer engaged us to work with them on their redesign. Our involvement began with our European application engineers becoming familiar with the detailed operation of the instrument and understanding all the mechanical requirements and constraints.
From this basis of understanding, our European engineering team prepared a design inputs brief which was agreed and signed off with our customer.
One key part of the solution was that our design inputs showed a requirement for positional accuracy in the X axis to 25μm (½ of a human hair) and in the Z axis to 12.5μm (¼ of a human hair), despite the reduction in target cost. To achieve this we integrated encoders, home sensors and custom motion controllers into the manufactured assembly.
Development proceeded as a daily triangle of progress and communication between the customer, our application engineers in London and Europe, and our product engineering and manufacturing teams in Hong Kong.
Twelve months (and several prototype, alpha, and beta production runs) later we entered into mass production of the fully validated mechanism.
In application, the mechanism met all the key requirements of positional performance, longevity and environmental robustness. Our assembly interfaces mechanically into the customer’s instrument chassis with ease, and our integrated motion controllers interface to the instrument’s host processor, over SPI.
The customer was able to relaunch their diagnostics instrument into the market at a lower price, and with a higher profit margin, for those customers wanting to purchase it outright. They were also able launch a new pay-per-use diagnostics model to a new set of customers. In this model, the instrument was loaned, and the end-users paid a higher price for each test assay.
