Mikrotech’s success as a full-service micro manufacturer is using equipment specifically designed for micro machining. We strategically collaborate with machining partners to offer our customers a more cost-effective and timely option for prototype and low-volume components. Micro machining has twice the precision and spindle speed as conventional machining equipment, which allows us to produce high-quality machined components even with difficult-to-machine plastics. We can take a solid model or CAD drawing to a finished component in under three weeks.
Micro machining can also provide an excellent, cost-effective solution during the initial stages of the product development cycle. For instance, the design of a medical device for minimally invasive surgery often undergoes multiple iterations before the final appearance and functionality of the product is complete. Micro machining requires little if any tooling costs during the design iterations.
Micro machining is also suitable for adding features to a micro molded component. Often, the complexity of a component makes the cost of micro molding tooling cost prohibitive. It may also increase the complexity of the mold tool resulting in high maintenance and operating costs.
One way to address this issue is micro molding as much of the geometry of the component as possible and performing secondary micro machining operations to complete the finished product. The designer can capture all features required and obtain a majority of the benefits of lower-cost micro molding.
Our micro machining technology has a range of abilities that include:
- High-performance plastics such as PEEK, PPS, PEI, and LCP
- Plastics such as ABS, PAI (Torlon), PC, PMMA, and PTFE
- Dimensional tolerances of +/- .005 mm (.0002 in)
- Accurate components weighing less than 0.1 g (.0035 oz)
- Implantable and non-implantable components
- Wall thicknesses as low as .08 mm (.003 in)
- Lens (optical) quality components
- Vapor polishing and deburring
- Annealing (stress relieving)
Some of the most common micro machining materials we work with include (but are not limited to):
Micro Machining FAQs
What materials can be used in micro machining?
We use high-performance thermoplastic materials such as PEEK, PPS, PEI, and LCP; and other plastics including ABS, PAI, PC, PMMA, and PTFE. We can also work with magnetic materials used in gear assemblies; and custom and proprietary compounds of our customers.
Does Mikrotech offer prototype machining components?
Yes! We’ve done anything from quantities of one part to 1,000 parts for prototype testing quantities. If you just want to make one part to test the design, we can do that, too.
Do you offer production quantities for micro machining?
Yes! Sometimes a customer’s production quantities aren’t high enough to make the transition to molding and the capital investment doesn’t justify manufacturing a mold for the part. That’s why we offer the higher machining quantities until they reach the threshold that would make molding cost effective.
Can a machined component be transferred to molding?
For customers with low quantities, the component will get machined first. As quantities increase, it becomes more cost effective to do molding. We can recommend design modifications early in the process to determine whether it’s feasible to machine first, and then mold later on for larger quantities. Maintaining a consistent design also reduces the risk of failure of the part in the application.
