AMT MIM - Innovative Applications
AMT not only applies the MIM technology to deliver consistent, reliable and quality products to our customers, but is able to synergize the MIM technology, process and material innovations to provide innovative solutions to all our customers. With our deep manufacturing expertise gained over the past 30 years, AMT has been able to deliver many innovative applications. Below are some examples:
ROBOTIC SURGICAL COMPONENTS
The MIM technology is ideal for the mass production of components used in robotic surgical systems. These robotic surgical systems typically have end effectors such as clamps, graspers, staplers, needle holders, etc, which have very complex geometries and shapes.
As such, an innovative and creative MIM process had to be introduced in manufacturing to ensure the part integrity. Using the MIM manufacuring technology not only reduces manufacturing cost, but also allows for these parts to be produced in large volumes (over 200,000 pieces per month). This is especially cruicial for end effectors used in single-use devices. Similar applications include MIS endoscopy, surgical power tools and life science systems.
COMPLEX INTER-CONNECTING CHANNELS
The MIM technology is ideal for the mass production of components such as this EPR Flow Block used in Gas Chromatography (GC) Systems. This highly complex part, with multiple through holes and inter-connecting right-angled internal channels, challenges the MIM technology.
Using an innovative manufacturing process, the dedicated internal channels prove critical in managing gas flow to and from the five ports on the parts without any leakage. With this, AMT is able to help the customer overcome their challenge and mass produce these complex geometry parts efficiently and cost-effectively. AMT was awarded the MPIF Grand Prize in 2018 for this innovation. Read about it here.
IN-CORING® - CREATION OF COMPLEX INTERNAL CHANNELS
AMT has perfected the innovative use of our In-Coring® process to manufacture metal and ceramic parts with undercut features. This innovative application allows the designer to create a single part with internal channels and undercut features without an assembly process.
Thus, the designer is able to enhance the product’s performance while achieving cost savings through mass production. A good example is this One-piece Nozzle used in the automotive Selective Catalytic Reduction (SCR) system. It was awarded the MIM Grand Prize by MPIF in 2015 as well as the EPMA Award in 2018.

CuMIM® - COPPER MIM
AMT has registered CuMIM® for the application of pure copper using the MIM technology. Utilizing the MIM technology capability allows engineers to design unconventional copper heat sink for both passive and active heat sink applications.
With pure copper material, these CuMIM® components have thermal conductivity of 320 W/mK. These copper parts can be designed with complex geometry so that the electronic component can be mounted on the copper part, and at the same time, be used for heat dissipation. Till date, AMT had delivered more than 5 million copper parts globally for use in this application in the industry.
AMT is capable of co-injecting two different materials to form an integrated two-material component. By using this innovative application, AMT can integrate hard & soft metal or magnetic & non-magnetic metal materials. By co-injecting the 2 materials together, interlocking features can be incorporated in the part, thus eliminating costly assembly operations. The product’s performance can potentially be enhanced as the two materials are manufactured as a single component.
INTEGRATION OF COMPONENTS
With MIM, multiple individual pieces can be integrated into a one-piece complex geometry component. This relieves the constraint on the designer, allowing him to focus on the functionality and performance of the product. Using this innovative strategy results in a design with better product performance, reduces part count and achieves overall cost savings. One such innovative application is the integrated component that was awarded the MIM Grand Prize by the MPIF in 2000.
THIN WALL CAPABILITY
Using innovative solutions, AMT was able to mass produce complex geometry components with very thin walls. Dealing with wall thickness of below 0.7 mm in the MIM process, our engineers had to manage distortion, shape retention, material integrity and all the dimensions during the sintering process. It was a great challenge but we finally succeeded in the mass production of this part, which won us MPIF’s Year 2002 Award of Distinction.
HERMETIC KOVAR HOUSING
This 105mm (4.14in) by 105mm (4.14in) by 1.5mm (0.06in) fiber optic MIM Housing is made of Kovar. Kovar is an expensive material with high nickel and cobalt composition, making it difficult and challenging for conventional machining. This MIM Housing defies the conventional “acceptable size”, enabling it to meet specific dimensional and hermetic requirements as well as minimize material wastage, thus achieving significant cost savings. It was awarded the Year 2003 Award of Distinction by MPIF.
