In the realm of drug delivery devices, the adage ‘small is best’ resonates now more than ever.
Small is best
In the realm of drug delivery devices, the adage ‘small is best’ resonates more than ever. Accumold’s proprietary micro moulding technology is a key enabler in this regard, allowing for the production of parts with micron-sized features and tolerances that push the boundaries of what was previously thought possible. The company’s micro moulding process can produce intricate components such as thin-wall polyurethane tips for pacemakers and neurostimulators, micro- needle arrays for drug delivery, and micro-optic tips for cutting-edge imaging systems to name but a few.
Accumold excels in creating components with ultra-thin walls, a task that demands a high degree of expertise. This capability is particularly important for drug delivery devices, where thin walls can significantly reduce the volume and weight of the device, making it less intrusive for the patient while still ensuring the device’s structural integrity and functionality.

A standout achievement in Accumold’s portfolio is the development of thin-walled micro-molded cannulas. Traditionally cannulas are produced via an extrusion process, which is at the same time expensive, prone to high fall out rates, and which does not lend itself to the high volumes required by medical device OEMs for some applications.
Through a combination of expertise and persistence, Accumold can now offer the high-volume production of cannulas with simplified all-plastic bodies, and heads designed to maximise manufacturing efficiencies and product integration. The cannula design is customisable to meet specific length requirements and head design, and available materials include PP, FEP, Pebax, TPU, PC and other customer specified options. This disrupts the production of thin-walled cannulas and represents a huge step forward for medical device OEMs requiring intricate thin-walled cannulas for their innovative applications.
Understanding the material science The foundation of Accumold’s success in micro moulding lies in its absolute understanding of material science. The choice and manipulation of materials are
critical, especially when working at such small scales. Accumold utilises a wide array of materials, including PEEK, polysulfones and polyurethanes, tailored to meet the specific requirements of each device, such as biocompatibility, durability and performance under varying conditions. This expertise ensures that each component not only meets but exceeds the rigorous demands of medical device manufacturers. Accumold’s ability to produce thin discs without warping, to create micro ribs, and its mastery of the intricacies of producing micro gates demonstrates its superiority in component design and manufacturing.
Both micro ribs and micro gates are essential considerations in the design and manufacturing process of micro moulded parts, reflecting the challenges of working at such a small scale. Achieving the right balance in the design and placement of micro ribs and gates is crucial to produce high- quality, precise components that meet stringent specifications. These capabilities are essential for drug delivery devices, where precision and reliability can significantly impact the effectiveness of the treatment. Accumold’s approach to micro moulding is not just about manufacturing, it’s about partnership and customisation. The company works closely with medical device OEMs from the design phase through production, ensuring that every component is optimised for its specific application. This collaborative process is crucial for tackling the unique challenges presented by drug delivery devices, such as integrating micro components into complex assemblies or achieving the perfect balance between flexibility and rigidity in parts like cannulas. ●
