<p>With the abundance of metalworking solutions available, engineers frequently enquire about MIM (Metal Injection Moulding) and its ideal applications. MIM combines thermoplastic injection moulding and powder metallurgy to create intricate, dense, high-performing metal components. However, the key question is when MIM delivers the highest ROI compared with other processes for a specific project.</p><p>The suitability of a part for MIM is primarily determined by factors such as size, weight and volume. Overly large parts consume excessive space in MIM moulds, affecting cost-effectiveness. Nonetheless, part complexity often determines the potential ROI manufacturers can achieve with MIM.</p><h2>Part sizes for metal injection moulding</h2><p>The limiting factors for the <a href="/metal-injection-molding/process" target="_self">metal injection moulding process</a> are determined by the mould's size capacity and the amount of raw material required per component. For these reasons, MIM components are typically smaller than the palm of an average hand and weigh under 60 grams.</p><h3>Metal injection moulding feedstock cost</h3><p>MIM feedstock is a combination of very fine, <a href="/materials/special-and-custom-materials" target="_self">customisable metal powders</a> and polymers, which tends to be more expensive than typical molten casting alloys. As a result, material cost is one of the biggest limiting factors in the MIM decision-making process. At <a href="/about-us/company-overview" target="_self">OptiMIM</a>, our engineering team can help optimise your component’s features to minimise wall thickness for the most ergonomic design.</p><p>Mould space and materials limit most MIM components to less than 3 inches in length, but what the MIM process lacks in size capacity, <strong>it more than makes up for in part complexity, repeatability and scalability.</strong></p><h3>Take advantage of increased complexity for maximum ROI</h3><p>While MIM tooling has a higher initial cost than competitors that machine wrought stock, machine investment castings and machine conventional permanent mouldings, MIM part cost remains constant with additional complexity and moulded features.</p><p>MIM can achieve intricate features such as dovetails, slots, undercuts, fins, internal and external threads, or complex curved surfaces—just to name a few. MIM can also produce cylindrical parts with unique geometries and greater length-to-diameter ratios than most other casting technologies, as well as consolidate several components into one for better functionality.</p>

Sustainable manufacturing through advanced metal injection moulding

<p>Metal injection moulding (MIM) is a technology that addresses many current manufacturing challenges. OptiMIM utilises the injection moulding process to produce net-shape parts, ideal for high-performance applications demanding exceptional density, strength and corrosion resistance. These parts consistently outperform industry standards in mechanical and physical properties. <a href="/additional-capabilities/engineering" target="_self">Designing for metal injection moulding</a> requires careful consideration of several factors to ensure project success. Continue reading to explore the distinctive variables incorporated into our award-winning components.</p><h2>Metal injection moulding design – moulding variables</h2><p>Designing for metal injection moulding requires careful consideration of various factors. The mould can be a two-plate or three-plate design. When designing the part, it is essential to determine the placement of details and features, such as gating and gate location. In some cases, a single gate or multiple gates may be necessary, depending on the part's geometry.</p><h3>Parting lines</h3><p>It is also crucial to consider the parting line and parting line witness. Every part has a parting line related to the moulding process. However, it is important to be mindful of the application and understand how the parting line's location might affect the part's form, fit or function. Ideally, the parting line should not be on a functional surface.</p><h3>Ejector marks</h3><p>Another important consideration is ejector marks. All parts must be ejected from the mould, so the ejector location must be carefully evaluated in relation to the part's function. In certain instances, sleeve ejection can be used to minimise or eliminate ejector marks.</p><h3>Wall features &amp; wall thickness</h3><p>Additional factors to consider include thin wall features, especially those measuring 0.020 inches or less in thickness. When injecting thin features into a mould, there is a risk of breakage if the ejection process is not performed correctly. Our engineers carefully evaluate these factors and collaborate with clients prior to developing new programmes.</p><p>For the full list of moulding variables, download OptiMIM’s MIM Design webinar!</p><h2>Metal injection moulding design considerations</h2><p>After we move beyond moulding variables, we begin looking at <a href="/additional-capabilities/part-improvement" target="_self">metal injection moulding design considerations</a>. Due to the complexity of the MIM process, there are quite a few design features that need to be addressed at each stage.</p><h3>Drag effect</h3><p>The drag effect is simply the fact that, inherent to the MIM process, a part shrinks on the tiles when placed into our sintering ovens. Keep in mind from the MIM 101 webinar that, on average, a MIM part will shrink about 20 percent. Specific shrinkage rates depend on the grade of material, and our engineering team designs the part with shrinkage factored in.</p><h3>Sag effect</h3><p>The second effect that occurs during the sintering process is the sag effect. During sintering, parts become relatively soft and, because of gravity, cantilevered or unsupported features tend to droop or sag. To design for the sag effect, we create a design that counters the effects of gravity. We can add special supports or ceramics, which could be individual blocks, or custom-machine ceramics to maintain those unsupported features.</p><p>Another option is working with you to modify your design to accommodate this goal without adding any additional costs. We look to add features such as gussets to the part. Again, this would be ideal as long as it does not affect the form, fit or function of your application.</p><h3>Draft angles</h3><p>The design characteristics for metal injection moulding are very similar to plastic injection moulding. However, the main exception is the requirement for draft angles. In most cases for metal injection moulding, we do not require any draft angles at all. It is a rare requirement.</p><p>The only time we might require a draft angle is if we have a high aspect ratio feature and need to pull the mould, such as a thin wall section or a long core pin. We may introduce a half-a-degree draft for additional relief, but for the most part, we do not require a draft angle. The reason is that we have paraffin wax in the feedstock, and that wax acts as a mould release agent, allowing us to have, for the most part, straight holes in the mould. Very little shrinkage occurs at the moulding stage. For that reason, a draft angle is not required.</p><h3>Wall thickness</h3><p>Another aspect of metal injection moulding that is very similar to plastic injection moulding is uniform wall thickness. An ideal MIM part has similar wall thickness throughout so that we can control shrinkage variability.</p><h3>Undercuts</h3><p>At OptiMIM, we design components with a collapsible core, a mould feature that enables us to incorporate undercuts directly into the moulding process, thereby reducing the need for secondary operations and costs. Undercuts are often impractical or challenging with other manufacturing methods, but they are achievable with metal injection moulding. Consulting with our engineering team prior to designing for undercuts is highly recommended.</p><p>To learn more about mould and design variables for the metal injection moulding process, download our free webinar. We will discuss the above topics in more detail and cover more on:</p><ul><li>Knurling</li><li>Custom feedstock</li><li>Gating</li><li>Secondary operations</li><li>Solving functional or assembly issues</li><li>And more! </li></ul><p>OptiMIM works with many of the world’s most demanding manufacturers—from <a href="/industries/medical" target="_self">medical</a> and <a href="/industries/defense" target="_self">defence</a> to <a href="/industries/automotive" target="_self">automotive</a> and <a href="/industries/consumer-electronics" target="_self">consumer electronics</a>.

Designing for metal injection moulding

<h2>Advancing spinal surgery through smarter manufacturing</h2><p>Spinal procedures are inherently complex, requiring precise placement of surgical instruments and exceptional dexterity. Even when complications are avoided, traditional methods often require forceful manipulation, resulting in longer and more painful recovery periods for patients.</p><p>Spine Wave, Inc., a Connecticut-based medical device company founded in 2001, is addressing these challenges by developing innovative surgical solutions specifically designed for spinal treatments.</p><h2>Engineering innovation: the Velocity® Expandable Interbody Device</h2><p>Among Spine Wave’s standout innovations is the Velocity® Expandable Interbody Device, which uses groundbreaking expandable implant technology. The device features a small spacer inserted into the spine that expands once in place, allowing improved stability and alignment.</p><p>Velocity® is deployed using a handheld gun loaded with a cartridge containing the implant. Surgeons activate the trigger to insert the contents into the surgical site and can load multiple cartridges per procedure — seamlessly completing several implant expansions within a single operation.</p><p>However, as Manufacturing Engineer Zachary Sniffen and Senior Quality Engineer John Kapp emphasise, every step leading up to implantation must be equally precise to ensure the success of the procedure.</p><h2>Solving shipping and assembly challenges</h2><p>While Spine Wave is known for innovation in spinal technologies, getting its next-generation instruments safely and efficiently into surgeons’ hands was a costly logistical challenge. Components required extra care during shipping to avoid misalignment or damage before surgery.</p><p>To overcome this, Spine Wave’s engineers turned to OptiMIM for a more cost-effective, reliable solution that would ensure smooth delivery straight out of the box.</p><p>Preparing the Velocity® device for surgery involves removing cartridges from sterile packaging and snapping them onto the delivery gun. As Sniffen explains, “Surgeons could have trouble mating the gun to the cartridge if components inside became misaligned during shipping.”</p><p>To solve this, Spine Wave developed a shipping lock, a compact, clip-like piece that holds components securely in place during transport. When the cartridge is loaded onto the gun, the mechanism automatically disengages, allowing smooth, uninterrupted assembly in the operating theatre.</p><h2>Transitioning from machined parts to MIM components</h2><p>Initially, the shipping locks were machined from raw bar stock, a process that delivered precision but at a high cost. “We had to change processes, and we knew metal injection moulding would give us a cost reduction,” says Kapp. That is when the team contacted OptiMIM.</p><p>“Complex geometries and intricately shaped features make <a href="/industries/medical" target="_self">medical devices</a> a great fit for the MIM process,” explains OptiMIM. “Spine Wave could have spent six to seven times more machining this part than producing it through MIM.”</p><p>OptiMIM collaborated closely with Spine Wave’s engineers to optimise manufacturability, achieve tighter tolerances, and deliver consistent quality at scale. “We saw the best opportunity for a quality part from OptiMIM — and their willingness to work with us on our design intent,” Sniffen says.</p><p>Ultimately, the switch to MIM not only reduced costs but also opened the door to greater production efficiency and scalability. In fact, Spine Wave later extended the shipping lock’s application to a second product. “It paid for itself fairly quickly,” says Sniffen. “It was pretty much a no-brainer for us.”</p><h2>The OptiMIM partnership: experience, expertise and collaboration</h2><p>Transitioning to MIM presented unique engineering challenges. “With projecting features such as the shipping lock posts, the injection moulding process always presents challenges with cooling, flexing, and bowing,” says Kapp.</p><p>To address this, Spine Wave partnered with OptiMIM’s experts through a <a href="/additional-capabilities/engineering" target="_self">Design for Manufacturing (DFM)</a> approach, optimising the part for MIM production and working hands-on at OptiMIM’s Portland, Oregon facility.</p><p>During development, Spine Wave’s engineers discovered (or rediscovered) <a href="/about-us/company-overview" target="_self">OptiMIM’s century-long legacy of in-house MIM expertise</a>. Kapp recalls working with the company years earlier under its original name, Kinetics: “They’ve done some very technically challenging work. It was the right choice for this project.”</p><p>The collaboration delivered measurable success:</p><ul><li><strong>Target dates met</strong></li><li><strong>Significant cost reduction</strong></li><li><strong>Seamless transition</strong> from the machined part to MIM</li></ul><p>“For a quality engineer, having nothing to report is a resounding endorsement,” Kapp says.</p><h2>A trusted partner in precision manufacturing</h2><p>“The engineers at OptiMIM had the foresight to see a potential issue on a susceptible part that did not appear during development,” Kapp adds. “Because of their expertise, we were able to circumvent the issue and avoid any inventory delays.”</p><p>By combining deep MIM experience, collaborative engineering, and design optimisation, OptiMIM helped Spine Wave achieve cost-effective, high-performance results — proving how transitioning from machining to MIM can enhance precision, reduce cost, and improve manufacturability across the medical device industry.</p>

<p>At OptiMIM, a key differentiator is its customisable feedstock, produced in-house. This feedstock is made by combining very fine metal powders with thermoplastic and wax binders in a precise recipe to achieve between 95 and 100% theoretical density and close tolerances across high-volume production runs.</p><p>Producing <a href="/materials" target="_self">metal injection moulding materials</a> to achieve higher strength and density sounds good on paper—but that only begins to cover the problems that can be solved with proprietary feedstock capabilities.</p><p>In this webinar, MetalSolutions series veteran John O’Donnell and OptiMIM Engineering and Tooling Manager Steve LeBlanc will cover the many ways MIM materials can solve common manufacturing problems, including:</p><ul><li>Modifying materials to suit project requirements</li><li>Creating custom materials to suit project requirements</li><li>Achieving higher strength, density and durability than with powder metallurgy</li><li>Shortening your supply chain</li><li>Increasing design freedom, and more!</li></ul><p><strong>Please complete the form to download our free on-demand webinar.</strong></p>

How to solve problems with MIM materials | OptiMIM webinar

How to solve problems with MIM materials

<p>Sustainability in manufacturing is often associated with large-scale changes, but at OptiMIM, it is embedded directly in the details of the <a href="/metal-injection-molding/process" target="_self">metal injection moulding (MIM) process</a> itself. Insights shared by Senior Process Engineer Matthew Jones reveal how considered engineering decisions can reduce waste, eliminate hazardous materials and create more efficient outcomes, all without compromising performance or cost.</p><h2>Reducing environmental impact through innovative MIM processes</h2><p>Metal injection moulding is a process that combines fine metal powders with binders such as plastic and wax to create complex parts. These moulded “green parts” are then processed through several stages, including dewaxing, debinding and sintering, to achieve their final shape and material properties. </p><p>While this process is widely used across the industry, OptiMIM has re-engineered key stages to minimise environmental impact.</p><h3>Eliminating hazardous solvents</h3><p>One of the most <a href="/about-us/sustainability" target="_self">significant sustainability advantages</a> comes from OptiMIM’s proprietary dewaxing process. Instead of using chemical solvents, which are common in the industry and present serious handling and disposal challenges, OptiMIM uses a thermal method to remove wax from parts. </p><p>This approach delivers two key benefits:</p><ul><li><strong>No hazardous chemicals</strong>: Eliminating solvent use reduces environmental risk and improves workplace safety. </li><li><strong>Lower scrap rates</strong>: Solvent-based methods can damage parts, leading to scrap rates of around 10%. OptiMIM’s process avoids this issue entirely. </li></ul><p>By designing its own specialised ovens, OptiMIM has created a cleaner, more efficient alternative that aligns with strict environmental standards. These ovens are engineered specifically to support the thermal process, allowing precise temperature control and consistent wax removal without introducing contaminants or stressing the parts. </p><p>As a result, the process not only eliminates the need for hazardous solvents but also enhances overall production reliability. This level of control reduces variability, minimises defects and supports higher-quality output, reinforcing both the environmental and operational advantages of OptiMIM’s approach.</p><h2>Maximising resource recovery in the metal injection moulding process</h2><p>OptiMIM extends its sustainability efforts beyond waste reduction by actively repurposing by-products into valuable resources. Its dewaxing process generates paraffin wax with a purity of 99.99%, which, while not yet reused at scale, offers potential for practical applications such as fire starters.</p><p>During the debinding phase, plastic binders are converted into hydrocarbon by-products that are captured rather than discarded. These materials are then blended with oil to produce a reusable fuel, ultimately sold for use as maritime bunker fuel. This approach not only reduces waste but also creates an additional value stream from existing processes.</p><p>Together, these practices reflect a circular approach that transforms process by-products into meaningful, usable outputs, reinforcing OptiMIM’s commitment to both environmental responsibility and operational efficiency.</p><h3>Controlled processing for consistent, cleaner results </h3><p>The debinding and sintering stages are carefully optimised to ensure both efficiency and product quality. By precisely controlling temperature increases and gas flow, OptiMIM enables the effective breakdown of materials while minimising the risk of defects. This level of process control supports consistent outcomes and reduces the need for rework or scrap.</p><p>Equally notable is what is absent from the process. As one visitor reportedly observed during a facility tour, there are no chimney stacks. This absence underscores a broader commitment to reducing emissions and maintaining a cleaner manufacturing footprint, reinforcing OptiMIM’s focus on environmentally responsible operations.</p><h3>In-house material control for better performance and efficiency </h3><p>Unlike many competitors who rely entirely on pre-made feedstock, OptiMIM formulates and <a href="/materials" target="_self">produces about half of its own material in-house</a>. This level of control allows the company to optimise the balance of metal, plastic and wax, improving not only performance but also process efficiency and waste reduction.</p><h3>Sustainability without compromises</h3><p>What makes OptiMIM’s approach especially notable is that these environmental benefits do not come at the expense of quality or cost. In fact, the company’s proprietary processes often result in improved <a href="/materials/metal-selector-tool" target="_self">material properties</a> while maintaining competitive pricing. </p><p>This reinforces an important point: sustainability and performance can go hand in hand when innovation is built into the process.</p><h3>Responsible manufacturing built into every process</h3><p>These process-level innovations reflect OptiMIM’s broader sustainability philosophy—one focused on reducing environmental impact, improving efficiency and responsibly managing resources across operations.</p><p>By eliminating hazardous chemicals, minimising waste and finding value in by-products, OptiMIM demonstrates how advanced manufacturing can support both business goals and environmental responsibility.</p>
