Speak to an Engineer

Improving the design and specifications of the metal injection mould early in the MIM process is crucial for enhancing overall part quality and ensuring optimal performance.

Enhanced Product Quality

Enhancing parts through Design for Manufacturing (DFM) reduces the risk of defects and ensures greater product reliability.

Holes and slots can be easily produced with MIM, offering reduced part mass, improved wall thickness uniformity and minimal additional cost, with perpendicular holes being the most cost-effective.

MIM readily creates external undercuts, increasing design flexibility. Internal undercuts are possible but may require complex solutions and engineering expertise.

Undercuts

Integrated threads, both internal (using unscrewing cores) and external (moulded, sometimes requiring a parting line flat), streamline production and improve engagement.

MIM allows detailed features such as knurling, lettering, logos and date coding to be added directly to components without affecting cost, demonstrating its versatility in complex metal part design.

Heat treating enhances the strength and hardness of MIM parts. Carbon, alloying elements and porosity influence hardening.

<p>Sustainability in manufacturing is often associated with large-scale changes, but at OptiMIM, it’s embedded directly into 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 thoughtful 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 steps 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 for 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 smokestacks. 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 Trade-Offs</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 larger 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>

How OptiMIM Builds Sustainability into Metal Injection Moulding

<p>When a component first enters production, the top priority is manufacturing a sound, high-performing part—many processes can achieve that. However, over the life of a project, effectively scaling the production process at the lowest total cost becomes increasingly critical. For manufacturing small, complex components at scale, <a href="/metal-injection-molding/process" target="_self">metal injection moulding (MIM)</a> is the most efficient process.</p><p>OptiMIM has expertise in taking projects from the drawing board through to mass production. The metal injection moulding process is well suited to scalability through automation, large batch capacity and relatively low upfront investment. Its engineers are also experts in streamlining supply chains and validation processes.  </p><p>Sign up for a free on-demand webinar to learn how to leverage the MIM process to <a href="/metal-injection-molding/benefits" target="_self">manufacture components efficiently</a> from the prototyping stage through to mass production.&nbsp;</p><p><strong>The webinar covers:</strong></p><ul><li>Streamlining regulatory validations, such as FDA approval</li><li>Scaling MIM manufacturing at a lower total cost</li><li>Shortening your supply chain through automation and part consolidation</li><li>MIM case studies</li></ul><p><strong>Complete the form to sign up for our free on-demand webinar:</strong></p>
