Aaron Johnson advises on how to attain pragmatically defined goals when embarking on a micro moulding project<\/strong><\/p>\n\n\n\n

For customers looking to embrace the possibilities that exist through the micro moulding of parts or components, there is a given. They need to understand what micro moulding can do in terms of stimulation of innovation, what it can deliver in terms of manufacturing efficiency, and what \u2014 above all \u2014 it can do to achieve increased functionality in parts that are often required to be smaller and smaller.<\/p>\n\n\n\n

As such, the requirement is not for lectures at conferences and articles in learned journals explaining how the micro moulding process works. Interesting as this may be for those with a penchant for \u2018serious science\u2019, when you team with a qualified micro moulder, you can leave that side of things to us. We have spent decades refining the art and science of micro moulding, we understand the complexities of moulding at the micro scale, and so this allows you and the moulder to focus on the outcomes. How can you work together with your chosen moulder to achieve your product goals, and how can you do this cost-effectively, and ultimately scale up to reliable and repeatable volume production.<\/p>\n\n\n\n

So in this article, the focus will be on what influences the ability of micro moulders to mass manufacture successfully, and what influences the process of developing micro parts and components. What is it that makes the partnership between you and your chosen micro moulder tick, and therefore achieve your goals.<\/p>\n\n\n\n

Micro moulding often necessitates the accomplishment of exacting, and sometimes seemingly impossible, tolerances. Clients may require minuscule parts, smaller than a grain of salt or with sub-micron feature sizes. When such micron tolerances are significant, the customer and micro moulding provider must form a special, more intimate partnership for product development. Consequently, the micro moulder must take charge and innovate within all aspects of the supply chain.<\/p>\n\n\n\n

Manufacturers not used to such exacting tolerances may think it impossible to mass produce parts with such minuscule dimensions and levels of accuracy, yet micro moulders do this every day. It’s especially challenging when dealing with parts as light as 0.001 grams that are needed for safety-critical applications, where zero failure rates must be observed.<\/p>\n\n\n\n

Not only do micro moulders need to make tiny parts with tiny features in a repeatable manner and achieve micron tolerances, they need to do so in a cost-effective and timely manner as well. Hence, it is imperative that we avoid having to go back to the drawing board with our designs, reviewing and changing manufacturing processes, and re-cutting already expensive and time-consuming micro-tools. \u2018Get it right the first time\u2019 is the headline over every activity.<\/p>\n\n\n\n

A successful micro moulder must understand CTQs (Critical to Quality characteristics) to manufacture parts, and these characteristics encompass moulding, assembly, and packaging as well as the functionality of the product in terms of the end-user experience.<\/p>\n\n\n\n

Value-stream thinking \u2014 from concept to order fulfilment \u2014 drives customer value. Vertical integration reduces silos and suboptimal processes by reducing the length of the value stream. Essentially, the longer the value stream, the more disconnected it becomes, and the more variables that can cause customer problems will be introduced.<\/p>\n\n\n\n

Attaining volume\u00a0<\/strong><\/p>\n\n\n\n

Customers demand the best products at a competitive cost. Voice of the Customer data allows micro moulders to identify essential characteristics which need to be monitored at production. Setting cost also includes factors such as timetables, eliminating defects and maintaining consistent supply. Micro moulders should seek to provide top quality products via validated processes with quick turnaround times. This can only be accomplished by having vertically integrated processes and validating them thoroughly.<\/p>\n\n\n\n

So, when shortlisting potential micro moulding suppliers, from a production standpoint, there are some key questions that need to be asked to ensure that the micro moulder is equipped to achieve often exacting objectives. First, do you design, build, and maintain your moulds? Second, what measurement capabilities do you have on site? Third, what are the methods of validation you use? Last but not least, what resins have you experience of using in production?<\/p>\n\n\n\n

VOCs play a significant role in the success of micro-moulded products. However, the end user isn\u2019t just the customer. There are customers throughout the entire value chain. Concerns can be raised and resolved quicker when the value stream is shorter and more centrally located.<\/p>\n\n\n\n

Assembling<\/strong><\/p>\n\n\n\n

When dealing with miniaturised plastic parts and components, it is crucial that assembly is brought up early in the design process. This calls for an effective collaboration between OEM and micro moulder. The manual assembly of micro components is usually too expensive and very precise sub-micron tolerances can’t be achieved by human hands \u2013 thus automated assembly is necessary. This also means that OEMs have to pick a micro moulding provider that is capable of recognising the principles of micro assembly as well as achieving extreme exactitude.<\/p>\n\n\n\n

A laser-like focus on design for micro manufacturing (DfMM) is essential for the success of any product development process, including assembly. Micro moulding projects present a unique challenge in that they involve more variables and require more precision than typical projects. It can be difficult to feed, inspect and manipulate these parts without causing damage, as well as capturing and orientating them after moulding. Capturing parts at the mould ejection stage coupled with immediate assembly is often the most effective way to assemble micro moulded parts with minimal waste.<\/p>\n\n\n\n

In order to maintain margins and provide a product to the market at an affordable price, such considerations should all be bottomed out at the design stage.<\/p>\n\n\n

\n
\"\"<\/a>
A successful micro moulder must understand CTQs (Critical to Quality characteristics) to manufacture parts<\/figcaption><\/figure>\n<\/div>\n\n\n

What this means?<\/strong><\/p>\n\n\n\n

Before embarking on a micro moulding project, customers should focus on the mould design, mould build, and quality measuring capabilities of the vendor they are engaging to mould their parts.\u00a0 If moulders lack the ability to design, build, and measure high-quality moulds to extremely tight tolerances, they will struggle to produce consistently high-quality parts to tight tolerances.\u00a0 Producing products to specifications that only allow microns of variations to a specification is much more challenging than producing a product with significantly larger variation allowances.\u00a0 A poorly designed and built tool can eat up your entire variation before you even mould a part, essentially killing the project.<\/p>\n\n\n\n

So, focus on your chosen supplier\u2019s capabilities in these areas rather than worrying about the way the micro moulding process works per se. It should be a given that a micro moulder can micro mould, and therefore take away the headache of you needing to understand the process. It is not a given, however, that a micro moulder can work with you and have the capabilities beyond moulding to guarantee product success and volume production.<\/p>\n\n\n\n
