Microfluidic technologies are transforming modern diagnostics, biotechnology, and analytical chemistry. Many of these systems rely on microfluidic chips containing microscopic channels that guide small volumes of liquids for chemical reactions, biological assays, or sample analysis. As microfluidic products move from laboratory prototypes to commercial applications, manufacturers face a key challenge: how to produce microfluidic devices at industrial scale while maintaining

Creating microfluidic devices is a precise and demanding engineering process. Many teams begin with microfluidics fabrication methods such as PDMS casting, micro milling, laser machining, or 3D printing. These techniques are ideal for validating flow behavior and testing early designs. However, when the device moves beyond prototyping and toward commercial production, fabrication alone is no longer enough. At that stage, micro injection molding becomes critical. This article

Microfluidic prototyping serves as a critical foundation for transitioning lab-on-a-chip systems and droplet microfluidics applications from early-stage research to scalable production. As these systems mature beyond academic research into clinical diagnostics, biopharmaceutical development, and environmental sensing, the requirement for prototyping methods aligned with industrial manufacturing constraints becomes essential. This article outlines current challenges in microfl

Thermoplastics vs Glass for Microfluidic Manufacturing

Creating microfluidic chips is a difficult and precise process. Manufacturers have several options available for creating small channels, holes, and V-grooves. While some use chip making techniques like embossing, photolithography, or micro 3D printing for these purposes, micro milling microfluidic chips is still the preferred option for prototyping, though not for serial production. However, micro milling is useful for much more than making chips. Manufacturers can also use

The need for tiny, even micron-scale parts has increased over the past few years, and thus the relevance of micro technologies is increasing due to the drive toward miniaturization. Because of microinjection molding capacity for mass production and relatively cheap production costs, it may be considered one of the fundamental technologies for mass micro manufacturing (replication). Micro injection molding involves shaping micron-level geometries to a plastic product with the

Texturing (also referred to as engraving or graining) is the procedure through which you add a pattern to the mold’s surface. Doing so will replicate the desired pattern on the plastic part you’re molding. A product’s texture drastically impacts its functional and esthetic characteristics. That’s why it’s crucial to plan it before the molding process. You need a deep understanding of the texturing process and how different patterns are added to parts. In this article, you’ll

Before you start the mold injection process, you need to consider potential modifications. Due to the subtractive nature of mold production, you can’t add material back to the mold; you can only carve it out. If you don’t get the design right, you might have to replace the molding tool altogether. Other than the above scenario, there are times when you might have to change the molding tool. Doing so can be costly and time-consuming, so you should do everything possible to av

Even though injection molding is a cost-effective mass production method, it does involve expenses that can add up over time. At some point, you might realize that your per-unit cost is higher than you’re comfortable with. This can happen for several reasons, most notably the time necessary for tooling production. The more complex the part, the longer it takes to produce, driving up the costs. Materials also play a big role as some are easier to mold than others. Fortunately

How a product looks and feels can make a world of difference to its value. That’s why choosing the right surface finish for injection molded parts is crucial. However, a surface finish goes beyond aesthetics, as it can significantly impact a product’s usability. In this article, you’ll learn about the different surface finish types and how to choose the right one. But first, we need to make an important distinction.
