Double Injection Molding – 2K injection molding or two shot injection molding

Double Injection Molding – 2K injection molding or two shot injection molding

Double Shot injection molding which some people call 2K injection molding or two shot injection molding, is the process of molding two or more different plastic materials into one part at one time. One important element of double shot injection molding is the two materials must be compatible with each other and designed to overmold. Otherwise, the product doesn’t hold up during the procedure, sometimes overmolding is also a single type of 2k injection molding, but a lot of the materials that are designed for over molding may not be appropriate for this two-shot process. This is because one material requires a larger amount of cycle time to produce than the other material. Again, compatibility of materials is key.

Injection molding materials

Vowin provides hundreds of injection molding materials solutions, with a few proprietary materials engineered right within their facilities. Many material offerings are tied in with a specific technology due to the nature of the manufacturing processes. Below, the materials (which are often indicated by the technology they are married to) have been categorized into model/ prototype parts and functioning durable parts capable of meeting production requirements. It is best to consult with our Project Engineers if your material requires regimented standards and for further specifications.

Design Tip How to Use Multi Jet Fusion for Functional 3D-Printed Parts

Design Tip How to Use Multi Jet Fusion for Functional 3D-Printed Parts

Technology giant HP has developed and launched Multi Jet Fusion (MJF), an industrial-grade 3D printing technology that quickly and accurately produces functional prototypes and end-use parts for a variety of applications. Protolabs served as one of several test sites for this additive manufacturing process because of its experience in industrial 3D printing, and recently added HP Jet Fusion 3D 4200 printers to its suite of manufacturing tools. Here are several considerations to keep in mind when designing for MJF.

Design Tip 6 Ways to Optimize Part Design for CNC Machining

Manufacturing prototypes and production parts fast and cost-efficiently is often a balancing act of quick-turn CNC machining capabilities and an optimized part designed for those capabilities. As such, there are a handful of important considerations when designing parts for Protolabs’ milling and turning processes that can accelerate production time while reducing costs.

Design Tip Industrial 3D Printing for Production Parts

Consider this list: Fuel nozzles for General Electric’s LEAP engine; cabin brackets for Airbus A350 aircraft; patient-specific hearing aids and skull, hip, and ribcage replacements; and LED power-indicator housings for battling robots. These are just a few examples of fully functional end-use parts produced by industrial 3D printing technology, also known as additive manufacturing, shattering any lingering reputation that it’s a “prototype only” manufacturing process.

Design Tip What is Selective Laser Sintering (SLS)

Design Tip What is Selective Laser Sintering (SLS)

Sintering is the process of applying heat and/or pressure to fuse bits of metal, ceramic, and other materials into a solid mass. It’s nothing new. Nature has been fusing sedimentary minerals into slate and quartzite for eons, and humans began using similar methods to make bricks and porcelain millennia ago. Today, sintering is used to produce everything from gears and connecting rods to sprockets and bearings. It’s also used to 3D print parts.

Design Tip Turning to Lathe for Cylindrical Parts

It was once a no-brainer. Round parts were turned on lathes; non-round parts were machined on mills. With the advent of CNC machining centers, which interpolate round part features with ease, the line between the two machining processes became blurred.

Design Tip How to Design an SLA Prototype

Stereolithography, or SLA, emerged in the mid-1980s and established itself as a staple of additive manufacturing (AM) over the next decade. Since that time, SL’s ability to quickly and accurately create complex prototypes has helped transform the design world like never before.

Bridging the Gap Between Prototyping and Production

Bridging the Gap Between Prototyping and Production

In the traditional approach to product development, there is a sharp line between development and production. Development begins with a light bulb over someone’s head, proceeds through napkin sketches and CAD models, and ends, ultimately, with prototypes. At one or more points in the development process there may be input from the market, be it someone’s best guesses, one or more focus groups, or actual market tests. And from start to finish there is always pressure to “get on with it,” either because you need to catch up with a market leader or because you are the leader and someone may be catching up with you. But then, when you have reached your goal—a fully developed, marketable product—everything comes to a screeching halt and the drawings and/or models disappear into the “production machine,” from which, weeks or months later, a whole lot of deliverable product appears and the rush begins again as it heads off to market.
