Knowing Your Flow Ratio. Company. In the case of nylon, for example, if you are processing 30% glass-filled compound with a moisture content of 0.17%, (established with a moisture-specific method—weight loss is not acceptable), you may feel you are ready to process. Glass-filled nylons need larger diameter runners and thicker part walls by as much as 50 percent more than unfilled nylon parts. The glass fibers do increase strength, but they also impact the way a part fails.
READ MORE . Complex Injection Molding ± 0.005″ tolerance, waterproof up to 25ft, molded-in vertical ribs for tool-free assembly. The key is to understand a resin’s limitations and how they might affect your project. When it comes to plastic injection molding, no material is perfect. For glass-filled nylon, these challenges include: It is more brittle than standard nylon Injection Molded ABS – Nylon ± 0.002″ close tolerance, internal port requires slide in tool, part assembly 33% glass filled Nylon. We provide this exact service and have vast experience in glass filled nylon. Depending on the percentage of fill, glass fibers can significantly improve the strength and rigidity of parts versus corresponding unfilled resins, but with strength comes brittleness. With injection molding, Nylon is sometimes filled with a certain percentage of glass fibers to increase its tensile strength. The hooks we are injection molding are actually above 40%. Chinese Injection Mold Making Companies Development Trends Many Chinese injection mold making companies has also made significant progress in the CAE application, and achieved good results. Home; Who We Are; About Us; CAD File Transfer; … The most common form of maufacturing these components is glass filled nylon injection moulding.
I typically will use these materials when cavity details are too small or intricate to add water lines. Request a Quote. Glass fibers are the most commonly used additives in plastic injection molding at Protolabs. Nylon as a material is very strong and heat resistant – therefore this makes it an ideal material of choice for a wide variety of products and components. Disadvantages of Using Glass-Filled Nylon in Small Plastic Parts. Glass filled nylon wore down these plastic injection mold in 8 months, we had to retool. READ MORE. But you’re not.

When used to mold glass-filled materials, these alloys should be coated to prevent erosion, which is an extra cost (along with added maintenance). The 0.20% moisture specification is for the nylon only, not the glass. The percentage of glass is typically between 10% and 40%. READ MORE. With no glass fill, Nylon will bend and yield before it breaks. A design book published several years ago by Monsanto (now Dow Solutia) contained a flow ratio chart. Fill out my online form.
