SFM is used to produce a wide variety of components and parts. Below are some examples of structural foam production parts and the benefits they offered. Structural foam creates a cellular core and solid outer skin during molding, making it an ideal method for large, thick parts. High-pressure foam molding eliminates sink marks and gives you a 90% better surface finish and in most cases, the surface is ready to paint or finish with little or no sanding. A steel tool may be required if the resin of choice is a glass filled material or an aggressive abrasive material. Not consenting or withdrawing consent, may adversely affect certain features and functions. Click in the table below for specific material, Low cost tooling with the same molded-in detail and features possible in standard injection molding. The resulting product has a tough, dense exterior skin and a lighter core. A Lomont product that is molded using the structural foam process will typically have a surface which appears to have swirls on it. Multiple colors can also be applied to a single part in-mold. Various materials and/or colors can be molded together Structural Foam Molding is a low-pressure foam injection molding process where molten resin is injected with nitrogen gas or a chemical blowing agent. Structural foam is just one method of plastic injection molding that Synectic has extensive experience in developing. However, this still will not be comparable to a traditional molding finish. Previously designed as multiple component parts, it was redesigned to be made as a single structural foam part. Structural foam molding needs Nitrogen to be injected into the melt before it is injected into the mold. The end product tends to be lightweight and rigid with a relatively hard surface. Due to its not quite solid nature, the base material used in the creation of structural foam is typically a thermoplastic polymer rather than a thermoset. Instead of using high pressures to force the molten polymer to fill up the cavity of the mold, structural foam molding relies on the foaming action Of course, structural foam initially became known for its ability to create parts of unparalleled size, such as the roofs or body panels of vehicles. family.

Our High Density foam comes in 2 part kits.This kit includes the AB Foam Components. A cross-section of a structural foam molded part will show a cellular internal core sandwiched between two solid wall sections. It is also used for forming glass bottles, and blow moulding borrows its process principle from glassblowing. Superior impact resistance due to the honeycomb core structure All Structural Foam products are 100% recyclable. Structural foam production uses a low-pressure injection molding process. Thus weight and resin savings may not hold true when compared to the same part molded traditionally. As a result, you can use foam molding to make lightweight, durable forms of almost any type of conventional plastic. Email: [email protected], Cookie Policy | Privacy Policy | Terms of Use Policy. This low-cost molding process produces parts that are structurally sound, nearly stress-free and have minimal warpage. Can mold medium wall thickness through very thick wall sections with minimal sink marks. It is used to process thermoplastics, such as high density polyethylene (HDPE), in a low pressure environment. The structure of the material is like that of a sandwich, with the low density core completely surrounded by the higher density skin. This yields parts that are much larger and sturdier than injection molded parts. Each phase of manufacturing - custom resin production, injection molding, secondary operations, finishing, assembly, and Kan Ban kit packing and shipping - strictly follow rigorous quality controls and procedures, and are continuously monitored and documented from start to completion. The molten resin is injected into a mold after being mixed with a low percentage of foaming or blowing agent. Fax: +1 (732) 851-7771 This process allows for less volume of plastic than a solid injection molded part to completely fill the mold, or . structural foam molding. However, there is one important difference necessary for the creation of structural foam rather than a solid polymer. Structural foam is a low-pressure form of injection molding, which utilizes most thermoplastics, (including post-consumer regrind), to mold rigid products, which can have thicker walls and higher stiffness-to-weight ratios than standard injection molded products. Additionally, the molding pressure decreases due to the presence of expanding gas. Two different materials and or two different colors can be run at the same time. Faster cycle times The lower pressure and forces involved allow more economical molding equipment and tooling to be utilized compared to other molding methods. Compare to plastic molds and die casting, Structural foam molding is total different type of mold. This low pressure also allows for far less expensive tooling because long-lasting molds can be made of aluminum, rather than tool steel. Therefore, parts are likely to have thicker wall sections. The process creates a singular large and complex part that normally requires many components to complete. What is structural foam molding? For a more detailed overview, please go to https://www.tranpak.com/tools/faq/what-is-struc. This process yields part weight reduction, sink elimination, and lower molded-in stress. Our production facilities are awarded with specific certifications of compliance to global standards. However, it soon became apparent that structural foam promised a number of additional benefits. Injection pressures are much lower than straight injection molding, as the mold front fills the cavity of the mold the gas expands and packs out the cavity. The complex geometric detail and size of these assemblies often turn into molded parts that cannot be made without structural foam. Two components, for example polyol and isocyanate (which are combined in order to create polyurethane) are stored in liquid form in separate containers. Contact Supplier Request a quote. Structural Foam MoldingStructural Foam Injection MoldingGas Counter-Pressure Injection MoldingGas Assist Injection MoldingStraight Injection MoldingFinishing. It expands, filling the empty space of the mold with foam. In plastics manufacturing, dimensional stability is the measurement of how well a plastic maintains its size during shifts in temperature and humidity. The finished surfaces of a structural foam part are inherently rough from the foam texture. With in-house design and processing expertise Mack can support our customers foamed part opportunities, ensuring they are on a path to utilize the benefits of this process.

It also means proudly manufacturing our products in America, and making them available to the global marketplace. Oftentimes, the structural foam molded parts are strong enough to be used in place of fiberglass or even metal parts. Gas present within the plastic decreases plastic weight and lowers resin costs. Structural foam materials are created through the combination of a base resin and a foaming agent, such as nitrogen gas, or a chemical blowing agent. In addition, structural foam produces no potentially harmful styrene fumes, lowering the health risks for workers involved in the molding process. Another useful element of the gas bubbles molded inside foamed parts can be the inherent thermal insulation and sound deadening qualities. Structural foam products have a lower than average risk of damage in the mold or during the removal process, making it a highly efficient and easily repeatable method. In the molding process, foam concentrates are added to thermoplastics -from the simplest to the most advanced engineering materials depending on your needs. The final part after being redesigned as a structural foam piece. Get Quote. More recently, blow moulding has been demonstrated with amorphous metals also known as bulk metallic glasses (BMGs) under . Injection of foaming polymer into mold. The molding process utilizes low-pressure to mold the parts which results in low stress and warpage in the parts. Designing parts for manufacturingusing structural foam requires a few more considerations when compared to traditional plastic injection molding. This solid surface and foamed inner core reduce the part weight up to 30%.
