localized tpe overmolding on aluminum sheet

Wall thickness in the range from 0.060" to 0.120" will ensure good bonding in most overmolding applications. If the part requires the use of thick sections, they should be cored out to minimize shrinkage problems and to reduce the part weight. The use of radii (0.020" minimum) in sharp corners helps reduce localized stress.

Dec 01, 2002 · But since overmolding is usually limited to the thin skin of TPE, the softer feel is influenced by the hard substrate underneath. If a hardness test is done in this case, a lower indenture will be observed, resulting in higher hardness even though the skin may be soft.

TPE Overmolding, Bonding and Substrate Considerations. Design engineers choose TPEs for improved ergonomics, enhanced grip performance, improved aesthetics, and critical impact protection. Applications that benefit from TPE overmolds range from consumer goods to medical insruments to industrial tools and can include knobs, handles, gaskets, seals and grips.

Overmolding Design Considerations Obtaining rubber like performance with the processing ease of injection molding is the primary benefit of TPEs. Improved cycle times and reduced scrap rates result and allow for improved part economics.

Keeping radii between 0.020" or 0.5mm minimum in corners reduces localized stresses. If the part requires the use of thick TPE sections, they should be cored out to minimize shrinkage problems, reduce the part weight and lower cycle time. Avoid deep or un-ventable blind pockets or ribs in your design.

Overmolding Services. Overmolding is a process where a single part is created using two or more different materials in combination. Typically the first material, sometimes referred to as the substrate, is partially or fully covered by subsequent materials (overmold materials) during the manufacturing process.

Shore Hardness is measured using a durometer gauge, which uses a spring loaded steel rod to compress the surface of the TPE sample and provide a reading. A reading of 0 Shore describes the maximum possible indentation of the rod into the specimen, and 100 Shore indicates almost no indentation al all or a very high resistance to indentation.

The overmolding process produces chemically bonded parts made from multiple materials. Insert Molding → Insert molding is similar to overmolding, but the substrate is not necessarily plastic and does not have to be produced via injection molding. For example, insert molding can be used to add a plastic coating to a pre-fabricated metal part.

Thermoplastic elastomers can be formed into parts in the same way that other thermoplastics can be, so a "soft" TPE can be molded or extruded onto a "hard" thermoplastic in one process. This "co-molding" or "overmolding" creates design freedom that is not possible with thermoset rubbers. In addition, processing is much more efficient.

Traditionally, overmolding starts with injection molding a hard plastic resin that has a higher metling point. Then, once that part is cooled, another plastic resin (usually a soft material such as TPE, TPU or TPV) is injection molded over the first part. Sometimes called elastomeric overmolding, elastomer overmolding.

Jun 01, 2008 · Olefinic TPEs originally comprised only two classes of rubber-modified polypropylene, known as TPO and TPV. More recently, these have been supplemented by new types of olefinic elastomers that can be used on their own or as the rubber component in TPO/TPV compounds. Additionally, a small handful of specialty TPEs using olefinic matrices occupy niche applications.

Plastic Injection Molding Service . Plastic Injection Molding is the most common manufacturing method to produce plastic parts in commercial and industrial use. In this process granular resin will be melted under high temperature and injected into the cavity of a metal tool, cooled down and formed to a solid shape based on the geometry of the tool.

Overmolding also uses fewer man-hours (and thus, costs less) compared to other manufacturing methods where a part would need to be transferred to a completely different mold or machine. Overmolding reduces the need for product assembly because parts are manufactured right on top of one another—resulting in a stronger, more durable overall design.
