When it comes to remaining competitive in the global marketplace, speed matters. Manufacturers want injection molded parts that deliver the most product functionality at the lowest cost — and they want the parts quickly to get to market first and fastest.
Injection molders understand the pressure manufacturers are under. They're also attuned to how injection molding design, engineering, and production expertise can greatly speed up development time.
Geometric dimensioning and tolerancing (GD&T) is a symbolic language that is used on engineering drawings and computer-generated models. It communicates geometric dimensions and allowable tolerances for various parts. Not only is this a useful exercise for product design, it’s also helpful on the manufacturing floor because engineers and operators can quickly see the degree of tolerance that is required for each part.
Federal Corporate Average Fuel Economy (CAFE) Standards coupled with heightened consumer sensitivities to the environmental impact of using fossil fuels are tightening fuel consumption requirements for the auto industry.
Polymer science has made tremendous strides over the years, rapidly advancing the ability to compound a variety of resins with fillers and reinforcements that provide a vast amount of structural and chemical integrity.
Surface finish on plastic composites can vary a great deal, depending on the physical and chemical properties of the polymer blend as well as the parameters of the injection molding process.
The first objective for a custom injection molder is working with the customer to determine how important the surface finish is for the appearance and/or performance of the final product. For example, does the product need to be eye-catching or simply functional? Depending on the answer, the material selected and the desired finish will determine the settings for the injection molding process, and any required secondary finishing operations.
Overmolding is a value-added injection molding method for improving plastic and metal substrate performance and aesthetics. While seemingly simple, the process has a number of underlying complexities that must be carefully considered to ensure your overmolding project meets all goals and expectations.
Injection-molded and blow-molded plastic parts are so pervasive in everyday life that the two processes are sometimes thought of as interchangeable. While the two may be used in an individual application — perhaps a blow-molded fluid reservoir is attached to a custom injection-molded medical device — injection molding and blow molding serve different purposes and markets.
An increased speed to market is a distinct competitive advantage, but making speed your first priority can jeopardize injection molding process efficiencies — and product performance.
Accelerating speed to market and upholding quality doesn’t need to be an "either or" proposition. Early in the design phase, seek out an injection molding partner that thinks and delivers beyond the standard injection molding process. If your ultimate goals include preventing costly rework, and eliminating defects and unanticipated product failure, look for an injection molder with expertise in mold filling analysis, scientific molding, and other time and cost saving process methodologies.
There are several prototype tooling options for your designs — the one you choose really depends on what you expect to accomplish with the prototype. For example, will the prototype be subjected to testing? Does it need to be "dressed up" for presentation? Will it need to meet tight tolerance requirements?
The most common prototyping options are SLA/SLS, urethane cast, soft tooling, and hard tooling. But which is right for your component? Read on to discover the advantages and disadvantages of each.
