The quality of plastic components is, in part, determined by the injection molding partner you choose. Properly vetting new, different or specialized vendors involves qualifying a pool of potential molders based on your project needs — i.e. ISO and other certifications, design capabilities, clean room specifications, and value-added services like assembly and overmolding. However, taking the vetting process one step further by conducting on-site quality audits will reveal which has the right level of expertise, facilities, and quality procedures in place to deliver to specific project requirements.
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 is working with the client 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, as well as any secondary finishing operations that might be required.
Medical OEMs make device reliability a top priority, working with complex injection molders that are experienced in scientific molding to ensure accuracy in processes and production. The higher level of precision helps minimize overall costs by allowing for identification and correction of problems prior to production.
Converting metal parts to plastic is becoming an increasingly standard practice in a number of industries from automotive to defense and public safety. The decision to use plastic instead of metal seems like a no brainer given the many advantages like lighter weight, lower material costs, quicker manufacturing times and extended tooling life.
While the injection molding process is a mainstay for many industries, it isn’t static. Molders are continually challenged with evolving their knowledge and use of emerging tooling technologies, materials and trends to make products that are competitively advantageous and profitable for manufacturers.
Faster time to market is a distinct competitive advantage, but making speed a priority can jeopardize injection molding process efficiencies — and your product performance.
The complexities of engineering a plastic part or product for use in a critical-use application must translate to moldability. If a molder is inexperienced in mold design and process optimization, there’s a good bet they won’t be familiar with methodologies essential for creating a highly efficient production process such as scientific molding and, more specifically Design of Experiments (DOE) within scientific molding. This article discusses key steps tool and process engineers take to ensure consistent and repeatable manufacturability of flawless molded parts.
Manufacturers of medical devices and other medical applications often turn to a complex injection molder for help correcting defects in their engineered plastic components. At Kaysun, we actively seek to prevent defects before they even occur by using a design for manufacturability (DfM) approach that incorporates a comprehensive mold flow analysis and extensive plastics engineering experience to identify any potential issues in the design phase and determine the best strategy to produce defect-free parts.
Complex injection molders entrusted with producing plastic components for medical and other critical-use applications assume a high degree of responsibility to ensure the device performs properly, without fail in sometimes life-endangering situations.
