    How Shrink Rate Dictates Injection Molding Outcomes and Part Quality

    Not taking the time to properly determine shrink rate can have a big impact on the quality of an injection molded part's geometry, performance, and appearance. 

    To facilitate this calculation, materials suppliers typically provide shrink rate numbers based on ASTM Standard D955 and a .125-inch thick plaque with a specific gating size and location. Although a good place to start, this value is usually not accurate enough for many products, especially critical, highly complex parts.

    How Injection Molders Can Help Define And Maintain Quality Standards

    Quality is an important benchmark in all aspects of an injection molding project, and rightfully so. Producing high-quality plastic parts is always the goal, but how often do you stop to consider what a supplier misstep, a materials snafu or a process miscalculation could do to a project overall? Poor quality — in any form and to any degree — can have far-reaching impact. The solution is partnering with an experienced injection molder that can help you keep quality at the forefront in every aspect of a project:

    How Design for Manufacturability (DfM) Factors Into Project Success

    Almost any reasonable design looks good on paper or even as a prototype, but that doesn’t mean it’s a sure thing when it comes to manufacturing it. On the other hand, using Design for Manufacturability (DfM) to improve part design, injection molding processes and material selection ensures a product or component can be manufactured in a streamlined, efficient, validated, and repeatable way — saving time and money.

    Is Your Injection Molder Capable of Medical Device Traceability?

    Not surprisingly, the medical industry in the United States is one of the most heavily regulated. The U.S. Food & Drug Administration (FDA) has a strict protocol around medical device tracking, particularly Class II and Class III devices that are intended for life support away from a primary care facility or whose failure would likely cause serious adverse health consequences.

    How Engineering Support Optimizes Complex Injection Molding Projects

    Moving an idea from conception through production can take many paths. However, what initially appears to be the "easy route" can sometimes lead to complications, including certain efficiencies being overlooked or lost. Generally, spending more time and effort up front can simplify the process and provide desired outcomes, especially when you enlist the engineering expertise of your injection molding partner.

    How to Objectively Determine the Stability of Your Injection Molder

    For all practical purposes, supply chains are extensions of an OEM’s capabilities and services. Injection molders on an OEM’s approved supplier list must demonstrate certain core competencies that help address — and alleviate — OEM concerns around quality, cost, reliability and a host of other factors that could influence outcomes and, ultimately, their reputation and bottom line.

    How Specialty Tool Materials Help Speed Cooling Times

    Cooling is one of the most critical parts of the injection molding process. Not only is it the longest part of the process — taking up more than 80 percent of the cycle time — but it's not smart to cut corners when it comes to cooling. In order to achieve precise, tight tolerances, the cooling rate must be carefully controlled — not rushed to completion.
