There isn’t a whole lot that injection molders can do to speed up how long it takes to receive hard tooling. While they wait, however, they can take a number of key steps to streamline the product development process, up to and following the completion of the actual injection mold—saving up to a week or longer in lead time.
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.
Each new injection molding project has three inherent goals: performance for the customer; production efficiency for the manufacturer; and reliability for the end user. These goals are reasonable. The challenge lies in accomplishing all three within a desired timeframe and budget. To do so, plastics engineers at complex injection molders turn to Design of Experiments (DOE) to identify flaws that would otherwise derail project success.
Defect-free, low-cost critical use injection molded parts are the intended result of any project. But, how do you get from start to finish and remain on time, on spec and on budget?
Critical-use medical device manufacturers are faced with keeping pace with technological advancements and earning market share while simultaneously producing extremely precise and reliable medical products. Meeting all these challenges is a tall order, and utilizing the scientific molding process can help.
Much has been said about the ability of scientific molding to provide optimal control of the injection molding process – and in turn – help manufacturers of critical use-devices that contain precision-molded parts keep pace with competition and be the first to market. But what some wonder is what really makes scientific molding work in the first place. And the answer is the engineers who specialize in it.
When performed by molding personnel with thorough training and the proper certification, scientific molding virtually guarantees top quality by removing all guesswork from the injection molding process. The aim is to develop templates for repeatable production.
