Scientific Molding - Establishing a Robust Injection Molding Process

Scientific molding is taking the plastic's point of view to form identical parts consistently. A scientific approach is taken to establish all molding variables. Many traditional opinions are held invalid unless substantiated with data. We start by understanding the four critical components of any successful plastic's application:

1. Piece Part Design
2. Material Selection and Handling
3. Tool Design and Construction
4. Processing

Each is equally important! Each must be done correctly. At the heart of Scientific Molding is the scientific ability to detect in which area a problems lie and document the problems with data, not personal opinions. From the beginning of any new project each component is represented and the hard compromises made early. This keeps the program on track and on time with fewer revisions in the prototype or production stages. In each area decisions are made that affect the other three, often a compromise must be made. Industry history shows that today if compromises are made in part or tool design, or the choice of plastic, often it is the molder that lives with the problem and has to compensate for it. Scientific molding holds each component accountable: true concurrent engineering. No person is expert in all areas. All designs and decisions are professionally reviewed in the early stages of a project.

For processing we emphasize the concept that a molder’s profit hinges on the proper use of time. From inventory, to part quoting, to running jobs at or below quoted cycle time, no exceptions. All cavities running all the time. The time basis for comparison to others is 24 hours a day, 365 days a year. Time is the common denominator for all molders foreign and domestic, you must be internationally competitive. Molders see the major trends in the industry of thin walls, complex parts and multi-cavity molds narrowing their processing window. Therefore, concurrent engineering and process control becomes critical. Process monitoring...
