Some specific ways to avoid costly mistakes during the product design process are to plan for uniform wall thickness whenever possible, and to gradually transition from one thickness to another when changes in thickness are not avoidable. It is also important to avoid building stress into the design, such as corners that are 90 degrees or less. (Read more about Injection Molding Defects here.)

Design is one of the most important facets of the production
process because it’s the earliest opportunity to prevent expensive
mistakes later on. (Of course, determining whether you have a good
idea in the first place is also important, but more on that here.)
There are many objectives to design for: function, aesthetics,
manufacturability, assembly, etc. The right design is one that
accomplishes the required objectives to a satisfactory level, but
it may take a lot of creativity to get there. Product design is
most often accomplished with computer aided design (CAD) software,
like SolidWorks. (Click here for nine pro tips on how to best use
SolidWorks in design and engineering.) Proficiency with CAD
software is vital because it allows for quicker iterations and more
accurate prototyping if necessary.
Servo Machines Features
1. High energy savings
Under normal operating conditions, compared with conventional
hydraulic injection molding machines, energy savings of 20-80%
can be achieved.
2. Molding stability
Compared with conventional injection molding machines repeatability
is greatly improved due to servo motor closed-loop control.
3. Quick response
Featuring a dynamic servo motor with a response time of only
0.05sec
4. Quiet operation
The machine runs at much lower noise levels, particularly in low
speed applications.
5. Reliable holding pressure
Compared with traditional hydraulic machine the holding pressure is
more stable and does not have limitation.
