Mold Design with Mold Flow Analysis

Mold tool designers utilize the latest software to  take the customers CAD model directly into tool design. 
A perfect, defect-free part begins with the mold. Building the tool likely represents the largest investment in the manufacturing process; therefore, getting it right is critical to the success of a project.  Additionally, the volume of parts required, as well as the material they will be made of will help drive how and with what materials to create the mold.

Injection molding moldflow analysis

Picture

It is used to simulate the complex of injection molded polymer melts and flows through the part cavity with data collated for interpretation. It helps to predict and eliminate potential molding problems prior to cutting of steel.

By suggesting alternative design options in combination with material selection and processing conditions evaluate, assist and optimize the design for the injection molding process.

injection molding with gating at end of parts

Picture

Highly warpage and longer filling time.

Poor quality of parts and higher molding cost as shorter cycle time.

More uniform and shorter filing time.

Good quality of parts and lower injection molding cost as shorter cycle time.

Short shot and gas burned !

Gate at 6.35mm position  and found air trapped at top of part, thus causing short shot with gas burned at this region of part!

Quality injection molding part  without air trapped 

图片
After mold flow analysis, with gate at 8mm position, air venting easily  achieved on tool parting surface, this producing good quality and easily injection molding plastic part.
