A Spectrum of Molding Processes to Meet Your Design and Cost Targets
Finding the optimum process to satisfy your design and cost targets is where MFG comes on strong in delivering value.
As a composites specialist, we have the know-how and molding technologies to meet most targets. This enables us to guide you to the most efficient manufacturing approach and provide seamless transition through your project’s different lifecycle stages.

Here’s what we need to know to help you:
- Production volume over time
- Product size/shape/surface finish
- Mechanical properties
- Cost target
If you are undecided which process is best for your application, the Fast Facts Chart below can steer you in the right direction.
