Silicone Molding Process Development, Silicone tooling, Silicone Sheeting, Silicone Extrusion, Silicone Dipping, and Silicone Molding Troubleshooting
ID: 735085
California, USA
Since 1985, Expert has been using various types of high-consistency (HCR) silicone materials, two-part cure material, one-part cure material, RTV, as well as using an extensive variety of compression molding machines to develop compression molding processes. He successfully implemented these processes to manufacturing with zero failure. All development were based on the “Scientific Molding Process Development” principle.
Since 1985, Expert has been using various types of liquid and high-consistency silicone materials, two-part cure material, one-part cure material, RTV, dispersion, and coatings for Dacron, Felt, and Reemay to develop coating processes. He successfully implemented these processes to manufacturing with zero failure. All development were based on the “Scientific Molding Process Development” principle.
Since 2000, based on his extensive silicone molding knowledge, Expert has been providing silicone mold tool design and conceptual ideas, and has successfully completed several mold design projects. He has also qualified various mold tooling based on client, FDA, and CFR 21 requirements.
Using his decades of experience with medical device manufacturing and silicone extrusion, Expert has successfully investigated and performed systematic root-cause analysis using the DIMAC process, and fishbone principle with 6M elements. He has resolved issues ranging from typical injection molding problems to multi-component molding processes.
Expert has been using the scientific molding process and lean manufacturing principles (one-piece flow) to reduce overall costs from development to product launch, thereby reducing the costs of the finished goods to clients. This provides for an increased margin for sales, or reduced prices to end-users.
Expert has served as a consultant to:
Edwards Lifesciences, Allergan Medical, Halyard Healthcare(Avanos Medical, Inc), Fisher and Paykel Healthcare, Zimmer Biomet, and other firms.

| MD&M Minneapolis Conference Team invited as a speaker |
| Publications and Patents Summary |
|---|
| Expert holds a patent for his Compressible Foam Wound Dressing. This gel is applied to a skin-facing surface of the foam sheet to foam skin-contacting layer. The resultant wound dressing maybe stretched and placed upon a person’s skin to overlie a wound and provide a fluid impermeable barrier between the wound and the external environment. |
