Since 1985, Expert has been using various types of liquid silicone materials, two-part cure material, one-part cure material, and RTV. He also has extensive experience with different injection molding machines and developed injection molding processes associated with coining, venting, and breathing method. He successfully implemented these processes to manufacturing with zero failures. All development were based on the “Scientific Molding Process Development” principle.

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.

Expert may consult nationally and internationally, and is also local to the following cities: Los Angeles, California - Long Beach, California - Santa Ana, California - Anaheim, California - Riverside, California - Bakersfield, California - Glendale, California - Huntington Beach, California - Oxnard, California - Garden Grove, California
