• Complex Challenges and Innovative Thinking
If you think something can't be done or can't be done better - think again. Our engineering staff provides up-front design review and assistance, reviews material selections, and plans a quality strategy. When you receive a quote from Engineered Plastics, you will know your part can be manufactured efficiently and correctly. We provide you with options and continually work to make your parts better.

We believe in making parts right the first time, every time. Our engineers use mold simulation software to optimize product design and manufacturability and proactively detect potential molding problems during the design phase. We are ISO 9001-2000 Certified and use AIAG's PPAP process to be sure our processes are consistent and will produce parts to your specifications.
• Our Focus and Experience
We love a challenge. Our extensive experience enables us to mold parts that require close tolerance multi-directional core pulls or unscrewing cores without post-mold machining. We use a custom heat staking process developed in-house to ensure more accurate placement of threaded brass inserts that exceed pullout force requirements.

We apply the same proactive, technological approach to liquid silicone rubber molding. By providing our customers with better up-front designs, we are able to ensure consistently high quality parts and reduced cycle times. In addition, we can combine our plastics and rubber capabilities, reducing labor and assembly for customers by using a two-shot molding process in-house.

We depend on everyone from our machine operators, to our engineers, our technicians, and Customer Service to work together so great things will happen.
