The MGS Mfg Group handles high technology molding. TecStar Mfg. Company, our custom molding division, has presses that range from 28-880 tons, over 50 multishot systems, and over 300,000 square feet of production space with multiple manufacturing facilities. We have the capabilities and capacities your  programs require.
Our engineering teams design and build automation that provides true flexibility for our customers. An automation system, properly designed and engineered, increases product quality, lowers manufacturing cycle times, and minimizes costs.
Cost-effective manufacturing is dependent upon properly maintained tooling systems. At TecStar, our preventive maintenance tool shop is staffed by over a dozen journeyman toolmakers - all dedicated to maximizing your ROI by keeping your molds productive.

3 Shot Medical Valve (In Mold Assembly Technology)
Using mechanical design techniques, moving parts can be achieved with multishot injection molding. The valve shown above has a polypropylene petcock (red) molded into a static polycarbonate housing (white). The petcock can rotate inside the housing 360 degrees by incorporating the use of a mechanical bond (bonded together by design and the use of dissimilar materials). The third shot material (blue) uses chemical bonding (bonded by the natural characteristics of similar materials) creating a soft rubber seal. This valve leaves the mold fully assembled exactly as shown because all three materials are introduced during the same molding cycle.
