Benefits

Parts made by the use of a Valve Gate usually have the least frozen-in stress, without any sprue, and no visible defects. Valve Gates can yield consistent shot-to-shot repeatability, faster cycle times, good automatic mold operation and better part quality. Valve Gated molds are therefore, ideal for automated high volume production.

MDi also designs and builds Valve Gate Stack systems, thus doubling capacity without a need to increase the size/tonnage of your press.

We also offer Single-Cavity Valve Gate systems with only one drop for production or prototype applications. MDi’s Single-Cavity Valve Gates feature the same gating technology used in our multi-cavity Hot Runners.

MDi offers high quality, high performance systems that are durable, dependable, competitively priced and feature MDi’s innovative nozzle and manifold technology.
