A large diameter is preferred. This avoids localized shearing and ensures maximum pressure transfer. It is advisable to avoid sharp edges at points where the material changes flow direction, this prevents excess material sheer. Care should be taken to ensure runners are capable of cooling at least as fast as the components, keeping cycle times to a minimum. The best flow characteristics are achieved by using a full round runner, although other configurations have been used with success. Balanced flow length in the runner system will guarantee even filling of each mold cavity.
