Manifold Manifolds Based on the customer molding information, the ANRY engineers can have the manifolds made to order, and meet the production requirement for carious plastic. The washer is made of special materials, it can minimize the heat loss and ensure the heat balance,better heating effect can be gained with the usage of the copper sealing technology in heater surface of manifolds. The interior of manifolds utilize the balanced runner design and have special polishing technology, this can eliminate the dead space, satisfy the demand of all kinds of injection molding. The main injecting nozzle is mounted to the manifold with screws,choose the heating or non-heating main injecting nozzle according to the type of plastic.
