Abstract
This relates to a hot runner manifold for distributing thermoplastic melts from a plasticizer to plural cavities of a mold. The manifold is formed in two parts which include a plate and a ring which are joined along a central parting line in a manner wherein all of the sprue and runner portions may be readily and accurately machined. The ring is shrunk in place on the plate and has an interference fit which is sufficient to prevent separation of the ring from the plate during normal operating conditions without the use of any fasteners.
