SAUKVILLE, Wis. (AP) -- Four of seven workers injured when a machine failed at a Saukville foundry and spilled molten metal remain hospitalized.
Police say the three others have been released from treatment. Authorities say the machine failure happened about 4 p.m. Monday at Johnson Brass & Machine Foundry. The injured workers were on a platform next to a large centrifuge that spins melted brass. The platform collapsed and molten brass was sprayed from the failed equipment, starting a small fire that was extinguished by foundry workers.
Two of the injured workers were taken by helicopter to the burn center at Columbia St. Mary's Hospital. Two additional workers were taken by ambulance to the same facility.

SAUKVILLE, Wis. (AP) -- Authorities now say that catastrophic machine failure, rather than an explosion, is to blame for injuries to seven workers at a Saukville foundry.
Saukville police Sgt. Robert Ramthun said early Tuesday that the cause of the catastrophic machine failure on Monday at the Johnson Brass & Machine Foundry is under investigation but that it wasn't criminal.
Authorities initially said an explosion apparently caused molten metal to be thrown about the room.
Ramthun says four of the seven workers were taken to the burn unit at Columbia St. Mary's hospital. The other three were also treated at hospitals.
Saukville Fire Chief Gilly Schultz said Monday that the incident happened at around 4 p.m. while workers were pouring molten brass into a cast.
