  • Patent number: 6558159
    Abstract: A container (10) for holding parts during a heat treating process. The container includes a bottom plate (14), end walls (20 and 22), sidewalls (30 and 32) and dividers (40, 42 and 44) which are connected together using a tab and slot construction to form an egg crate structure. The construction of the container reduces the effects of the heat treating process on the container. The guide cradle (58) in the compartment (12) of the container supports the cylinder head in the compartment and reduces the movement of the cylinder head during the heat treating process. The positioners (60) on the top portion (58A) of the guide cradle guides the cylinder head into the guide cradle and into the compartment. The bottom portion (58B) of the guide cradle supports the cylinder head above the bottom plate.
