Abstract

A cure process improves the durability of a particulate disk product through polymerization; however, this durability is greatly affected by variations in temperature and heating rate of the disk. When the number of disks is increased for a single cure oven load, it becomes increasingly difficult to guarantee minimal process variation. If the oven cannot be enlarged, then the equipment used to handle the disk must be improved. The attached cure cart design has been used successfully in disk manufacturing. It has ten locating mounts for cure racks that are specifically designed for each product size. The mounts have tapered pins that are set at an angle for each rack removal. The mounts are staggered on the cart to eliminate masking of the oven air flow.

Cure Oven Cart

A cure process improves the durability of a particulate disk product through polymerization; however, this durability is greatly affected by variations in temperature and heating rate of the disk. When the number of disks is increased for a single cure oven load, it becomes increasingly difficult to guarantee minimal process variation. If the oven cannot be enlarged, then the equipment used to handle the disk must be improved. The attached cure cart design has been used successfully in disk manufacturing. It has ten locating mounts for cure racks that are specifically designed for each product size. The mounts have tapered pins that are set at an angle for each rack removal. The mounts are staggered on the cart to eliminate masking of the oven air flow. Since the oven air flows across the cart horizontally, each disk is exposed to the same air volume. The mounts are also staggered vertically; rack mounts at the bottom of the cart are positioned farther away from the center post to reduce the risk of handling damage during rack removal.
