Facilities List

Rolling
Heyco Metals utilizes three rolling mills to cover customer orders both large and small.

One Sundwiger Eisenhuette split-housing 20-hi reversing rolling mill with air wiping, automatic shape measurement and control, automatic contactless gage control and filtration to 1 micron absolute. This mill received a major upgrade in 2006.

Two Sendzimir solid-housing 20-hi rolling mills with automatic contactless gage control and mineral oil coolant with filtration to 1 micron absolute.

Bell Annealing
Heyco Metals uses a two-base, single stack Ebner installation with cracked ammonia atmosphere (N2/H2).

Strand Annealing
Heyco Metals operates two Drever horizontal twin-stand furnaces and five Drever single stand vertical units. All strand annealers use nitrogen/hydrogen atmospheres for the ultimate in clean, bright, oil-free surfaces on both annealed and tempered materials.

Stretch Bend Leveling
A wide-width Ungerer unit, with automatic shape measurement and control via feedback loops, provides the ultimate in flat, stress-free product. In-line surface inspection automatically scans 100% of both surfaces, capturing all specified defects for later containment, as appropriate.

A narrow width as-slit leveling unit allows us to process slit product for the best in straightness and freedom from die-exit twist etc.

Slitting
Heyco Metals use three slitters:
A wide-width Ruesch unit using loop-in/loop-out tensionless slitting for optimal slit edge characteristics. Bridle tensioning avoids friction pads and associated surface impairments. This slitter was designed to meet the stringent surface requirements of the leadframe industry. Shimless Tooling, computer generated setups and heads designed for off-line tooling changes all contribute to minimal setup time losses.

An intermediate width Ruesch unit also uses tensionless slitting via in/out loops and computer-generated shimless tooling.

A heavy gauge Yoder unit slits thicker jobs at finish, and preslits incoming reroll for optimum yields.

Traverse Winding
Heyco's three-head units efficiently wind, three strips at a time, pancake coils that have been slit at a separate operation. Heyco has two such units. They are ideally designed for small and intermediate sized jobs and avoid the complexity and long setup times associated with combined slit/wind units.
