 The Dielectric Tape Caster has been designed specifically for the manufacture of dielectric ceramic tape used in multi-layer ceramic capacitors (MLCC) and piezoelectric sensors. This Carsten model provides a relatively low volume of continuous tape, well suited for the production of MLCC's. It also finds wide acceptance as a small, continuous caster for prototype manufacturing of larger volume, thicker tape applications, as well as R&D on new slurry formulations. This production model comes in two standard sizes:
• 10 Inch Wide by 20 Foot Long - Two Infrared Drying Zones
• 10 Inch Wide by 28 Foot Long - Three Infrared Drying Zones
The endless belt is a welded, polished carbon steel belt driven by a controlled frequency motor for precision adjustment of the casting speed. Custom-designed belt widths and lengths are available for specific applications. Units come equipped with a precision micrometer doctor blade assembly to adjust the tape thickness, independent drying zone controls, razor stripper, and paper roll take-up assembly for dried tape.
 Harrop offers a variety of custom-designed Carsten tape casting systems to meet the specific production needs for mass production of tape in a number of emerging technology industries. These larger units have standard nominal belt widths of 12 inches, 24 inches, and 31.5 inches, and are designed with lengths from 30 feet up to 100 feet. Belts are typically stainless steel and can be equipped with a carrier film system on which to transport the tape through the caster. Any number of independently controlled drying zones can be provided to insure proper curing of the "green" tape. Both aqueous and non-aqueous binder exhaust systems can be provided. Precision controls of tape thickness, belt speed, and zone temperature are standard design features. Optional features can include:
• Slurry Level Control
• Granite Casting Surface
• Continuous Tape Thickness Monitoring
• Dancing Arm Take-Off System
• Tape Slitter

 The Carsten line of continuous ovens offers a variety of designs for low-temperature heat treating of "green" ceramic tape and parts. For applications including ink drying, epoxy curing, glass sealing, and solder fusion, infrared conveyor ovens are often indicated. These Carsten Infrared Ovens are designed with either Teflon/fiberglass or stainless steel transport belts, depending on the temperature requirements. Nominal belt widths are 8 inches and 12 inches, and come in oven lengths up to 6 feet long. Controlled infrared heating and binder exhaust systems are standard.
For continuous binder removal from tape cast, pressed or extruded ceramic parts, the Carsten Burn-Out Oven is an attractive alternative to batch ovens. Product is carried on an endless stainless steel belt through multiple electrically heated zones with stainless steel internal surfaces. Forced-air recirculation systems with individual zone temperature control assure safe, uniform binder removal. Two standard models are offered:
• 3-Zone - 18 Inch Wide Belt by 9 Foot Heated Length
• 6-Zone - 36 Inch Wide Belt by 13 Foot Heated Length
Temperature capability up to 450°C is available. All units include a 4 foot entrance loading station and a 4 foot exit unloading station. |
