2-in-1 Uncoiler Straightener for Unlimited Coil I.D. Light Stamping Lines
Henli CL Series combines coil uncoiling and straightening in one compact, caster-mounted machine. Its dual-plate clamping design removes the inner diameter restriction found on mandrel decoilers, making it a practical solution for small I.D. coils, light strip, and narrow material.
- For small or non-standard coil I.D.: dual-plate clamping supports coils that standard expansion drums cannot hold.
- For economic automation: pairs with air feeders, mechanical roller feeders, or NC servo feeders to build an entry-level stamping line.
- For flexible workshops: compact vertical body and heavy-duty casters make the unit easy to move between press stations.
Economic Uncoiling and Straightening for Small Coil I.D. Applications
The CL Series is a specialized decoiler straightener combo for light, thin, and narrow metal strips where surface requirements are standard and the production goal is practical, low-cost automation.
One-Stop Starter Unit for Light Press Lines
Unlike traditional heavy-duty decoilers, this simplified unit combines coil support, uncoiling, and leveling in one machine. It is especially useful for small-batch production, dedicated molds, and factories moving from manual feeding to automated press feeding.
The machine can work with air feeders, mechanical roller feeders, or NC servo feeders depending on speed, precision, and budget.
Five Practical Reasons Buyers Choose the CL Series
The page now groups the original selling points into a compact technical board: coil I.D. flexibility, compact footprint, mobility, roller durability, and easy adjustment.
Designed for small coils and flexible workshop layouts.
The CL Series is not a heavy-duty mandrel decoiler. Its value is solving small I.D. coil loading, portable layout, and economic automation in one compact unit.
1. Unlimited Coil Inner Diameter
Dual-plate clamping avoids strict mandrel I.D. limits, making the machine suitable for special small I.D. coils and non-standard coil packaging.
2. Compact Space-Saving Footprint
The vertical integrated structure reduces floor occupation and helps smaller workshops keep aisle space clear around press stations.
3. High Mobility with Casters
Four heavy-duty casters allow operators to relocate the machine for different presses, useful for job shops and flexible production cells.
4. Hardened Straightening Rollers
40CR chrome steel rollers with hard chrome plating and HRC60 surface hardness improve wear resistance for long-term daily operation.
5. Simple 4-Point Micro-Adjustment
Handwheel adjustment and reference scales make leveling setup practical for operators who need fast changeover and repeatable settings.
Best Fit
Light, thin, and narrow metal strip with standard surface requirements and a need for economic automated press feeding.

Machine Structure and Production Reference
The original detailed images are retained and placed where buyers can understand machine structure, rollers, controls, and production readiness.
What Buyers Can Verify from the Details
The detail image set shows the compact body, coil clamping area, straightening rollers, adjustment handles, and control area. This supports practical inspection before quotation instead of relying only on generic product photos.
The batch production image also confirms the machine is a repeat production model, not a one-off custom unit.
Four Common Stamping Line Configurations
The CL Series is most useful as the first machine in a light-duty automated line. Choose the downstream feeder according to budget, speed, and feed length flexibility.
Economic Starter Line
Pair CL Series with an air feeder for simple stamping parts, lower budget projects, and dedicated molds where easy maintenance matters most.
High-Speed Mechanical Line
Use a mechanical roller feeder for high-volume fixed-pitch stamping that needs stable mechanical synchronization.
Precision Flexible Line
Pair with an NC servo feeder when feed length changes often or the line needs programmable control for job-shop production.
Modern Silent Workshop
Compact CL machines can be positioned around soundproof stamping booths, helping keep high-end workshops organized while feeding material efficiently.
Coil reel and strip straightener for thin, light and narrow metal coil
Search terms such as coil reel straightener, 2-in-1 uncoiler straightener and thin-metal-coil leveler describe the CL/CL-A route when its dual-plate coil support and live capacity table match the job.
Coil support and material
The dual-plate arrangement does not depend on a mandrel expansion range. Confirm coil O.D., weight, width, thickness, material strength and the practical plate/stack geometry before selecting CL-150 through CL-400.
CL or PUL for thin strip?
CL is an economical route for light and narrow strip. If the enquiry adds high-precision flatness, delicate surfaces, stainless steel, copper or very thin stock, compare the PUL precision series and define an acceptance method.
Power press line pairing
The CL body combines uncoiling and straightening. A complete automatic stamping line normally adds a separate air, roller or NC servo feeder according to feed pitch, speed and press interface.
Custom configuration and quotation
Send material, coil and press data for a comparable quotation. HENLI manufactures CL and CL-A configurations for the verified coil and line requirement; generic price, discount or wholesale labels do not replace model selection.
