Ultra Precision Straightener DHL-100–400 for 0.1–0.6 mm Strip | Yiming, Dongguan, China

Yiming's Ultra Precision Straightener (TUS series, models DHL-100 to DHL-400) levels thin metal strip before it enters a high-speed stamping line. It handles material 0.1–0.6 mm thick in widths from 100 mm to 400 mm.

It is designed for thin stainless steel, copper, iron and aluminium. Both the upper and lower rollers are driven through universal joints and gears, so the strip is not scratched by rollers that turn only by friction, and the machine takes up little floor space.

Key Features

• Straightening wheels made from imported SUJ2 steel, heat treated to HRC60, hard chromium plated and ground for an even coating and consistent cylindricity on every shaft
• Floating four-point balance fine adjustment with a dial indicator for quick levelling set-up
• Optional auxiliary support wheels inside the machine stop the correction rollers bending under pressure, improving roller life and sheet flatness
• Upper and lower rollers driven by universal joints and gears, avoiding power loss and surface scratching
• Frequency converter speed control, adjustable to match the feeding speed
• Compact frame with steering casters as standard, so the machine can be repositioned easily between stamping set-ups

Frequently Asked Questions

• What thickness and widths can it level? It levels strip 0.1–0.6 mm thick, in widths of 100, 150, 200, 300 or 400 mm depending on the model.
• How is the levelling speed controlled? A frequency converter sets the speed anywhere from 0 to 12 m/min, so it can be matched to the feeding speed.
• Can the machine be moved between stamping lines? Yes. It is compact and fitted with steering casters as standard, so its position can be changed easily.
• What should I send for a quotation? Send the material type, strip width and thickness, the line speed you need, the preferred sensing type (inductive rack or photoelectric), your supply voltage, and details of the stamping line it will feed.
