Cold Rolling Cassettes Type D
Sky Bluer manufactures the CRM-D Cold Rolling Cassettes, also known as cassette roller dies, for advanced applications in the metal processing industry. The CRM-D cassettes cold-draw a wide range of materials, including steel wire, steel rod, copper wire, flux-cored welding wire, stainless steel wire, carbon steel, titanium wire, titanium alloys, tantalum wire, and zinc wire. They actively produce wires with special-shaped cross-sections, process metals that are difficult to deform.
Types of Rolling Cassettes Installed on Drawing Machines
If you’re looking for a reliable rolling cassette to install on your existing wire drawing machine, we’ve got you covered! Contact us for comprehensive, one-stop solutions designed to meet all your factory’s production needs.

Straight Line Multi-Pass Wire Drawing Machine – The most commonly used type, suitable for continuous drawing and high-volume production.

Closed-Loop (Continuous Ring) Wire Drawing Machine – Ideal for fine wires and precision drawing, maintaining consistent wire tension.

Micro or Precision Wire Drawing Machine – Designed for ultra-fine wires or special alloy wires, using micro rolling cassettes for high-accuracy processing.
ROLLING CASSETTE
The Rolling Cassette is a highly versatile tool designed for precision wire processing. It is widely used for reinforcing wire production, rope compaction, the forming of shaped wires, forming of round wires, and the pre-calibration of wire rods before further processing. By applying stable rolling pressure and accurate shaping, the cassette ensures consistent product dimensions, improved surface quality, and enhanced mechanical performance of the finished wire. Its robust design allows it to handle both standard and difficult-to-deform metals, making it an essential component in applications that demand durability, accuracy, and efficiency in modern wire manufacturing.


MICRO ROLLING CASSETTES
Micro Rolling Cassettes are specially engineered to replace traditional drawing dies on our multi-pass drawing lines. By utilizing precision rollers instead of fixed dies, they significantly reduce friction, improve wire surface quality, and extend tool life. These cassettes ensure consistent wire dimensions, higher drawing speeds, and lower energy consumption, making them an ideal choice for modern high-efficiency wire production.
Applications About The Rolling Cassettes
Rolling cassettes from Sky Bluer, under the CRM brand, are essential tools for efficient and precise wire production. They are widely used to produce reinforcing wires with consistent strength, compact ropes and PC strands for enhanced durability, form shaped wires with specialized cross-sections for automotive, electronics, and engineering applications, and pre-calibrate wire rods to ensure uniform diameter and excellent surface finish. By choosing a trusted supplier, companies can achieve high-quality results while optimizing cost and price efficiency in their wire processing operations.
Frequently Asked Questioins
Micro Rolling Cassettes replace drawing dies in thin wire production. They are suitable for rolling any steel grade as well as for producing FCW Flux Cored Wire. Cold Rolling and Micro Rolling Cassettes are equipped with hard metal rolls.
To install a cold rolling cassette on a straight line wire drawing machine, first shut down and clean the machine. Check the cassette model and roller condition, then mount it securely in the holder, aligning the wire entry and exit. Connect lubrication or cooling lines if required. Feed wire through the cassette, adjust roller pressure, and test at low speed to ensure smooth operation. Regularly monitor lubrication, temperature, and roller wear for stable performance and long service life.
Rolling cassettes handle a wide range of materials, including steel wire, stainless steel, copper, carbon steel, titanium, zinc, and flux-cored welding wire. As a leading manufacturer, we design our CRM-D series cassettes to process both standard wires and hard-to-deform metals, making them highly versatile across multiple industries. The roller sizes range from 50 mm to 350 mm, accommodating diverse production needs.
Roller service life depends on wire type, roller material grades, reduction passes, drawing speed, and maintenance. Our CRM team design the High-quality CRM-D cassettes in China can last significantly longer than traditional dies, reducing replacement costs and production downtime. Regular lubrication and periodic inspection help maximize durability and performance.
Rolling cassettes use precision rollers instead of fixed dies, which lowers friction, improves wire surface quality, and enables higher drawing speeds. This reduces energy consumption and tool wear, lowering the overall cost of production while maintaining consistent wire quality. Choosing a reliable manufacturer or supplier like us in China ensures both efficiency and cost-effectiveness. Our technical team will assist you in calculating the cost. Please provide your production and material requirements, and we will offer two price comparisons: one using a cassette roller die and the other using a traditional wire drawing die
No, they are different. Rolling cassettes for round wire are designed with circular or curved grooves to shape the metal into a cylindrical form, while cassettes for square wire have square or rectangular grooves to produce precise angles and dimensions. Square wire rolling requires more complex design because the material tends to concentrate stress at the corners, whereas round wire flows more evenly. Using the correct cassette for each shape ensures optimal product quality, accurate dimensions, and surface finish
