Who We Are？
Genuine Manufacturer, Not a Trading Company
Established in 2003 and located in China's premier machinery manufacturing hub, Coolervie is a professional wire drawing die manufacturer integrating R&D, production, and global sales. For over two decades, we have focused on a single mission: engineering solutions for smoother wire drawing and maximizing die lifespan.
Our products are widely trusted in industries including electrical wire and cable, steel wire ropes, tire cords, stainless steel micro-wires, and tube drawing. Whether you require standard specifications or custom-shaped dies, our engineering team provides the optimal pass schedule design tailored to your specific drawing material.
Core Philosophy: Zero compromise on raw materials, zero shortcuts in quality inspection.
World-Class Manufacturing Capabilities
Premium Raw Materials
At Coolervie, superior dies start with superior cores. We partner with top-tier suppliers like Element Six and Sumitomo, ensuring every cylindrical PCD and ND blank delivers exceptional wear resistance and drawing stability.
Advanced Laser Drilling
We utilize imported high-precision laser drilling and wire EDM machines. This technology ensures flawlessly smooth transitions from the reduction angle to the bearing zone, entirely eliminating micro-cracks during processing.
Ultrasonic Polishing
Executed by master technicians with over 15 years of experience. Our sizing zones achieve a mirror-level finish (Ra ≤ 0.05), drastically reducing wire breakage and guaranteeing flawless output wire surfaces.
More Than a Supplier: Your Dedicated Pass Schedule Engineers
Experiencing frequent wire breaks, wire shrinkage, or premature die wear? Often, the root cause isn't the die material itself, but an unoptimized Pass Schedule.
At Coolervie, we don't just sell dies; we solve drawing bottlenecks. Our technical team provides free, customized pass schedule designs tailored to your specific material (copper, aluminum, stainless steel, tungsten, etc.), drawing speed, and area reduction rate.
We meticulously calculate the reduction ratios to guarantee the output wire diameter is perfectly and safely reduced from the input diameter. By optimizing the reduction angle and maximizing the efficiency of the cylindrical functional insert, we ensure your drawing machines run at peak performance with minimal downtime.
* Our engineers will respond with a tailored analysis within 24 hours.
