As a trusted manufacturer since 1998, Anping County Boli Hardware Wiremesh Products Factory is proud to present our Copper Water Bar for Injection Mold Cooling Channels, designed with a 12mm diameter and 3000mm length, along with fully customizable ends. With over two decades of experience in metal fabrication and an annual export value of US$5-10 million, we deliver precision-engineered cooling components that enhance the efficiency and longevity of your injection molds. This copper water bar is the ideal solution for maintaining consistent mold temperature, reducing cycle times, and improving part quality.
Our copper water bars are crafted from high-purity copper, offering excellent thermal conductivity to rapidly dissipate heat from mold cores. The 12mm diameter fits standard cooling channel sizes, while the 3000mm length can be cut to your exact requirements. The ends are fully customizable—options include threading, flat ends, chamfered edges, or specific fittings to match your mold design. This flexibility ensures a seamless integration into your existing cooling system without the need for additional adapters.
Key Features & Technical Specifications
- High Thermal Conductivity: Copper (≥99.9% purity) rapidly transfers heat away from the mold, minimizing hot spots and warpage.
- Precision Diameter: 12mm ±0.1mm tolerance ensures a snug fit in standard cooling channels.
- Extended Length: 3000mm standard length reduces the need for joints, simplifying installation and improving flow efficiency.
- Customizable Ends: Threaded (NPT, BSP, or metric), flat, radiused, or with O-ring grooves—available upon request.
- Smooth Surface Finish: Free of burrs and oxidation, promoting laminar water flow and reducing pressure drop.
- Rust & Corrosion Resistant: Copper naturally resists corrosion from treated water, ensuring long service life.

The benefits of using our copper water bar are clear: improved cooling uniformity leads to faster cycle times, lower scrap rates, and extended mold life. By replacing traditional steel or brass baffles with copper, you achieve up to 40% better heat transfer efficiency. This is particularly critical for complex molds with deep cavities or tight tolerances. Our bars are manufactured using advanced CNC machining and quality control processes, ensuring each piece meets strict dimensional and performance standards.
We understand that every mold is unique, which is why we offer custom end configurations without minimum order quantity. Whether you need a simple flat end for a press-fit application or a threaded end with a specific pitch, our engineering team can accommodate your requirements. Lead times are typically 7-15 days depending on complexity, and we ship globally from ports like Tianjin, Qingdao, Shanghai, and Foshan.
Frequently Asked Questions
-
Q: What purity of copper do you use?
We use electrolytic tough pitch copper (≥99.9% Cu) with conductivity of at least 100% IACS, ensuring maximum heat transfer. -
Q: Can I get a different length besides 3000mm?
Yes, we can cut to any length from 100mm to 6000mm. Please specify your requirement when ordering. -
Q: What end options are available?
Common options include: plain flat, chamfered, male/female NPT or BSP threads, metric threads, O-ring grooves, and custom profiles. Send us your drawing for a quote. -
Q: What is the typical lead time for custom orders?
For standard lengths and ends, 7-10 days. For complex custom ends, 10-15 days. Rush orders may be possible. -
Q: How do you package the bars for export?
Each bar is individually wrapped in protective foam and secured in a wooden crate to prevent bending or scratching during transit. -
Q: Can these bars be used for other cooling applications?
Yes, they are also suitable for general heat exchanger cores, cooling plates, and other thermal management systems where high conductivity is needed. -
Q: Do you offer samples for testing?
Yes, we can provide small samples (e.g., 200mm length) with simple ends. Contact us for sample pricing and availability. -
Q: What is the tolerance on the length?
Standard length tolerance is ±2mm. For tighter tolerances, please specify.
