Precision Weight Control Lead Weight Casting Equipment

Built for fishing tackle manufacturers that require strict weight accuracy, our 25-ton hot chamber die casting machine delivers consistent, precise lead sinker weights across every batch, reducing scrap rates and ensuring compliance with customer specifications. Optimized for lead alloy injection, it eliminates the weight variation common in lower-end casting machines.

Running at over 10 cycles per minute, this 25T machine delivers 40% higher throughput than precision-focused competitors, so you don’t have to choose between accuracy and output. Its intelligent spray system applies uniform release agent coating to every mold cavity, preventing flash and fill inconsistencies that cause weight deviations.

• Calibrated injection system delivers shot-to-shot weight consistency within tight tolerance ranges, meeting strict fishing tackle industry quality standards.
• Uniform fill quality reduces post-processing and trimming work, cutting labor costs per finished part.

An exclusive, proprietary cooler design eliminates limescale buildup entirely, allowing the machine to maintain steady die temperature even in hard water regions — a critical factor for consistent lead alloy flow and repeatable part weight.

• Integrated oil cooling system maintains steady hydraulic pressure and temperature cycle after cycle, further improving shot-to-shot weight accuracy.
• Heavy-duty, wear-resistant construction optimized for lead alloy processing supports a 10–15 year service life with standard routine maintenance.

We offer custom configuration options to match your precision lead sinker production requirements:

• Supplementary cooling unit for enhanced temperature control with high-cavity complex lead sinker die geometries
• Optional automated die spraying system for uniform, repeatable mold release across small, dense cavity layouts

We provide end-to-end support to ensure your machine maintains peak accuracy throughout its service life.

• 10-day express delivery for standard configurations, cutting lead times to get you into full production faster
• 2-hour initial response + 24-hour full resolution after-sales support for all technical issues
• 1-on-1 dedicated account manager service throughout your order and equipment service life
• On-site engineer service available for installation, precision calibration, operator training and scheduled maintenance
• Factory visits are warmly welcomed to inspect equipment and discuss your fishing tackle production needs in person
