Bimetallic screw and barrel for injection molding machine applies to LCP, PA46, PA6T, PPS, PC (with 50% glass fiber/magnetic powder), halogen-free plastic, bakelite and other engineering plastics.

The characteristics of JCD bimetallic screw and barrel are high wear resistance (HRC 60°-70°), high temperature resistance, strong corrosion resistance and stable processing performance. The dual-layer structure (SACM645 base + 3-5mm tungsten carbide lining) ensures 3-5x longer service life than standard nitrided screws. When processing high-fiber materials, it reduces scrap rate by 15% and improves production stability by 40%, with core performance comparable to international brands like Nordson Xaloy at 40% lower cost.

Our company, Dongguan Jingchuangda Machinery, is ISO 9001 & CE certified, focusing on high-performance bimetallic screw and barrel assemblies. We have served customers in automotive parts (e.g., BYD) and electronic components (e.g., Huawei suppliers), providing customized solutions for Haitian/Zhenxiong injection molding machines.

Q: What advantages does the JCD bimetallic construction offer?

A: The SACM645 base + 3-5mm tungsten carbide alloy lining (ST-A/B/C grade optional) enhances wear resistance by 3x vs. standard screws, ensuring stable operation for high-filler/abrasive materials. It meets T/ZZB 1351—2019 "Zhejiang Manufacturing" standards and passed CMA/CNAS laboratory tests.

Q: Is it compatible with my injection molding machine?

A: Yes, it’s customizable for horizontal/vertical injection molding machines (e.g., Haitian, Zhenxiong), with screw diameter ranging from Φ14mm to Φ360mm and full compatibility with engineering plastics.

Q: What’s the customization lead time and warranty?

A: 7-day rapid prototyping, 15-day mass delivery; we offer 2-12 months warranty (based on material type) and 24-hour technical response. Defects within warranty will be repaired or replaced for free.

Q: How to maintain optimal performance?

A: Regular cleaning after use and periodic inspections of the alloy layer are recommended to extend service life; our technical team provides professional maintenance guidance.

The JCD Series bimetallic screw and barrel adopts precision processing technology (72h quenching + 168h vacuum nitriding) to ensure linearity of 0.015mm/1000mm. It effectively solves the pain points of material sticking, uneven melting and short service life in high-demand injection molding. With joint design capability and stable supply, it has become the preferred choice for engineering plastic processing enterprises.
