Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – your trusted partner for custom injection molded components. Since our establishment in 2017, we have been committed to delivering high-precision plastic parts for demanding applications. Our OEM Robot Vacuum Roller Injection product is specifically engineered for robotic vacuum cleaners, using premium NAK80 mold steel to achieve exceptional wear resistance and surface finish. Certified under IATF 16949, this roller meets automotive-grade quality standards, ensuring consistent performance in every cleaning cycle. Whether you need a direct replacement or a customized design, our team is ready to support your project from concept to mass production.
Key Features & Technical Specifications
The robot vacuum roller is a critical component that influences suction efficiency, noise level, and brush replacement frequency. Our injection molding process, combined with NAK80 steel tooling, delivers the following advantages:
- Superior Material Durability: NAK80 mold steel offers excellent hardness (HRC 38–42) and corrosion resistance, extending mold life and reducing part defects.
- High-Precision Molding: Using advanced injection molding machines, we achieve tight tolerances (≦±0.02 mm) and consistent part geometry.
- Enhanced Surface Finish: The polished NAK80 cavity produces a smooth roller surface (Ra 0.4–0.8 μm) that reduces friction and noise during operation.
- IATF 16949 Quality System: Our manufacturing process is audited and certified to the automotive industry’s strict quality standard, ensuring traceability and defect prevention.
- OEM Customization: We offer full design support – from material selection (ABS, PP, TPU, POM, etc.) to dimensional modifications – to match your specific robot model and performance requirements.
- Fast Turnaround & Scalable Production: With 51–100 skilled employees and a factory spanning 1,000–3,000 sqm, we can handle both prototype runs and high-volume orders (10k–1M+ units per month).

Frequently Asked Questions
Q1: What material is used for the roller itself?
A: The roller can be molded from various engineering plastics such as ABS, PP, POM, TPU, or nylon (PA66). The final material is selected based on your hardness, flexibility, and durability requirements. We can also add anti-static or UV-resistant additives.
Q2: Can you customize the roller design for my specific robot vacuum model?
A: Absolutely. We offer full OEM customization. Just provide your original sample, 3D CAD file, or dimensional drawing. Our team performs DFM analysis and offers suggestions for moldability and cost reduction.
Q3: What is the minimum order quantity (MOQ)?
A: For new projects with customized tooling, the MOQ is typically 1,000–5,000 pieces. For existing molds or standard designs, we can accommodate as low as 500 pieces. Please discuss your volume with our sales team.
Q4: How long does it take to get the first sample?
A: Lead time for mold fabrication is around 25–35 days, depending on complexity. Once mold is ready, first samples can be shipped within 5–7 business days. Expedited services are available for urgent orders.
Q5: Is IATF 16949 certification mandatory for robot vacuum parts?
A: While not mandatory for all vacuum applications, IATF 16949 certification ensures a robust quality management system, consistent process control, and traceability – all of which reduce defects and improve reliability in your end product.
Q6: How do you ensure the roller is free from burrs or flash?
A: Our molds are built with precision venting and cooling channels. In-mold sensors and post-molding automated vision inspection help detect any flash. If required, we can add secondary deflashing or ultrasonic cleaning.
Q7: What shipping options do you offer?
A: We ship via sea (FCL/LCL), air freight, or express (DHL, FedEx, UPS). The best option depends on your order weight and urgency. Our logistics team will recommend the most cost-effective method.
Q8: Can I get a sample before placing a mass production order?
A: Yes, samples are available after mold completion. We offer free samples for standard designs you approve; for custom designs, a small sample fee applies (deducted from your first production order). Contact us to discuss.
