Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. – a professional injection mold manufacturer established in 2017 with a 1,000-3,000 sqm factory and 51-100 skilled employees. Our custom robot vacuum roller injection molds are engineered to deliver precision, durability, and efficiency. Using premium PC+ABS resin and NAK80 steel, combined with a 4-cavity design, this mold ensures high output rates and extended service life, making it an ideal solution for vacuum cleaner OEMs and aftermarket parts suppliers.
With our TS16969-certified quality management system and experience serving markets across North America, South America, Europe, Asia, and beyond, we offer reliable tooling that meets stringent international standards. This mold is specifically designed to produce the rotating roller brush component of robot vacuum cleaners, balancing wear resistance and surface finish for optimal cleaning performance.
Product Features & Technical Specifications
- Premium Material Combination: The mold core and cavity are crafted from NAK80 steel – a pre-hardened, mirror-finished grade with excellent corrosion resistance and polishability, ensuring long tool life and consistent part quality.
- 4-Cavity Layout: Allows simultaneous production of four rollers per cycle, boosting productivity by up to 400% compared to single-cavity molds. Ideal for medium-to-high volume orders.
- PC+ABS Part Material: The roller itself can be molded using PC/ABS blend (or other thermoplastics per your requirement), providing outstanding impact strength, heat resistance, and dimensional stability for daily vacuum operation.
- Customizable Cooling System: Conformal cooling channels can be designed to minimize cycle time and reduce warpage, leading to more uniform part shrinkage.
- Precision Fit & Finish: Tolerances held within ±0.02 mm; surface roughness Ra ≤0.4 µm for a smooth roller surface that picks up debris effectively.
- Easy Maintenance: Modular design with interchangeable inserts allows quick replacement of worn components, reducing downtime.

This mold is suitable for injection molding machines with clamping force of 200-350 tons. We also offer hot runner or cold runner options, as well as customized ejection systems (e.g., stripper plate, core pulling) depending on the roller’s undercut features.
Why Choose Our Custom Robot Vacuum Roller Mold?
- High Output & Low Unit Cost: The 4-cavity configuration reduces per-part cost, making it economical for mass production.
- Durable & Low Maintenance: NAK80 steel’s excellent polishing and corrosion resistance means fewer repairs and longer mold life (500,000+ shots typical).
- Precision Molding: Our experienced team uses advanced CAD/CAM and CNC machining to ensure each cavity is identical, eliminating imbalance issues.
- Full Customization: We can adjust cavity count, part material, surface texture (e.g., MT11000), and even integrate brush-bristle insert molding if required.
- Global Shipping: We ship from Jiangsu, Shanghai, or Shenzhen ports, offering fast delivery to all major markets.

Frequently Asked Questions
-
Q: What is the typical lead time for this custom mold?
A: Standard lead time is 30-45 days after design approval and deposit. Rush orders can be discussed based on current capacity. -
Q: Can the mold be used for other materials besides PC+ABS?
A: Yes, the mold is designed with a universal steel core and cavity that can run other thermoplastics like PP, PA, or ABS. However, we recommend confirming the material’s shrinkage rate to ensure part dimensions are correct. -
Q: Do you offer mold tryout and sample parts?
A: Absolutely. We conduct trial runs on our own injection machines and provide up to 50 free samples for your approval before shipment. -
Q: Is the mold compatible with any injection molding machine?
A: The mold base and locating ring are customizable to fit your machine’s specifications (e.g., nozzle diameter, clamping holes). Please provide your machine details when ordering. -
Q: How do you ensure the 4 cavities are balanced?
A: We use flow simulation software (Moldflow) to design balanced runner systems and validate through testing. Each cavity’s fill time and pressure are controlled to within 5% variation. -
Q: What kind of warranty do you provide?
A: We offer a 12-month warranty against manufacturing defects in materials and workmanship. Wear parts (e.g., ejector pins) are not covered but can be replaced easily. -
Q: Do you have a minimum order quantity (MOQ)?
A: For custom molds, MOQ is 1 piece. However, for mass production of parts using this mold, we require a minimum order of 10,000 pieces per run to optimize efficiency. -
Q: Can you help with part design or modification?
A: Yes, our engineering team can review your roller design and suggest improvements for moldability, such as draft angles, wall thickness uniformity, and gating locations.
