Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. As a professional manufacturer established in 2017, we specialize in high-precision injection molds for robotic components. Our OEM Robot Vacuum Roller Mold is crafted from premium NAK80 steel, featuring a 4-cavity design capable of achieving 300,000 shots with consistent quality. This mold is engineered to produce durable and precise vacuum rollers that are essential for modern robot cleaning devices, ensuring smooth operation and long service life. With our factory spanning 1,000-3,000 square meters and a skilled team of 51-100 employees, we deliver reliable tooling solutions for global markets.
This mold is manufactured using NAK80 steel, a pre-hardened mold steel known for its excellent polishability, high wear resistance, and dimensional stability. The 4-cavity layout maximizes production efficiency while maintaining tight tolerances, making it ideal for high-volume manufacturing. Key features include:
- Material: NAK80 steel – superior hardness (approx. 40 HRC) and corrosion resistance for long-lasting performance.
- Cavity Count: 4 cavities – balanced runner system for uniform filling and reduced cycle time.
- Shot Life: Guaranteed 300,000 shots under normal operating conditions, with proper maintenance extending lifespan.
- Precision: Tolerances as low as ±0.01mm for critical dimensions, ensuring roller geometry meets OEM specifications.
- Cooling System: Optimized cooling channels minimize warpage and reduce cycle time by up to 20%.
- Surface Finish: Mirror polish (SPI A-1 grade) available for smooth roller surface, reducing friction and noise.
- Mold Base: Standard or customized to fit your injection molding machine (e.g., HRS, LKM).
- Maintenance: Easy disassembly design for quick cleaning and replacement of wear parts.
Technical Specifications (Typical)
| Parameter | Value |
| Mold Steel | NAK80 (Pre-hardened) |
| Number of Cavities | 4 |
| Shot Life Expectancy | 300,000 shots |
| Max Part Weight per Cavity | 50g (approx.) |
| Plastic Material Suitable | PP, ABS, PA, TPE, etc. |
| Mold Base Size (Typical) | 300mm x 300mm (customizable) |
| Injection Machine Tonnage | 80-150 tons |
Benefits for Your Production: This mold provides exceptional cost efficiency due to the 4-cavity design, reducing per-part tooling cost. The NAK80 steel allows for higher injection speeds and pressures, resulting in faster cycle times and improved surface finish. Additionally, the robust construction ensures reduced downtime for maintenance. Customers who have adopted this mold report a 15-20% reduction in cycle time compared to standard molds, and the 300K shot life offers long-term reliability for mass production. We also offer customization options such as hot runner systems, core pulling, and multi-component molding to meet specific roller designs.

Frequently Asked Questions (FAQ)
Q1: What materials can be used with this mold?
A1: The mold is designed to process common thermoplastics such as PP, ABS, PA (nylon), and TPE. Material selection depends on the roller's required hardness and flexibility. We can adjust gate design and cooling for specific materials upon request.
Q2: Can the mold be used on my existing injection molding machine?
A2: Yes, the mold base dimensions and gate location can be customized to fit most injection machines (80-150 tons). Please provide your machine specifications (platen size, tie bar distance, etc.) for a perfect fit.
Q3: What is the warranty period for this mold?
A3: We offer a standard 1-year warranty against manufacturing defects. Proper maintenance and usage according to our guidelines are required. Extended warranty options are available upon negotiation.
Q4: How long does it take to produce the mold?
A4: Typical lead time is 25-35 business days after design approval. Rush orders may be possible depending on current production load.
Q5: Can I get samples before mass production?
A5: Yes, we support T0 (first trial) samples for approval. Usually we ship 20-50 pieces for dimensional and functional testing. Sample fees apply and are deductible from mass production order.
Q6: What surface finish options are available for the roller mold?
A6: Standard finish is SPI C-1 (medium polish) for general applications. For smoother rollers requiring low friction, we offer SPI A-1 (mirror finish) or textured finishes like MT-11000. Cost and lead time vary.
Q7: How do you ensure the 300,000 shot life?
A7: We use NAK80 steel with uniform hardness (38-42 HRC) and design robust cooling to avoid thermal stress. Regular preventive maintenance (lubrication, cleaning) is recommended to maximize lifespan. Our previous projects have achieved 350,000+ shots under good conditions.
Q8: Do you provide mold design service if I only have a part drawing?
A8: Absolutely. Our engineering team can design the complete mold based on your 3D part file (STEP/IGS) or 2D drawing. We offer DFM (Design for Manufacturing) analysis to optimize part quality and cycle time.
