Welcome to Changzhou Hongxinyutai Precision Mold Co., Ltd. We are a specialized manufacturer of injection molds and molding services, established in 2017 with a factory spanning 1,000-3,000 square meters and a skilled team of 51-100 employees. Our expertise lies in delivering high-precision OEM solutions, and our Injection Molding Service for OEM Vacuum Roller – 1*4 Cavities, NAK80, Textured Mold Surface, Cold Runner, IATF 16949 is a clear demonstration of our capability to meet demanding industrial requirements. This service is designed to produce durable, dimensionally stable vacuum rollers that perform consistently in your application.
The mold is engineered with 1*4 cavities to maximize productivity while maintaining tight tolerances. The use of NAK80 mold steel ensures excellent wear resistance, high polishability, and long tool life, even under high-volume production. A textured mold surface is applied to create the desired surface finish on the roller, which is critical for grip and function in vacuum systems. The cold runner system minimizes material waste and simplifies process control, making it a cost-effective and environmentally friendly choice. Our entire production process is governed by the IATF 16949 quality management system, ensuring consistent quality and traceability.
Key Features & Technical Specifications
- High-End Mold Steel (NAK80): Pre-hardened stainless steel with excellent mirror finish capability and corrosion resistance – extends mold lifespan and reduces maintenance.
- Precision 1*4 Cavity Design: Balanced filling and ejection, optimized for cycle time reduction and consistent part quality across all cavities.
- Textured Mold Surface: Custom texture depth and pattern (e.g., MT-11000) to match your specific roller surface requirements – enhances grip and release properties.
- Cold Runner System: No hot runner controller needed; simpler construction, lower initial cost, and less material degradation – ideal for engineering-grade plastics.
- IATF 16949 Certified Process: Strict adherence to automotive-grade quality standards, including PPAP, FMEA, and SPC – ensures reliability for demanding OEM applications.
- OEM Service: We accept your part drawings or samples; we provide DFM (Design for Manufacturability) feedback and full tooling design service.

Beyond specifications, this injection molding service brings tangible benefits to your business. The 1*4 cavity configuration directly boosts your output per cycle, reducing per-part cost without sacrificing accuracy. NAK80’s high hardness and corrosion resistance mean fewer mold repairs and longer intervals between maintenance, maximizing uptime. The textured surface eliminates secondary operations (like sandblasting or coating) for many rollers, saving time and expense. Cold runner technology, while traditional, offers simpler operation and lower upfront investment compared to hot runner systems, making it an economical entry point for medium-volume production.
Our company has been serving global markets including North America, South America, Eastern Europe, Southeast Asia, and more, shipping from ports in Jiangsu, Shanghai, and Shenzhen. With over 7 years of tooling and molding experience, we have honed our capabilities in handling complex geometries and high-precision components. We are confident that our Injection Molding Service for OEM Vacuum Roller, backed by IATF 16949 quality control, will meet or exceed your expectations.

Frequently Asked Questions (FAQ)
-
What is the typical lead time for a vacuum roller mold with 1*4 cavities?
Standard lead time is 25-35 working days, depending on complexity and surface texture requirements. We can expedite for urgent orders with additional rush charges. -
What plastic materials are compatible with this mold design?
The NAK80 steel and cold runner system can process most thermoplastics such as ABS, PP, PC, Nylon, POM, and their filled variants. We will recommend the optimal resin based on your roller application. -
Do you offer sample testing before mass production?
Yes, we provide trial shots (T0/T1) and adjust the mold until the parts meet your specifications. After approval, we proceed to production. -
How long will the NAK80 mold last under continuous production?
NAK80 molds typically achieve 500,000-1,000,000 cycles with proper maintenance (lubrication, periodic polishing). The textured surface may require re-application after 200,000-500,000 cycles depending on abrasion. -
Can you customize the mold surface texture pattern?
Absolutely. We support a wide range of texture finishes from standard SPI/VDI to custom-made patterns based on your sample or drawing. Please discuss your requirements with our engineering team. -
What quality reports do you provide?
We can supply CMM inspection reports, material certificates, dimensional checklists, and PPAP documentation (if required) in compliance with IATF 16949 standards. -
How do you handle mold maintenance after delivery?
We offer full after-sales support including remote troubleshooting, spare parts, and on-site service (if needed). Our team provides maintenance guidelines to maximize tool life. -
Do you accept small quantity orders for the vacuum roller?
Yes, we accommodate both prototype runs and mass production. For low volumes, we can optimize the cold runner to reduce material waste and keep costs reasonable.
