At Changzhou Hongxinyutai Precision Mold Co., Ltd., we specialize in delivering high-precision injection molds tailored for demanding applications. Our 1×1 Cavity PC+ABS Injection Mold for Robot Vacuum is engineered to produce durable, glossy exterior parts for robotic vacuum cleaners. With a hardened S136 steel core and cold runner design, this mold ensures consistent quality across up to 300,000 shots, making it an ideal choice for manufacturers seeking reliability and long-term value.
This mold is crafted using PC+ABS (Polycarbonate/Acrylonitrile Butadiene Styrene) blend material, which offers excellent impact resistance, heat deflection, and surface aesthetics. The cold runner system minimizes material waste and simplifies maintenance, while the hardened S136 steel (48–52 HRC) provides superior wear resistance and corrosion protection. The glossy surface finish (SPI A1 grade) meets the high visual standards of consumer electronics, giving your robot vacuum a premium look. Our mold is compatible with standard injection molding machines and can be customized with additional features such as side cores, lifters, or gas venting upon request.
As a TS16969-certified manufacturer (ISO/TS 16949 equivalent, certified since 2017), we adhere to strict quality controls. Our facility spans 1,000–3,000 square meters and houses 51–100 skilled employees, ensuring each mold passes rigorous inspection. We have exported to markets including North America, Europe, Southeast Asia, and Africa, providing consistent on-time delivery from Jiangsu, Shanghai, or Shenzhen ports.
Key Features & Specifications
- Cavity & Core: Single cavity, suitable for medium-volume production of robot vacuum housings.
- Mold Steel: Hardened S136 (DIN 1.2083) – high polishability, corrosion resistance, and toughness.
- Runner System: Cold runner with two-plate design; easily adjustable for drop feed or submarine gates.
- Shot Life: Rated for 300,000 injection cycles under standard PC+ABS processing conditions.
- Surface Finish: Glossy (SPI A1) – mirror-like finish achieved through precise polishing and chrome plating.
- Cooling System: Optimized baffle or cascade cooling lines to reduce cycle time and prevent warpage.
- Ejection: Standard ejector pins with optional hydraulic or pneumatic cylinder assist.
- Injection Press Compatibility: Suitable for 100–300 ton clamping force machines (customizable).

Frequently Asked Questions
-
Can this mold be used for other materials besides PC+ABS?
Yes, with minor gate adjustments, the mold can process PP, ABS, or PC/PBT blends. However, the surface finish and shrinkage should be verified via simulation. -
What is the minimum order quantity (MOQ)?
We accept single mold orders. Production MOQ for parts depends on the client’s needs; we can provide sample runs of 100–500 pieces. -
Do you provide mold design service?
Yes, our engineering team can design the mold based on your 3D part file. We also offer DFM report and moldflow analysis at no extra charge for confirmed orders. -
How long is the warranty?
We offer a 12-month warranty against material defects and workmanship from the date of shipment. Normal wear of ejector pins and guide components is excluded. -
Can you modify the mold to increase shot life beyond 300K?
Yes, upgrading to H13 tool steel or high-alloy materials (e.g., S136H) with additional heat treatment can extend life to 500K+ shots. Please discuss with our sales team. -
What about spare parts availability?
We keep standard spare parts (ejector pins, springs, o-rings) in stock. Custom parts can be manufactured within one week. -
Do you test the mold before shipping?
Absolutely. Every mold undergoes a trial run at our facility. We provide a trial report and video evidence upon request. -
How do you ensure the glossy surface on deep cavities?
We use polishing techniques combined with hard chrome plating on cavity surfaces. For complex geometries, we recommend adjusting the injection pressure and mold temperature to achieve uniform gloss.
