Custom OEM Injection Molding Service – Robot Vacuum PC+ABS, 1*1 Cavity, Cold Runner, Glossy Surface
Product Spotlights
We are Changzhou Hongxinyutai Precision Mold Co., Ltd., a specialized manufacturer with over 7 years of experience in precision injection molding. Our Custom OEM Injection Molding Service for robot vacuum components utilizes high-quality PC+ABS material, a 1*1 cavity cold runner design, and a glossy surface finish. This service is engineered to deliver dimensional stability, aesthetic appeal, and cost-effective production for your robot vacuum housings, covers, and structural parts.
By choosing our service, you benefit from our strict quality control, experienced engineering team, and a factory covering 1,000–3,000 square meters. We ensure every mold is built to exact specifications, reducing cycle times and minimizing waste. The cold runner system combined with a single-cavity approach offers precise control over material flow, ideal for prototyping or medium-volume production.
Key Features & Technical Specifications
- Material: PC+ABS blend – offers high impact resistance, heat deflection, and excellent surface finish capability.
- Cavity Configuration: 1*1 (single cavity) – perfect for custom designs, quick mold changes, and low-to-medium volume runs.
- Runner System: Cold runner – reduces material waste, simplifies mold construction, and lowers tooling costs.
- Surface Finish: Glossy (SPI A-2 or equivalent) – provides a smooth, high-gloss appearance suitable for visible exterior parts.
- Application: Robot vacuum – designed for structural integrity, lightweight, and aesthetic requirements.

Benefits to Your Business
- Cost-Effective Prototyping: Single-cavity cold runner molds are affordable and allow quick design iterations.
- High-Quality Surface: Glossy finish eliminates secondary painting or coating for many applications, saving time and cost.
- Material Performance: PC+ABS provides excellent strength, UV stability, and flame retardancy (UL94 HB/V-2 available on request).
- Tailored Support: Our engineers work directly with you to optimize gate location, cooling, and ejection for your specific part geometry.
- Consistent Quality: Cold runner systems ensure stable melt temperature and consistent packing, reducing warpage and sink marks.

Frequently Asked Questions
-
Q: What is the minimum order quantity (MOQ) for this custom molding service?
A: Typically, we accept orders starting from 500–1,000 pieces for injection molding, but lower quantities can be discussed for prototype runs. Please contact us for your specific needs. -
Q: Can you match a specific glossy finish standard (e.g., SPI A-2)?
A: Yes, we can achieve a range of glossy finishes from SPI A-1 to A-3 based on mold texturing and polishing. We will confirm with your sample or standard. -
Q: Do you provide material certificates for PC+ABS?
A: Yes, we can supply material test reports (MTR) and certificates of compliance for the materials we use, such as UL or RoHS declarations upon request. -
Q: How do you ensure dimensional accuracy for the single-cavity mold?
A: We use precision machining (CNC, wire EDM) and conduct in-process inspections with CMM equipment. Final parts are measured before shipping. -
Q: What file formats do you accept for mold design?
A: We accept STEP, IGES, STL, and native CAD formats (SolidWorks, UG, ProE). Our engineers can also work with 2D drawings. -
Q: Is the cold runner design suitable for high-volume production?
A: While cold runner molds are efficient for medium volumes (up to 100,000 cycles), for very high volumes we recommend hot runner systems. We can advise based on your project scale. -
Q: Can you add branding or logos as part of the molding process?
A: Yes, logos or text can be engraved into the mold cavity to produce permanent markings on the part surface. This is a standard service. -
Q: What is the typical lead time for mold fabrication and first samples?
A: Mold fabrication generally takes 20–35 days, and first samples (T1) are delivered within 5–7 days after mold completion. Urgent requests can be prioritized.
