Changzhou Hongxinyutai Precision Mold Co., Ltd., established in 2017, is a specialized manufacturer located in Changzhou, Jiangsu, China. With a factory spanning 1,000–3,000 square meters and a dedicated team of 51–100 skilled employees, we focus on delivering high-quality precision molds for global clients. Our Industrial High Pressure Fluid Pump Actuator Housing Insert Mold is engineered to meet the demanding requirements of automotive and hydraulic systems, featuring S136 steel with mirror-polished cavity for superior surface finish and dimensional accuracy. This mold is designed to support efficient mass production of actuator housings, reducing cycle time and enhancing part consistency. Backed by IATF16949 quality management standards, our mold ensures reliability and long-term performance even under high-pressure operating conditions.
Our insert mold is specifically crafted for high pressure fluid pump actuator housings, which are critical components in modern hydraulic systems. The mold uses premium S136 stainless steel (equivalent to 4Cr13) that offers excellent corrosion resistance, wear resistance, and dimensional stability. The cavity undergoes a rigorous mirror polishing process to achieve a surface roughness below Ra0.05μm, ensuring that each actuator housing has a smooth, defect-free interior that minimizes friction and fluid leakage. This mold is ideal for producing parts with complex internal geometries and strict tolerances required in automotive braking systems, steering pumps, and industrial hydraulic actuators.
Key Features & Technical Specifications
- Material: S136 (AISI 420 modified) – through-hardened to 48-52 HRC for extended mold life and reduced maintenance.
- Cavity Finish: Mirror polished (Ra ≤ 0.05 μm) – eliminates surface defects, improves part release, and reduces post-machining operations.
- Insert Design: Modular insert construction allows quick changeovers and cost-effective repairs; core and cavity inserts are replaceable individually.
- Cooling System: Optimized conformal cooling channels ensure uniform heat dissipation, reducing cycle time by 15-20% compared to conventional designs.
- Ejection System: Hydraulic or mechanical ejection options available; designed to handle delicate actuator housing ribs without distortion.
- Precision Tolerance: ±0.01 mm on critical dimensions, verified by CMM inspection reports supplied with each mold.
- Compliance: Designed and manufactured under IATF16949 quality system, with full traceability and FMEA documentation.
- Customization: Gate type, runner layout, and venting can be tailored to specific resin (e.g., PPS, PA66+GF30) and part geometry.
| Parameter | Specification |
|---|---|
| Mold Base Material | P20 / 1.2311 (standard) or S50C (optional) |
| Cavity / Core Steel | S136 (1.2083) – ESR grade |
| Hardness | 48–52 HRC |
| Surface Roughness | Ra ≤ 0.05 μm (mirror) |
| Max Mold Size | 600 x 600 x 500 mm (customizable) |
| Cycle Time (est.) | 25–40 seconds (depending on part geometry) |
| Cavity Count | 1+1 (standard) or multi-cavity available upon request |
Advantages over conventional molds: The mirror polish on the S136 cavity dramatically reduces friction between the plastic melt and the mold surface, enabling faster filling and lower injection pressure. This results in actuator housings with superior mechanical properties and dimensional stability. Additionally, the insert design simplifies maintenance – if a cavity is damaged, only the insert needs replacement, saving time and cost. Our molds have been tested in high-volume production environments, consistently achieving over 1,000,000 cycles before requiring minor refurbishment.
Applications & Market
These molds are primarily used for manufacturing actuator housings in high pressure fluid pumps found in automotive power steering systems, brake boosters, transmission oil pumps, and industrial hydraulic units. The actuator housing must withstand pressures up to 200 bar and operate reliably in extreme temperatures (-40°C to 150°C). Our mold design ensures that the final part meets the required sealing and fatigue resistance. We have successfully supplied molds to clients in North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East, including a special project for Saudi Arabia where local environmental conditions (high temperature, sand) demand additional robustness.
Trust & Reliability
As a manufacturer with 6+ years of experience (since 2017) and a dedicated facility of 1,000–3,000 square meters, we have built a reputation for precision and on-time delivery. Our 51–100 employees include senior mold designers, CNC operators, and quality inspectors who work under the IATF16949 quality system (product certification TS16969). We use advanced equipment such as high-speed CNC, EDM, and CMM to ensure every mold meets the strictest standards. We offer full after-sales support, including mold trial, optimization suggestions, and spare parts supply. Our shipping ports (Jiangsu, Shanghai, Shenzhen) provide convenient logistics to global destinations.
When you choose our Industrial High Pressure Fluid Pump Actuator Housing Insert Mold, you benefit from a partner who understands the critical nature of fluid power components. We invite you to discuss your specific requirements – we can customize the mold to suit your injection molding machine, resin, and production volume.

Frequently Asked Questions
-
Q: What is the minimum order quantity for this mold?
A: We accept single mold orders. For first-time clients, we recommend starting with one mold for validation before bulk orders. -
Q: Can the mold be used for materials other than standard resins?
A: Yes, the mold design can be adapted for engineering plastics like PPS, PA66+GF30, PEEK, and LCP. We will adjust gating and cooling to suit the material. -
Q: What is the typical lead time?
A: For a standard single-cavity insert mold, lead time is approximately 30–45 working days, depending on complexity and current workload. We can expedite for urgent projects. -
Q: Do you provide mold trial and sample parts?
A: Absolutely. We offer free mold trial at our facility, and we can ship sample parts for your evaluation before final payment. -
Q: Is the mold guaranteed against defects?
A: Yes, we provide a 12-month warranty against manufacturing defects (excluding wear from normal use). We also offer lifetime technical support. -
Q: How do you ensure the cavity mirror finish is consistent across multiple cavities?
A: Our polishing process uses automated polishing machines followed by manual inspection with interferometer. Each cavity is verified to meet Ra ≤ 0.05 μm before assembly. -
Q: Can you match an existing actuator housing design with reverse engineering?
A: Yes, we can scan a physical sample to create CAD data and manufacture the mold accordingly. Please send the sample or 3D file for evaluation. -
Q: What shipping terms do you offer?
A: We ship via sea or air from Jiangsu, Shanghai, or Shenzhen ports. Common terms are FOB, CIF, or DDP depending on your preference.
Note: IATF16949 certification is implemented in our quality management system. For specific certificate copies, please request via our sales team.
