As a specialized manufacturer in precision mold solutions, Changzhou Hongxinyutai Precision Mold Co., Ltd. proudly presents our OEM IATF16949 Auto Fluid Tubing Joint Injection Automatic Unscrewing Mold designed for PA66 materials. With a dedicated factory spanning 1,000–3,000 square meters, a team of 51–100 skilled employees, and TS16969 certification since our establishment in 2017, we deliver molds that ensure consistent quality, high efficiency, and long service life. This mold is specifically engineered for producing automotive fluid tubing joints in PA66, featuring an automatic unscrewing mechanism that reduces cycle time and eliminates secondary operations.
Our automatic unscrewing mold integrates advanced hydraulics/pneumatics to precisely control core rotation, enabling seamless release of complex threaded joints. The mold cavity, core, and cooling channels are optimized using CAE analysis to guarantee uniform filling and minimal warpage. Below are the key technical specifications:
| Mold Base Standard | Custom or DME/Hasco equivalent |
| Steel Hardness | HRC 48–52 (core & cavity) |
| Unscrewing Drive | Hydraulic motor / rack & pinion |
| Max Injection Pressure | 1800 bar (depending on molding machine) |
| Cycle Time | 25–40 seconds (typical, varies with cavity count) |
| Coolant Type | Water or oil (optional) |
Key Features & Benefits:
- Automatic Unscrewing Technology: Eliminates manual unscrewing, reduces labor cost, and prevents part damage. Ideal for high-volume production.
- PA66 Compatibility: Optimized gate and runner design for Nylon 66 (with 0–50% glass fiber), ensuring excellent flow and dimensional stability.
- TS16969 Certified Facility: Manufacturing processes follow stringent automotive quality standards, including FMEA, control plans, and PPAP documentation.
- Flexible Cavity Configuration: Available in 1, 2, or 4 cavities to match your production volume requirements. Tooling design supports future cavity expansion.
- Conformal Cooling Channels: 3D-printed or machined cooling lines provide uniform temperature control, reducing cycle time by up to 20% compared to conventional designs.
- Durable Construction: Core and cavity inserts made from high‑grade tool steel (1.2343/1.2344) with nitriding/heat treatment, achieving a lifespan of over 500,000 cycles under normal conditions.
- Customizable Shuttle & Ejection: We can integrate hydraulic cylinders, limit switches, and customized ejection systems (e.g., air poppet, ejector sleeves) as per your automation setup.
Application Specifics:
This mold is designed specifically for automotive fluid tubing joints used in brake lines, fuel systems, and coolant circuits. The automatic unscrewing action accommodates both internal and external threads, making it suitable for fittings of sizes ranging from 6 mm to 18 mm (customizable upon request). Our engineers can adjust the thread pitch, draft angles, and side actions to meet your exact geometry.

Frequently Asked Questions (FAQ)
-
Q: What is the minimum order quantity (MOQ) for this mold?
A: For a custom OEM mold, MOQ is typically one set. We can produce single cavity or multi‑cavity molds based on your volume forecast. -
Q: Do you provide mold design proposals before production?
A: Yes, we provide a detailed 3D design review (with parting line, cooling, and unscrewing motion simulation) for your approval prior to steel cutting. -
Q: Can you make the mold compatible with different injection molding machines?
A: Absolutely. We adapt the mold clamping hole pattern, ejector bolt layout, and nozzle radius to match your specific machine brand (e.g., Engel, Arburg, Haitian). -
Q: How long is the lead time?
A: Typical lead time is 30–45 working days for a single‑cavity mold, depending on complexity and current workload. Rush orders may be accommodated with an expedite fee. -
Q: What PA66 grades have you worked with before?
A: We have experience with PA66+GF30, PA66+GF50, and impact‑modified grades from suppliers like DuPont, BASF, and Solvay. We can adjust processing parameters accordingly. -
Q: Do you offer mold trial and sample shipment?
A: Yes, we conduct mold trial on our own injection machines and send 10–50 pieces of injection‑molded samples for your evaluation before shipment. -
Q: What is your warranty policy?
A: We provide a 12‑month warranty (or 200,000 cycles, whichever comes first) covering workmanship and material defects. Spare parts are available at cost. -
Q: Can you design the mold for other thermoplastics besides PA66?
A: While this mold is optimized for PA66, the same unscrewing mechanism and steel selection can be adapted for POM, PBT, or PP compounds with proper gating and cooling adjustments. Please consult our engineering team.
