  VI. PA66+GF30 Integrated Pump Head – Product Overview

  Material Selection and Characteristics

  The PA66+GF30 Integrated Pump Head is manufactured using polyamide 66 reinforced with 30% glass fiber – a high-performance engineering thermoplastic widely adopted in automotive thermal management modules, electric vehicle water pumps, and industrial fluid systems.

   

  Key material attributes:

   

  High strength and rigidity – Glass fiber reinforcement significantly increases tensile and flexural strength

   

  Heat resistance – Continuous use temperature of 120–150°C; short-term tolerance up to 250°C

   

  Dimensional stability – Glass fiber reduces shrinkage and minimizes deformation risk

   

  Chemical resistance – Heat-stabilized and glycol-resistant for permanent contact with water/coolants

   

  Fatigue resistance – 2.5× higher than unreinforced PA66

   

  Material challenges addressed by Ansix Tech:

   

  Challenge Ansix Solution

  High mold wear (glass fiber abrasion) Premium wear-resistant steels (H13, S136, 420 stainless) + surface treatments

  Reduced melt fluidity Optimized gate design, elevated melt temperatures (280–300°C)

  Mold corrosion (PA66 acidity) Corrosion-resistant steel grades + protective coatings

  Fiber orientation-induced warpage Multi-point gating, zone-controlled mold temperatures

  Material Drying and Preparation

  PA66+GF30 requires rigorous drying before processing due to its inherent hygroscopic nature (吸水率 up to 2.5%):

   

  Drying temperature: 80–100°C (not exceeding 110°C to prevent agglomeration)

   

  Drying time: 4–6 hours (vacuum drying can reduce to 3 hours)

   

  Target moisture content: ≤ 0.2% using desiccant dryers with dew point ≤ -40°C

   

  Alternative: 100–120°C for 2–4 hours in forced-air ovens

   

  Customer Value: Proper drying prevents bubbles, silver streaks, and degraded mechanical properties—ensuring pump heads that are structurally sound and visually defect-free.

   

  VII. Manufacturing Process – From Mold Design to Delivery

  1. Mold Flow Analysis and DFM

  Before any steel is cut, Ansix Tech conducts comprehensive mold flow analysis using advanced simulation software:

   

  Predicts weld line and air trap locations

   

  Optimizes gate count and placement

   

  Balances cavity filling

   

  Validates cooling channel effectiveness

   

  Customer Value: Digital validation replaces costly physical trial-and-error. Problems are solved in simulation, not on the production floor.

   

  2. Mold Design and Manufacturing

  Design priorities for PA66+GF30 pump head molds:

   

  Cooling system: Conformal cooling channels (3D-printed or CNC-machined) that follow cavity contours, improving cooling efficiency by over 40%

   

  Runner and gate design: Sharp corners avoided to reduce glass fiber erosion; multi-gate configurations minimize warpage

   

  Ejection system: Enhanced ejector pin count or hydraulic ejection to handle high demolding forces of PA66+GF30

   

  Venting: Exhaust slots (0.02–0.03mm depth) at melt flow endpoints to prevent air traps

   

  Mold steel selection for PA66+GF30:

   

  For abrasive, glass-fiber-reinforced materials in high-volume production, Ansix Tech selects high-quality, corrosion-resistant steels such as H13 or 420 stainless steel. Heat treatment to HRC 52+ reduces wear, with optional surface treatments (chrome plating, nitriding) for extended life.

   

  Mold manufacturing process:

   

  Steel selection and procurement (with material certifications)

   

  Rough machining (CNC)

   

  Heat treatment

   

  Precision machining (5-axis, EDM, wire EDM)

   

  Surface finishing and polishing

   

  Assembly and fitting

   

  Trial molding and validation

   

  Customer Value: Each step is documented and traceable. Customers receive a mold that is engineered specifically for their pump head geometry and production volume requirements.

   

  3. Injection Molding Process Optimization

  Critical process parameters for PA66+GF30:

   

  Parameter Recommended Range Impact on Quality

  Barrel temperature – rear 270–290°C Prevents premature melting, maintains fiber distribution

  Barrel temperature – middle 280–300°C Ensures homogeneous melt, fiber-matrix bonding

  Barrel temperature – front 285–305°C Optimizes flow, prevents premature cooling

  Nozzle temperature 280–300°C Prevents drool and stringing

  Injection pressure 80–150 MPa Ensures complete cavity fill with GF-reduced fluidity

  Holding pressure 40–90 MPa Compensates for shrinkage

  Mold temperature 80–120°C Balances crystallinity and shrinkage

  Cooling time 15–40 seconds Balances cycle efficiency vs. warp risk

  Back pressure 5–15 bar Ensures homogeneous plasticization, gas evacuation

  Process optimization strategies:

   

  Multi-stage injection: Speed and pressure分段 controlled – fast fill followed by slow holding

   

  Zone-controlled mold temperatures: Different temperatures for core and cavity to manage differential shrinkage

   

  Closed-loop process control: In-cavity sensors provide real-time feedback for automatic parameter adjustment

   

  Customer Value: Optimized parameters mean shorter cycle times, lower energy consumption, and consistent part quality. Ansix's process expertise reduces per-part cost while maintaining quality.
