This rigorous inspection protocol ensures that every mold meets specifications before leaving the factory.

   

  Customer Value: CPK ≥1.33 means the process produces virtually no out-of-spec parts—fewer rejects, less scrap, and lower total cost of ownership for the customer.

•  Mold Manufacturing Core Competitiveness: Delivering Measurable Results

  2.1 Mold Steel Selection and Hardness

  For PEEK injection molding, mold steel selection is critical due to the material's high processing temperatures and abrasive nature. PEEK and glass-fiber-reinforced PEEK present significant challenges in terms of wear, thermal expansion, sealing, venting, and dimensional stability. Ansix Tech selects mold steels based on application requirements:

   

  Mold Component Recommended Steel Grades Rationale

  Mold Base P20 Cost-effective, good machinability

  Cavity/Core (Standard) H13, 2344, 8407, SKD61 High hot hardness, thermal fatigue resistance

  Cavity/Core (Corrosive environments) S136, M340, 4Cr13, 9Cr18, STAVAX Corrosion resistance, excellent polishability

  Cavity/Core (High wear) DC53, SKD11 Superior wear resistance for glass-filled grades

  High-gloss/Transparent parts NAK80 Excellent polishability, Ra<0.05μm

  For general PEEK molding applications, H13 or S136 high-hardness stainless steel with deep tempering is recommended—not just for wear resistance, but to ensure dimensional stability under long-term high-temperature cycling. For corrosive environments or medical/food-contact applications, S136 corrosion-resistant stainless steel is prioritized. All mold steels undergo full热处理 with hardness reaching HRC55 or above to ensure cavity wear resistance. Complete material certification reports and heat treatment curves are provided to customers.

   

  Customer Value: Proper steel selection directly translates to mold life—50万 shots for glass-filled PEEK grades and 100万 shots for unfilled grades. This means fewer mold replacements, lower amortized tooling costs, and uninterrupted production schedules.

   

  2.2 Achievable Tolerances

  Ansix Tech delivers precision at multiple tolerance tiers:

   

  Standard structural components: ±0.05mm

   

  Precision gears and medical components: ±0.005mm

   

  Customer Value: Customers receive parts that fit the first time, every time. No rework, no assembly issues, no field failures due to dimensional non-conformance.

   

  2.3 Mold Types and Capabilities

  Ansix Tech manufactures a comprehensive range of mold types to meet diverse production requirements:

   

  Hot runner systems: Reduce material waste and cycle time

   

  Stack molds: Double production efficiency

   

  Two-shot/multi-material molds: Enable complex multi-material valve seal designs

   

  High-gloss molds: Surface roughness Ra<0.05μm for transparent or cosmetic applications

   

  2.4 Gate and Runner System Design

  PEEK melt has high viscosity, requiring careful runner and gate design. Ansix Tech employs full-round runners to minimize pressure loss. For gate design, side gates or large-size point gates are preferred, with gate thickness reaching at least 50%-80% of the part's thickest section to prevent premature freezing during the packing stage. Through comprehensive Moldflow analysis, the company pre-identifies weld line and gas trap locations, optimizing gate quantity and positions to ensure balanced filling.

   

  Customer Value: Optimized gate design eliminates short shots, weld lines, and voids—common failure points in valve seals that lead to leakage and field failures.

   

  2.5 Mold Delivery Standards

  Mold Complexity Standard Lead Time Expedited Lead Time

  Simple molds 10 days N/A

  Medium complexity 25-45 days 20 days (with accelerated validation)

  High complexity 45-60 days 35 days

  Customer Value: Predictable delivery timelines enable customers to plan production schedules with confidence, reducing inventory carrying costs and time-to-market.

   

  III. Injection Molding Process Control: Eliminating Quality Anxiety

  3.1 Process Standardization and Parameter Lockdown

  All injection molding machines are networked and connected to a MES (Manufacturing Execution System). Critical process parameters—temperature, pressure, speed, and time—are locked within the system and can only be adjusted by authorized engineers. Every batch undergoes first-article and last-article inspection and comparison.

   

  Customer Value: Parameter lockdown means consistent parts across batches, shifts, and production runs. Customers never receive a "bad batch" due to operator error.

   

  3.2 Dimensional Stability Control

  PEEK is sensitive to cooling rates, and its mechanical properties depend heavily on its degree of crystallinity. PEEK crystallizes evenly only when the mold temperature is uniform. Ansix Tech employs mold temperature controller zoning to maintain core and cavity temperature differences within 2°C, minimizing warpage and deformation. For a typical bracket product, three consecutive batches produced over one week showed key hole spacing fluctuation ≤0.02mm.

   

  Customer Value: Dimensional stability means seals fit valve bodies consistently, eliminating assembly rejects and field leakage.

   

  3.3 Core PEEK Injection Molding Parameters

  PEEK injection molding is considered the "ultimate challenge" in molding due to its ultra-high melting point (approx. 343°C) and rapid crystallization characteristics. Ansix Tech maintains precise control over the following critical parameters:

   

  Parameter Recommended Range Impact on Quality

  Material drying 150-160°C, 3-4 hours, moisture <0.02% Prevents hydrolysis, bubbles, brittleness

  Melt temperature 370-400°C Too low→poor melting; too high→gas degradation

  Mold temperature 160-200°C (typically 175-190°C) Controls crystallinity; low temp→warpage

  Injection pressure 80-120 MPa packing pressure Compensates for crystallization shrinkage

  Injection speed Medium to high Prevents premature cooling

  Cooling time Extended (longer than conventional thermoplastics) Ensures complete crystallization

  The company uses oil temperature controllers or cartridge heaters to achieve and maintain these high mold temperatures.

   

  3.4 Appearance Quality Standards

  Ansix Tech achieves multiple appearance quality tiers:

   

  Transparent parts: No bubbles, no flow marks

   

  Plated parts: No gas marks

   

  High-gloss parts: Surface roughness Ra≤0.2μm

   

  Printed/coated parts: Pre-compensation for deformation, print registration accuracy ±0.1mm
