PPSU mouse cage

FEATURES

• Foundational Hard Capabilities – Building Customer Trust Through Infrastructure

  1.1 Mold Processing Equipment

  Ansix operates a comprehensive suite of precision machining equipment that forms the backbone of its mold manufacturing capabilities:

   

  Five-Axis High-Speed Machining Centers: These machines enable the processing of complex curved surfaces with accuracy reaching 0.002mm. For PPSU mouse cage products, this translates directly to smooth, burr-free parting lines—a critical requirement for laboratory animal housing where sharp edges can cause injury to animals or compromise sterile environments.

   

  Slow Wire EDM (Electrical Discharge Machining): This technology enables the creation of micro-features including 0.03mm fine holes and narrow slots. For mouse cage designs requiring ventilation holes, water bottle interfaces, or intricate locking mechanisms, this capability ensures precision without inducing thin-wall deformation.

   

  Electrode Machining Center and EDM Workshop: Ansix maintains in-house electrode production and spark erosion capabilities, ensuring that mold repairs and modifications can be completed without outsourcing—typically restoring production within 24 hours for routine repairs.

  Ansix's injection molding press lineup spans 30 tons to 4,000 tons of clamping force, covering the full spectrum of PPSU mouse cage sizes—from small individual mouse cages to large rack-compatible systems.

   

  All-Servo Electric Drive Systems: Every machine is equipped with all-servo motor drives, delivering repetitive precision of ±0.1% . This means that every shot is consistent across million-plus production runs—a critical requirement when customers need batch-to-batch uniformity for regulatory compliance and animal welfare standards.

   

  1.3 Inspection and Metrology Equipment

  Coordinate Measuring Machines (CMM) : Each mold undergoes full dimensional reporting before shipment, with critical dimensions verified at CPK ≥ 1.33—demonstrating that the process is statistically capable of meeting specifications.

   

  Optical Imaging Inspection Systems: These systems enable rapid, non-contact measurement of complex geometries, ensuring that every feature—from ventilation slot dimensions to lid sealing surfaces—meets design intent.

• Mold Manufacturing Core Competitiveness – Speaking the Language of Customer Value

  Section III: Injection Molding Process Control – Eliminating Customer Quality Anxiety

  3.1 Process Standardization and MES Integration

  All injection molding machines are networked and integrated with a Manufacturing Execution System (MES) . Key process parameters—temperature, pressure, speed, and timing—are locked within the system, accessible only to authorized engineers for adjustment.

   

  First-Article and Last-Article Inspection: Every production batch undergoes comparison between first and last shots, ensuring process stability throughout the run.

   

  3.2 Dimensional Stability Control

  PPSU is a high-performance engineering plastic known for excellent heat resistance, impact strength, and chemical durability. However, its high processing temperature (typically 300–350°C melt temperature) demands precise thermal management:

   

  Mold Temperature Control: Ansix employs zone-controlled mold temperature controllers with temperature differential between core and cavity maintained within 2°C—significantly tighter than the industry-standard range of 120–180°C. This precision minimizes warpage and distortion.

   

  Real-World Validation Data: For similar structural components, three consecutive production batches over one week showed critical hole spacing variation ≤ 0.02mm.

   

  Ultrasonic Wall Thickness Monitoring: Real-time sensors provide feedback on wall thickness fluctuations, automatically compensating holding pressure to maintain dimensional consistency.

   

  In-Mold Temperature and Pressure Sensors: Closed-loop control systems enable real-time process adjustment, ensuring every shot meets specifications.

   

  3.3 PPSU Material Processing – Critical Parameters

  PPSU is highly moisture-sensitive; inadequate drying leads to hydrolysis, splay marks, and degraded mechanical properties. Ansix adheres to rigorous drying protocols:

   

  Parameter Specification Industry Standard Reference

  Drying temperature 135–177°C 150–170°C recommended

  Drying time 4–8 hours 4–6 hours typical

  Maximum moisture content < 0.02% 0.05% (500 ppm) maximum

  Injection Parameters:
