Precision-Crafted Custom Aluminum Die Casting Molds for Motor Housings

(1) Scope of Customization Services

• Application Scenarios: Specifically designed for aluminum die casting molds of motor housings, suitable for home appliances, industrial motors, automotive motors, etc. Supports customization of shell structures for different power ratings (e.g., cooling ribs, mounting holes, junction boxes).
• Material Selection:
  • Mold steel options: P20 (pre-hardened plastic mold steel), 718 (high-polish mirror mold steel), H13 (hot-work die steel for aluminum casting), 45# steel (common structural steel), S136 (stainless steel mold steel, corrosion-resistant).
  • Materials are recommended based on customer requirements for mold life (e.g., batch production) and surface finish (e.g., H13 steel for high-life, high-wear resistance in mass production).
• Structural Customization:
  • Cavity Design: Single cavity (suitable for small-batch prototyping) or multi-cavity (improves mass production efficiency), with optimized runner systems to reduce porosity and shrinkage in castings.
  • Demolding Design: Customized lifters, slides, and other core-pulling mechanisms ensure smooth demolding of complex motor housing structures.
  • Cooling System: Built-in circulating water channel design shortens cycle time and improves production efficiency.

(2) Production and Quality Advantages

• Equipment and Precision:
  • Equipped with 100+ CNC machines (including 5-axis CNC) with a machining accuracy of ±0.001mm, ensuring high matching accuracy of mold parting surfaces and cavity dimensions.
  • Uses electrical discharge machining (EDM) and wire electrical discharge machining (WEDM) for precise processing of complex mold structures.
• Quality Control:
  • Full-process inspection: Raw material flaw detection → dimensional inspection after rough machining → hardness testing after heat treatment → coordinate measuring machine (CMM) full-dimensional inspection after finishing → trial molding verification (first article inspection report provided).
  • Certified to ISO 9001 quality management system, with mold life exceeding 50,000 cycles (depending on material and process).
• Environmental Compliance: Mold materials meet RoHS standards, lead-free and halogen-free, suitable for export to European and American markets.

(3) Service and Delivery Advantages

• Design Support:
  • Accepts customer-provided 3D drawings (STP/STEP/IGS, etc.) or offers reverse modeling services for customers without drawings (generating CAD models from scanned samples).
  • Professional engineering team provides mold structure optimization suggestions, such as improving gate location to reduce casting deformation.
• Flexible Collaboration:
  • Minimum order quantity of 1 piece, supporting small-batch mold testing (e.g., sample mold development) to reduce initial investment costs.
  • Negotiable tiered pricing for bulk orders, with value-added services like mold maintenance and repair for long-term clients.
• Global Delivery:
  • Main export markets: USA, Germany, UK, etc. Offers FOB Xiamen port or DDP door-to-door services, with shipping cycles of 15-30 days (depending on region).
  • Response time ≤2 hours, production schedule provided within 24 hours of order confirmation, with real-time processing updates.

(4) Customer Cases and Reputation

• Typical Cases:
  • Developed multi-cavity aluminum die casting molds for a German motor manufacturer, improving production efficiency by 40% and reducing casting defect rates below 0.5%.
  • Developed motor housing molds for a domestic new energy vehicle brand, supporting complex water-cooling structure design and passing IATF 16949 automotive industry certification.
• Market Feedback:
  • 99% positive rating from 103 customer reviews, praised for mold precision and on-time delivery (100% on-time delivery rate).
  • Over 100 long-term clients with a repurchase rate exceeding 80%, mainly in high-end manufacturing.
