Construction of Injection Molds

Atlas Precision, Inc. tool construction meets the demands of the particular application. We keep things simple: simple to assemble, disassemble injection-molds-atlas-precision-productsand simple to maintain. Atlas Precision, Inc.  high-cavitation tooling consistently exceeds customer expectations for trouble free performance and longevity. Please note:

  • Structural Integrity
    • Modulus of base plates, rails and support columns is carefully engineered to maintain a flat parting line at cycle speeds, loads and temperatures.
    • Compression, tension and bending calculations are made and tool steels, hardness, and surface coatings are expertly selected.
    • Ejector plates are designed to carry injection as well as ejection loads
  • Mechanical Function
    • Safety and simplicity are first and foremost considerations.
    • Horn pins are designed with removable caps for easy maintenance.
    • Every mechanical action component is designed with handling and maintenance in mind.
    • Ejector pins are shoulder guided in the retainer plate and vent relieved.
    • Accelerated ejection is always used to free parts from lifters.
  • Thermal Expansion
    • Steel expansion is calculated at cycle-speed temperatures to prevent premature component wear.
  • Cooling
    • Tool and component temperature control is maintained in each segment of the tool at cycle speed.
    • Water volumes in each cooling segment are calculated to maintain uniform temperature profile and achieve maximum temperature removal rate.
  • Venting
    • Active vent pins are used when applicable.
    • Direction of gasses to outside and away from internal components.
    • Large leader pin vents are used to facilitate cleaning.
  • Materials
    • Steels and coatings are selected to optimize tool life and enhance heat exchange.
    • Non-ferrous metals and specialty materials are used to speed or retard the removal of temperature when appropriate.
  • Hot Runner Systems
    • Plug boxes are designed with clearance and handling considerations in mind.
    • Maintenance ease, service considerations and next day component availability are required to be demonstrated by the hot runner supplier before system selection is made.
    • Top Half and Stack Mold center sections must be approved by Atlas designers and satisfy Atlas safety and maintenance requirements before system selection.
    • Mold Straps and handling instructions are provided with every tool.
    • Identification and nameplates are installed on every tool.
    • Water line identification and sequence and volume requirements are indicated.
    • Electrical wire schematics and wattage requirements are indicated when applicable.
