CONSTRUCTION OF INJECTION MOLDS

Atlas tools are constructed to meet the demands of the particular application.We keep things simple, simple to assemble, disassemble and simple to maintain.

Atlas Precision 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.

 

• Safety
  • 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.
