Why Active Technologies?
When working with Active Technologies, you get the
benefit of working with a development team
spanning
• Component Design Knowledge
• Material Selection advice
• Creativity in mould process knowledge and material
combinations to meet specific application requirements
• Equipment supply
o Development of equipment to meet specific
manufacturing needs and capacity requirements
• Tooling Supply
o Valuable tooling input

4. LPIM Processing Solutions
Why LPIM? and Why it makes financial sense
Low Pressure Injection Moulding offers;
• Simple switch-on, switch-off technology
• Low pressure protects sensitive electronics
• Design opportunity, create structure from protection
• Clean, simple to use process, cycle times typically 30 seconds or less
• Strong adhesion to a wide range of substrates, in particular plastics
such as Nylon, ABS and PVC
and makes financial sense because;
• Reduces manufacturing costs significantly
• Makes low volume, high quality part manufacturing profitable
• ROI or PFI usually easy to calculate
• Low through life cycle support costs
• No end of lifecycle disposal time-bomb

5. LPIM Material Solutions
Innovative Materials
• A range of thermoplastic, copolymer, hot melt adhesives wet to the
substrate surface and making the part watertight, typically IP67
• Derived from natural, renewable resources, contains no toxic
compounds
• Process temperatures from 180 °C to 230 °C
• In-service temperatures for material range from – 55°C to +240°C
• Thermoplastic copolymer materials can be over-moulded in
engineering grade polymers or elastomers

Low Pressure Injection Moulding (LPIM) System
• Field-proven, all-electric technology delivers outstanding
durability and value.
• These melt units are ideal for all-electric dispensing via a mould
tool or manual/handgun packaging operations.
• Choose from tank capacities of 4, 10, 16, 25, 50 and 100 litres.
• Economize using fixed-speed AC drive and gear pumps with low and high output rates.
• Simplify daily operation using intuitive graphic operator interface, system status at-a-
glance and continuously updated temperature monitoring.
• Reduce wear and tear on equipment with low-pressure operation.
• Select 2-, 4-, or 6-gun operation and expand as your production needs change.
• Enhance performance of hot melt adhesives. Leading Zone Concept prevents any
control zone temperature from exceeding the leading zone temperature, causing all
zones to reach set point temperature simultaneously.
• Reduce adhesive spilling and waste with large, accessible tank opening.
• Access all components quickly and easily using large, removable side panels.
• Connect to a personal computer via RS 232 port for melter diagnostics, setup and
programming.

Electric Dual Process Moulding system features
• Field-proven, all-electric technology delivers
outstanding durability and value.
• These mould systems are ideal for all-electric
dispensing via a mould tool
• Ultra-quiet machine eliminates the need for hydraulic or
pneumatic connections by using electric servos for
motion control.
• Full-colour, graphical HMI touchscreen provides a user-
friendly interface for machine setup & operation.
• A configurable injection profile allows up to 5 injector
speed and acceleration changes, plus a packing stage
that can be enabled or disabled by the operator.
• Recovery can occur either before or after injection,
making the machine perfect for creating test specimens

12. Processing Solutions
Electric Dual Process Moulding System
• Servo technology provides precise speed & position control
• Velocity is held within 0.02%
• Position is held within 0.001"
• HMI touchscreen for setup, control, and monitoring
• Temperature control and monitoring
• English or Metric units selectable for data entry &
display
• Auto or manual modes
• Optional packing stage
• Built-in safety features prevent operation that may damage
machine
• Integrated chiller for feed throat and bearings
• Uses self-clamping V-mould technology (other mould
designs can be integrated)
• Optional data collection saves information about each shot -
perfect for engineering development environments.
• Allows placement near assembly areas to avoid having to
"batch mould"
• Can be easily integrated into a product assembly line

13. • Undertake process development by:
• Investment in People
• Investment in Equipment
• Build partnerships to adapt technologies for new process challenges:
• Polymer and Adhesive manufacturers
• Material processing equipment manufacturer
