    • Hethel Engineering Centre Chapman Way, Hethel Norwich, Norfolk UK NR14 8FB t: +44 (0) 1953 859 133 e: info@atprecision.co.uk atprecision.co.ukBUSINESS INTRODUCTION
    • Mould Solutions A process innovation positioned betweencasting and injection moulding technologies Injection moulding low pressure hot melt moulding casting temperature
    • LPIM Processing SolutionsWhy 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
    • LPIM Processing SolutionsWhy 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
    • LPIM Material SolutionsInnovative 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 5
    • Processing SolutionsMould Process Solutions
    • Processing SolutionsLow 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.
    • Processing SolutionsLPIM Indexing Table Description Low Pressure Over Moulding equipment Manual Load, Automatic mould rotary based low pressure mould system Other design variants available on request Control System PLC Typical product Cycle Time Product/Shot size specific, 10-40s typical Volume >1M components / year Locations used Mexico, China and Slovenia 8 Proven equipment technology
    • Processing Solutions A DIVISION OFSolo II LPIM Mould System Description Low Pressure Over Moulding equipment Manual Load, manual slide index for use with the low pressure mould system Other design variants available on request Control System Electronic Typical product Cycle Time Product/Shot size specific, 10-40s typical Locations used NEW Product launching Q4-11 Solo II : Horizontal Bolster Solo II : Vertical Bolster 9 Product designed to meet market requirements
    • Tooling SolutionsFull Tools Supplied (Bolster and Inserts) • A range of tool bolster sizes and material types are available • Tool design and development is offered as part of the engineering service solution
    • Processing SolutionsElectric 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
    • Processing SolutionsElectric 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
    • • 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
