PETform TechnologiesHigh Performance Preform Moulds & Hotrunners
PET PREFORM MOULDS DESIGNED & BUILT TO-
- Produce high quality preforms
- Achieve fast cycle time
- Consume minimum energy
- Minimize mould change time
- Repair and service easily
- Provide a long and trouble free service life
FEATURES & BENEFITS-
Core lock type stack design
- Thread splits are locked in position by lock rings before mould closing to minimize wear of thread split tapers on the cavity side for a long flash-less service life of thread splits
- Preform collar is placed inside the thread splits to minimize clamping force requirement and resulting stress on the mould and clamping unit
Modular cavity construction
- Replaceable cavity lock ring; a wear part separated from cavity for inexpensive and easy replacement
- No axial load on cavity allowing the use of lower steel section thickness and faster cooling
Precision machined and finished
- Weight variation across cavities is minimal
- Excellent concentricity between core and cavity for minimum wall thickness variation
- Consistent dimensions across cavities
- Flash-less parting lines
- Good mould life due to perfect matching of components under load
Large gate diameter and generous venting
- Permits short injection and hold times
- Resin is exposed to less stress during injection
Thread splits manufactured from corrosion resistant steel
Gate thermally insulated from hot runner nozzle and aggressively cooled
- Low crystallinity in the gate area of the preform
Cavity and core manufactured from highly conductive, tough and wear resistant steel
- Fast and efficient cooling
- Highly resistant to mechanical failure
Wet area maximised in gate, cavity, thread splits and core
- Fast and efficient cooling
Cooling water channels in gate, cavity, thread splits and core, designed for turbulent flow at minimum flow rates
- Ensures fast and efficient heat exchange between steel and water
- Chilled water pump consumes less energy
- Requires a smaller flow rate pump
Large channel diameter for chilled water transport in mould base
- Low pressure drop in water distribution channels resulting in energy conservation
- Less pressure demand on the pump
All stack components hardened to over 50 HRC
- Highly wear resistant
- Resistant to plastic deformation and changes in dimensions
- Long service life
PVD coatings (optional)
- Extremely wear resistant to protect surfaces from wear
- Easier ejection with lower ejection forces
Mould base plates hardened and plated for corrosion resistance
- Highly rigid to withstand clamping forces without deformation
- Provides adequate support to stack components
- Extreme resistance to corrosion
- Long service life
Ergonomic
- Cores, core lock rings, thread splits, and cavity flanges can be changed with the mould in the machine, for quick and easy servicing
- Only one chilled water inlet and outlet for each mould section, with distribution channels drilled into the mould base plates, for quick mould change and low probability of water leakages
- Quick coupling connectors for quick mould change
Cavity Spacing as low as 40 mm x 100 mm for thread diameters of up to 25 mm and 45 mm x 100 for thread diameters up to 30 mm
- Permits the use of higher number of cavities for any machine size for higher productivity
Standardization of components
- Reduction in spares inventory for a group of moulds
- Easy servicing
Customized to fit any appropriate hot runner
Customized to fit any injection moulding machine
Support
