HTV- Production of seal-rings
Common Parameter For sprueless production and high quality parts
LSR-Injection Systems
Injection alternativs and Coldrunner Systems Coldrunnersystem with shut-off Nozzle-drive central mould related
KKS – standardized Fixed on the injection unit
KKS – standardized One coldrunner for different moulds
Coldrunner system 4 nozzle low construction System
unchangeable interaxes 50x50
Injection Systems Open Coldrunner-Systems
Advantage
Disadvantages
Multi cavities Small oversizes Low costs
high preasure loss undefined Hot / Cold separation low injection volume
Injection Systems Shut-off-systems
Advantage low pressure loss controlable defined Hot / Cold separation high volume/nozzle
Disadvantage limited cavities high oversizes
Standard Coldrunner Systems up
1cav 146 x 146 mm
to
32cav 246 x 296 mm Our benefits • Standard coldrunners for LSR / HTV • Coldrunners for rubber • 2-K technologie in LSR / Rubber / Thermoplast
Standard Coldrunner Systems Advantage • sprueless production • reduced cycle time • direct injection
• excellent injection point • accurate filling and closure of the cavities • sprueless 2K-Technology possible • fully automatic production
Standard Coldrunner Systems Specification • fully balanced • valve unit • with chokes (from 2 drop) • fully balanced and ready for production
Standard Coldrunner systems Valve unit with choke
Standard Coldrunner Systems Valve unit without choke
Mini to Magnum Standard nozzles for lots of applications
shot weight per nozzle from 0,5 g to 60 kg for LSR
Mini to Magnum Nozzle typ Discreption
Range of use
Mini
Small interaxes-Multi cavavities.
LSR
Standard
This nozzle is the Allround nozzle. It works with LSRHTV-Rubber low viskosity Exellent cooling With changeable tips
LSR / Gummi
Midi
LSR/Gummi
Maxi
Bigger hole to reduce the pressure los
Gummi
Magnum
Injection for high volume LSR up to zu 60kg Rubber nozzle for rubber up to 80 shore
Gummi
Central and decentral Fixed on the injection unit
Standard-nozzle for Direct Injection
Concept Maxi nozzle / Central nozzle with integrated piston fixed on the injection unit
Special Nozzle / Central nozzle for direct injection fixed on the injection unit
Dipping Nozzle KKE 54 (without shut-off )
Arburg Nozzle
EDZ-Nozzle
Injection screw with central nozzle and drive mechanism
Shut-off single nozzle, decentral, mould related Feed supply by tube , with hydraulic drive
Example: decentral nozzle
= possible variations of injection
Accessories
Standard-components for quick change and cost reduction
Maxi-nozzle With changeable tips – heightened flow channels for HTV and low viscosity rubber
Magnum-nozzle
Nozzle with separate cooling core-changeable tips-enlarged holes-for rubber high viscosityLSR up to 60kp-high pressure up to 3000 bar
Modular manifold 4 drops
