Safety instructions The HPS III hot runner system conforms to the machinery directive 2006/42/EG and has been designed, manufactured and checked for safety according to the applicable safety rules and legislation and the state of the art. The HPS III hot runner system is delivered in perfect working order.
Safety instructions 2.1.1 Signal words for hazard classification HAZARD! indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury. WARNING! indicates a potentially hazardous situation which, if not avoided, will result in death or serious injury. CAUTION! indicates a potentially hazardous situation which, if not avoided, will result in minor injury or material damage.
Any different and unintended use is excluded and may result in personal injuries and material damage. Warranty expires in this case. EWIKON hot runner systems and single nozzles are only to be used for injection moulding applications, assembled in an enclosed injection mould. They are used to process thermoplastic resins according to their individual processing requirements and to pass them gently from the injection unit to the cavity by optimum temperature distribution and flow paths.
Safety instructions 2.5 Personal Protective Equipment (PPE) Wear the necessary protective equipment when working on or near the machine. Special information on the personal protective equipment in the work area has to be observed. 2.5.1 Symbols of the personal protective equipment Always wear the following when carrying out any work: Protective clothes: To protect your body wear tight-fitting clothes with low resistance to tearing, without protruding parts and with long sleeves and long trousers.

Safety instructions Risk of burns • Hot surfaces Many components of the hot runner systems get very hot and may cause severe skin burns when being touched. • Hot material (plastic melt) Never touch material leaking from the nozzle/the mould/the hot runner or the material inlet. Even material that seems to be cooled down already may still be hot inside the core and cause burns.
The use of non-OEM spare and wear parts as well as auxiliary material may pose risks. Only use original parts or parts approved by EWIKON Heißkanalsysteme GmbH. Only use auxiliary and operating materials which are suitable for their intended use (compare chapter „5.3 Technical Requirements“).

Installation 5. Installation The following information is intended to help you install the HPS III hot runner system. In addtion, the assembly staff has to have the know-how required to install an HPS III hot runner system. The described installation processes are examples for standard nozzles and standard systems. Special systems may require different procedures! Please observe the instructions in the order specific documents. 5.1 Transport This chapter describes how to transport a hot runner system without damaging it and how to ensure occupational safety for the staff.
• • Spacer bolt for attachment swivel (allowed for L2X systems only, can only be purchased from EWIKON). The spacer bolts must not be used for other transport processes! See PPicture 6. They should only be used when attach- ment swivels can not be used for lack of space.
Before transport the working load limit for the used lifting accessories and slings must be checked in the following order: 1. How heavy is the load? • The weight of single components, systems or hot halves is indicated on the EWIKON note of delivery (net weight, without packaging). If this information is not available anymore the weight can be estimated. However, there should be a sufficient margin up •...
Page 23
Installation 3. Is one single attachment point sufficient to lift the load vertically stretched or is more than one attachment point necessary to lift the load? Only for the transport of hot halves, nozzle sides or individual mould plates usually one single attachment point is suffici- • ent (see Picture 13) as the gravity centre usually coincides with the attachment point! In this case the lifting capacity is 100 %.
Depending on the manufacturer and design of the attachment swivel the maximum possible load capacity must no longer be utilized. If the attachment swivels recommended by EWIKON are used for such installation work (see chapter „5.1.2 Recommended lifting accessories and slings“), the maximum load capacity of an attachment swivel should always be reduced by at least the half.

Installation Putting hot runner assemblies (hot halves, mould plates, manifolds or L2X systems) from lying (horizontal) into upright (vertical) position. 1. The hot runner assembly must be placed on an even, 100% load capacity non-slip surface. 2. Screw in attachment swivels and affix them to a crane. 3. Put a wooden lath on the working surface and secure against slipping.
Installation NOTE! Pay attention to system characteristics The work steps described just show how to move the system most commonly. Depending on the system layout further measures which have to be determined individually may be necessary to move and assemble hot runner assemblies in a safe way.

Dimensional check (for details please also see chapter „5.4 Checks before installation“) Check of the given installation dimensions, fit sizes, form and location tolerances of the mould plates surround- ing the hot runner system (for information please see the current catalogues in the download section on www. ewikon.com). The following dimensions have to be checked in particular: • Mould plate dimensions.
Page 28
Installation Protect the cable ends When wiring the system make sure that the thermo and power lines do not protrude from the outer edges of the mould and are protected against damage. The distances between hot runner and cables inside the mould have to be dimensioned in such a way that there is no damage to the components caused by excessive heat.

This causes damage in the gating geometry. When valve pins are operated in an unfilled system a clamping device must be provided in order to prevent the gate exchange inserts from being pulled out. Suitable solutions are the use of flat headed cylinder screws, clamping sleeves or retaining rings. Depending on the available installation space EWIKON can recommend a suitable clamping version. In general the start-up of valve gate systems is carried out analogous to other externally heated systems. (see chapter „6.3.1 First-time start-up and filling of a HPS III hot runner system“ and „6.3.2 Start-up of an already filled HPS III hot runner system“.
Instructions for the operation of valve gate systems 6.4.1 Machine downtimes > 5 minutes of systems with HPS III-S nozzles (system / single tip / single cavity) • For machine downtimes of more than 5 minutes the temperature of the hot runner system should be decreased (50°C - 60°C below processing temperature) in order to avoid thermal degradation of the material in the system.

Maintenance 7. Maintenance 7.1 Safety instructions WARNING! Hot surfaces / hot material (plastic melt) Body burns by hot surfaces. • Let the HPS III hot runner system and all components cool down completely to ambient temperature before starting maintenance work / disassembling. Never touch material leaking from the nozzle/the mould/the hot runner or the material inlet.
If a nozzle tip can not be screwed out use the controller to raise the nozzle temperature in steps. • If the nozzle tip is still not screwable please contact the EWIKON customer service. See chapter „7.7 Inst- ructions for service and repair“.
Two-piece nozzle tips always have a separate item number for each of their components. Tipp: In case that a cleaning of the flow channel of the nozzle is required EWIKON offers a maintenance mouthpiece with drill guide. See chapter „5.3.1 Tools and operating materials“. The maintenance mouthpiece is installed after the tip insert has been removed (replaces the tip insert). It allows the precise insertion of a drill bit to remove most of the frozen plastic in the flow channel. The diameter of the drill bit should be 1/10 mm...
