Preparation before Installation of Machine

Author:HAIFLY MACHINERY Date:2011-12-6 0:43:16

  Preparation before Installation of Machine

1.1  Preparation before installation

l        Use the proper operating medium (hydraulic oil) and lube

Please refer to Chapter 9 for details.

l        Electric power network and water supply utility:

Before installing injection molding machine, electric network and water supply system shall be established firstly so that the future training on machine installation, commissioning and mold plastic will be as timely as scheduled.

As some dimension and wiring of your machine may be slightly different from what is shown on drawings attached, electric network and water supply system shall be established to the extent that all these changes could be allowed.

 

1.2  Lifting, unloading & conveying of injection molding machine

l        Lift up the injection moulding machine with the hoist and carrier that are strong enough (such as crane, winding gear, hook, wire rope, and etc.)

l        A layer of cloth or wood block must be put in between wire rope and injection molding machine components that are to be lifted up so as to prevent any damage to components such as tie bar and guide pin.

l        Try to keep machine steady and in a horizontal state when lifting.

l        Wood blocks and other pads could not be removed until all lifting, unloading and carrying work have been finished. 

 

1.3   Visual inspection

l        Check to see any visual damage on injection moulding machine.

l        In case of damage, please contact our sales representative or the nearest sales office.

 

1.4   Installation

l        Check and make sure of the injection molding machine’s dimension and location of adjustable iron. Please see Chapter 8 for details or contact us directly.

l        Installation location:

Location for installation shall be free of moisture and dust with adequate space to ensure operator’s safety, and proper ambience could help prevent injection machine from being soiled.

Installation shall be carried out in a space where all kinds of items necessary are accommodated. (The diagram is omitted)

l        Installation of precision injection molding machine

At the time of building concrete foundation, all contoured drawings and ground plot of the standard injection molding machine attached shall be read carefully to understand the true dimension of concrete ground.

If the leveling pad is used as vibration-proof tool, please put it into the bolthole in the ground before installing hydraculic injection molding machine onto the hard concrete foundation, and measure the level of machine by putting a set of high precision level gauge on its tie bar.

 

1.5   Components’ installation

Re-install the components and parts (e.g, hopper) that are dismantled during shipment to the injection mould machine.

 

1.6   Impregnation of operating fluid

Viscosity of operating fluid is recommended to be 68CST/400C (Please see Annex A).

l        Impregnate the clean operating fluid via air filter till the upper limit of level gauge is reached. Start the machine after wiring is finished and check the level of oil tank. If level is shown below medium reading, refuel the tank to make sure of higher level than medium reading. (Diagrams omitted).

l        For impregnated volume of operating fluid, please refer to the property & specifications table in Chapter 8. Please note that the volume in the table covers the fuel capacity of the whole cylinder, which explains why the operating fluid might be overflowed.

 

l        Notes:

a)      No mixing of different-branded operating fluids;

b)      Please see Chapter 9 or consult our sales representative or our oil supplier on how to choose proper operating fluid;

c)      Please do not start up machine until three hours later after operating fluid has been filled so as to facilitate the gas venting.

 

 

 

1.7   Electric Wiring

l        Take a fuse with proper nominal for 3-phase AC power.

l        Connect the cable to the main terminal board of the electric cabinet with power of 380V/3 Phase or 220V/3 Phase.

l        If the drive motor of pump rotates in reverse direction, exchange the connecting way of 2-Phase live wire.

l        To prevent any creepage, a conducting wire must be connected to the bottom box at the side of injector, while the other end connected to the ground rod or welded to a copper plate, and finally covered up into the land that the soil is inclined to be damp.

1.8   Cooling water pipe layout

Cooling water pressure could be 2-10kgf/cm2

l        Pipe & Discharge

Theoretically, cooling water pipeline for heat exchanger and mold injection seat shall supply cooling water via different lines, while in fact cooling water is supplied from the same access. Please note that the cooling water for heat exchanger shall be supplied before molding starts.

l        Drainage of cooling water:

a)      Stop water supply after molding ends and discharge cooling water out of cooler.

b)      Cooling water should continue its circulation under relatively low pressure during the temporary shutdown of machine in winter season. (In case of iced cooling water during cold nights, discharge the cooling water inside the cooler and remove the remainder by compressed air to prevent any damage to the cooler and other devices).

l        Cooling water flow:

Cooling water flow changes subject to other factors including molding status, water temperature, ambient temperature, cleanness of cooler and etc. The flow listed in the tables (omitted) acts as reference instead of standard.

& The flow rate of cooling water in coolerthe temperature of hydraulic oil must not exceed 55 when putting in use

1.9  Cleaning after installation

l        Antirust oil painted on components that are not coated can be cleared off by gasoline or kerosene (No smoking or fire at site).

l        Components with hard chrome plating on surface (such as tie bar, guide pin and piston rod) shall be carefully cleaned to delete dust and dirt to avoid damage to some seal ring.

l        Have each movable component coated with proper lube after cleaning is finished.

1.10              Use of lube

l        Use the proper lube. Non-standard lube of high viscosity may fail to lubricate or lead to insufficient lubrication.

l        For central lubricated parts, check carefully the total lube volume of central lubrication system before lubricating starts.

l        For details on lubricated location and lubricating method, please refer to the schematic diagram in Chapter 8.

 

1.11              Inspection

Inspect all fixed screws and pipe jointers and see if fixed screws in hydraulic and electric system are loose and fasten if any. Please conduct irregular inspection on the running status of each component during the operation.
