3.1

molding machinery

machinery used to make sand molds

3.2

molding line

equipment used to make ready-to-pour sand molds

Note 1 to entry: A molding line consists of molding stations (automatic molding machines for complete molds) or several molding machines (molding group) that produce the molding parts separately. It can also include lines for core setting, mold closing, weighting or clamping, pouring, cooling, knocking-out of the mold parts and emptying of the boxes as well as integral transfer systems linking the various stations and lines.

3.3

coremaking machinery

machinery used to make solid and/or hollow cores

3.4

core shooter

machine where compressed air is rapidly expanded via the sand reservoir into the sand

Note 1 to entry: After expanding, the sand is then fluidized by the airstream and the sand–air-mix is transported into the core box. Typically used for cold box, hot box and inorganic binder (3.20) systems.

3.5

coremaking line

equipment used to make ready-to-use single cores and/or core assemblies

Note 1 to entry: A line can consist, for example, of a sand preparation equipment, coremaking machinery (3.3) , equipment for handling, deflashing, assembling, coating (3.22) and drying of cores.

3.6

sand mixer

machine in which the sand with bonding agents are mixed and conveyed to the discharge gate either batch or continuous type

Note 1 to entry: Typically, in the continuous type, the mixing takes place by screw-type mixing principles.

Note 2 to entry: Typically, in the batch type, the mixer consists of a circular container in which rotating ploughs and/or mill wheels (mullers) are mounted.

3.7

reclamation equipment

equipment including storage and conveying facilities used for the reclamation of used sands by mechanical and/or thermal processing means

Note 1 to entry: Machines used to destroy the binder (3.20) by thermal and/or mechanical and/or chemical/physical means.

3.8

sand lump crusher

machine used to break down lumps of used sand by mechanical means

3.9

magnetic separator

machine used to separate ferro-magnetic material from the used sand

3.10

gassing equipment

central supply systems and equipment used to produce and/or condition reactive gasses and supply them to the gassing station or into the sand mixture

3.11

knock-out equipment

equipment used to separate castings from the molding box, the mold and/or cores from castings

Note 1 to entry: Typical principles are vibrations on grids and trays.

3.12

punch-out equipment

equipment used to separate the mold and castings from the molding box by vertical or horizontal movement of a punch-out piston

3.13

set-up control mode

one or more groups of interlinked machines operated in set-up mode ここで, all steps within a process can be initiated separately and manually in any sequence

Note 1 to entry: Initiation of individual movements by hold-to-run without interlocked movements. Set-up control mode can enable certain functions of the machinery to be controlled with guards open or with protective devices muted or by means of a special control device such as a pendant control or a remote-control device, instead of the control devices used for normal operation (3.14) by trained personnel (3.17) which is authorised for this special task.

3.14

normal operation mode

normal operation

one or more groups of interlinked machines operated in normal mode during a period (e.g. an eight-hour shift) of regular production and directly production-related human interactions

Note 1 to entry: Directly production-related human interactions are defined as interactions done at least once per shift and does not include repair (3.16) .

3.15

maintenance

combination of service (3.15.1) and inspection (3.15.2) of the equipment

3.15.1

service

measure to maintain the nominal condition

Note 1 to entry: The nominal condition can be maintained in general without dismantling/disassembling major parts of the equipment, e.g. cleaning, lubrication of the work equipment as well as addition or replacement of agents or by replacing tools or operational changing parts.

3.15.2

inspection

measure to observe and assess the current condition as well as fault finding

Note 1 to entry: Measures, e.g. measuring, testing, diagnostics, troubleshooting including the determination of the causes of wear or damage and the derivation of the necessary consequences for the continued use.

3.16

repair

non-regular work, not foreseeable, required to re-establish the nominal condition

Note 1 to entry: Measure to replace damaged parts, requires in general dismantling/disassembling.

3.17

trained person

trained personnel

skilled person with system knowledge, background knowledge, experience and/or ability to perform a specific task and are aware of the hazards related to their duties

3.18

remote access

machine control mode where faults can be diagnosed, parameters changed, and machine functions can be initiated from a remote location

Note 1 to entry: Collecting data or monitoring machine parameters is not considered as remote access.

Note 2 to entry: Diagnosis by means of passive monitoring of machine parameters is not considered as remote access. Diagnosis by means of active intervention is considered as remote access.

3.19

molding material

basic granular material for making cores and molds (sand) and powder additives

Note 1 to entry: Sand can contain, e.g. silica, chromite, zircon, syntetical sands.

Note 2 to entry: Powder additives can contain, e.g. bentonite, coal dust, starch, iron oxide, wood flour, silica derivate.

3.20

binder

liquid component for making cores and molds and powder additives

3.21

catalyst

gase or liquid component for making cores and molds

Note 1 to entry: Catalysts can contain, e.g. amines, SO₂, methylformiate.
