CAN MAKINGSet an automatic lining machine to apply sealing compound to steel can components
level: 3
credit: 10
planned review date: November 2009
sub-field: Manufacturing Skills
purpose: This unit standard covers the setting of automatic lining machines of capacities up to 500 parts per minute to apply sealing compounds to steel can components fed automatically. Compound applicator guns may be mechanically operated, electrically operated with coil and stepping motor, or electropnuematically operated.
People credited with this unit standard are able to: check sealing compound and fill a sealing compound tank; dismantle and assemble sealing compound application guns; set sealing compound application guns; perform a setup; test run; and perform quality control checks on product from an automatic lining machine.
entry information: Open.
accreditation option: Evaluation of documentation and visit by NZQA.
moderation option: A national moderation system of regional panels and assessor networks has been established by Competenz.
special notes: 1 Definitions
Key points describe anything that may: result in the success, or otherwise, of a given job; cause injury or damage; or make the task easier to perform.
Key steps are actions that must be done, as a logical sequence of an operation, to advance the work.
Product specifications refers to the documented requirements of the manufactured item.
Setup, in the context of this unit standard, is synonymous with the term changeover. Either term may be used in the reading and interpretation of this unit standard.
Worksite procedures means all documented operational procedures put in place by the candidate’s employer. These include: site safety procedures; equipment operating procedures; standard job procedures; and procedures for the handling and disposal of materials and waste.
2 All work practices must meet recognised codes of practice and documented worksite safety procedures (where these exceed the code) for personal, product, and worksite safety, and must meet the obligations required under current legislation.
3 Legislation relevant to this unit standard includes but is not limited to the: Health and Safety in Employment Act 1992; Resource Management Act 1991; Hazardous Substances and New Organisms Act 1996.
