Relationships with occupations

Essential knowledge

Types of plastic is an essential knowledge of the following occupations:

Plastic heat treatment equipment operator: Plastic heat treatment equipment operators manipulate plastic products using machinery such as furnaces or flame-hardening machines in order to temper, anneal or heat-treat. They set up the machinery and read the production instructions to determine the furnace temperature. Plastic heat treatment equipment operators remove products from machines, let them cool down, examine and test products to see if they conform to specifications.
Plastic products assembler: Plastic products assemblers fit and fasten parts and finished plastic products according to strictly-defined procedures. Plastic products assemblers may also cut and shape plastic parts using hand, power, and machine tools.
Synthetic materials engineer: Synthetic materials engineers develop new synthetic materials processes or improve existing ones. They design and construct installations and machines for the production of synthetic materials and examine samples of raw materials in order to ensure quality.
Plastic furniture machine operator: Plastic furniture machine operators tend plastic processing machines that produce pieces such as plastic chairs and tables. They inspect each resulting product, detect abnormalities and remove inadequate pieces. In some cases, they may assemble different plastic parts to obtain the final product.
Cake press operator: Cake press operators set up and tend the hydraulic presses that compress and bake plastic chips into cake moulds to produce plastic sheets. They regulate and adjust the pressure and temperature.
Compression moulding machine operator: Compression moulding machine operators set up and operate machines to mould plastic products, according to requirements. They select and install dies on press. Compression moulding machine operators weigh the amount of premixed compound needed and pour it into the die well. They regulate the temperature of dies.

Optional knowledge

Types of plastic is optional for these occupations. This means knowing this knowledge may be an asset for career advancement if you are in one of these occupations.

Chemist: Chemists perform laboratory research by testing and analysing the chemical structure of substances.They translate the research results into industrial production processes which are further used in the development or improvement of products. Chemists are also testing the quality of the manufactured products and their environmental impact.
Medical device assembler: Medical device assemblers manufacture instruments, machines and appliances that can be used to prevent, diagnose or treat medical conditions. Medical devices can be non-electrical, such as tubes, needles, drainage sets and sterile pipettes, as well as electrical, such as pacemakers, MRI machines, and X-ray devices. Some may also work in the production of medical furniture such as hospital beds and operation tables.
Casting mould maker: Casting mould makers create metal, wooden or plastic models of the finished product to be cast. The patterns are then used to create moulds, eventually leading to the casting of the product of the same shape as the pattern.
Materials engineer: Materials engineers research and design new or improved materials for a diverse number of applications. They analyse the composition of materials, conduct experiments, and develop new materials for industry-specific use that can range from rubber, to textiles, glass, metals, and chemicals. They advise companies in damage assessments, quality assurance of materials, and recycling of materials.
Filing machine operator: Filing machine operators set up and tend filing machines such as band files, reciprocating files and bench filing machines in order to smoothen metal, wood or plastic surfaces by precisely cutting and removing small amounts of excess material.
Injection moulding operator: Injection moulding operators operate and monitor injection moulding machines, in order to cast products from thermoplastic materials. They regulate the temperature, pressure, and volume of plastic, according to pre-defined specifications. Injection moulding operators also remove finished products and cut-away excess material, using a knife or other hand tools.
Computer numerical control machine operator: Computer numerical control machine operators set-up, maintain and control a computer numerical control machine in order to execute the product orders. They are responsible for programming the machines, ensuring the required parameters and measurements are met while maintaining the quality and safety standards.
Toymaker: Toymakers create or reproduce hand-made objects for sale and exhibition made of various materials such as plastic, wood and textile. They develop, design and sketch the object, select the materials and cut, shape and process the materials as necessary and apply finishes. In addition, toymakers maintain and repair all types of toys, including mechanical ones. They identify defects in toys, replace damaged parts and restore their functionality.
Recreation model maker: Recreation model makers design and construct recreation scale models from various materials such as plastic, wood, wax and metals, mostly by hand.
Lacquer spray gun operator: Lacquer spray gun operators operate lacquer spray guns designed to provide otherwise finished metal, wooden or plastic workpieces with a hard, durable finishing coat, through lacquer coating or paint that is either matte, sheen or highly glossy, but is always meant for hard surfaces.
Plastic rolling machine operator: Plastic rolling machine operators operate and monitor machines to produce plastic rolls, or to flatten and reduce the material. They examine raw materials and finished products to make sure they are according to specifications.
Slitter operator: Slitter operators set up, operate, or tend machines, in order to cut, slit, bend, or straighten sheets of metal, paper, or other materials to specific widths. Slitter operators must also ensure quality, by examining various end-products and observing pre-defined tolerances.
Router operator: Router operators set up and operate multi-spindle routing machines, in order to hollow-out or cut various hard materials such as wood, composites, aluminium, steel, plastics; and others, such as foams. They are also able to read blueprints to determine cutting locations and specific sizes.
Brush maker: Brush makers insert different types of material such as horsehair, vegetable fiber, nylon, and hog bristle into metal tubes called ferrules. They insert a wooden or aluminium plug into the bristles to form the brush head and attach the handle to the other side of the ferrule. They immerse the brush head in a protective substance to maintain their shape, finish and inspect the final product.
Extrusion machine operator: Extrusion machine operators set up, monitor and maintain machines which heat or melt raw materials, and pull or push the heated material through a shaped die to form it into a continuous profile with a preset cross section such as tubes, pipes and sheeting. They may also clean and maintain the equipment.
Drill press operator: Drill press operators set up and operate drill presses designed to cut excess material from or enlarge a hole in a fabricated workpiece using a hardened, rotary, multipointed cutting tool that inserts the drill into the workpiece axially.
Foundry moulder: Foundry moulders manufacture cores for metal moulds, which are used to fill a space in the mould that must remain unfilled during casting. They use wood, plastic or other materials to create the core, selected to withstand the extreme environment of a metal mould.
Dip tank operator: Dip tank operators set up and tend dip tanks, which are coating machines, designed to provide otherwise finished work pieces with durable coating by dipping them in a tank of a specific sort of paint, preservative or molten zinc.
Chemical engineer: Chemical engineers design and develop large-scale chemical and physical production processes and are involved in the entire industrial process required for transforming raw materials into products.
Punch press operator: Punch press operators set up and tend punch presses designed to cut workpieces into their desired shape by propelling a hydraulic ram to punch holes into them with a single die set that pushes through the top dead centre, through the surface, and to the bottom dead centre of the workpiece.
