Core and cavity are the two halves of a mold used in injection molding process.

• Core is the part of the mold that creates the internal features of the plastic part.

• Cavity is the part of the mold that creates the external features of the plastic part.

• Core and cavity are designed to fit together to create the final shape of the plastic part.

• The molten plastic is injected into the cavity and takes the shape of the core.

• The core and cavity are usually made of hardened steel to wit...read more

Injection moulding is a manufacturing process used to produce parts by injecting molten material into a mould.

• Molten material is injected into a mould cavity

• The material solidifies inside the mould

• The mould is then opened and the part is ejected

• Commonly used for producing plastic parts

• Can also be used for producing metal, glass, and ceramic parts

OEE can be calculated by multiplying Availability, Performance, and Quality percentages.

• Calculate Availability by dividing Operating Time by Planned Production Time.

• Calculate Performance by dividing Actual Production by Maximum Production.

• Calculate Quality by dividing Good Units by Total Units Produced.

• Multiply Availability, Performance, and Quality percentages to get OEE.

Injection moulding machines are classified based on their function, structure, and control system.

• Based on function: hydraulic, electric, hybrid

• Based on structure: vertical, horizontal, multi-component

• Based on control system: manual, semi-automatic, automatic

• Examples: Arburg, Engel, Krauss Maffei
