Knowra Injection moulding Injection moulding Injection moulding forms parts by forcing molten or softened material into a mould, where it cools or cures before removal. It produces repeatable shapes, often in large volumes.
Injection unit : The machine assembly that melts or softens material and injects it into a mould. Its screw or plunger delivers the pressurized material that fills the cavity.
Thermoplastic : A polymer that softens when heated and hardens when cooled, usually without a chemical change. Thermoplastics can be melted for injection and solidified repeatedly.
Plastic bottle cap : A closure moulded from plastic to seal the opening of a bottle. Bottle caps are a common high-volume example of small, repeatable moulded parts.
Compression molding : A process that shapes material by pressing it in a heated mould, often while it cures. It uses compression rather than injection to fill the mould.
Mold flow analysis : Computer simulation of material flow, cooling, and defects during mould filling and solidification. It helps locate gates and predict filling problems before a tool is built.
Clamping unit : The machine assembly that closes, holds, and opens the two halves of a mould. It resists cavity pressure and separates the mould after the part solidifies.
Thermosetting polymer : A polymer that irreversibly forms a cross-linked network during curing. Unlike thermoplastics, thermosets harden through curing rather than cooling.
Automotive interior : The cabin components and surfaces inside a motor vehicle. Dashboards, trim, and housings often use moulded polymer components.
Blow molding : A process that forms hollow parts by expanding heated plastic against a mould wall. It is better suited to hollow containers than solid, detailed parts.
Gate (injection molding) : The opening through which material enters a mould cavity from its runner. Gate position and size affect flow, weld lines, and the visible gate mark.
