  2. Design of plastic components - Wikipedia

    en.wikipedia.org/wiki/Design_of_plastic_components

    Draft angle design is an important factor when designing plastic parts. Because of shrinkage of plastic material, injection molded parts have a tendency to shrink onto a core. This creates higher contact pressure on the core surface and increases friction between the core and the part, thus making ejection of the part from the mold difficult.

    Plastics can additionally be classified by their resistance and reactions to various substances and processes, such as exposure to organic solvents, oxidation, and ionizing radiation. [15] Other classifications of plastics are based on qualities relevant to manufacturing or product design for a particular purpose.

    Partial overlap box with interlocking slots to temporarily close box Corrugated plastic box used as reusable packaging. Corrugated box design is the process of matching design factors for corrugated fiberboard (sometimes called corrugated cardboard) or corrugated plastic boxes with the functional physical, processing and end-use requirements.

  6. High-density polyethylene - Wikipedia

    en.wikipedia.org/wiki/High-density_polyethylene

    HDPE is known for its high strength-to-density ratio. [4] The density of HDPE ranges from 930 to 970 kg/m 3. [5] Although the density of HDPE is only marginally higher than that of low-density polyethylene, HDPE has little branching, giving it stronger intermolecular forces and tensile strength (38 MPa versus 21 MPa) than LDPE. [6]

  7. Low-density polyethylene - Wikipedia

    LDPE has SPI resin ID code 4 Schematic of LDPE branching structure. Low-density polyethylene (LDPE) is a thermoplastic made from the monomer ethylene.It was the first grade of polyethylene, produced in 1933 by John C. Swallow and M.W Perrin who were working for Imperial Chemical Industries (ICI) using a high pressure process via free radical polymerization. [1]

  8. Packaging engineering - Wikipedia

    en.wikipedia.org/wiki/Packaging_engineering

    Packaging engineering, also package engineering, packaging technology and packaging science, is a broad topic ranging from design conceptualization to product placement. All steps along the manufacturing process, and more, must be taken into account in the design of the package for any given product.

  9. Plastics industry - Wikipedia

    en.wikipedia.org/wiki/Plastics_Industry

    Besides plastics production, plastics engineering is an important part of the industrial sector. The latter field is dominated by engineering plastic as raw material because of its better mechanical and thermal properties than the more widely used commodity plastics .
