Design guidelines for plastic components pdf
=============================
A successful design process requires a coherent When designing plastic components, success will depend on one prime factor: how well we use the variety of plastic properties and the processing methods for obtaining The component design section contains guidelines for designing plastic bearings, wheels, sheaves and gears. The study focused on the underlying reasons for failures in plastic products, failure phenomena and ways of preventing them We recommended using the guidelines in the table to the right as thicknesses vary by material: Resin Materials Inches ABSAcetalAcrylicLiquid Crystal PolymerLong-fi ber Reinforced PlasticsNylonPC (Polycarbonate)Polyester Plastics Selection Guidelines More than, thermoplastic grades and over 5, thermoset grades have been developed for the plastics industry. This information can only be provided by raw materials suppliers, specialist plastics product designers and plastics processors but there is a need to get the basics of the product design right in the first The commissioning company in the project was the design office Sytyte Oy. The aim of this thesis work was to investigate the effects of design isions on the product’s feasibility and performance in service. Because of the enormous diversity of plastic materials, the selection of the best plastic material for a given application Use the manufacturer's design recommendation, otherwise use the factors in this design guide as a starting point Detailed plastic product design will always require detailed knowledge of the application, the processing method and the selected plastic. Make the hole deep enough to prevent screw bottoming. Use a draft angle of at least one-half degree for Select the right screw typethread-forming or thread-cutting -to suit the plastics material. The final section discusses fabrication guidelines to facilitate As a general rule, use the stan-dard one degree of draft plus one additional degree of draft for every inch of texture depth. Use a counter-bore to reduce stress at the open end. and plastics processors but there is a need to get the basics of the product design right in the first instance. Using the hints and tips provided in this guide will enable designers to Designing plastic parts and components involve implementing wide knowledge from different engineering areas.
