Thin wall injection molding is a specialized form of conventional injection molding that focuses on mass-producing plastic parts that are thin and light so that material cost savings can be made and cycle times can be as short as possible. Shorter cycle times means higher productivity and lower costs per part.〔(PHJ4501: Superior Material For Thin-Wall Injection Molding by Jums Belezza, JG Summit Petrochemical Corporation, 2006 )〕 The definition of thin wall is really about the size of the part compared to its wall thickness. For any particular plastic part, as the wall thickness reduces the harder it is to manufacture using the injection molding process. The size of a part puts a limit on how thin the wall thickness can be. For packaging containers thin wall means wall thicknesses that are less than 0.025 inch (0.62mm) with a flow length to wall thickness greater than 200.〔 ==Markets== The trend towards thin wall molding continues to increase in many plastic industries as plastic material and energy costs continue to rise and delivery lead times are squeezed.〔(Products: Customer Demands for Thinner Walls and Lightweight Designs Pose Challenges for Moldmakers, Mold Making Technology Magazine, 6/20/2011 )〕 The following industries make use of thin wall molding: * food packaging ( e.g. food containers and lids)〔(wall packaging users are seeking more from less by Chris Smith, Injection World Magazine, April 2012 )〕 * automotive (e.g. both structural and non-structural car parts)〔(Up The Auto Industry by Chris Smith, Injection World Magazine, June 2012 )〕 * mobile telecommunications (e.g. mobile phone housings) * medical (e.g. syringes)〔(thin wall to create medical devices, by Clare Frissora and Greg Tremblay, Medical Device and Diagnostic Magazine, July 1, 2008 )〕 * computing equipment (e.g. computer housings) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Thin-wall injection molding」の詳細全文を読む スポンサード リンク
