Directives de fabrication pour le PEEK<\/h3>\n<\/div>\n
\n

Contr\u00f4le thermique :<\/strong>
\nPEEK has low thermal conductivity. Heat generated during cutting stays in the part, which can cause size variation or melting. We use air blast or clean coolant to manage temperature.<\/p>\n

Outillage :<\/strong>
\nWe use positive-rake, sharp carbide tools. PEEK is abrasive (especially glass\/carbon-filled grades), so diamond-coated (DLC) tools are often used to extend tool life and maintain finish.<\/p>\n

Bridage :<\/strong>
\nThough hard, PEEK is a plastic. Excessive clamping force will deform it. We use vacuum fixtures or soft jaws with regulated pressure to hold parts securely without distortion.<\/p>\n

Recuit :<\/strong>
\nFor critical tolerances, we rough machine the part, anneal it in an oven to release stress, and then finish machine it to final size. This is a standard procedure at Jucheng.<\/p>\n<\/div>\n

Principaux secteurs d'application<\/h3>\n

Implants m\u00e9dicaux (ISO 13485)<\/strong>
\nPi\u00e8ces cl\u00e9s :<\/em> Spinal cages, bone screws, dental healing caps.
\nWhy PEEK:<\/em> Biocompatible, radiolucent (invisible to X-rays), and has an elastic modulus similar to human bone.<\/p>\n

A\u00e9rospatiale<\/strong>
\nPi\u00e8ces cl\u00e9s :<\/em> Cable clamps, bushings, thermal insulators.
\nWhy PEEK:<\/em> Replaces metal to save weight while withstanding high temperatures and aggressive aviation fluids.<\/p>\n

P\u00e9trole et gaz<\/strong>
\nPi\u00e8ces cl\u00e9s :<\/em> Backup rings, valve seats, electrical connectors.
\nWhy PEEK:<\/em> Withstands high pressure, high temperature (HPHT), and corrosive downhole environments.<\/p>\n

Semi-conducteur<\/strong>
\nPi\u00e8ces cl\u00e9s :<\/em> Wafer handling tools, vacuum wands.
\nWhy PEEK:<\/em> High purity, low outgassing, and resistance to harsh chemical etching processes.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
