Fabrication Guidelines for PBT<\/h3>\n

Thermal Sensitivity:<\/strong> PBT is sensitive to heat during cutting. We use sharp, high-rake tools and optimized feed rates to prevent the material from softening or melting on the cutting edge.<\/p>\n

Low Moisture Absorption:<\/strong> PBT absorbs very little water, meaning it holds its dimensions much better than Nylon. This allows for tighter initial clearances in mechanical assemblies.<\/p>\n

Brittle Behavior in GF Grades:<\/strong> Glass-filled PBT is brittle. We use optimized entry and exit strategies to prevent “chipping” at the edges of the part.<\/p>\n<\/div>\n

Primary Application Industries<\/h3>\n

Automotive Engineering:<\/strong> Ignition system components, sensor housings, and exterior mirror parts requiring heat and solvent resistance.<\/p>\n

Electronics:<\/strong> Connectors, coil bobbins, and switch components requiring high dielectric strength and dimensional stability.<\/p>\n

Industrial Machinery:<\/strong> Pump impellers and valve bodies exposed to chemicals or high operating temperatures.<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"
