PRODUCT AND SUPPLY SCOPE
What We Supply
Supply is subject to grade, size, geometry, quantity and order requirements.
Cast Nylon Rods
Full-length stock or cut blanks for local or supplied machining.
Cast Nylon Tubes
Hollow blanks for bushings, sleeves, rollers and cylindrical parts.
Cast Nylon Sheets & Plates
Flat stock and cut blanks for pads, liners, guides and profiles.
Near-Net-Shape Blanks
Closer blank forms reviewed around finished geometry and allowance.
Rough-Machined Components
Semi-finished supply with selected allowance for local finishing.
Custom-Machined Finished Parts
Drawing- or sample-based components with agreed inspection scope.
FLEXIBLE SUPPLY STAGES
From Semi-Finished Material to Ready-to-Install Parts
Some buyers need stock shapes for local machining. Others need a closer blank, a semi-finished item or a fully machined and inspected part. CORETRUST helps define the supply stage around the buyer’s process, drawing and delivery needs.
