Machined Laminate Insulator Bracket Set
A two-part machined laminate bracket set with a stepped body, rows of small drilled holes and machined steps. The laminate is backed at the exit face so the holes and thin sections do not delaminate at breakout.
Material
Engineering Plastics G-10 glass-epoxy laminate
Tolerance
Hole position ±0.05 mm
Process
CNC Milling
What This Part Does And What Matters On It
The function of the part, the features that carry the fit, and the requirements that decided how it was machined and checked.
This is a two-part machined bracket set cut from an orange laminate sheet. Each part has a stepped body, a row of small drilled through-holes along one edge and machined steps that locate against the mating component. Laminates of this kind are chosen where a bracket has to insulate electrically or stay dimensionally stable in a warm enclosure, and they machine very differently from aluminum.
The features that matter in use are the hole row and the step faces. Small holes in a laminate break out on the exit side if the material is not backed, and the thin sections between holes chip if the cutter exits unsupported. On this set the parts were machined face-down on a sacrificial backing with the hole row drilled last, so the exit faces stay clean and the steps stay square to the mounting face.
If you are specifying a similar part, tell us the laminate grade, the maximum voltage or temperature the bracket sees, and which face is the datum. Those three answers decide the material, the backing method and the order of operations.

How This Part Was Machined
Machined face-down on a sacrificial backing so the exit faces of the small holes stay clean, with the hole row drilled last and the steps milled with sharp carbide tooling to avoid delamination.
How This Part Was Checked
Hole positions and step faces from the mounting datum; exit faces inspected for breakout.
Hole row position and diameter
Step heights from the mounting face
Every Quote Comes With DFM Notes
Owen reads the drawing before pricing it: tolerances that add cost, features that need a second setup, finishes that change lead time. Send a STEP or PDF with the material and quantity, and the quote reflects what is actually machinable, within 24 hours on business days.
Material Certificates And Inspection Reports Travel With The Parts
Tell Owen which records your receiving inspection needs: mill certificates, first article report, CMM report, certificate of conformance, or all of them. They are agreed at quoting, not requested after the parts arrive.

A STEP, IGES, or PDF file with the material, quantity, and the tolerances that matter is enough to start. You get a price, a lead time, and manufacturability feedback from a real person, not a bot.
