Custom plastic insulators

Machining to your component drawing and exact material specification.

CDS machines engineered plastics and documents existing parts for replacement. Send your insulator drawing, specification or sample records to confirm the particular material, form and machining scope.

Identify the individual insulator and its required revision, including any customer-specified changes to an existing part.

Photography plannedInsulator · supporting and mounting features
The component drawing specifies its outline, openings and mounting features.

Profile, holes and finished thickness

The insulator drawing defines the individual component. Outside shape, thickness, openings and attachment features each need dimensions and tolerances; an assembly image alone does not provide those details.

Outside profile, holes and thickness
  1. Profile follows the customer-specified component outline.
  2. Holes have individual sizes and locations.
  3. Thickness is the finished dimension between the faces.

Illustrative plate face and separate edge view. The drawing specifies the actual component geometry and grade; no electrical path, assembly or performance rating is shown.

Outside profile and thickness
Specify the finished outline, thickness and any steps, recesses or shoulders. Include the required reference faces, flatness or surface finish where called out.
Holes, bores and cutouts
Show their sizes, depths and positions relative to the drawing references. Identify any separately requested inserts or hardware for confirmation with the quotation.
Material and stock form
Provide the exact manufacturer grade, required stock form and any reinforcement-direction callout. A generic material name may not identify the specified material.

Your specified grade

CDS's broader material range includes G10, phenolic, Micarta, PEEK and ULTEM. The particular insulator grade, stock form, availability and machining scope, including reinforced-laminate work, require confirmation.

If your specification calls for ULTEM, see ULTEM machining for material information. Required material or inspection documents should accompany the inquiry; electrical, thermal and flame qualifications need explicit confirmation.

Replacing an existing insulator

Old drawings, equipment part records and an unworn spare can help document an unavailable component.

Known geometry and damaged features

Reverse engineering documents an existing part for manufacture. Burned edges, crushed faces, damaged holes and distortion may no longer represent the required dimensions.

Identify those areas and provide reliable dimensions where available. Unknown geometry or material requirements need clarification before machining. Customer-specified changes need an updated drawing and revision.

Material records for a replacement

A physical sample does not establish the original grade or its electrical, thermal or flame qualifications. Provide the existing material specification and any required records with the part details.

Request an insulator machining quote

Start with a drawing, specification, dimensioned sketch or details of an available sample. Identify the individual part and any separately requested items.

Component definition

Part number and revision; profile, thickness, holes, bores, cutouts and shoulders. Include specified tolerances, reference faces, finish and reliable dimensions for damaged sample features.

Material and records

Exact grade, required brand, stock form and reinforcement direction where specified. List permitted substitutions and required material, inspection or other documentation.

Order details

Quantity by part, repeat needs, requested timing and previous CDS order reference. Identify unresolved dimensions, material details or special requirements for confirmation.

Contact CDS before arranging to send a physical insulator.
