A lamp holder is primarily made by Injection Molding. Plastic injection moulding injects molten polymer into a cooled steel mould under pressure; it solidifies and ejects as a finished part in seconds. Below is the full route to make a lamp holder, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a lamp holder is made
The usual route, raw material to finished part. The amber step is where the lamp holder gets its basic shape.
Material
Select the polymer grade and colourant for the lamp holder and dry the pellets.
Tooling
Cut the steel or aluminium mould that forms the lamp holder.
Injection Molding
Melt and form the polymer in the cavity to make the lamp holder.
Tooling High (steel mold) Tolerance ±0.05 to 0.2mm Lead 4 to 8 weeks
De-gate and trim
Remove the runners, gates and flash.
Secondary
Where the lamp holder needs them, add inserts, printed graphics or machined details.
Tooling None Tolerance ±0.125mm, to ±0.025mm Lead 1 to 10 days
Assembly
Where the lamp holder joins other parts, snap-fit, weld or bond it into the finished product.
Tooling Low Tolerance good Lead immediate
Inspection
Check fit, finish and any functional dimensions.

Cost
What a lamp holder should cost
The qty-1 figure is really the mold (2k to 50k+ USD) amortised; above ~5k parts it is pennies of resin.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a lamp holder at your volume, in your currency, are in the dossier.
