What does Delrin cost per pound?

The Delrin (acetal) example part

The example part is a two-inch spacer with a drilled center and a relief groove. Delrin machines cleanly when the tool is sharp, yet a tight fit still needs controlled temperature and measurement. The example does not assume a special anneal, color, additive or certification.

How the quantity break works

Purchased stock is a cut piece or bar, not just the finished mass. At a small quantity the minimum stock purchase can be shared across the lot; at a larger lot, volume pricing may lower the material line. Our pricing engine keeps those rules visible in its assumptions.

What the material or process changes

Setup and CAM are paid once. Repeating the spacer across a 100-piece order spreads those minutes, while the turning cycle and inspection repeat. A buyer asking for a different acetal grade should get a new material and tolerance review, not a copied price.

How to turn this into a firm quote

State diameter, length, bore tolerance, packaging and any food-contact or electrical requirement. A clear pound input helps the shop update the estimate when its distributor changes price without losing the process arithmetic.

Questions to settle before release

Record resin grade, color, diameter, moisture condition and packaging terms with the Delrin price. Ask whether the customer needs food-contact, electrical or traceability paperwork. A small cut piece may cost more per pound than a full bar, and the shop may own the drop. Keeping the stock rule beside the turning table prevents a material-only estimate from understating a prototype.

For this delrin price per pound estimate, use the first production run as a check on this estimate. Capture actual setup minutes, cycle minutes, material weight and outside invoices, then update the shop rate or example part assumption that was wrong. That small feedback loop is more useful than rounding every quote upward. It also gives the next estimator a concrete explanation when the customer asks why a repeat job moved.

For Delrin, put the cut-piece minimum and the material certificate requirement beside the pound input. The final release should preserve the drawing revision, stock source and inspection decision with the computed table.
